Default WTH?!? Whats up with these little motor fans?

A small rant...



I just have to say...Whats the deal with everyone jumping on the "little motor fan bandwagon?"

Does anyone REALLY think that these fans which push no more than 15-25CFM actually make a difference in motor cooling?

Cmon..the car's motor gets more cooling just from the fact that the bodies are open underneath than it ever could from a tiny fan.

I dare someone with a temp gun to run a back to back test both with and without the fan. 1 pack...known track...set amount of laps.

Then try to convince me that the 1C drop is worthwhile...

Default Don't have to dare, already done it....

Yeah, I've used temp gun before and it shows a drop. Actually, I did 4 packs practice run on Saturday w/o a fan and 3 more packs with the fan, at about 20 degree F drop by using the fan. Same motor, not a single cut on the comm, same set of brushes, about a tooth in gearing difference throughout the day. Now, whether that 20 degree drop is worth it to you, that's your own question.

Soviet you may want to read the thread about behavior in the forum, especially the part about language. Abbreviated or not people still know what you mean.

I've run them before and I did get about a 15F drop in temp. But I think that cooling the motor before the run helps more. I've got one of the Team Pharriswheel motor coolers that Jeff Pharris sells that attach's to the motor before your run and takes it down to about 35F before your run. That seems to give the best results for me. The motor is still about the same temp coming off the track after the run but it seems to keep the burning of the comm you get every run in modified down and the brushes seem to last more than one run.

15- 20 degree drops.

Additionally, a lot of people look at it like this, If my car is underweight, I'm gonna add something to help the car, not lead..."...Hmmm, 1/2oz of lead or a cooling fan..."

Lead never makes your car faster.

I found the same thing when I first started running one. Between 10f-20f. On my TC3 I have one because I need the weight there as well. But on my Mi2 the weight balances out perfectly with my BMI chassis so I dont run one because I would have to counter balance the opposite side with some weight.

Hmm, you may be right, but I have my fan pointing down, creating lift on the heavy side of the car......

Bob - Yeah.. I put a little fan at each corner of my car. When I put it on the scales, with the fans off, I am exactly at legal weight.

Once I turn the fans on, and go to the track, that is another story!!!
