^^^sorry champ...didn't mean to!

JBimolaS4 dyno'd 416whp
http://www.youtube.com/watch?v=Fs8757iq6HE
then ran 12.95 (this was his best run)
http://www.youtube.com/watch?v=UHBXH4Bx-vU
ngng dyno'd 402whp in his B6 S4 with VF M90 SC kit (and RS4 body kit)
http://www.youtube.com/watch?v=HtAdpjIgHKU
...but could barey pull 1/2 a car on a 320whp all motor S4 that had the same mod list MINUS the supercharger. They dyno'd on the SAME DYNO, SAME WEEK. 034 Motorsports' dyno. Fully independant. Interestingly when the all motor car turned on the nitrous on the dyno, it hit 400whp. When it turns it on in the race, it puts a buslength on the '402 whp' supercharged car. Love this video...JHM makes good ones.

first few runs were all motor black car vs. supercharged yellow car
last 2 runs the black car turned on a 70 shot of nitrous
they explain each run with text right before each one

Oh, ok.. I kinda started skipped through when it black car kept winning. That's a crappy SC.

The compressor map shows it will max out at around 700CFM...and net of 30hp to run it, that means it will generate about 425hp crank, MAX. Unfortunately for VF and PES full bolt on cars make just about the same! The M90 gives a good bump over stock...but it's ceraainly not worth $10,000 when you can accomplish the same gains with intake manifold/full exhaust/tune.
You guys ever read a TVS 1320 compressor map to get an idea of the absolute MAX CFM it can flow on your car?

Yea, but you can see where near 18,000 RPM (where this spins near our redline) it's getting way out of the efficiency range, hence the lack of much more power, just a slow gentle climb to near 13PSI max at redline even with the SC flap closed.
Will be interesting to see:
1) what the final RPM speed for the SC on the APR and GMG pulley swaps become.
2) What spinning it faster sooner will do to keep the SC ahead of the engine's thirst for more air and potentially increasing overall boost across the entire range.
