I think 2 themostats, AKA valves, would work , one stat. temp. controlled, second valve, stat. contolled by boost pressure, Im working on a thermostat housing setup now, you need a very fast flow quickly when you go into boost, because you dont want to overheat that spark plug area, in fact possibly extra water ports near there! RON A lot of time spent in this thread about tuning instead of cooling , any time you add fuel or take out timing you lose the race, Like they say (LETS COOL IT)

 

NPG+ by the catolog says it is 75% P/G and 25% E/G just to make it flow easier, but I have used the early formula, which was thick, 1989 in a big block camaro, It would spike to 220 F at 1st out on road , but then as it warmed up it would thin out and be fine, but it never boiled even it spiked to 260 F no pressure system large capacity pump, no gurgling. ever. with 70-30 EG water damn thing was always over heating in traffic, waiting to get into car shows. YEP works for me , MAN I thought I had a secret OH WELL! RON

 

I was not questioning your creditability (or Evans). To you the truth is obvious but to me I must trust what a stranger said on the internet. I say "God exists" from my own personal experiences so should you believe me just based on what I say? Even if I explained to you my experiences you might still be skeptical. I do have more faith in you and what you say now and it appears you are reliable and legitimate . I learned something hear. Thanks for your input.

 

Has anyone logged oil temp and coolant temp using Evans?
