You need the one sold specifically for supercharger use-the poppet type do not flow enough to be useful in a compressor bypass valve.
The one from the Mini Cooper S would work just fine:

You might look at the stock eaton blowers on Ford and GM stuff for your ideas on where and how to plumb it.
Ok GREAT :-) Thank you!! I'll head out to a pull your own part yard and c what I can find. Looks like may be able to fit a vacuum diaphragm to a TB and use.....maybe.....anyway thanks, oh I will b able to get vacuum when supercharger is bypassed right? Want to make sure I have brakes!! :-0!!
About the time I tell someone it's running good something screws up!! I pulled up to my house couple weeks ago and idle afr went down to 10.8. Tried messing with fueling and couldn't get it to raise so checked mechanicals and found fuel pump won't hold pressure and 2 injectors had a tiny drop of engine oil on them so I'm tearing down the top end again. I was gonna put new t-chain tensioner after the first new one broke the piston retainer pin inside the tensioner and the new harmonic balancer I modified for sc drive pulley. Gotta find a quality parts supplier !!!! And thermostat keeps engine at 173f, it's a 180. Oriellys part that's only 4 months old. Maybe the valve seals are what's messing with me, I fixed some exhaust seals awhile back, guess I should have checked the others closer!!!:-/
