Rod Millen Motorsport Supercharger - Dyno Results
Before I begin, I want to thank Pete over at WORKS for the tuning he did on my RMM Supercharger utilizing an E-manage Piggyback
Works does race car fab and preparation and is located at Infineon Raceway, in Sonoma CA.
They also have a dyno and tuning facility located in San Rafael, where I took my car.

If this name sounds familiar it's probably because WORKS is best known for their Tuning of Mitsubishi EVO's.
It's a long story, but I was lucky that Pete was even interested in tuning my GS. In short, he is a true gear head and passionate about what he does. He looked at the GS as an interesting challenge and he did not dissappoint me with his results.
Dynapack Dyno Specifications
398.6 wHorsepower
346.9 wTorque
VORTECH V2-SQ Supercharger @ 5.7 PSI Boost !!!
Estimated power at the Crank @ 20% drivetrain loss is 497 Horsepower

I was a bit disappointed that I didn't break the 400 HP barrier, but atleast I know it is within reach.
I was surprised at how low my boost was, but one can only imagine how much more power I can pull when I bump it up.
Also note that Pete did a conservative tune as I told him that I wanted driveability versus trying to hit big HP #s.
I got what I asked for, as the car pulls hard at any speed and any gear and never seems to run out of steam. A couple times I went WOT at about 70 mph and the car just pushed me in my seat all the way to about 120mph and around that point the tranny shifted into 5th gear and proceeded to let up on the throttle quickly, as I found myself approaching cars at a high rate of closure.
There is definitely room for a more aggressive tune as the car is not even running lean. Also we accidentally programmed the wrong OEM injector values, making the E-manage calculate the wrong Delta between the stock and upgraded injector values. This explains the slightly rich condition.
So question for those in the know.
The Dynapack dynamometer they used is a direct axle connection where the rear wheels are removed and connected directly.
What kind of HP / TQ numbers can I expect using a DynoJet i.e a roller type of dynamometer? More / Less / Same?

I don't have the air fuel numbers at hand. I actually did two dyno runs back to back within 24 hours. Went on to the Valvoline dyno at the Nightshift meet. The second dyno was where they told me I was running a tad rich.
Need to download the files soon and report.
While you FLA & TX guys are just getting up, I need to sleep at the moment.
Later guys.

I got to drive Glen's newfound beast a few weekends ago when I was in NorCal. I've had a chance to drive it untuned and now tuned. Let me tell you, acceleration is nuts. There is so much power, VSC kicks in just from straight line acceleration...and just on a damn freeway on ramp! There is so much power, his already wide and sticky Michelin PS2's lose traction like it's nothing. Power from a standstill and power on the freeway is plentiful. I can tell you all that I never floored it, only gave it half gas and the car wants to keep going and going. I can only imagine what it's like if I put the pedal to the metal. I was too scared to lose traction and spin the car out into an unintentional drift.

There are some issues with the timing control on the Ultimate. I've talked to Greddy so many times about this problem. There are some bugs with the software also. I had the ultimate for 3 months and decided to ditch it. If your guy have time to mess with it, It would be a great piggy back.
