Default 2 bov's?

Well I'm in the middle of swapping my intercooler from the air to water that came on the car when I purchased it to a air to air. It had 2 bov's on it. One is a tial 50 mm and the other is a turbonetic's raptor. My question is should I keep one or both? And if just one which one should I keep?

Depends on how much airflow you're relieving with those valves. If it's enough airflow, you sometimes need two or more to keep things alive.

I've heard of running more than one BOV when you're tight on space and can't fit one valve big enough to relieve the airflow. Or if you want your car to sound like a jet.

Most of the time you see 2 or more on race cars...that are making 40+ PSi.


If one of those valves will support the amount of airflow you need relieve then you can just run one. If not, you'll need both.

OK I'm thinking with a t76 Turbo and 14 psi on my 408 motor. And the air to water is only good for 675 flywheel HP. I'm hoping to make 750rwhp
