does the maf sensor go by the intake or before the supercharger by the air filter or does it even matter????

I have mine installed after the air filter and before the supercharger per Vortechs instructions

Preferably before the supercharger unless you have a blow off valve, you'll have better drivability that way.

Not to steal the thread, but better drivability with the bov or the other way..and define better drivability?

Turbulence tends to be the worst problem with it, people generally don't put enough straight pipe before the meter. Mass air meters require a straight flow through the whole tube which generally is harder to create on the pressure side.

Personally I haven't had many problems with them on any of my kits.

And running a bov after the meter will cause you to vent metered air during shift/decelerating conditions. It won't effect drivability when just cruising or when on the throttle. popit style bypass/bov's only open in overboost situations; they are not in an open while cruising/idle unlike roots bypass valves which are open any time the engine is not in boost to equalize pressure for a near non existent parasitic drag on the engine while cruising.

thanks guys. i'm going to have the maf sensor on the supercharger and next to that the filter. i'm not going to have complete cold air in the fender thing.
