You're missing the point here. Dropping the engine temp only increases the ping threshold a little. Hotter/cooler air and fuel have a much greater effect. Ideal for high compression is reverse cooling flow (heads first, then cylinder walls), a 180* or 195* t-stat, and cold air coming in. For FE, the same equation with warm air would be good (although not as high compression). Running the engine too cold is counter-productive, and also increases wear.

i looked at the pressure of fuel online at 140 it says it will hit 29 psi but if u have a pressurized system the fuel will stay liquid tell injection and thats all i was saying, and from what i read lower temps only increase wear if u try it in a used engine thats broke in at higher temps with lower tolerences if you build a engine for the lower temp and higher CR then it's "SUPPOSED" to work i guess
