Question about VE (Volumetric Efficiency) of SR20 Heads

[2_Liter_Turbo]

I'm trying to figure out some tuning options with my SR20DET. And I am curious if anyone knows what the volumetric efficiency of the S13 SR20DET Blacktop head is? According to Garrett, it should be somewhere between 92% to 99%.

Anyone?

imo your engines VE changes way too often, and rely on too many variables for it to be a factor in tuning your car. e.i:Air tempintake manifold air tempelevationhumiditythe list could go on and on...i would focus on having good compression, and then let your ems do the rest. some days it will run better than others.

But there must be a base VE for a stock SR @ sea level with some sort of standard humidity. I know it will vary from day to day, but I'm just trying to get an idea...
