Congratulations Marty.

Very nice broad curve from PSI's package. I guess Kevin's question is due to the rather low torque at low RPMs?
I believe up to 480-490 FWhp are possible with stock K16s (25lbs) on a 996TT with stock heads and cams, they will be at their limit though and will generate excessive heat in long runs, if any, it might pull fast at the lower RPMs and loose some vs. larger turbos at high RPMs.
Other than the most important seat dyno test mentioned , It would be interesting to see some acceleration numbers vs. GIAC stage 2 K16 ZC.

JEAN, I agree with your asessment. This is crankshaft horsepower and the MAHA dyno calculates
it for you at the crank. I would love to run agains GIAC stage two and will if anyone in the area
wants to, I know the place...

Update on running condition: Neil Orton was right, my old plugs were junk!!
(I kept them and may post pictures later if of interest)
With new "stock" Beru plugs (#6), it pulls and runs perfectly,
no more misses!! The first thing the tech who drove it noticed was
how much torque it had early (Dave @ Auto Edge), it will pull 1.0 bar
before 4000 rpm and peak at 1.1 bar. Runs like a dream,
time to chase CGT's and Gallardos tomorrow in Wisconsin

Stock 996 TT Peak Torque = 560Nm at 2700 rpm

Cargraphic / RS Tuning 996 TT Kit 1 :
Peak Torque = 730 Nm at 4080 rpm
Peak H.P. = 485 H.P. at 6070 rpm

Sportec 996 TT Kit 1 :
Peak Torque = 650 Nm at 2800 rpm
Peak H.P. = 480 H.P. at 6200 rpm

 

Here is another for comparison from the FVD website (FVD supposedly utilizes RS Tuning programming):

FVD - Stage 1= ECU & Air Filter

Max Power: 360kW (490HP) @ 6000 RPM
Max Torque: 735Nm @ 4000 RPM
Max Speed: 318 km/h
Max RPM: 7000
0-100 km/h: 3.9 sec

FVD - Stage 2 = ECU & Air Filter & Sport Exhaust

Max Power: 375kW (510HP) @ 6000 RPM
Max Torque: 745Nm @ 4500 RPM
Max Speed: 328 km/h
Max RPM: 7000
0-100 km/h: 3.8 sec

 

What kind of correction factor does the MAHA dyno use?

 

Another data point - EVO's GIAC Stage 2 makes 440 RWHP at 6400 rpm, and 445 lb-ft of torque (at the rear wheels) at 3900 rpm.

Using a 15% drive train loss, that's 505 hp and 511 lb-ft of torque at the flywheel.

 

Dock,
I am not sure you can compare these runs on the MAHA to the GIAC RWHP numbers. I don't know what the conversion factors are. That is why the best bench is an acceleration run.
I don't think this car will pull stronger than the FVD or Cargraphic though.

 

The PSI 480 H.P. chip is $ 4000.00

 

I agree - just thought it would be interesting to know the MAHA's conversion factor.

 

$4k

Damn, I'm never going to get to mod city.

Thanks Marc

 

Sweet mother!!!! That's insane!!! My Upsolute chip yeilds similar results, and it only cost $700!

 

That price buys only the software ?

 

Not similar results , the Upsolute has higher H.P. and Torque .

PSI :
Peak Torque = 639 Nm
Peak H.P. = 486 H.P.

Upsolute :
Peak Torque = 660 Nm
Peak H.P. = 510 H.P.

 

There is no conversion factor with the MAHA dyno.
It measures the transaxle losses on deceleration !

 

Only software as with the Upsolute.
