Procharger MAF location question
Hey everyone,
Hopefully a simple question here. I've tried searching but came up empty-handed.
The car in question is my dad's '95 LT1 with a Procharger (about 5 yrs old but he's probably only put ~5000 miles on it, if that). When he initially installed it, the MAF was relocated to the area in front of the passenger side front wheel. It's always had an issue where it will die at idle, after idling for ~30 seconds. Just this week I've determined that the Bypass/Blowoff (whatever term you want to use for it) Valve isn't flowing enough air, thus causing a lean condition and stalling the motor.
I come from the DSM world and am very knowledged in turbos. A lot of DSM'ers use a GM MAF in a blow-through setup. Is this MAF capable of being moved to directly before the intake manifold without any changes? I don't see why not, but I wanted to doublecheck first. I've seen a bunch of other Procharger installations that have the MAF located there.
Also, has anyone else had the same problem of the bypass valve not flowing enough? It's obviously a really crappy plastic Bosch valve that will be replaced with a higher-quality unit, vented to the atmosphere, once I determine that the MAF can be relocated.
Thanks in advance,

There have been a few conversations about this... really it doesnt matter where it is located as long as it is not too close too a turburbulant area . I have a vortech i have mine directly behind the air filter and have to run a bypass system as you described to meter the air to keep the fuel trims in proper perspective, yes you could also mount it to the intake air side and thus eliminate the bypass plumbing.
hope this helps ...

Just a follow-up...
The MAF was moved to just before the TB and the stalling problem is gone. Going to put in an aftermarket BOV to ensure we're not loosing boost through the crappy Bosch unit.
Thanks for the suggestions guys.
