Well To start i put down 387 Hp 360 tq.. 2002 z28. ASP pulley, ported tb, yank ss4000, slp lid, hooker long tubes through a 4" mufflex/spintec single exit. Im going to true duals all the way to the back and then getting it re dynode. I was told by many that the 4" is a power robber especially that spintec muff. My buddy took his 4" and swapped for an x pipe setup and put down another 26whp. I was there so no exaggeration i even helped install the x pipe on the dyno. Car feels phenomenal on the street. But i was wondering do u guys think this power is normal considering people with smaller cams are putting down more power. I know bigger isnt always better but i was hoping for atleast 400whp. I heard this cam likes to be dumped out the headers so thats why my power might be low. I know the tune is perfect Speed inc. invested a good amount of time in the car. But im just kinda sad ya know!

The dyno numbers don't mean everything man, don't be down about it!

Thats what a lot of people are telling me. I guess i just need to wait for a good track day to see what my car really has. It just kinda sucks you see so many people with around the same setup putting down 413 and that. I guess my mood is down cuz its april here in chicago and were still getting snow. it literally just hailed for 5 minutes, 20 minutes ago. This area sucks!

Why do people say this? Yes it matters, its like saying you have a UGLY *** girlfriend, but she ***** good. If you pay for a certain range of numbers/times your expecting and you only get 1/2 of what you wanted, then it isn't OKAY. Sure track times are the main thing, but a piece of paper with numbers on it is way more than just a piece of paper, its bragging rights and being proud of what you put together.

autos arent really big on dyno numbers!! then again you are running a 4k stall which is eating alot of dyno hp numbers. but as long as you know its a beast is all that matters.

A4 with a 4000,stall,especially if it was unlocked,won't dyno near as high as the same combo with an M6...

Im pretty sure it was locked. going through a stock 10 bolt 3.23. im kinda hoping the true dual puts me over 400. or is that too much to ask u guys think?

I hate to guess at dyno #'s but if it was me i would try a fast 92/90 then work back to the exhaust.
Those are not really bad #'s with that big of a stall.
Good luck on your combo.

Those are some good numbers, but having a stalled A4 will definitelty keep the numbers lower, and yes they tune it locked. Your exhaust might be holding back some power, and if you have the money switching to a 90/90 set up will gain some power as well.

First of all you don't need a 4" exhaust. Maybe with a stroker motor and a supercharger yes. It will hurt you more. If you want true duals get a nice 3" setup with a x-pipe.
Speed has a dynojet dyno. With those numbers as far as I am concerned those are damn low for a big cam. my buddy with a G5x3 cam put down over 400rwhp on the same dyno, M6. The auto does hurt it to a certain point. My other friend with a TR224/224 cam and 3600 stall put down a little over 380rwhp on that dyno. Every car is different.

I say keep the exhaust you have on it, put on some electric cutouts for the track. Invest in a Fast 90/90 setup and get it some heads. I believe that the stock heads with that cam is holding alot of power back. Take the car to the track and see what mph pulls.

A4 + big stall = low dyno numbers. Lots of people have already posted this. I have to agree. Get your true duals and go back. I'm sure you'll be doing better if the motor can exhale better. What intake are you using ?? A ported 90 or even the 92 would help out quite a bit.

With that being said, big stall + auto = nice track times. I guess its all how you look at it.

i wouldnt say it the 4in exhaust hurting you, i would say its the muffler, i would put a magnaflow 4in race series and see if it picks up power........ but there is alot of guys making big power through 4in exhaust

Dang if you don't sound just like my wife when her stalled A4 H/C/I/E car only did 441rwhp! Shoot, it is still a sore point for her even if her car is running well at the track on a 150 shot.

I know she is going to want more out of her new LSX motor when it gets here too; but I am sure she will be happy with the track times...

Ironically her car did 385/386 cam-only (no UD pulley, LS6 intake/PP TB) with a MTI X1...
