Keeping engine cool on roadcourse
I'd like to know about the t-stat killer as well. I assume it is for the oil cooler thermostat. I don't know if you can just disable it or need to buy something.
As for the factory gauge, I think it is just like a dummy light. Mine moves to a certain point, and then never moves. Whether it is on track in 95 degree heat, or idling in the winter it stays the same. A real gauge should have more fluctuations than that.

On the topic of cooling... I was talking to a sportbike guy and he said that he runs a higher content of antifreez. Instead of running 50/50 hes running like 70/30. Im not sure how true this theory is but would it work with cars?

Sport bikes are impossible to keep cool though so theres not much you can do there,
Sorry, BAck on topic.............

I haven't noticed any cooling issues on track, the OEM water temp needle doesn't move at all. This is in 95 degree heat. Stock works just fine, unless you're doing some sort of endurance racing, I don't see the point in replacing everything.
Accusump pump for when you turn the car off... other than that, my water temp has LOWERED below normal running temp due to the high wind speeds. This is in Vegas weather too, there's never been a single problem with my engine heating up too much (I do use heavier weight oil, though 20w50 Redline Synthetic for Turbo or Supercharged cars), brakes... are another story. But one that can be fixed with racepads and some Super Blue.

Here're my "budget" solution to cool the car down for track use:
1. Tomei oil thermostat killer. HKS apparently makes one too.
2. Ralliart water thermotstat. This IIRC reduces the 'trigger' temp to 71C (i.e. at 71C the water starts flowing to the radiator, instead of the stock temp of 80's?? Sorry if I'm wrong with the details)
3. I had my mech run a T-junction off the intercooler waterspray; he installed two nozzles spraying the radiator, one nozzle spraying the oil cooler core.
After doing all the above, my car can stay out relatively long. What I do is on the straights (when my hands aren't too busy turning or shifting), I would press the manual intercooler spray button. This will cool down the oil and water temp as you progress through the lap.
I just wish there is a low-level warning indicator for the intercooler water spray tank. Whenever I see oil temp reaches 130C and refuses to come down, I would pit in and sure enough, the tank is empty.
My mech actually warns me about this: the pump of the I/C spray is water-cooled, so it's not a good idea to press the manual spray button without water inside as there is a chance the pump will overheat.
I may upgrade to boot-mounted high capacity water tank in future.
If you have the budget, upgrade your radiator and oil cooler, I'm sure it will do wonders. GOOD LUCK!
