Saturday Night Racer - Overheating question

17t_racer LMR God Offline Addicted to dirt! Posts: 524	Overheating question 04/06/10 at 8:10pm Does anyone know how to keep an engine for getting hot. The last race I raced it was 50 outside and the motor was running 235! That is a little warm for me. I have a brand new double pass radiator in the thing and we have good airflow thru the radiator! You can IM me if you want! Thanks Bryan Terry 17t Hobby Stock

hey a few things, 5/8 restirctor, you do not need a thermostat in a hobby....run an external overflow tank for the radiator and fill it from there... always fill radiator from highest point... also check your plugs, you may be running lean and need to fatten her up... running lean will make you run hot. how good is your fan shroud? your fan should be half way in your shroud. pop rivit a piece of plastic directly under the radiator hanging down, it will grab some air and force it up. these are all some of the things i did when running a hobby, and it worked...

one more thing, make sure you have enough holes cut into your nose piece... dont run the plastic fans, they suck, the 4 blade fan is the best...

last but not least, the best thing on the market for cooling is called "30 bellow" you can usually get it at pep boys, if they dont have it, i know paul williams at pws machine has it... it is bad ass stuff! you just put it in your radiator like water wetter but way way way way better
