TF & Speedmaster Flow Tests

I'll answer, but you should listen to others with more experience than me. I welcome the correction. I think in general for flow testing at 28", velocity over the SS floor of 350 is good, high 300s is borderline, 400 you're in trouble and 450 is insane. But it all depends on the port. A port with a 10 degree valve angle (and a high port) should be able to handle higher velocity over the short turn without separation than the 18 degree SBM. Hard to get low velocity over the SS in SBM running high cfm. Looks like TF did a pretty good job here.
