To test if a running fan is an impediment at say, 70 mph, here's an easy test for those with easy to remove fans.

Cruise at 70 mph on a hot day with both fans on, read coolant temps.
Pull over somewhere, remove 1 fan, repeat.

Why are high coolant temps bad, aside from localized boiling? Can I feasibly run 275 degree coolant temps using Evans?

My friend uses that thick springfield racing radiator on his 460hp miata that sees only tracktime and he doesnt overheat anymore.

You may ping despite lack of localized boiling, then you have the materials - the piston may expand too much, the oil seals may suffer, the exhaust valves ... I saw a testimonial wherein they lost a fan but pressed on despite very high temps. Upon teardown the only damage was to the oil seals.

There also seem to be testimonials from Harley and other big bikes about Evans, IIRC about cooling improvements in stop and go traffic. Another one I recall is from off roaders. Notice these are low speed - I don't know if this is relevant.

@Savington: what exact setup do you run now?
Radiator?
100% pure water? Water wetter?
Reroute, how?
Heater core?
Thermostat?
IC sealed against radiator?

Yea hes pretty fast. Well fast enough to be able to run down a 600hp corvette at road atl. and roebling. I'll get his shop number so you could call him if you want. He'll talk aero and cooling efficiency all day. His dual oil cooler setup is interesting too. This is his car (it was bright that day)

Very interesting. I would have thought that even with a 40 or 50 degree increase in coolant temps, the expansion rates of the pistons and such would depend far more on EGTs and intake air temps.

The setup is just two NACA ducts with piping inbetween them and a plastic shroud ziptied onto tiny oil coolers. Its pretty straightforward. If I had pics at the moment I would post them

I'm not 100% certain about this, I'm speculating.

link? That looks somewhat acceptable.

I already like that guy. Savington just sent me a PM for some advice on attracting another man, so hopefully those two can hook-up...if you're friend is a power-top of course.

Haha thats hilarious. Surprisingly he has no pics online since the car was just recently built like that. He easily has 50k into that car including the base price. The only reason hes using r888s is because if he would use anything better they would bump the car up a class in the series he races in. Atleast they're 245s on good rotas. I wish he were a member. The shop specializes in miatas so im surprised he doesnt have an account on here. But if anyone really wanted to talk to him, i'll talk to him tomorrow and see if hes alright with me giving his number to anyone in need of advice. His name isnt Ru Paul though. Next time I catch it on the lift when im there i'll snap as many pics as I can get
