Nuff said John....

Show me one BONE STOCK A4 FBody that is making that kind of power on 8 lbs of boost. Remember, bone stock A4, 8 lbs....

Kenny H

nope, you didn't. The graph is just BS. Its not your fault, your just going by what they show you.

I'm hoping it really does make this kind of power, I'll order one at once....

But Joel and I have been in the game for a long time. We have both seen countless numbers of cars throw down huge dyno numbers and then come back with 116 MPH trap speeds. Forgive me if I'm a bit on guard with something like this, I've just seen it all too many times before....

Let me be the enth person to call BS to this dyno graph.

There is no tune like a Photoshop Tune!

Hey I dont care what they say man...I beleave it's possible and that your car did indeed hit those numbers...


At my local tuners shop....The average LS1 dyno's 290-305 rwhp....

My a4 dynoed 299.....Higher than a lot of stock mn6's have dynoed at this shop...

This guy brought in a stock 2001 Z06 vette.....It dynoed 340 rwhp SAE corrected.....

I SH*T you not that he brought that same bone stock 2001 Z06 back to the shop a few days later with the only mod being an A and A procharger kit at 8 pounds of boost...

They stapped her on the dyno and made 535 rwhp on a completly stock car with the exception of the 8 pound procharger....

If I hadnt seen it with my own eyes I would never beleave it my self.....

Factoring in that he had 40-50 more rwhp than you bone stock...But you had 9 pounds of boost vrs his 8 pounds...

I have no problem beleaving that you got 490 rwhp.....

BUT TO BE HONEST I WOULD PUT A 6 POUND PULLY ON AND TAKE THE POWER DOWN TO 430-450 RWHP...

YOU'LL BARELY NOTICE THE POWER DIFFERANCE...BUT YOUR TRANNIE SURE WILL......

Its not possible,John just admitted this dyno reads HIHGER HIGHER than a dynojet..He's probably around 450RW which is believable,One things for sure I bet its a hoot to drive..

Go get those time slips...

I didn't say they were bone stock. I just said that F-Body guys have been getting 100-150HP from the Pro-Charger kits. 150 isn't that much of a stretch. The poster admits that the dyno he ran on reads high. So 150 wouldn't be that big of a stretch.

As far as how much boost the F-Body's LS1's can take or need to make that kind of power, I don't know. I've just seen people claim similar results off the Pro-Charger.

I never said the Dyno Dynamics dyno at ST-Performance reads HIGHER then a DynoJet. I said it was calibrated to DynoJet Specs.

I did say that ALL DynoJets read HIGHER then Mustang Dynos.

I pulled the dyno slips on the Dyno Dynamics dyno. If I was on a Mustang Dyno it WILL read lower.

To all who think I photoshop'd the dyno slips you can kiss my If you don't believe me call ST-Performance and see what they say. 912-925-2077

So many negative remarks. I don't get it. I would think more would be impressed than anything else and not throwing up the BS flag. Being skeptical is one thing, but being a dic* is another. Anyways, it made every bit of 490rwhp ACCORDING TO THE DYNO. Yes, I was there. For most of the day I might add. I work with John and have the pleasure of riding in the car pretty much every night when we take dinner at work. The fact that it reads lower than a mustang dyno, ok, whatever. We got that. That's not being disputed. I've been in the car stock all the way up until what it is now. And let me tell you, the difference is unreal. And picking up 115rwhp with just the TUNE makes it feel like a whole nother car...again! My last car was a 480whp Eclipse and I have no doubt it'd been a damn good race after riding in John's car post-tune. By seat-of-the-pants I have no doubt that he could trap 120+ in the 1/4 (traction's gonna be a bitc*). Hopefully he'll be able to make it somewhere soon to find out. But when you work all week and have a wife and two kids, not to mention tis' the season!, making it to the track to "prove" to everyone on here that he really is making the power his dyno sheets say he is may not be the most important thing to him at the moment.

All I'm saying is calibrated = horsemanure
Go put it on a dynojet and then we'll have the answer..I was giving u props John,I'm very impressed with your setup even if it is only making 450RW

Kenny H

Your A4 C5 dynoed 299 yet went 103 MPH? What was the DA? My GTO also went 103 MPH stock....but with a 400+ lbs weight disadvantage. I guess my GTO must make 330 RWHP on that dyno....

Kenny H

Fine lets give him 150 horsepower. With his 490 RWHP that means his stock A4 made 340 at the tires.

Why is this so hard for you guys to understand? The numbers do not add up.

You said FBody guys have been doing it for years. What exactly have they been doing for years? Has any stock FBody ever seen 200 RWHP from 8 lbs of boost through an A4? Answer the question.

Kenny H

I don't think you photoshopped anything, I just think the dyno either isn't accurate or the car is seeing more then 8 lbs of boost, or its not 100% stock. That is all.

Well, all opinions aside the whole point of this post was to show the gains from a pulley swap (7 psi to 9.2psi) and a good tune. I went from 375 rwhp to 490 rwhp and from 400 ftlb tq to 442 ftlb tq with just the pulley swap and a custom tune. This was on the same dyno of course which is what dynos are supposed to be used for, measuring gains.

I gained 115 rwhp/42 ftlb tq and it runs very strong. So strong in fact that I'm looking at better tires for the rear (all around most likely) to help with my lost traction.

Nickn20

couldnt help but notice this thread, with 8.5 psi you can expect to see a ~57% HP increase with the proper amount of timing and fuel of course, and then there are factors like not enough octane so you must reduce timing, id say this would put you in the mid 50s range, granted the average 04 A4 GTO I have dynoed on my dynojet at 290ish rwhp so at 52% gain this is about 440ish rwhp, now the 04 GTO already has a really low timing map from the factory, I would give this specific setup a 54% gain period, since the timing is damn near where it would be with the boost!, this puts the car at 446 rwhp. It looks to me that this dyno is severly off its calibration, or something else is missing from the equation. either way take it to the track and see what it runs, that is what really matters right? I also read that the intake temps are 30 degrees over ambient? IMO that is not quite what I expect from a good working air to air, I like to keep it around 10 over ambient, or I will start to look for other methods of cooling, like meth or more air to the intercooler. I didnt post this to join a pissing match, just some food for thought.

KennyH...

Yea my track is slow and the 2.73's dont help eighter...

Da is usualy around 2000 ft here in Oahu Hawaii at raceway park..

To give you an idea of how slow my track is...

The quickest bone stock record for a 2002 Z06 is only 12.7 at 111 mph...
The quickest bone stock record for a 2002 Viper is only 12.6 at 112 mph...
I usualy match or beat most 2002 Z06's at my track when there stock by just running 13.0's....

As you can see...Even with LS6 heads..A 224 cam and a Vararam intake Im still only trapping 107-109 mph at this slow track!!!!!!! And thats with 370 rwhp!!!!!!!

The 04 GTO's run around 14.0 over here with the 05 GTO's running 13.7...

Camaros all running around 13.7-13.8....

The other stock C5's are all around 13.6-13.7...

As far as I know my 13.5 bone stock is the quickest number for a stock C5..

Ive even had other C5 guys try to say Im lying about my times cas some of the other A4 2.73 guys only did 13.8 at 100 mph...

I just got lucky and got a strong one...( well strong by my tracks standards anyway)

Ha ha ha ha.....

Amen! Congrats!

Sheesh! Tough crowd...that said, those numbers do look a bit high given stock exhaust, etc. But enjoy it!

Sure enjoy my boosted LS2, that's for sure.

Not on 8lbs of boost. No. I was referring to the Pro-Charger itself. Obviously higher boost levels would be required. And yes, a stock bottom end won't last too long at higher boost levels.
