Title: Measured volumetric efficiency of 1.8T and 2.7T engine
Post by: BlackT on March 23, 2022, 09:52:20 AM
Is there some data of real VE of these engines
4000-6500 RPM is area I want to know how much is VE
Using measured data I come to about 85% VE in this area.
This is rought question, I am okay with 5% precise
Is it possible to read it from some maps?

see KFURL and such. The 20V head is pretty damn good. Someone also did some testing way back on audizine that gets close.

pressure -> load
