I am running an ATI Procharger D1SC in my 95 Z28 in my sig. Below are some pics (you can't really see it under the hood as they sit really low) and some video's of my car so you get an idea of how it sounds/runs.

are you running the twin intercoolers? i was thinking of running a vortech t trim so that i dont have to cut away the cover for a front mount intercooler with the procharger setup(f1) i was going to go with.
The twin high flow intercoolers will only support about 8-9#'s of boost before they just can't keep up with cooling the IAT's that the boost does.
I am running a FMIC (front mount intercooler). Most people hack up thier front end to get maximum air flow, but it is not needed. I just cut out the areas behind my fog lights and created an air dam under the bumper that directs air up to the FMIC, and my IAT's are nice and cool. I am running 15#'s of boost, and could probably hand 20 if I wanted to.
Methanol injection can also help cool IAT's and keep you away from detonation. It also is a great alternative to running race gas as it costs you a fraction of the amount that filling your tank with race gas would cost, and it does the same thing.
The Vortec "aftercooler" works well, and also would help you retain your front bumper in its current condition. I would reccomend going with a T-Trim if you go with a Vortec. It will make similar boost as my D1SC does, and it will wine about the same.

you gotta pic of the front of your car. so i can see how your intercooler is mounted? i was thinking that if i ran a procharger with a fmic that i would cut the whole black center out for it and then mount a black mesh grill from a non sponser so that the black piece missing wont be as noticable. also can i run like 15 pounds of boost with a t trim or with the d1sc?
Here's a few pics of the FMIC install, to what my car currently looks like. From the final pic you can see (barely) that the areas behind my fog lights have been cut out. And you can see the air dam just below my front bumper that helps direct air to the FMIC. Don't get me wrong, the most air flow to the FMIC will be had by cutting a huge gaping hole in your front bumper, but I am telling you it is not necisary and that by mimicking my car, you can still have the intercooler get enough air flow to help cool your IAT's. Running intercoolers will probably drop the potential boost you car would otherwise make without them, but then again they are pretty much required to keep your IAT's cool to keep you away from detonation.
Yes, the T-Trim, and or D1SC can easily support 15#'s of boost. Thats what I am making with mine, and honestly if I had a different heads and cam combo, my D1SC would probably be putting out more. I have seen tons of people making 18#'s of boost with their T-Trims and D1SC's. Some people claim to have made 20#'s before, but I have yet to personally seen it done.

what kind of cutting did you have to do to make it fit? my motor is going to be a 408 or 427(undecided) with all forged internals going into a built 6 speed, built rear end and suspension, and a nasty performance fuel system.

Sounds like you've got the right idea to get it done correctly. Specifically to get the FMIC to fit, you'll just need to remove the foam insert in the bumper out. To my knowledge there isn't really anything else you'll need to do to make it fit. For the best price (and to my knowledge the ONLY company making FMIC's for our cars) call Bob at EPP (www.exoticperformanceplus.com). He can also help you with further install info as he installed mine.

I have the ProCharger D-1SC as well 383, twin high flow's. My car did 542 rwhp and 524 rwtq but @ only 5800 rpm I ran into rpm issues (blowing out spark). at that rpm I was only making 12 psi as well. This winter I do plan on putting water meth on it as well as a smaller pulley, and fixing my spark issues and shooting for somewhere really close to or maybe bit higher than CALL911's number's. in my opinion I would go ProCharger ALL THE WAY. without a problem.
That I don't know for sure. Call Bob, he would know for sure on that one.
Check your spark plug gap. Originally mine was blowing out spark as well. Then we re-gapped the plugs for .032 and havent had issues since. My AFR 180's although fully ported by TPIS, still don't flow as good as a set of 220's would or something else of that size. Most people see a few more pounds of boost than I do when maxing out the D1SC (usually around 18#'s). More power is definatly doable.

yeah it looks like he cut it out. im almost 100% positive on it because i think i can see it laying on the floor in the pic that shows the intercooler mounted without the cover on. thats probablly what i would have to do to get it to fit. i think i might go with the procharged f1 setup from exotic performance plus or do you guys think i should go with the d1sc.
I'm running a Vortech T-Trim at 16 lbs. Car currently makes 550 rwhp. With a smaller pulley setup, car put down 597 at about 18-19 lbs of boost. The blower whine is super loud.

Yeah I'm running the NGK TR6's at .028. I'm still at all stock ignition as of right now. I am still running stock heads, they are ported pretty well though.
and swapped to 2.02 1.60's. and stock unported intake. after I get all of the bugs out i am going to throw some 114 in it and tune it with that and hopefully get into the 700's or close to it.

Im running a P1SC procharger at 9.5 psi
with just the boost, freed up exhaust, new gear and rear end (alot of bad things heard about stock ten bolts snapping and twisting with anything above 400 horses) and a mild cam i made a little over 500 horses at the wheels. and thats with the stock heads.
