and the magic # is....<drumroll>
2002 A4 1.8T FWD 5M
Stock HP: 143.7 @ 6000
Stock TQ: 141.6 @ 4350
Chip HP: 160.0 @ 6000
Chip TQ: 169.6 @ 3000
(GIAC 1.0 bar, TT 710N DV)
K04 HP: 198.2 @ 4500
K04 TQ: 236.8 @ 3250
(Neuspeed s/w, 317cc injectors, Milltek exhaust)
% diffs:
Chip/K04 HP: 23.8
Chip/K04 TQ: 39.6
Stck/K04 HP: 34.1
Stck/K04 TQ: 67.2
All numbers are at the wheels, and are averaged from several dyno runs. Stock numbers are from 6/27/03 (pre-chip install). Chipped numbers are an average of dyno runs from 6/27/03 and 2/13/04. K04 numbers are from 10am today. All dyno runs performed on a Mustang dynamometer by Curry's Auto Service in Sterling, VA. Some of dyno graphs are in my picture poster. Numbers at the crank can be (very) roughly approximated by dividing by 0.85. (which happens to be ~233/279 for the K04)

Great numbers. Impressive to see the improvement from your stock numbers
For all the "limitations" that the KO4 has, I still think it is one of the better turbo upgrades. Bolt on, looks stock, and has been around for a while.
If I ever do it I am doing a regular KO4. Matt your car must be damn quick with that KO4.

Nice! As far as you know, they used the same fan on the same setting
blowing into the grill in front of the car?
Any guesstimate on ambient air temp differences that may affect the numbers?
Again, congratulations.

nice numbers, but why is the peak for the K04 at such a low RPM?
I would expect it at the same RPM as the K03 peak, or higher by a couple hundred RPMs. I wonder how much is software and fueling in the top end?
