Re: New "Valvetrain" Advanced Tech Forum
I was going to ask Mike a similar question on a thread from a couple of weeks ago.
Things like seat angle, throat velocity, etc. came to mind. I was going to ask him out of all the data that a guy could get from a flow bench, what would be his most useful top three?

Lift point where port goes turbulent
Port velocity at MCA

Re: New "Valvetrain" Advanced Tech Forum
What's your take on low lift flow? Say, .050" - .200". My understanding is at these levels, the seat profile has the greatest impact. And for reference, I'm talking about the typically sized 2.02" intake on a Gen 1 SBC.CamKing wrote: ↑Tue Feb 04, 2020 10:02 amMid-lift flowRevTheory wrote: ↑Tue Feb 04, 2020 9:36 am I was going to ask Mike a similar question on a thread from a couple of weeks ago.

Seat AND valve profile. You can usually pick up low and mid lift flow by adding a back cut or two on the intake valves. And on the seat profile, I've seen improved flow by using 75 degree cuts instead of or in conjunction with a 60 degree cut.
