Nice:laugh:

Someone needs to try a cougar call, though. Do they make those?

I've never understood the fascination with that Psssh sound that aftermarket blow off valves make. Most of them just create a lean condition because the cars they are installed in came with a bypass valve stock so instead of recirculating the excess pressure back into the system the blow off valve sends it out in the atmosphere with a noisy pssh while the engine management system is really expecting that pressurized air to return back into the induction system.

Hell, I've spent years watching 900hp turbocharged open wheel racing cars and never heard that stupid psssh sound once. Don't even try to tell me that it has anything at all to do with performance.

That's because they don't waste it.

Wouldn't that create a rich condition? I am unfamiliar with the specifics of connecting a BOV, since I have only owned NA, but it seems to me that if they are ejecting metered air, the EMS will inject more fuel than needed, whereas if they are ejecting unmetered air, it wouldn't matter because the engine will only inject enough fuel for the air that made it past the meter.

The problem is, when you get in higher boost ranges, a recirculation valve would not be able to release the pressure fast enough after the throttle body snaps closed. The resulting boost spike could damage the compressor wheel, or even the throttle body itself.

BOV is supposed to be after the intercooler and before the MAF.
