What temps best !
Discussion
Hi All...What is the ideal temp for a V8 wedge to run at, I've just fitted a 82 deg thermostat and it runs dead on 90 deg, before with the old stat it ran at 100+. With a 74 deg stat it runs at about 80 deg...so what would be the ideal temp for best performance to run at, any ideas ?
You might want to check your temperature gauge as they aren't the most accurate devices, on mine there's a couple of little resistors wired in series with the sensor which adjust the reading. I've found on my wedge with an 82°C stat the temp gauge says 82°.
Typically most engines run best with around 85°C water/ block temp while keeping the induction air as cold as possible.
Engines that are run at higher temps are mainly to reduce the radiator size.

Back to my original question...at what temp does the engine have the best performance
If absolute power is the only thing that matters to you, the colder the better. Most people are quite interested in engine protection/durability and economy, though. The hotter the engine is (within reason) the better economy you will get. But excessive heat (typically, anything over 100 deg would be considered excessive) also introduces the danger of hot spots causing engine damage, and raises mechanical stresses (through thermal expansion) that increase the danger of catastrophic failure.
Hmmm. Mine seems to sit at about 100deg all the time.
I fitted a new radiator, fan & thermal switch when I bought it about 3 months ago.
BTW the thermal switch was supplied by HHC so I expect it to be correct.
My first thoughts are to check it with a properly calibrated thermomiter.
Any thoughts on what's could cause what is almost a spanking new & watertight cooling system to run that little bit too hot. ?

Also has anyone seen the electric waterpump "boosters " supplied by www.mawsolutions.com ?
It appears they can be fitted with a timer so they will continue to pump water around the engine (the fan's on a timer too)for a while after the engine is switched off, preventing hotspots and aiding cooling.
They are also supposed to boost the cooling potential of the cooling system since the coolant will be flowing faster.
Apparently they're used on older engines & cars used in desert conditions.
Anybody got any thoughts on them?

They don't have anything like the flow rate needed to replace the primary water pump in a V8, but as a run-on pump (in parallel with the existing pump) they could help reduce heat soak, I suppose.

Steve - doesn't the 520 have an electric water pump?

No - I am looking into it but flow rate is a bit of an issue and I think I can spare 1 or 2 BHP to run the water pump. I also need to run this by John Eales but I think he will give me one of his "don't be silly but at least you've asked the question first" looks....
