I just wanted to share with you guys the flow number for my heads using JWT 400# Cams, and 1mm oversized Ferrera Valves. Those cams specs are
268 intake and exhaust with 9.5mm lift. They are the new cams which replaced his last generation of cams.
Lift-in Intake Manifold Exhaust %loss
0.050 50.00 48.0000 53.0000 9.4
0.100 91.00 85.0000 89.0000 4.5
0.150 136.0 128.000 124.000 3.13
0.200 175.0 161.000 153.000 5.00
0.250 214.0 182.000 167.000 8.25
0.285 235.0 188.000 172.000 8.51
So the max numbers are 235 CFM for intake and 188 exhaust for just the head. However the Max flow number was 172 CFM. A good thing to notice here is that at higher flow numbers the percentage of loss increases. Also it interesting to see that as the lift increases the flow for the intake increases. The question is what would happen when VTC kicks and advances the intake side.
I am happy with my results but I am kind of wondering what my results would be with some Tomei 270 high lift cams :-) Mallace I can ship you my manifolds now also. But you can tell what kind of results you should be expecting.
