Aluminum heads

YR, I don't believe your 11.1 engine will maintain 160 degrees on a 100 degree day with 4.56 gears. I'm sorry I don't buy it.
and it wouldn't do it with an aluminum head either. compression creates heat.
I do believe you are able to run 11.1 on pump gas without detonating, but you would not with a 1-1.5 compression increase even with an aluminum head.
The heat has increased in the combustion chamber with the added compression. lol

I can get it to run cooler that that. How do I know? I tested it. And sent the written results to Evans so they could see it. I should have taken a video but they just wanted me to do a test.

Like I said...my original intent was block the bypass and not run a thermostat. IIRC, on a hundred degree day at road speed I could barely get 140 out of it. It would creep up at stop lights but never got over 190 just sitting there.

So I was forced to run a thermostat, just to get some temp and them to control the temp.

My cooling system was thoroughly researched long before I bought my first parts. I'm currently running the pump 6% over and if I could find 10% over pulleys I'd do I in a New York second.

My next engine (if everything goes as planned and right now, the old ball and chain and my boy are trying to derail everything but I'm working on that) will be 12:1 on iron heads on pump gas. It's doable. I just need to spend some time doing the research first.

If the aluminum head theory is correct, I should be able to run 13.5:1 on pump gas with aluminum heads and even I don't have the balls to try that.
