WS6 #3392

I was wondering if or who had some dyno sheets of the before and after they put on a ATI Procharger. If you wouldn't mind to share them. Just wondering how the gain was the entire curve.

I do not have my sheets, but I went from 300 rwhp to 518 rwhp with 11 psi and the mods in my sig.

Thanks Urban Legend. What I am wanting to see is what people are making under the curve. I am going to put a ATI on mine is why I am curious.

We will have before and after dyno graphs available in a few days on an '04 Corvette. Bob

Here is mine comparing stock VS 7.5-8psi run. Run were done on the same DynoJet.

Bob,
I would like to still see the graphic of the 04 Vette.


LSs1Power,
That is what I have been wanting to see. What the entire rpm band looked like. That is a nice increase under the curve. Thanks

WS6 #4541 Bob just finished my 04 vette. I have Kook's long tube headers and hi flow cats, corsa pacecar catback exhaust. Bob's guys put a Procharger on it, it looks great it's real clean looking. I gained 198hp at the rear wheel's .My stock numbers were with a blackwing airfilter and a predator programer. I had 260rwhp and 306 lbs of torque. After the procharger was installed, they had it as hi as 469rwhp but had to bring it down to 458 rwhp to keep it from knocking. I also got 440 lbs of torque. I almost spun it out when I nailed it the first time. I was driving along at 60 mph and nailed it and smoked the rear wheels for about 50 feet. It is unbeleivable, I can't get the smile off my face. It is a convertible and I really don't hear any noise until I get on it, and then it comes alive, and if you weren't sitting back in your seat when I hit it you are now. I think I will need new tires before June. Ha Ha

That is an awesome gains you got there. The more I read the more excited that I get to get back and put it on. If you get a chance could you post your dyno sheets of both runs? If you can't post it could you send it to me? Let me know and I will send you my email address. How much boost are you using with your setup? Thanks for sharing your info and numbers.

Rockitman

I'm running 8 psi of boost. I will post the sheet's but it will have to wait until Monday when I get to work and can scan them in.

WS6 #3392

Cool... Again great numbers. Do you plan on taking it to the track to see some 1/4 numbers?

Rockitman

I don't know yet. I would have to get some drag radials, and I'm 45 so my reaction time can't be good. But I might go to the track when some friends rent it, for a fun day.

Here are some pics.

Rocketman, I see you backed down to 458 rwhp due to knock, was there an issue with the fuel or what? Also did you use any type of cam with your set-up. I usually hear Bob, say that with a cam amd D-1 it's pretty easy to achieve 500 rwhp..Car looks great!!!!

I almost forgot to ask you what kind of gauges do you have on your a-pillar and what did you pay for them??? Thanks

my pretty much stock ls1 had 335rwhp/345rwtq....after the p1 install and hand held tune @ 5# it made 431rwhp/439rwtq....the stock numbers could have been a little higher since the car only went to 5500 and the sc installed went to 6200

Drewstein

I had 332rwhp before... There is no comparison "under the curve" since I pass my all motor peak number around 3K rpm now.

Rockitman

I want to run pump gas 93 oct. I don't want to add octane boost everytime I fill up.No cam yet I figure next I will have Bob at EPP take the motor to a 383 stroker with forged internals and turn up the boost. As far as the gauges go I don't know how much they were, ask Bob. I wanted them so I told him to add them.

Rockitman

I have been told that the dyno numbers are lower on a mustang chassis dyno. They are more real world. I have a local guy I'm going to take the car to and have him dyno it to see where it comes in at. I will let you know.

my dyno was SAE corrected at the dyno in portland maine F1 dyno....dunno what kind they have there, but it does do awd cars too
my most recent numbers were off a dynojet i believe at dez racing in Mass. but those numbers are also with 10-12#
