Im not considering actually doing this, but what is the capabilities of a TT V6 for a daily driver. What kind of power would it possibly put down?

 

around 350 hp and 400 tq i would guess.

 

thats not too bad for a 3.8L. Was thinking back to the 80? Turbo T/A with the 3.8

 

Very different engine... the old 3.8 from the 1989 Turbo Trans Am is based off the same engine found in the Buick GN. Very capable Engine. It was a single turbo though, BTW.

 

Ive done alot of turbos on 4th gen v6s...

Ive easily put 330 rwhp and 400 rwtq out of a 3.8 on only 7 psi and no tuning, THey have quite a bit potential. It was a custom T70 kit I built, bone stock motor.
I expect near 350 rwhp at the same boost level once its tuned and has the fuel it needs. near 400 rwhp at 10 psi.


With a smaller to4E 57 trim another car still made 295 rwhp and 360 rwtq at 7 psi and wwas on its way over 350 rwhp and 420+ tq before locked up the injectors, stock tuning/motor.


Things will get interesting now that HP tuners suports the v6s opened up alot of possiblities, soon it will be easy to reach 400 rw

 

thats cool. Hows the turbo 4th gen V6 compare to a ls1 as far as performance? It would be interesting if they brought back the firebird and offered a turbo v6. Although ill take a LSx any day.

 

Cal Hartline down in Florida (Hartline Performance) has a daily driven 8 second Grand National with a T88 on it. He runs 36 lbs of boost at the track on C16. A T76 on a GN engine with a proper setup can get you into the nines.
