tips to keep the rotary cold
hey team, i spin yarns with the guys all the time here and there about good cooling systems, i havent overheated any of my rotarys in the past but if i were to enter the local burnout competition i want my engine to last the 3mins or so you get given to smoke the tyres, bit of a novelty here in new zealand :).
im thinking an aluminium radiator? a large electric fan that covers both the radiator and the oil cooler, oil being a 3rd of the engines temp. also the size of the water pump pulley?? i know that the internal propellor can spin so fast that it stops circulating water but what size should that pulley be?? strong radiator hoses etc etc? oil cooler fans i have heard of mini motox fans that can fit, i dont have much experience with this sort of thing but would be good to know |

Do they put a big fan in front of the car, like they do on the dyno? Like this:

Re: tips to keep the rotary cold
*Flush your system well and make sure it's clean...no rust, setiment etc.
*Use as much distilled water to coolant as you can get away with in your climate *Good ducting is as important as the fans themselves IMO. *If you have forced induction..consider AI. Doesn't have to be fancy either. Just water-only. *An efficient radiator is as important as size. *I've tried the coolant additives...."Purple ice", Redline "Water-Wetter" etc. They didn't hurt anything, but honestly I never saw much difference in my indicated temps vs. without the additives. Just my .02. *Probably won't make much difference in burn-out contests since you're not moving alot, but anything to reduce under-hood air pressure, i.e. a vented hood can't hurt. That will improve flow thru the radiator. |

Unless your car is heavily modded, I doubt you will overheat it in 3 minutes. You shouldn't be using anywhere near full power just to keep the tires spinning.
