I used a throttle body as the BOV (or bypass, or recirculating valve). This one is only 58mm, not 65mm like I think it needs. And it should be mounted closer to the charge tubing.
Got in 3 test runs, blew out 3 different silicone couplers. lol
Made it to 10 psi on the last one. Acceleration from standing start was good, so the method seems to have potential. But abrupt deceleration has yet to be tested.
