Author Topic:   to fan or not to fan

Im curious, i cant get my engine to run over 170 at the end of a 15 lap race when i get on the track its at about 140, the fan is about 1/2 inch from the radiator without a shroud. how harmful would it be to just completely remove the fan so my engine will be closer to operating temp when i get out on the track.

I have seen guys do this in a pinch but they had to keep moving otherwise the car would heat up because there was no air coming through the radiator. I would try to find another way to get your temps up without removing the fan. In the past we have covered part of the front of the radiator with tape or something on a cold night to help keep the car warm.

What about leaning it up a little

I'm with 6m on this one. Check the plugs and maybe lean it out a little.

Do you run a t stat? I have used a 160 for the last 4 years and run around 180 to 190 all the time.

I'll bet there is a lot of guys reading this that wish they had that problem. I bet the motor could stand to be a bit leaner too.

Can I damage my motor by racing it when it doesnt get warm enough? Its under 170 when I go out and might get up to 190 after the races. Should I use a thermostat?

Scoot, Never heard of hurting it unless it is so cold the oil thikness strips your pump drive. The biggest disadvantage is loss of power. Most believe that 220 is, I would rather run 170 to 190 and never worry about temp in a long race.

Wheels47, you say "still" when talking about gas. You do know alky runs much cooler than gas...right?
