Perhaps I should have been a little better in my wording and have said, “Close to my W5” since a thin port stopped further porting. 312 cfm is a bit shy of what these heads have been known to be able to do.
Who’s done a chink head past 312cfm?
Yea, true, but until I see someone or I myself have it done and outperform the W5, it’s all theoretics from paper work and flow bench testing.
Is it possible the chink head out performs a W head?
IDK, it’s have t seen it yet not that I’m at the track often enough to know. But until I see it….
