Do you guys hear your bypass valve release air when your tranny shifts? It doesnt seem like they should since the throttle body valve is still wide open (even if the load is taken off the motor for a split second). However, I keep hearing what sounds like a "whoosing" air sound as I climb past 5500 RPM's or so. And it seems to make it as the RPM's are still climbing but its damn close to right before my tranny shifts.
It may be a slipping belt but I tightened it up the other day and while the "whoosing" sound did seem to get better its still doing it and the belt is really tight. I'm not running a super small blower pulley or anything (stock size on a Novi 1000) and I even have an 8" crank pulley, which should reduce belt slip even more.
I see about 10 lbs of boost max but when I hear this sound I can also see my boost drop to about 8 lbs. So I was also wondering if when your tranny (auto) shifts do you normally see a boost loss of a couple pounds or should it stay pretty much pegged? B/c either my belt is slipping or something is wrong with my brand new Bosch bypass valve. Thanks for any input, Ryan
