A warning about Evans Waterless Coolants
Consistent temps lessen wear for sure, and thinner oil makes horsepower.
We agree on that.
Not everyone is out to trade horsepower for reliability and longevity.
The facts are that neither one of us apparently knows the deal with Evans coolants for sure, and that's one of the reasons I brought it up.
Unless you know for sure and just haven't told me. :D
I said I'm finishing my crap now. I said I'll post results, good or bad.
I also said, ebooger and evidently, some of us on here, went to a COMPETITORS web site and believed every last word but didn't actually verify anything.
The thing about Evans coolant is, if you are NOT going to listen to what THEY say, and do your cooling system the way THEY tell you, how can you expect results? You can't have a restricted system (you can say the same thing for any coolant system), you don't need a pressure cap, you need to keep pump speed up, not lower it and a couple more things I forget at the moment.
I'm running my compression ratio fairly high for a PG DD and one of the ways to make that feasible is to lower coolant temp. That's why I looked at Evans. Cool temperatures don't wear out cast iron. Uneven temps can, but it's usually piss poor material that causes it. Every 2.8 Chevy I ever did had big ridges in th front cylinders. You could tell when honing them they were butter soft. I'd venture to say that not all those 2.8 chevies were using Evans coolant, yet they were wore out. The inline 6's are bad about it too, but most are soft as well. And since most folks hit the key, and have the thing in reverse before the second cylinder fires, I have no doubt what some of the block wear issues are caused by.
