Blow off valve

[D&dgoblin69]

wondering who runs ether a s bov or a recirculating bov? How do you like ether one?

Not sure if an "s bov" is something specific but I have ZZP's 50mm blow off valve and it seems to work well enough. It's a very loud hiss. If you offered me another BOV for free that worked as well just to change the sound I probably wouldn't take you up on it.

I have used the Forge valve on previous Cobalt TCs and now on chassis #470.
