IS 1g bov loud?

HOw loud is the 1g Bov and whats the Psi level compared to the 2g plastic one?

it can hold up to around 20ish psi when crushed. The stocker 2g plastic leaks around 11psi, both personal experience. You NEED to recirculate it, so it won't be that loud. If you want LOUD and recirculating, check out the HKS SSQV + recirculation kit, or the greddy RS or S. If you choose not to recirculate, all of them will be loud, but it will damage your car. No doubt there.

Mines uncrushed and I hit 21psi on it, so I think its more then 20 when crushed

Please stop posting 50 threads a day half of which are already covered by other threads you've started. This is no different than your other 1g BOV thread, just continue the conversation over there ;)
