[Fot] TR8 Water temperature

[Spitfire Racing]

Easiest way to confirm a water gauge is to immerse the sensor in boiling water which is a known temperature as a reference.

I hate to ask Chris, but I've seen this before: are you sure your gauges are accurate? I saw this problem on a well known car a while back.

Electrical or mechanical?

Could be worth checking.

Good luck.

Bill

Hi guys,

 

My TR8 is running way too hot about 212F at full speed and at idle the temps are getting that high also. I have no idea to get them down.
Radiator core is 68x48cm x 5 cm. I suppose that should be enough. I've experiment with different restrictor plates with no change. Changing pump speed didn't help either. The difference between radiator in and outlet is 10°C (50F). Not enough I would say. Maybe making the pump more slower? It was running on a ratio of 0.8 slower than crank, currently 1:1 speed. Any ideas? 10 Liters are circulating.

 

Cheers

Chris
