The PCM has an Injector Flow Table that is vacuum referenced (0 kPa to 100kPa). At least on the GP, the manual regulator takes over once in boost (it increases fuel pressure 1psi for every pound of boost).
As far as the pulley speed of the supercharger, I just looked at
THIS site, and it shows the M90 maxxing out at 12000 rpm, I know for fact that we are spinning it at close to 14k now, and once we get the intercooler on, will spin it up to 17k.
Perhaps one of you could talk to Zooomer (owner) of ZZperformance.com and he could do some testing for you.
He's located in Grand Rapids, MI, and he and his crew have developed a supercharger tester.
He could find out at what speed its maxxed out.
As far as the 'too much heat' thing I keep reading about on here. It seems that one member says the outlet temp of the 62 is 185 deg.
Unless it has something to do w/ the alum heads / block, thats an awful low number.
Here is a
LINK to some testing they did with different intercoolers.
Dont mind the bickering, it gets quite childish over there a bit.
Here is the pic you cant see.
Notice they spun those up to 14k, to simulate 13lbs of boost (gp's only have 8 stock!)
