Question about race fuel

[trost66]

Does race fuel run hotter than pump gas

110 octane

I believe race gas runs cooler. If you have 13.8:1 compression you should be running 110 anyway.

Pump gas ignites at a lower temp thats why you want to run race gas with a 13.8:1 piston, to avoid pre-ignition and detonation.
