D16Z6

more d16z6 head development. achieved 202cfm at only 0.387,  it's the oem valve lift.
cfm raises up to 207 at 0.4 valve lift, enough for an aftermarket camshaft.
stock intake manifold shows a loss of 10% of airflow volumen and speed.

did some calculations:

98,960 Cubic Inches @ 6600 RPM with 135,00 % Volumetric Efficiency PerCent


Peak HorsePower calculated from Cylinder Head Flow CFM only
600 RPM/Sec Dyno Test Lowest Average Best Potential
Head Flow Peak HP = 205,8 215,8 225,9

Minimum  Intake Valve Lift to prevent Choke = ,299 Lift  @  6600 RPM
Minimum Exhaust Valve Lift to prevent Choke = ,285 Lift  @  6600 RPM
Intake Flow CFM @28in RPM Range = 5106 to 7106
