Exhaust Gas Temperature

Post by Wally »

Hi Jake,

In your testing, what gave higher EGT's : engines with higher compression ratio or the ones with lower CR?

Thanks,
Walter

without a doubt- Lower CR.

Higher CR gets the fire started and over before the exhaust event ever begins. Low CR pigs still have a burn occuring when the exhaust valve begins its event.

Inefficiency kills EGT.

I set mine to run 1150 or so at wide open throttle with a 75BHP load...
