Found this on another site:
CFM @ 25" x 1.058 = 28"
Therefore
All rounded to the nearest whole number.
Yea most software will compensate but it's not 100% Eric Weingatner on YT shows this on his Saniez bench he also has a SF 600.
It's close though. But again on a 350cfm head on the Saniez the SF 600 will flow 360cfm both @28 actual gauge vaccume.
This is why I will get the SF 600 numbers when I pull my heads.
Then on Aussie V8 there's plenty of Iron port jobs Member TK has done with flow numbers posted.
But as Eric always states you should do .200 to 1.000" lift numbers and you should look at the .400 the .600 and the 1.000 and the reason is the 1.000 numbers tell you how stable the port is. So I'll post the .200 to 1.000 numbers.
The .100 numbers are uselss because they always are inaccurate because the bench tries to suck the valve open which can add .005 to .015"
