Cadillac should build it this way.

For the OP, belt slip or rear gear is too high.

Check your boost gauge.

Something is obviously wrong, if that is what prochargers actually acted like no one would be buying them. And they wouldnt be able to keep up with simular power turbo cars. Heres a vid of my friends hpf m3 vs a s/c z06, close in power, near the middle of vid.

I agree with every one else that something is wrong. When I shift and the pedal goes to the floor the boost gauge snaps right back to 10#'s and then goes to the 12# mark by 6,500 rpms. This thing scares the **** out of me, by the time I let out in 4th at about a 140mph my hands are shaking.

Yea those hpf turbo kits for the M start around 15k... LOL!!! ridicilious

yeah yeah **** off i see it.

camarosam22

Yeah their pretty exspensive, as is anything related to a bmw.

Smearin

They would def. be more attractable, but thats just a little too much $$.. I like the new e92 too.

I have had rides on two ati cars. One was near stock lt1 and buddy ran it against my car which had headers and cam at the time, buddies car which was near stock ls1 and other buddies ls1 with heads,cam/headers bolt ons. He couldn't beat the heads/cam /header bolt on car so he went home and tightened up his belt and blew a ringland. His car was not that much faster than my headers cam bolt on car we were close to even.But again this was a six speed near stock think it had headers lt1.

Buddy bought an auto d1 ls1 and I got to drive and ride it. It was not that impressive either but was at only 8psi stock engine with maybe headers. It had stock stall and not sure gears but it was pretty doggy.

I am not saying though that a properly stalled up say 3.42 or 3.73 auto d1 car would be slow especially at 12psi.Sure it would rock out pretty nicely.
And ditto on a six speed it really should have 3.73 maybe even 4.10 gears to get that thing revving quick and up into higher boost faster.Tuning of course is still pretty important with timing being really important. Afr not quite as much but if there was knock retard happening that can really slow a car down.

I still like the way turbos hit,especially my twins and they already pull hard but its a built 408 and even at only 8psi or so likely have 650rwhp and 700 or so torque from looking at similar bulids. As you said you had ride in your buddies aps car.
The aps spool up pretty quick. Even quicker on my bigger engine. I need to get some logs to see just how quick.But think they are like full by 3000 in third gear on the m6 which is still in there.

Anyway I think prochargers are still pretty good and still want one for my 96z .
If you want even crazier with turbos or supers get some spray and hit it with even a small shot like 75 or 100 shot and see how quick turbos can spool and how quick bet that car would rev which would of course also help the supercharger get into higher boost.

Thats still where bit of misconception comes in .The procharger does not have the lag of a turbo technically but it still can't build full boost until it hits high in the rpm band. The turbo can take a second but it can hit full lower say 3000rpm. So the turbos normally have much better area under the curve and wider powerbands.Just compare any two similar charts of centrifugal and turbo. Course you need to compare similar units in terms of airflow.

All fun toys. But yeah car should still have screamed at 12psi if things were optimized.

camarosam22

Yeah their really nice. Yeah before he went hpf he was looking into cams, 2 of them were 2 grand, like the same material that are 300 dollar ones are made of. With most of the stuff its just cause its made for a "bmw".

My 650RWHP D1-SC setup is kind of new to me, and I have to admit that it seems a lot tamer than I thought it would. I mean, it's fun to drive, but it's just not the kick in the pants I thought it would be. I'm pretty sure this is primarily because the torque isn't that high. It's only 56xRWTQ vs. the 700RWTQ that would probably accompany a similar turbo setup. And, being a stick car, it does feel sluggish if you stab the gas at 3k RPMs with only 5psi of boost.

It's all relative, though. Two years ago my car would have scared me to death as it sits now. However, after a couple years racing dad's 9.5-second Nova, it's just... not the same, I guess.

Too many people over cam their Procharged street cars imo. I went from a fairly large cam to something almost as small as stock. I love the way it runs with a tiny cam. Power everywhere. Tons of tire roasting torque down low and I only lost about 5hp up top. 5psi @ 3000rpm will obliterate my 315's till redline.
