hi all
fitted a temp sensor to my polini 210 just wondering if anybody knows what avg running temp should be and whats the max temp they can run at without a seizing up

cheers

I ran a TTO temp gauge under the plug and on my o-tuned P200 a safe running max was 320F. It did go a lot higher in heavy load conditions, up to 380, but 300-320 flat out in 4th is pretty safe.

My alloy Polini 210 runs in the 300=340f range normally, I have seen 400f on a hot day under load, timing 18 degrees, squish 1.4mm, never had any issues.
