bypass/blow off valve question

it has to be mounted bewteen the tb and the supercharger. Also, don't just let it vent to the atmosphere or else the car won't run right between shifts unless you have a blow through MAF. If you have a draw through, you have to route BOV back into the intake tract.

You can just t-off any vacuum line in the engine bay and run it to the BOV or you can connect the line to the vacuum tree on the passenger side to one of the empty spots. Just to clarify, is your MAF between the blower and tb or before the blower in the fenderwell or around there? I'm assuming that its before the blower. If so, route some tubing to go from the BOV into the intake tube before the blower, not between the blower and tb. It should go air filter/MAF --->intake tube with BOV tube going into that--->supercharger---> discharge tube---> then throttle body.
