OVERHEATING

RRR I hate to disagree but.... (You know me :rolleyes: )

Nascar run typically 230 to 260 deg F

And yes the engine clearances are tuned for that temp.

and they run that temp for hours.


the cooling system is also sized / setup for the heat being transfered.

How big of a cooling system do you think it would take to cool an ASScar engine to say…160 degrees?

One it would be HUGE. That add weight. Plus the amount of air flow to run that temperature for hours on end would also be HUGE. That shoots the aero package right in the ***.

Just because ASScar or Pro Stock does something doesn’t mean it’s all applicable to what we do here. Pro Stock CHILLS the engine down to some crazy number. IIRC at the END of a pass they no hotter than 140 degrees.

Are they stupid? No. They KNOW cold engines and thin oil makes horsepower and they don’t need to worry about engine temps for 3-4 hours.

For a street driven engine 160 is about as hot as it should be. With that I can run far more compression than most guys even think of and not get into detonation.

Cold engines make power. To argue this is nonsense unless you are a classically trained engineer.
