Went for a ride in a procharged vehicle today... So today I popped my procharger cherry today when I went for a ride in a 2000 trans am.
The car had a built for boost stock cube motor with a 12psi pulley installed. I was very dissapointed to say the least. The car made 12psi at 6200 then it shifted at 6500 which was only about a span of 1 second. The boost dropped back down to 4psi then slowly it crept back to 12psi but then it immeditally shifted again . Is this what all prochargers feel like? The car felt like it had a intake, exhaust and a little bit of tuning but nothing like you would expect from a FI car.

a 347 on 12 psi of boost would be around 600whp mark and i do not really consider that weak. if you are used to driving 1000+ hp cars then yea it is not going to feel too fast.

I agree, something doesn't sound right with this combination, maybe the car has 2.73 gears. Bob

Definitely something wrong.
I don't have that kind of power (stock bottom end with about 8 lbs) and everybody I have gave a ride to was quite impressed. It didn't matter if it was a 2nd through 4th pass or just blowing the tires away 1st, 2nd and shifting into third.

What does it run at the track? I've seen FI ls1s go 12s and slower at the track and that is not going to feel that impressive. If the car was set-up correctly with 12psi is should be in the 10s, and that feels very impressive, almost scary on the street. My D1 made 14psi on the stock block and went 10.1 in the 1/4. People were scared when I gave them test drives, one girl almost pee'd her pants and made me pull over lol. Big difference in how individual FI cars perform. If it had 12 psi and felt like a intake & exhaust car, it's not set-up right lol.

i think what made it feel slow was how the boost dropped so much when it shifted. I have another friend with a aps camaro and when it shifts it goes straight back to max boost instantly.
Do the magnachargers have a linear boost curve like the procharger? I know there are some fast procharged cars out there but I just can't see how they would compare to a properly set up turbo system.

Doesn't sound right at all. My GTSLOW has no problem going to warp speed. I break traction at 80 no problem and burn the wheels off anytime I hit the go pedal. Are you sure the car wasn't spinning so bad it felt slow? It will be another ride with some DR's on it.

Sounds like a combo issue or overall problem with the car. I have a stock cube, stock internals, SC ground cam for boost, at 12psi.... 651rwhp. Like someone mentioned.. when I hit the pedal its freakin warp speed.

This might be a stupid question, but did the owner have it tuned and do all the necessary supporting mods (fuel, etc)?
