Automatics lose a little more power by the time it gets to the wheels. . My 01 6 speed dyno'd stock 305/322 for what it's worth.

Auto's do dyno lower. My '02 with 4800mi dyno'd at 315.1 hp and 331.9 tq. From what I hear auto are suppose to have 5% more parasitic loss than 6 speeds. :cheers:

Put my 02 , A4 with 2,400 miles on the dyno last weekend. Got 290 HP and 311 TQ. See sig for mods. Just seems low to me. What do you think?

Re: 02 Dyno #'s (RDVT4ME)
What are your air/fuel ratios? Those #'s seem low. Are those corected SAE #'s?
Just curious cuz a lot fo the F-bodies around here dyno between 290-310rwhp. I dyno'd mine with just a lid and free mods and got 319rwhp.
I wonder if it has anything to do with having those big 18's in the rear.

I don't think they seem to low. I just dynoed my 97 A4 (blackwing,TPIS,Stinger,LS1 EDIT tuning) on a "mustang dyno" and it only laid 302 HP and 329 ft TQ at the rears. It has a 2:73 rear in it :cry.

My brand new 2002 A4 (Vortex Rammer is my only Mod) dyno'ed at 300 RWHP/312 RWTQ. This is about what I was expecting, because you "lose" 15% from the flywheel to the rear wheels.
But, on all 3 runs, my print-out showed a 50-60 HP drop-off between 5,800 and 6,200 RPM's. My Chevy dealership checked with Detroit to see if there was a PCM update, but they didn't have anything.
I am going to digitize and post my dyno reports, but has anyone else seen anything like this?
Mike :cheers:

For those of you who posted your Dyno #'s, what kind of dyno were you on? Dynojet or Mustang? i've been told that dynojet is going to give bigger Numbers......

Re: 02 Dyno #'s (Anth)
I could be very wrong, but I thought that dyno jet showed more HP because the mustang dyno replicated the actual "road load".

Re: 02 Dyno #'s (Ryan2002C5)
From what I understand, it is generally accepted that there is approximately a 20% drivetrain loss for automatics and 15% loss for manuals, and a little less for a powertrain with a transverse layout (most FWD or mid-engine like MR2/NSX - no loss at differential). With a 20% loss, 290HP = 362HP.
And I have to agree, DynoJet is the standard.

Your numbers are realistic, I'm skeptical of many of the dyno numbers posted on this and other forums. My 01 Z06 with a Vortex and TPIS long tube headers dynoed at 337 SAE on one dyno and 345 on another a week later.
