Thanks shimmy

I had to get my daughter to explain to me first

I fitted underdrive pulleys to slow down the water pump (and alternator) and extend the life of those parts, wouldn't want either running faster!

Nathan is it not causing an issue to the cooling ? Slowing down the water pump ?

Doesn't seem to be the case.

I actually wonder if the high speed of the water pump is causing cavitation at high RPM running on track?

I had underdrive pulleys for a while, cant remember when but will check data and see if had overheating problems still with them in (def no problems at normal speeds or stopped)!!

Very interesting.

Another possible contributory factor maybe.

Very true, because as soon as you back off, the water temp drops immediately.

Not convinced

My feeling is it is throttle related, not revs. I can be at full throttle but not full revs when the temps start to move

If it was water cavitation it would be caused when car runs at max revs, not max throttle/fueling

Is it that instantaneous?
