anyone running a colder stat?

[Gadgeroonie]

Has anyone tried a colder stat to keep the engine running cooler. I reckon i can get some 80c or 85c stats that will fit our cars

should take the strain off the cooling system on track. You might even be able to plug a oil/water cooler into the system

[Gadgeroonie]

do you mean it will take longer to warm up to say 80C ?

a friend of mine works for a company that supplies thermostats

he is going to get some part numbers of cooler stats that will be compatible with our cars

I think i've mentioned this before, on the race car we drilled small holes around the stat, so would have the same effect, I think someone said this is a very bad idea.

it is a bad idea on a road car because it takes the engine a long time to get up to temperature

many racers remove the stat altogether

at the end of the day the solution is to fit a more efficient radiator - but if you already have done this then a cooler stat will let the cooling system run cooler and have a greater buffer when the going gets hot

drilling holes is not the same as fitting a colder stat - very different

car will warm up as normal with a cooler stat till it reaches temperature

with the holes it will take ages to warm up

Hollowpockets i think you may be mistaken about the warm up time. I can speak from experience, one of my other cars has been running with holes drilled in the stat it takes about 10 miles to get up to temperature. The new 82c stat was fitted and it gets up to temperature in only a few minutes.

The car now has a lower running temperature

Andy - do you have the part number for the stock Noble thermostat handy ?

[Gadgeroonie]

has anyone got a spare stat - i can take it into the dealer and he can match up a cooler one the correct size

(i have a spare St220 engine is the noble stat the same part ?)

[Gadgeroonie]

How do the scooby ones work ?

[Gadgeroonie]

i need to take one in to the supplier to find a cooler one that matches

need to know if the one in ours is the same as an st220

[Gadgeroonie]

missed that somehow

when i find time i will take the stat out of my 220 engine and take it down to the parts guy - he can match it up with a cooler stat

i fitted a cooler stat into the wifes golf and it has cured the hot running

[Gadgeroonie]

just checked the st220 engine and there is no stat on it !

where exactly is it on a Noble

[Gadgeroonie]

part no please
