  1. Note drive a Solstice with the GM Tune and you will know what I have been trying to explain. The other cars are all tuned mild. My SS was pretty much the Regal with just FWD. Same feel good but nothing special. Now adding the GM tune it is like night and day the feel. I have owned many muscle cars over the years and some of these do not even have the feel I have here. To be honest the real sin is the FWD as it has no traction. Contrary to popular belief FWD traction sucks due to the transfer of weight upon launch. I improved the traction with better tires than the factory pilots yet it is still difficult to get it to hook up. Yet the Solstice people still have the same issues as they have 340 FT LBS of torque low down available from 1800-5300 and all they need to do to get it at any RPM in this range is step on it. The feel is very much like the old 428 Pontiac that stock has 390 FT LBS and we would toss in a Ram Air IV cam to add a little bit more. Like I stated most GM 2.0 are in mild tune even the GS as they are tuned for Premium recommended and not required. You can take these engines to 400 HP with the stock parts before you need to change anything.
  2. Because the two engines are tuned differently. The Corvette engine is tuned for more low end grunt. It has some timing variation but is limited due to just one cam. The 3.6 can be tuned for lower end but it is more efficient higher RPM. In a Terrain it is tuned to be efficient. Now GM could easily tune it for more bottom end and to make up for the lack of CID they could add a Turbo. Now with a larger V8 the engine should be able to do anything the present engine can do and even more. The added technology and the fact most DOHC engines are mostly here for more MPG and less emissions they are not for performance applications in most cars. Now the thing is you give a Chevy V8 more ability to breath. You give it more cams to handle the low end and high end and you can toss more compression or even a super charger or turbo for more air. As I know you already know engines are air pumps and the more air in the more fuel and the more cylinder pressure the more power. You can be for sure what they come out with will be as powerful or more powerful than what we have and will have a much wider RPM range of torque. With the large displacement I have a hunch it will be a NA engine and it may hold as much or more power than the present LT4. Cadillac may be going small and T Turbo but the Chevy may be all CID. Then if they want more they can Turbo or SC it. I know the reports of over 1.000 HP testing are legit. I know even the old ZR1 engine passed all the test for Emissions and Warranty at 725 HP with no issues. Chevy will pack as much power into this car as they can and at a price few can come close to. We know they benchmarked the Ferrari and Mclaren so that gives you an idea of the starting point and you know it will be cheaper than it. Even the Ford GT in all its glory will be down on power to what I expect is coming and for less than half the price. The supercar segment is going to get get busy in the $150K - $400K as more companies are now building less expensive models that are still mega fast. The Exotic class is the Million dollar cars but the super cars have created a notch below half a million that will give you nearly the same performance for much less and Corvette will play here and also still cover the under $100K segment.
  3. Yes on mine I can easily smoke the tires at 35 MPG rolling with half throttle. As for my lag the engine has enough compression that initial tip in is fine and the Turbo duel scroll comes in pretty fast. To be honest the transmission kick down has more lag. The one real side affect from the Turbo is the power can hit pretty fast and hard with the torque on tap in a wide range. I have have seen the traction control light come on up to 55 MPH before and the Watergate popped with the loss of traction. The power is more smooth and uniform with a NA engine but that is due to the less ability for the engine to adjust to demands and it makes it's changes more slowly.
  4. Drew the boost is based on how much throttle. Now the difference is much like this. I can give full throttle in the 2.0 and reach full torque from 1800 RPM to 5300 RPM at 315 FT LBS. Now my 3.6 V6 it does not reach max torque till just over 3000 RPM to around 6000 RPM. Same for the 3.0 V6. Both are more tuned for MPG as with other 2.0 engines that make torque higher up. As for a Chevy V8 it depends on the cam and timing. Most build in a steady actual Curve that starts around 2300 RPM and will peak around 4700-5000 RPM with most cams. They have limited timing and limited air due to the size of the valves. The reality is not all DOHC engines have to make high end power they are just tuned there. It was the same on my Chevelle built with a Tunnel Ram where the cam and intake did not make power till 3500 RPM and carried it to 7000 RPM. The timing and phasing of the cam can deliver the power where ever you want it. My 2.0 is tuned more for power and it is a flat curve where the power is available at about any level. The Turbo side of it is just added cubic inches. The Compression side is something Turbo engines lacked in the past as with any forced induction the compression was relieved to make it so the Supercharger or Turbo had room to work. Today with VVT timing and Direct Injection they can do 9.5 to 1 or even higher now with the added boost and make more power. It is about power on demand. No I do not do 23 PSI all the time but neither is a LT V8 putting out more than a minimum amount of power most of the time to just keep the car rolling. The Turbo is a replacement for displacement but it is a variable displacement unlike a fixed displacement NA engine. While a NA V8 has a specific displacement they are fixed to where you can neither decrease or increase the volume of air at a specific throttle position. With a Turbo You can decrease the engine size by just going on displacement but you can increase it also with added throttle and boost. Same is being done on the Z06 now. The fact is before we had improved Turbo chargers and super chargers. Before we had the inclusion of Direct injection and variable valve timing you were limited on the control of the engine. Today these options along with advanced sensors open the door to many more options and the ability to do much more with forced induction. They can so much better control fuel and air now that it gives them the ability to do things never possible before with any engine. Years ago you chose an engines tune when you built it with the choice of size, Cam and Compression. Today all this is no longer fixed and can be tuned as you go down the road. More air can be added. Timing can be changed on the fly. More fuel can be precisely added to cool the engine and to prevent it from going lean but yet still pass emissions. Timing can be maxed with knock sensors. The days of the Turbo engines with great amounts of lag are gone. The days of DOHC meaning they only can make power at high RPM are gone. The days of engines that are not as tune-able are coming to a close just to meet emissions and MPG. Yes they will still make some of the engines with these traits as it adds to the MPG and they are not in performance applications where they need to pull a tree stump out. The reality is We have a lot of good engines and how the testing for emission is done dictate what we get anymore. Also the taxes in many countries are based on size of engine so that has driven the smaller engine market. Companies if they could would all be doing two valve large engines if they could. It is much cheaper and easier to package. Many are envious of the Chevy V8 because of the size but there are limits on how far they can go as things keep closing in on them. Sad but true. Gm has stated they would have to make the change at some point. I see the future of the Corvette mostly being a transition from the present car to a Mid Engine line with various engines and prices. Just because the engine is in back does not say the car has to be $200K. I expect we will see a line from $69K to $200K once they are done. It will not all be done at once either. We will see various V8 engines of both DOHC and two value used. I suspect a V6 will show up at come point with more than enough power too. A hybrid will be in the mix some place too. The Stingray will remain for a while as the first ME will be high end models and as they price them down they will be replaced with ME coupe and convertible.
  5. To be honest I would leave them with the car and leave them with their own damage. They own the car so you can not really take it away but VW can take the deal or pro rate it so they feel the pain as the law was broken and they took the law into their own hands.
  6. I hate to disagree on the turbo engine and RPM. With today's engine and DOHC combined wit a turbo torque can be had low and held all the way up. My 2.0 hits max torque at 1800 and holds it to 5300. I can hit 23 psi before it hits second gear with a automatic in drive. The real issueit traction as you can lose it even with launch control on an pop the waste gate. The last Engine to give me torque like this was a 428 Pontiac. Even then the curve was not that flat and over that much RPM. When you toss 9.5 compression in with 23 psi, variable valve timing and direct injection things are possible that were only dreamed about before. Most engines will not all do this as they are tuned for mpg in a mall cross over so the torque is left for more rpm. Much of this can also be done on a dohc v8 too with vvt also much to do with much higher compression and did to cool the cylinder all with out a turbo. These engines are not like the old and we are just now tapping into what they can do via yeh performance markets. The superchargers are just to get more air in as the two valves only can suck so much in. It is only a matter of tuning to what you want and the regulations that have to be met.
  7. I know from my own work how dishonest people are and in the end it cost the honest people. While the VW issues was a large issue the fact is people keeping parts are every bit as bad for what they are doing. Now if they had VW or the dealer saying it was ok but like you said it was not how the deal was intended. VW will send most of these cars to recyclable and salvage as much as they can. Hate for operate America is one thing but we all must understand the cost will be passes on to the rest of us in one way or another. It is up to the government to deal out the punishment and leave it at that. A public lynching be it a Human or Corporation while it may feel good only hurts everyone. Taking of parts like this is greedy and selfish. It is no different than people burning Hummers because they disagree with people owning them because they are not environmental enough. Right is right and wrong is wrong and there is no between.
  8. The fact is no matter what VW did it does not entitle anyone to steel parts off the cars. Two wrongs are only twice as wrong. VW is being fined and punished. They have paid over value on the cars that are going to be scrapped and I know many are using this point as justification but that is still not right. They are also getting screaming deals on new cars. My boss just got a new Jetta with everything on it for only $210 a month. Not many worth while cars for that price. He traded in his wife's diesel for it. No matter how you spin it there is no honest and ethical way to put it stealing is stealing and this kind of thinking we all pay for it in the end in higher prices. There is no entitlement for anything here other than what the law provides. To take it into your own hands and take from the car in the end could end up making a bad situation only worse. To be honest if someone pulled a car into my dealer stripped down I would prorate it. Also you can not provide anything that this would be legal or with in the idea of how the settlement goes. Sorry but personal social justice or vigilantism is not morally or ethically right no matter how you spin it. What you want to do here is stealing and no matter what VW did it is still stealing. Just because a store short changed you does not give you a right to shop lift. Now if VW did not make a decent offer and provide a good buy back then you take legal action at that point and follow the rule of law.
  9. It is like people buying a mower at Walmart in the spring then returning it in the fall because now they did not like it.
  10. To strip and return is like damaging an item or theft. VW has given a generous settlement and blazing deals on a new car so asking that the car comes back complete is little to ask.
  11. The sound is more cylinder count and the degree of the block. Some combos sound better than others. My eco sound like a fart can but has power and torque. My 2.8 V6 sounds like a 308 Ferrari but has little power. Even an old 318 with thrush side pipes sounded killer but had no power. My buddy used to get challenged all the time but he has to tell then it was just a stock 2bl Dart Sport. Another buddy with a first year Viper said it sounded like school bus with the V10.
  12. Just look around they are rare. Sadly so many people can not drive one today. If a dealer gets one the make good deals on them to get them off the lot. I have nothing against manuals but the harsh reality is we are not far from seeing the last common one soon. Who ever thought the famed gated shifter would be gone from Ferrari?
  13. Now the reality of more than 5% of people actually buying one. Also meeting emission easily.
  14. I get 300 HP from 2.0 liters and it still has more room to grow.
  15. The thread should have come with the stipulation that the realities of scale should be included. Any idea should make money and meet all the criteria automakers face in the real world. we get enough dreaming on the web as it is.
  16. Priced a Z/28? Coul be under the zr1 hood now. Have you heard one? This is not a case of doing this beuse everyone else is. This is a case of if you want to meet future emissions you will have to do this. The flexibility of the timing and extra valves make for more power and better emissions.
  17. Well here is the deal. This is needed for Emissions that need to be met. But like with DI there is advantages. The reality is there will be more than one version here. I expect a supercharged or Turbo to appear. The Zr1 will see 725-750 HP easy with the added down force. It is reported that the new Corvette was testing over 1000 Hp but the un named Corvette person said they would only use what they could put down. Now considering that private tuners are already hitting 1000 HP with the present engine emissions legal I tend to believe this to be true. Also the Corvette team has always given as much as they can use. They know large numbers mean little if you can't put them down. I also ponder will the Z/28 get this also is this a base for the coming DOHC Cadillac engine?
  18. I get it so there is no argument. #1 was my point. #2 was part of my point. They do have military graded materials but that vary by application. They have specifications for pencils too that is also considered a military grade. #3 was just my illusion of Fords marketing making it appear as if they build tanks with it. An airplane also has military grade skin on an air plane that I can push an ice pick though. Means nothing. Note they built and reman the M1 tanks near me so I am well versed in what they are made out of. This is a case where you missed my point. .
  19. It is coming about 2 years sooner than I expected. With that we may see this in the ZR1 and Z/28?
  20. Understand this what I do not understand is it worth the risk as you too often end up with issues like this as people really don't deal with changes like this well. The space is not worth the issues.
  21. You my friend underestimate the public. Years ago a Ford engineer told me that they could paint a car with no orange peel but they chose to leave it in. Why? because they found folks saw orange peel on a Benz and believed it a was a sign of high quality because the paint was thicker. Ford marketing is doing the same with their comments as if you asked most few could accurately discribe what military grade is. Yes there are many idiots out ther and they drive all brands. You appear so butt hurt if you have to be so defensive over 300 pounds on a truck that will need to lose more in the future. To be honest I see the Ranger as well as the GM mid size replacing the half ton and the 3/4 ton taking the full size lead slot. The regulation as they are now favore this unless it changes.
  22. Global domination is now being fought fiscally. Get use to it. At least now we may try to work some better deals vs to apologize and play dead.
