Help Please With Gtp

[Sublime22]

--------------------------------------------------------------------------------

Sorry. Does anyone know what the stock PSI Boost on the 3800 SC for 04 w/compG package?

I have heard 5PSI and 8PSI.

What is a good size pully to keep the car streetable, but weekend only car.

If you did not know by reading this, I only have experience with older motors and all V8, since I had a baby I had to get something to satisfy my need for power with 4 doors, so I know nothing about fuel injected or boosted motors.

Any help I can get would be much appreicated.

little old post, but a 3.4-3.5 pulley is as small as you want to go on your 04 because yours puts out more boost than the97-03 gtp's. without headers, rockers/cam, and/or intercooler, you wont be able to run anything smaller safely...
