2.68 MSCA 3" at the flange, moves
So your at about 91.5 percent of your 2.05 valve now?
Checked my notes the throat measures 1.85" avg dia, .310 stem so she is right on 90%. I've got some 2.10 ls3 hollow stems to go in, wanted to keep it around 2.7 MCSA. I'll throw up some pics when I'm done.

Good to hear they're stable, that's what I was aiming for, plan was to use the beehives I have.

Hey Ch*d, are those heads standing up on aluminum in the bottom pic? If so, does it reflect light in ways that would be problematic while porting? I'm trying to decide if I want an aluminum skin on my porting booth.

Edit: Sorry for the derail question. I'll be brief!

No, the numbers posted are without manifold. I probably left the w/manifold numbers at Randy's. But it really didn't knock much of anything off. 3-4 cfm in most places, 10 peak roughly.

If a dog does this with the flowbench running does it mean he has heard that noise a bunch of times? Or that he is bored with your results?

The dog might think it's on a plane ride while the bench is running.
