ATI Procharger @ 8 lbs. What kind of numbers (ET/trap/dyno) would I see with an ATI Procharger w/ 8# pulley? My current set-up and 1/4 mile times are in my sig.
Also, with a proper tune will 8 lbs. harm the LS1 in the long run? Thank you so much.

Numbers in Sig.... Didnt get a clean run at the track because clutch started slipping, but it traped 124mph with 2.4 60ft not from wheel spining(Clutch slipping).... Have a new clutch in and going to try soon.

Pretty good, but is this trap with the cam?
I can give u a better estimate next time i run the car with the new clutch. Most likely im going to use ET streets this time around.

Thanks, but you're going to have to subtract how much the cam adds because I don't have a cam. Good luck.

I have the D1 and a FM7 cam also , no track times yet but dyno #'s in sig. with 9# at 5800 . Too much boost , I'm ready to pulley it down some so I can raise the rpm's some , Good luck
I have the D1 kit on my GTO with a cam also. 551rwhp 457trq at 7k rpms and 8.5psi. I am going to teh track tomorrow night so we will see how it does, but my car also weighs a lot more than an FBody.

On my Mustang Chassis Dyno, most F Body's that have just headers and a cat back typically dyno in the 310 rwhp range, as an average. Adding an ATI ProCharger D-1SC at 8 psi of boost will bump up the rwhp into the 440 to 450 rwhp range.
With proper tuning and with the air/fuel ratio in the 11.7 to 12.0 range at wide open throttle, and with 42 lb fuel injectors and a higher capacity in tank fuel pump, you will end up with a very durable and dependable combination that still gets good gas mileage. Driveability with these combinations is excellent!
We just installed and tuned a one owner '94 Corvette LT1 car this week that we installed an ATI ProCharger D-1SC on. Amazingly this Corvette has 192,000 miles on the internally untouched original engine! The owner realizes that he is putting the cart before the horse with adding the ProCharger, but said he'll just have us rebuild the engine if it goes... Bob

If I'm already at almost 350 rwhp, can I expect to be around 480-490 rwhp? And is this with a tune or without a tune?
Thanks,
Phil

the problem is from what I understand that you can only go so far on the stock heads/cam before detonation and knock start coming into play.
if you upgrade aftercoolers im sure that would be no problem, but EPP is right, average is anywhere from 430-460 possibly rwhp on stock motor with minor bolt ons.

I'm assuming your numbers were achieved on a DynoJet, which does not apply a load against the cars drivetrain like a Mustang Chassis Dyno does. On a DynoJet chassis dyno you would indeed be up in the 480 to 490 rwhp range.
These numbers certainly are with a tune. You would never want to go wide open after adding a supercharger without some sort of tune! The fuel ratio needs to be richened up to keep the pistons from self destructing. Even one or two wide open runs without a tune can be potentially fatal to the engines longetivity. A mail order tune is better than no tune at all, but does not compare to getting a tune done on a eddy current chassis dyno with a wide ban air/fuel ratio meter. Bob

Bob...when did they start making Eddy Current dyno's? Can it scan for cracks in rims too <NDI/Eddy Current joke>
