bov/maf

[blitz27t]

what type of bov would be ok with maf sensor on a SR20det rwd? Would the greddy type s bov have a return valve for the maf and still have bov sound? Thanks in advance...

when you recirc any BOV, the sound is MUCH less. I can still hear mine a bit, but it was more than 10x louder with it vented to the air.

I posted a how-to about it.

It also depends on what type of air filter you're using. An open element filter is going to give you more volume on the BOV than a stock airbox would.

yes, and i have an open element filter, and it's still not loud. i *can* hear the turbo spool more now at part throttle because the valve is recirculating the air (what would be a leak if there wasn't a hose routing it back).
