Exactly how much power can a s/c 3800 II...

[Flybrian]

Yeah...?

[Intrepidation]

A lovely potato for you! (because I don't know the answer to your question).

[Drew Dowdell]

a little over 300 for the transmission?

[76ChevyTrucker]

I'd say probably somewhere around 300, even as much as 350, but probably not much more than that. The 4T65E transmission strapped to most 3.8s, even the s/c'ed ones are fairly beefy.

[Flybrian]

Over 300? Good to know. Thanks.

is it the hp or the torque that will have the greatest impact on the tranny? it already has 280ft-lb!

[76ChevyTrucker]

Truthfully you make the most horsepower at high-er rpms, and since the transmission has to spin normally 3 times faster to transfer the power from the engine to the ground, when its spinning about 4 grand, the transmission is spinning about 12......so I'd say that the torque would be worst to the axles and differential portion of the transaxle, but the high-rpm would be more harmful to the transmission.

[daves87rs]

About 340, I think.

These things can take a lot of abuse...

[CaddyXLR-V]

Speaking from experiance, my transmission could only handle about 320ft lbs, and 280hp, then 3rd gear started slipping and I had it rebuilt with kevlar clutches. When it went bad, all I had done to my car was a reprogrammed computer, and a smaller pulley. The engine itself can handle alot more power.

Not sure about the transmission but the engines can handle quite a bit, with out to many mods.

One of the places that offers mods (www.zzperformance.com) has turbos and intercoolers available.

One of the Grand Prix's I saw on there was making over 600 hp.
