Whats the best position for the by-pass valve? right before the throttle body or closer to to the IC or right after the supercharger discharge?

I'm guessing because you're calling it a BPV that you're running a draw-through setup? You are going to want to put it after the intercooler for simplicity, in the piping to the tb.

Here is a picture of where mine is. The important part is to have it angled away from the meter when it re-enters the intake pipe.

Well, I am not running anything yet, but I have a mongoose kit and a paxton intercooler. So yes I will be running a draw through setup. I had just been wondering if it made any diference where the bpv was mounted. there is quite a way from discharge to throttlebody and many places it could be mounted.

The procharger setups put them right after the blower, before the intercooler and plumb it into the intake tube with a reinforced flex hose setup. I don't know how much a difference it makes as long as it's not flowing back into the maf.

That's where mine is placed

I think there is 2 factors to consider. 1 is not to have air pushed back into the supercharger and the other is to not let the recirculated air being pushed out through the intake and maf. man I bought a **** load of stuff I dont know how to install. lol its good winter is long this year :-)

Right after the blower is where mine was set up and is where Procharger designs their units. It makes sense to me that the closer it is mounted to the discharge tube of the head unit, the faster the pressure is relieved from the blower itself. The goal of a BOV or BPV is to relieve pressure on the blower itself. It seems like there would still be some pressure being produced by the blower if the BPV was mounted after the intercooler.
