They aren't fast but last multiple race seasons in our rx-3 PP. the ones with stainless outer sheet usually failed in 1 or 2 races. we run max 950 egt but run the engine mostly between 7 and 9k rpm.

Hi Mate,

Yes the heat transfer is the issue.
My probes are Inconel 600 as you know these are the only things that last, SS is cheap and nasty not suitable for anything but maybe 2 stroke bikes etc.
If you want some or more detail etc shoot me an email peter@riceracing.com.au
I took my latest video for a bloke on here who wants to use these for turbo compressor exit temperature, they are very fast.

Will take a look at your video now
