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.

Who is your friend? Is he actually fast?

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? |

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.

can I get more pics of that oil cooler set-up?
Where did the duct come from? |

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 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.

C'mon man. Everybody knows Ru Paul only drags.
Savington: ru paul Savington: if that's his name Savington: tell me about him Savington: cause his shit looks fast Savington: or it looks like it could be fast Savington: except he's on R888s, lol :borninthe90's: |
