Dynamometer Results & Comparisons - Bolt-On A4 Dyno numbers (seem high)

So I recently dynoed my '99 Trans Am and it put down 350hp and 355tq untuned on a dyno dynamics. All I have done is QTP Headers bolted directly to dumped Moroso Spiralflows, Volant Cold Air Intake sealed to de-baffled WS6 Hood, LS6 Manifold, and Ported TB. I think these numbers are high for being untuned. What do you guys think? Ill try to post the graph later tonight. Any input would help. Thanks.

I'm saying yes that these numbers are too high. But what you need to understand first is that a dyno program can produce any reading if the setting aren't entered accurately (Density altitude). For a comparison when my 02 Z28 with LTs, Cat-Back, Lid, and TB had 700 miles on it it made 332whp and 336wtq and the car is an A4 with a 3400 stall.
You're not alone though, a few years ago I went to a dyno day where a guy with a 00' FireHawk with cat-back, lid, and MAF dynoed 380whp. Now most anyone who knows LS motors knows this is not even close to being correct. The guy was in our car club and argued that the numbers were correct since he had a print out.
I for my purpose only use a dyno as a means of tuning and take the HP and TQ numbers very lighly. When you go to the track compare your results from before and after you changed setups, if you gained MPH then you gained HP and as we know racing isn't done on a dyno.

I put down 33x rwhp and 340 rwtq with the mods in my signature with somewhat of a tune. I think some motors will just run better, I know it sounds stupid... but if some cars are lemons, then some have to be lemonade!

Numbers look high to me. Like they said, the real way to use them is to see and maximize gains from new mods and tuning and then test it out at the track. Obviuosly if you show a 50 rwhp gain on the dyno and then run the same mph then something's up.

My car with 1 3/4 LTs, O/R Y, Cb , Electric Cutout, SLP lid, FTRA, LS6 Intake untuned made 332hp....
I would say your numbers are high....even tuned I don't think I would hit 350 hp

I think its a little high. My car put down 344/360 with mods in sig.

sounds about right. what mode was the dyno in where you runned it? Shoot out mode increases power at the flip of a switch

It was on a Dyno Dynamics at a dyno day. Here are some other numbers for the day if that helps.
'03 LS3 Vette (stock) 405hp and 400tq
'07 Z06 (stock) 441hp and 430tq
Twin Turbo '03 Z06 688ho abd 670tq
When I was stock i was running 13.4s at about 103. After I did everything I ran 12.8s at around 109 bouncing off the rev limiter in second. Cause of my exhaust setup I have no low end but all top end. Hope this helps.
