[Fot] TR8 Water temperature

[MadMarx]

Hi Justin,

 

water wetter is only a cure for symptoms but not removing the cause.

I would like to find the cause before trying things.

 

Cheers

Chris

I can't speak to its use for racing, but I swear by this stuff.  I used in in my street TR4A for years and any vehicles I've owned that ran a little hot, etc.

Interested to hear others on it especially relative to racing.

 

I did own a TR8 for a few months.  I recall it ran hot and it frustrated the hell out of me in general.  (Water Wetter wasn't on the market then.)   I scraped my knuckles one too many times under that hood.  It was so cramped compared to my prior TR7 and TR4A.  I decided it wasn't did me!  So I never discovered why if was running hot.  (All street cars)

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
