I have been looking in to putting a bov on my truck. I know some of the guys on here are going to say to research the forum i didn't find what i was looking for. Here is why i am looking in to putting one on... i did my pushrods and valve springs gained 2psi. Went and seen what its got at 3/4 throttle 27 lbs of boost 130 mph. When i let out all the pressure hit the tranny really hard. So i need another way of releasing the boost. I know they don't make vacuum.but what about the intake or the air intake. Help is much needed to figure this out. Sorry if any wierdly spelled words did this from my phone. Its got auto correct.
