I am looking for numbers on flowrates of the different big name BOVs. so here it goes. Which one of these valves moves the most air with the best response?

I did search a few different terms so please no "try a search" posts. thank you.

1: HKS - SSQ w/ purple insert (not sure if the insert makes a diffenece in flow rate or just sound)

2: Greddy - Type RS 40mm Valve

3: Blitz - DD

any help you guys could offer if you have done or have any documents on flow tests of these valves i woud appriciate it.

Thank you for your time,
TR

 

From a build only perspective the GReddy Type RS will flow the most. It has the largest valve out of the three you listed. If you are worried about all out flow of a BOV then pick up a Tial BOV. As far as I know it's the largest BOV on the market at 50mm and is made to flow massive amounts of air. But it seems that you are wanting to flow good amounts of air as well as have the "cool" laser type sound. In that case then just stick with the GReddy Type RS.

TIAL 50mm.

 

I went with the type rs as well, will it do a good job at 20 psi???
