Ruf Kompressor update
Well, we just got back from a 1000 mile road trip with the 997 we
just installed the new Ruf Kompressor on. We averaged 23mpg while driving the car hard a lot. It ran perfect. No problems at all.
We drove to Lubbock, Texas where the altitude is 3400 feet and the best fuel we could get was 90 octane. The motor performed flawlessly. No hesitation. No pinging. Even at that altitude we still
got wheelspin at will in first gear, and sometimes in second. Of course we turn off the PSM everytime we start the car. Its more fun that way!!!!! We cruised at 130-135mph for several miles at a time on some of the back roads we drove on. But then we had an encounter with a state trooper. Luckily he did not have his radar on. We topped a small hill and he was doing a u-turn in front of us. Found out that the brakes also work very well. The trooper followed us for a little ways before he pulled over one of our friends in his Boxster for not having a front license plate. After that we drove a little slower.
If anyone is in Dallas and wants to test drive the car, please feel free to do so.
Also, if anyone close to us has a Porsche with the EVO supercharger, we would like to do some side by side tests.

Mr RUF tech,
I only have two questions sir...
#1) What exactly is the effective compression ratio of the motor with your kits' Head Gasket installed. (we heard 9.7-to-1 from other but wanted it from a RUF tech himself*)
#2) How much boost exactly are you running with this kit? ( In both BAR & PSI measurments )
...thanks!
---Kevin D.
PS: If you could also post the actual dyno chart (with torque curve) of your recent dyno it would be fantastic!
(hey, its worth a shot asking!) I'm become more and more interested in this kit despite the steep price...just need the raw numbers. Really clean kit guys.

And 0.6 BAR = 8.82 psi

...And so the effective compression ratio AFTER your gasket is in fact 9.7-to-1 ?

can you please post the dyno runs. 
if not then can you do some timed runs? 0-60, 0-100, 60-130, 1/4 mile, trap speeds.... something.... anything. i'll try to do the same but it's hard to find a flat stretch of road in the bay area, all hills and twisties.
