Nissan 370Z Forum - View Single Post - Noob here with some questions. (Wastegate, Blow off)

A couple of points: Both the BOV and the Waste Gate can run the excess to atmosphere, OR back into the exhaust or into the intake.

It is more complicated with piping for either to recirculate, but the options are there from GTM. For me, limiting at only 8-10 psi, it gets LOUD to dump waste exhaust out of a pipe unmuffled. I opted for an internal redirect back into the exhaust.

And the same goes for the BOV. The Tial's are the 'standard' which look great and give that unmistakable PPPSSShhhhhhhh when you let off the throttle.

Loud....

I chose to have (2) Synchronic BOV's installed from GTM and we recirculated the outlet back into the intake duct. Quiet release.

Do they affect power plumbed back in or out to atmosphere? Most will say there is more power to be had uncorked, but mine is the quietest and one of the quickest in the land.

So, you have to decide what you want.

Hope this helps.
