Thread: Any idea of the CFM of a VE head?

Hi team, who would know the flow, in CFM @ 28" of a healthy VE head?

TIA.

So I wanted to get the VVL head flowbenched, just to have some figures in hand and verify what I had been seeing on the web... The top numbers are the VE head and the bottom numbers are from a highport SR head.

Flow test was done on a completely stock SR20VE head. Machine used was a Superflow 600 test bench at 28" of H20 and low 80's temp.

SR20VE
Intake
Lift CFM
.050 49
.100 86.2
.150 122.6
.200 158.6
.250 192.5
.300 225
.350 249.2
.400 263.5
.450 272.9

Exhaust

Lift CFM
.050 46.5
.100 86
.150 118.5
.200 147
.250 171
.300 183.5
.350 188.8
.400 193
.450 196

For some added information, I've done some search on Highport heads and found these numbers...
