Re: [T3] Compression Ratio Recommendations


<x-flowed>we can add to cylinder heat temps that fact that an exhaust isn't matched to its motor! you have a big motor, moving lots of air you hvae to get the air out. even worse, if you have big valves, and a small exhaust, you loose all port velosity and can't evacuate the air charge from the chamber efficiently enough. basically, if you have more than about 110 cfm of flow capability in your heads, you need to run a bigger exhaust!
