hyperv6

Because you can't fit a V8 in a Sonic, and you shouldn't put a V8 in an Impala. The V8 will survive. It may require hybridization and/or turbocharging to do so. But it will. Oh we will have v8 engines but they will very limited and very expensive. Big picture! If the v8 held that much mpg potential we would not even have a sonic.

With many media outlets anymore if it bleeds it leads. Also with many in the media they are no longer unbiased and generally socialist and anti capitalism. Too often media is agenda driven.

It does not evaporate. It turns into a vapor as it has to do to compress. Unless you found a way to compress liquids. The last time I tried that I broke a piston. The cooling is just a part of vaporizeation and the fuel never leaves the cylinder. They do the same thing on the new LT engines even with out the turbo. Putting cooler fuel in the cylinder drops the temp but uses no extra gas. That is the whole point of DI along with placement of the fuel and specific amounts in the cylinder. This is the most intelligent post on this whole thread. Thank you.

Drew lets put it this way if the MPG and Emissions were just as good in a V8 do you really think they would spend billions on two entirely new engines? The V8 with cylinder drop is still more V8 than 4 cylinder. Also they are no longer the simple cheap small block of the past. Also with the new turbo engines they often have more low end torque. Like I stated get it up to speed faster with the more torque and get off the gas sooner. That is how the GM performance driveline engineer explained it to me. If the V8 was the superior engine for all application it would be the engine in all the applications. Also the issues with less weight are now real as GM has removed much weight from the 4. That is where much of the Malibu weight loss came from. Now in performance applications and trucks the investment is still worth it. But yet while some want to live in the now MFGs have to worry about 10 years and beyond. You have some legitimate questions and I think you do know the answers and are just looking for conformation. I am anything but anti V8 and you know that but to make sense of this you have to say or point out some unpopular things to some people. Again like I like to say this is big picture. The thing that surprised me the most is how Ford made the move as early as they did. As it has gone things went smoother than I had expected. God knows I would have hated to be the one that made the call to put a TTV6 in a truck. That to me was a much greater risk than Aluminum in many ways. Also we lust factor in that the V8 is running out of things that can be done to it to extend MPG. GM has done a great job with what they have done but how much more can be done? On the other hand the smaller engines are at the beginning of their runs and still have many things that can be done. In the future we will see engines get stupid small and most all will have a turbo sitting somewhere on it. You put a Turbo on a BMW to look like you have advanced technology. You put a Turbo on a Cruze because you are trying to meet fuel and emissions goals. I don't thing GM really even publicize the Turbo all that much and most people may not even know they have one. I think you can get my point. You may not agree but why else would they spend all this money on more and more smaller engines? Answer that one.

Honest question to the powertrain engineer. If two engines of two different cylinder counts are using the same amount of fuel per mile (assume that it is true), Also assume that things like combustion chamber and fuel delivery are the same, wouldn't those two engines have the same level of emissions? The mileage is in most cases just a little better but generally they can do it with out cylinder drop and other tricks. As for emissions it generally better with multi valve. That was the whole reason many companies went to it in the first place. It is about volumetric efficiency. In most multi valves they can place the valves in more places to move more air than one large Intake valve. Ferrari had gone to a 5 valve just for this. I am not sure their new turbo still has 5 but it was for efficiency mostly in emissions. This is what I was taught in collage. The engine is an air pump and the more efficient the air flow the more efficient the engine is. The added valves just opens the door to be better at controlling the flow. Add VVT to it and it makes it all that more efficient in both areas. Add DI you can better control the flow and placement then add a Turbo and you can cool the cylinder and add more compression and more boost. I run 23 PSI on pump gas with no issue and with full GM drivetrain warranty. Now that they have added the VVT to the V8 push rod it has gains some in this area but with two cams you can even get a little more out of it with 4 valves. No one thought it could be done but GM has done it. But yet they still have to drop cylinders. I expect more 6 and even some 4 cylinders to get cylinder drops as they really are getting desperate Anyways with my Turbo even driven hard I easily beat the EPA number driving it hard. 25 City and 32 Highway. One thing many people do not consider is if you leave a DI engine in gear and lift off the gas the engine cuts the fuel off not matter what engine. Coasting gains much in MPG. The GM engineer said the trick with the turbo engines are they have so much low end torque they can get off the gas sooner and gain much more MPG.

Have you really spent any time with a Turbo DI engine of 300 HP? I have and I would hardly call it adequate. Is it an SS or GT? No but do you see that emblem on it. My Turbo will run tight with some 13 Sec V8 cars if I can get it to hook up. FWD suck but the engine can deliver times better than many big blocks of the past.

But again the Hellcat will not be around long. Smoke em while you can buy them. The 4 is going to be a major part in the future. You start promoting it now not 10 years from now when you need it. It is simple we have three engines with three diverse attributes and three engines that appeal to three different kinds of buyers. What is wrong with this? We will have a second SC V8 soon there is nothing wrong with any of this.

http://gmauthority.com/blog/2015/09/watch-chevrolet-take-the-2016-camaro-turbo-drifting-video/ The 4 is not all about Fuel economy. It has two sides you can tap.

Yeah...but...if its fuel eceonomy you seek...you stick to the 4 cylinder... If its medium power with moderate fuel efficiency....you stick to the 6 cylinder...and if you want raw power... With Ford...buy an ecoboost 4 cylinder for fuel economy.... or Ill rent myself a Mustang from Hertz for the week-end... Ford's I4 Mustang offers it's best fuel economy, and instant torque that feels like a small V8. How foolish would Ford be to offer this for less money than their far weaker V6. Nope...nope it doesnt feel like a small V8...it feels like a turbocharged 4 cylinder car... Weaker V6? Only because Ford chooses it to be weaker...and muffled...and stifled...and left behind to rot in rental car parks... My Eco Turbo with the GM upgrade does not feel like a V8. I never had a V8 spin the tires at 50 MPH and turn the traction control light on. The first time it happened I thought I broke something when the waste gate kicked open and the light came on. The Torque in the turbo engines has such a flat curve it will do thing a V8 will not do. Now the V8 will always sound better. Ford is not taking a high risk here as this is where all this is going. They are trying to establish engines now before they are forced on the public. The time is coming it is not just a good thing to offer but something you must offer to meet different regulations. I don't see what the argument is all about. All three engines are offered and you can buy what you like. Offering a smaller V8 is not going to make it any cheaper do to many reasons. Right now I like what GM offers and wish they would bump the 4 to 300 HP but they want to remain Premium Fuel Recommended. At least offer the tune kit like my SS as I know they can go at least 340 FT LBS as they did in the Solstice.

If you could choose the 3.6 or the 5.3 for the same price, which would you choose? The 5.3 is cheaper, lighter, and more powerful with much much more torque than the 3.6. With AFM, the 5.3 would likely post similar highway MPG. Drew this is not about what I would chose but it is about what choices GM will offer me in the future. God bless the V8 and GM has done a great job with it and may be the last of the three domestic to offer it in many vehicles. But the future is where everyone is building and smaller engines are where they are going with Turbo Chargers. It is not just MPG but also emissions that they are faces with. Lets face it I think Ford knows the needs of the future much better than anyone here and they are nearly dead with the V8. they will have it in the Trucks and yet in the Mustang for a while longer but they are now building a Supercar that will be a TTV6 and even the Raptor. Ford has show with these image products where they are going. Word is the Hemi may die in 2019 per the Chrysler web sites. It may not be too hard to expect as they do not have the money to dump into the Hemi like Chevy does with the V8. I know the 5.3 gets good MPG for a V8 but my 3.6 gets just a little better. At this point even a part of a MPG will be taken if they can get it. The plan I expect from GM is to keep the V8 in the larger trucks, Camaro and Corvette but even in the Vette too I expect a TTV6 as an option. They will offer the V8 but it will only be in the top end models and it will be expensive to limit sales. I am pleased they are hanging on as long as possible. As for most normal cars like my Malibu and Terrain the 3.6 is all they need. They are not performance cars and I am not left wanting entering a freeway. No need to go farther. As for Camaro like in the Mustang the V6 is bought mostly by women. They love the little bit better MPG and the cheaper price. They are not street racing. Ford was 50/50 on sales and I know GM would like to match that with their Camaro. My wife's friend is the perfect example. She bought a Hot Wheels Camaro and bought the V6. It was all she wanted and is very happy with it. To be honest it is about as fast as their 4th gen LT1 that is modified a bit. The bottom line is they offer both and you can chose what you like. It may not be too long we may not have that choice.

Well here is the deal. GM did wrong with the Cheap switch and should be penalized for it. Their damaged culture made this an easy thing to hide in such a large company. Odds are one or two people screwed up and covered their asses. There were some people let go but many had already left with the bail out so some may have already been gone. Now where I do not agree with the settlements is where drivers who died because of their own actions after the ignition cut out. The simple facts are this. The columns do not lock and the car generally can be turned enough to get to the side of the road. Second the Air Bags are a secondary restraint and need to be used with a belt. Brakes were still operational as with the check valve in the booster you get 2-3 stops with full power assist. Finally a driver with all their faculties generally can shift to neutral and restart the car. Many of these accidents could have been avoided and many of the deaths were due to the choices and condition they put themselves in, My point in these cases is GM should share responsibility but if the driver was impaired, not belted and or speeding or in an out of control condition they also too should share in this. To be this is like the case we had locally where a driver of a Blazer hit a tree drunk at 90 MPH and it caught fire and burned him to death. GM was not allowed to add in the driver was drunk at the time of the accident and the fact that hitting a tree at 90 MPH could result in a fired that could kill a person impaired. This was a case where a company did screw up but in many cases so did the driver and many times it directly resulted in the difference of them living and dying. The ignition may have contributed but the 70 MPH in a 25 zone, drunk and no belt was the life and death part of the equation. The one good thing that did come from this for GM is the fact this went down around the time Mary was fighting the old Culture people still in GM after the bail out. This pretty much shut them down and let her make the needed changed to fix many of these bad culture things. Lutz started the purge and Mary gain a lot of traction once this issue came up. Because of it today GM is farther along with the correction to their corporate culture than they would have been with out it. It is sad it took this but at least some good came of it and it will help prevent this from happening again;. It is good when a company does become better due to a crisis but too often they don't. Not all customers are innocent and not all corporations are corrupt. Each side has their share of good and bad. That is just human nature and the right culture will help keep it in check. The GM culture was so bad they would often time do more damage to themselves. Also to bring people to trial is not easy in cases like this. Odds are the evidence to all involved may be circumstantial at best or we would have seen the government take specific people to task. We have to remember this is the company so incompetent as recent as 2005 when asked by Lutz why they could not make panel gaps as well as Hyundai he was told we can but we were never told to do it nor could they ask. Yes it was that bad inside back then. Not an excuse just a reflection of what was going on and how bad it was. They could not even take care of themselves.

I too have speculated the Avenir would be coming. I really think the only delay is the CT6 reaching the market and the new Lacrosse coming next year. I would peg 2018 as the year and guess what that is the year the SS and Holden both die. About then the Impala also is need of update or replacement as it will only have till 2019 if it is kept on line at Oshawa. We know the XTS that is on the same line I believe is good till 2019. Either way moves will have to be made and these models fit together with a time line that is plausible. Yes Buick will get a new Lacrosse next year. The Regal should be in just after it. as for the mid size CUV there is one in China just ready to be built here. The whole thing about importing them is just a UAW negotiation tactic. I am wondering with word the Terrain may be moving to Spring Hill with the SRX if it may on the longer version and the Buick will be on the shorter Nox Version. That way they do not step on each other at the dealers. Also we have one more mid size SUV coming too. We have yet to hear much on it but there is one more in the mix. Build the car right and the name Impala will help with the older buyers and introduce the newer buyers. They may be young but with so many sales over the years with Impala and Caprice the equity is hard not to use.

Here is what we are reaching for. Power is indeed what most people aspire to. For some it is the power of leadership be it the head of a city, country or company. For others it is large amounts of money and influence. For many it is what we can buy like large expensive houses and powerful cars. For years for cars to represent power has been in the engine. We saw it way back even in the powerful cars of the 30's or even when Edsel Ford brought the world the Flat head. With no regulations and no worry on gas prices the door was open to make more and more power. The only limiting factor was the inefficiency of the engines build on lower technology. Today we have advanced the technology and the investment into things companies would not use due to cost to make smaller and more efficient engines but with much more power. We have pretty much it a wall now as cars like the Hellcat have a lot of power but really can not use all they have put it to the ground in stock daily driver form. Now we are entering the next stage where lower mass is the new HP war. As cars drop in weight more performance is found in shorter stopping, better handling and faster performance. Do we need this no we all could really live our lives in a Spark but that would not satisfy the needs of image or expectations of most customers. Drew the truth is DOHC has played a part in this as they are very efficient and powerful small engines but they also equate more is better to many customers and that is where the addition of technology enhances the image. To some just having a Turbo or Supercharger means more in image. Sale for DOHC and other technologies. The engine is an air pump and to make it more efficient you need to get air in and used power out. Now with the push rod they have done very well but we are now to the point GM is working on dropping a V8 to two cylinders. Lets face it at some point they will hit the wall. Smaller displacement engines with more than 2 valves are more efficient in getting air in and used power out with lower emissions. If this were not true for smaller engines you would still have them investing in the Iron Duke. But that is an argument for another day. Back to deal here. A Z06 is really an AK47 of the automotive world. Does anyone really need one. No! But do you feel more powerful with one and feel an enhanced image yes!. Power sells just as bigger, better, faster and Sex.

I think you are over thinking this. As it is now the Impala is for the most part not nor is it expected to be a Volume model. It under cuts the lacrosse fine and makes added income off the platform. This for sure is a low risk no brainer. Now my thought here is one the Impala name is not damaged. Second many people still equate the performance models of the 60's with the name. What I would like it to see this car morph into what would be a 4 door Camaro with out being a Camaro. We would have styling of it's own and make even more use of the Camaro parts they have made up. The price would be such that it would entice people to pay more for a RWD car and the profit per unit would go up. This would make more money on a lower volume car. Lets face it the Impala as it is now can move up more because one people would not pay it for a FWD car and we already have a Lacrosse. Then for Buick you keep on offering AWD and add the AWD and RWD Omega. The name Impala would not change a thing about the present car. What many fail to understand or realize is the SS was a program from way back around Chapter 11 time. For what all the reasons it got here late in the game and was pushed through. I had a talk with the head of the GM RWD Performance platforms Oppenhiser years ago and he told me then the car was coming but there was no set time for reasons he could not give. Like the present Malibu the SS was a vehicle caught at a time in GM history where things did not get all they could because of the amount of time and money going into other projects. Some of these models were just to keep the line up fresh as they finished the Alpha and other things that would carry them forward. If GM had not used these still born models they would be like Chrysler struggling on with older models for 5 years or more. GM Dumped money into these models in 08 to try to get them to a point they could be taken off the shelf when they could to at least offer something new. Even the ZL1 was one of these projects. I just feel there is enough to build a business case for an Alpha RWD sedan at Chevy in lower volumes. It also could serve as police fleets to help round out profits. This would also help put a different twist on Buick and Chevy too. This model could also serve in most LHD markets the Holden is in too and be exported out to the Middle east etc. While the Impala had some lean years it was never seen as a failure and the equity of the name would be fitting. They could even use it in conjunction with the Caprice name too. Lord knows the Impala SS of the 90's is still a very popular car as the prices continue to climb.

The limitations of this car are many,. Some self imposed by GM for various reasons an some due to circumstances. Some of these we know why well and some we will never know. It is what it is. I am just hopping there is an Act 2 that we are not aware of yet. I would love to see a melding of the Impala and Camaro into a full line larger sedan. This would remove it from the Malibu that is growing in size. It would offer a lighter RWD car than what Chrysler has and what Ford does not offer. It would still provide a police version. Finally It would give a chance to offer it in a 275 HP 4 to a 455 HP V8 or more. Being on an Alpha would help control the cost of a lower volume model. Lets face it this size car will never sell in the numbers the original Caprice of the 80's did as the market has down sized. Make it with a different body but make it more Camaro under the skin. The suspension should carry pretty much right over accept for spring rates. I hope the silence on the Impala and SS hold more than they might. I know it is something Mark would approve of but can he make the business case to get it approved?

The whole point of where we started is just a simple observation on todays performance vs. mind set of some folks out there. . Lets face it the 4 cylinder Camaro has gone from 95 HP to 275 HP. Even some of todays cars that are un restricted are insane and there is always someone out there willing to try them. Case in point. My HHR SS with the upgrade will do 160 MPH. Now who in their right mind would want to go that fast in an odd shaped box? I tend to restrict my demonstrations of speed to on ramps and then blend into traffic. But on the HHR site there are a few who have tested these upper regions. So far we have not thinned the heard but at some point one of them will make room for a new birth. I am comfortable with the 0-60 but others love to over reach in the wrong places. Just human nature to some. No one ever called for everyone to drive smart cars just an observation of the hey watch this mentality and what more HP will do for it to a minority of the buyers. It is like the guy who bought the Mustang a couple years ago. It was a V6 that was speed limited. Well he took the limiter out. At about 150 MPH on the highway the driveshaft let go as it was not made to run with out a limiter. It came right up through the floor. He was lucky not to get hurt. Then the idiot puts it on YouTube. I bet that did not help in a request for warranty repair. How would you eve call your insurance company? Again just an observation of human nature. We should not limit these cars or HP for the minority but we should expect to see some go out in a blaze of stupidity.

Drew there are adults that should not have this much power. Anyone seen the Prince in Beverly Hills in the Ferrari this week? Also the videos we have seen on YouTube of the crashing Z06 are proof that many people are over their limits.

I see it on the performance side of things since that is where I work. Kids today wither want faster phones or pads than cars in most cases. If they do favor cars they tend to look to the smaller and lighter cars as they can not afford the insurance and or the payment of a newer Camaro or Mustang unless subsidized by mom and dad. Also the used market is slim pickings as often the Camaro's and Mustangs are still expensive insurance wise and often the cars are beat to death. Though I do find deals now and then. I just had a friend sell a 2002 Z/28 that ran 12's and was well built with 17K miles for $9K. But even that is hard to afford for a kid working at Mc D. I had it good as in my time I could buy old 60's Muscle cars for $2500 and insurance was cheap. I had three at one time that today would sell $25K - 30K. Today a kid can buy a Honda cheap and they grew up in the back of an Accord and they are happy with that. There are enough parts out to make it loud and a little faster but that is all they care about. The Camaro is targeted at older customers with fluid incomes that can afford these cars and grew up with them. Over time we know they will have to down size them and I expect they will target the kids of today and the start of that is the Turbo 4 engines we have now. That 4 is not so much for the people today but to build to the customers 10-15 years from now. Like I have said the Pony car died years ago and these cars today are more GT coupes. They are going to be more refined and will compete better with more expensive names as we go on. They are no longer just converted economy cars. I have been to about any kind of race you can think of but F1, I should have gone to Indy but just never did. I will get to one someday. I really would love to see Monza. I would be dressed in red.

BZMW is not going to lose a lot of sleep here on the Camaro. While the Camaro and Mustang performance wise will be as good or better the cars hold a different appeal. Many sales of BMW are not as much for performance as image. People buy because they want to look affluent and sophisticated. The Camaro and Mustang while moving closer is still seen as a working mans performance car. While models like the ZR1 and Z/28 have help to start to change that they still have to work on rebuilding the Joe Dirt image some have placed on them. Doing sales globally may help change this as people overseas have a mixed view but many like the loud and brash performance of the American coupe. If there are more of these in Europe it could help morph the image here. The Cadillac line will take care of the customer who see's him or her self as more sophisticated. They want the more quiet exhaust, they want the smoother ride, They want the more high end interior. The fact is there is a place for both cars and with the ATS offered in a Sedan it will see more sales here anyways. The truth is the Camaro and Mustang are the only 2 two door coupes that hold much volume today at a lower price. Also look for the ATS to change much with the move to the CT4 name. They will not just changed badges as they will make some major changes to the car and fix any area that was not addressed properly like the interior in the new car.

It is what it is and never was intended to sell in numbers great enough to make it profitable with whole sales changes. It is a car where the circumstances and the time it is built and where it was built have conspired to hold it back and bring its end. I am hoping the new GM culture has plan to move a similar model here built on the Alpha and merge it with the Impala. I am not holding my breath but you always dream. The best thing in the world was this was a Holden or we would never have had it. The worst thing is it was a Holden coming from half way around the world from a market that sells less cars combined than the Camaro alone.

The new Civic has a turbo 1.5L that puts out 174hp(no tq rating though). I would assume it would be no less than 174ftlbs with it being a turbo. Yes with a DI Turbo and VVT it should hold more torque than HP. 1.5 will be a popular size engine as the engineers have documented the best sizes for power and MPG. 1.0, 1.5, 2.0. 3.0. 4.0 Turbo engines give the best results and that is why most companies are all using the same size engines. It is not just a coincident that they are all using the same numbers. Now how much power depends on how far they are pushing the engine and balancing the MPG. Car weight plays a big part there as mass is the next HP war. We will see a weight war with all MFG and GM threw down the first challenge with 300 pounds in a important segment. The Cruze too in base form may even hit 2900 pounds. We will have to see where that goes.

I have to heartily disagree here. The 2002 Camaro had no bragging rights besides the straight line. Japanese cars for the same money handled better, felt better, braked better, and didn't have a penalty box interior. Asking if the new interior is worth $7000 more, I'd be inclined to say yes, absolutely, because I'm reminded how much I can't go back to an old GM interior every time I ride in my fiance's Cobalt, but that's a misleading question because it ignores everything else that's state of the art about the new car. Or the fact that the $30k V6 will nearly run LS1 numbers. Former Camaro engineers openly admitted that GM gave them just enough money to fully develop the drivetrain and virtually nothing else. This Camaro is the first one in decades with zero development compromises. The Alpha chasses, now THAT alone is worth $7000 over the old LRA sled. The rest of the 2016 Camaro package is icing on the cake. I will back you up on the 4 gen. I was sitting with Scott Settlmire the head of the F body program when he told us that the car got all the money for engine and suspension but not much else for the details and quality inside. He said "This is why your power window fail". I think once people get to really see the new car here and drive them they will find the first most completed Camaro every built. Like the C7 while not perfect it is the best Corvette ever made and lacks many of the things it used to fall short on every year. As for not perfect it is close but when the price is considered nothing else is close for what you get.

No it is a supercharged Camaro. What I like is how smooth and fast is appears in the video.

I have seen more harsh comments made. Both sides need a little thicker skin here. This rivalry is what has kept both cars alive and popular for as long as they have. No rivalry then you get sales like the Scion/Toyota/ Subaru coupe where few care and sales struggle. Guys make your comments, post your points but keep it fun. You need both sides here to survive. I just lost a good Mustang friend. We beat on each other hard but in the end of the day we both realize both are decent cars and kept it fun. He had a Shelby and it was an amazing car. Note this was one of the real Shelby's converted in the 90's at Shelby not a production line car. It even has the performance upgrades but no spoiler. Rare car. He just passed away and I will miss my Mustang arguments with him over the new Camaro. That and he was a Michigan fan and I an Ohio State. I used to decorate his cubical with Buckeyes every year. We have gotten to an age we need to appreciate each and every performance car we have left. You may still argue about who is better but we need to keep close to one another as we may need the support for our favorite to survive.

I was lucky to be around John Lingenfelter back when he was racing the Eco. He was using the stock block and head up to 1500 HP before the head cracked. It was the Saab version that the LNF was patterned after. I expect the Ford also will be able to take a fair amount of power because today the MFG are not short cutting these engines and are building them to take much more abuse than ever. I see daily 23 PSI of boost and back in the old SVO and GN days 12 PSI was a lot. Things like Sodium valves, the pistons are oil cooled the DI cools the cylinder, standard compressions have risen. The crazy part is how stiff the Ford and GM blocks are now and they are lighter. The Ford is a good engine but the GM is as good or better but they did such a bad job of marketing it most people have no clue. Anyways I can see the after market taking these engines on and doing much with them. The only question I have is how will the insurance companies deal with them. Will they swack them for younger drivers or will they give them a break from the V8. If they give them a break the younger buyers may take interest. These cars can be the American Skyliner. It is not easy to drift a FWD Civic. Block and heads can take a lot. I assure you that he did not have stock bottom end though, iow, he had stronger rods and pistons, bearings and probably crank. Block structures are easy to over design, given modern CAE tools, and with minimal impact to weight. So we do just that, which often assists in NVH. Oh for sure he had full race parts like crank, rods, pistons etc. I have the GM numbers on what part will take what. Here are some examples on the LNF. I have covered Rods and Pistons to 400 HP. Valves 400 HP Cylinder liners 400 HP Head gasket 500 HP Crank 500 HP Wrist pins 600 HP Exhaust rockers 700 HP Head casting 900 HP Block 1000 HP GM has build several cars including the pro drift Solstice with the 500 HP version of this engine. It was very street able and very durable with no teardowns during the whole season in drifting. Back when John was racing this engine they had not yet gone Turbo from the factory and also he was the first to race it in drag racing. There was little aftermarket parts so he used stock and parts his company made to make it stronger and faster. My Point is the engine that is now 250 HP in the Malibu can handle up to 400 HP with no modifications other than those to add boost. What is holding GM back from 300 HP is the Regular Fuel recommended and not required. The extra boost moves the fuel up. GM has to look at the fact that people in non performance applications are reluctant to buy premium fuel even if it only cost them a couple buck a fill. They like the option and that is where we are today. I had a talk with a GM brand manager about this one day when he invited me to Michigan for a visit.
