This is a low cranking compression, especially when you compare it to engines like the ZZ4 350ci/345hp crate engine that makes around 190 psi or the current HT 383 with 9.1:1 compression and a big ...

Compression Ratio = Absolute discharge pressure/Absolute suction pressure Most technicians realize their service gauges read zero when not connected to a system, even though there is a pressure of ...

One reason for its success, other than the cylinder heads, VCT, and intake, is the bump in compression ratio from 9.4:1 on the '99-'04 GT to 9.8:1. Our plan was to take one engine and test it with ...
