Webb9 juni 2024 · Hi, I have some questions about the relationship between a compression increase, a/f ratio and cylinder temperatures. Let's say a theoretical engine with a 10:1 Compression Ratio is tuned to perfection. You then take the same engine, and increase it's compression 1 point, to 11:1, with no other changes, and run it with the same fuel map. Webb26 okt. 2016 · These qualities of higher compression are especially beneficial to the street car enthusiast who despises good traction. In my case,I went from 7.88 to 9.29. I was initially shooting for 9.0 and chose piston specs based on the 46 cc advertised combustion chamber volume of the TA SI cylinder heads.
