Looking to see if any clever Volvo people out there have make a trick aftermarket BOV that recirculates back to the intake, stealthiness is a plus.
Problem I'm having : My Kinugawa BOV (vent to atmosphere) is tight and working great, but the fireballs exiting my exhaust with WOT throttle lift off is bound to get me in trouble. I had a IPD HD compressor bypass valve ( cbv ) around to try out, and the surging/stalling is horrible on my setup.
