We usually do coast down testing on the first 5-10 cars we tune to get a good delta. Keep in mind that we've dyno'd 996tt's with less then 5000 miles on them... Taking these results and working backward with stock flywheel hp is a fairly good indication of drive traintrain losses as long as the factory was accurate with their ratings.
That is my point on the whole debate.
Take a stock car, see what it loses from stock fw rating to whp, and then add that figure back to the modded whp results.
I do believe that using a flat % is flawed as mods are added, because it will inflate the total loss and therefore give inflated fw estimates.
I'm curious, what does a stock 996tt make at the wheels on your dyno?
Thanks.

Cool, I'm likely going with Tial Alpha 3076's on my 2005 996 TSCab Protomotive 4.2L conversion this summer-shooting for well north of 800HP to the crank on pump.

Nice results! Congrats!
Tony just did my car....Thanks again Tony!!!
@ AMS w/ similar mods & 3071's- my car made 578 FT/LB's wonder how that compares to Tony's dyno
Hopefully some 60-130's & trap speeds are coming soon? Excited to see the results!!!

have put about 800 miles on the car...the thing is out of control....just a complete animal all over the place....virtually no loss in driveability...the clutch is on the heavier side but thats about it....the thing is scary fast....thnx again tony!

Spot on... good math skillzz 
. 589 I believe was the high pull with 600+ ftlbs.
I know there has been discussion lately what the limit of the stock fuel pump is.... This is 100% the limit of a good working stock fuel pump.
Specs
Alpha 3076's with billet wheels (1.3 bar)
93 oct pump fuel... NO METH
USP Inlets (very nice piece!)
Europipe exhaust
72lb injectors
Custom EPL Tune
AWE IC's and silicone hoses
Ill post some dyno plots shortly.

What were the air temps when you were dynoing??When Tony was connected to my car at Kelly Moss on their dyno,,Tony said I ran out of fuel and needed another fuel pump..Dyno room air temps were in low 50s then...As. I started a thread after that......I thought those 3076/billet Turbos flow alot more air then my K24/18gs??? Plus you made more HP+ TQ on the stock pump only...So, I am trying to get a handle on this because I am going back to Kelly Moss to have that done tomorrow....
......Thanks
