Hello everyone,
I am at a loss.
S197 mustang with a lowly 3v 4.6 making 315whp.
Yet, somehow, I can get the ECT's so hot in weather that is over 75°F, that the car will cut power (pull timing) on me. I have an autometer gauge that's taking coolant temperature in the engine block. Cruising, sits at 190°F. 7/10ths pace on track, reads around 220°F. A lap at Race pace, the gauge will hit 230°F, car will cut power. If I continue to stay in it, the car will get up to 240°F. I've never pushed it beyond that for obvious reasons.
Why is it that nobody else has this problem?
Keep in mind, my stock coolant gauge shows no difference between 190°F cruising and 240°F overheating. So before you answer, please read this Disclaimer, because it happens every time I ask this question:
Before you reply saying you can run your car 10/10ths in 100°F ambient heat without issue, please consider that you are either not driving as hard as me, you aren't able to feel the car cut power, or you don't have the level of information that I have in regards to temperatures because you are relying on the stock gauge.
So to summarize I'm looking for good data from people who genuinely have a car that they can beat on lap after lap in hot ambient temps. Maybe this is a totally unrealistic expectation? But I'd like to think it isn't considering the FR500S program, spec iron cars, BOSS302S cars, etc.
Or, I am looking for data from people who have done the following mods:
