electric fans?

[justtwistit]

has anyone thought or done this?
i know everyone is using airscoops but i was thinking the other day about maybe using a electric radiator fan
i think it would greatly help out cause then even if ur sitting still u could still move air across the cooling fins unlike the airscoops that only direct air when moving
or better yet have airscoops and a fan to direct the air that the fan is moving!
idk if this is possable or not but i thought it was a concept

idk if the stator will have enough juice to run it

little more brainstroming here

i also think it would be nice to be able to turn the fan on and off so since i don't have a head light maybe i could wire the fan to the headlight swich and then i would also be able to go from high to low
how hard would that be if i were able to wire up the fan?

ya thats true i didn't even think about that but it might u know depending on all what u have hooked up like lights, etc.

you will need to findout the wattage of the fan

Hey! I've been thinking about trying something similar. It's very possible to hook up an electric cooling fan to your Blaster, but it won't be a one-weekend job. My idea involves using a couple of small box fans, like those you find inside computers.

The problem with using one big 'radiator' fan is that the fan motor is simply too much for the Blaster's electrical system to handle. You would also need a relay to run the big fan, as well as the associated wiring and switches. This could all be done, but the Blaster would have to be fitted with a full-size battery, and the voltage regulator wired up in such a way as to charge this battery while the fan motor draws power from it. If a big fan were to be run directly off the current produced by the regulator, the motor would run poorly from a lack of steady input voltage, and you'd likely either burn up a regulator or lighting coil.

As for using 1 or 2 smaller fans, I bet these could be made to work with less effort. I'd still install a small, sealed battery under your seat, and tie it in with the voltage regulator. Why? Ever notice how your lights increase in intensity as the engine revs higher? This is because the lighting/charging circuit's voltage output is dependent on engine RPM. A cooling fan would not be very effective if it idled with the engine. By installing a battery, the fan would recieve a full 12 volts of power all the time, regardless of engine speed. As for the regulator? It could just charge the battery as needed. In theory, you could also isolate the lights from the rest of the Blaster's circuitry, running them off the same battery as the fan(s). The charging coil and regulator then just become the charging circuit for the battery.

I've never tried anything like this, but as long as low-wattage fans are used.... You still run a small risk of damaging something by experimenting, but, hey.... It might be worth a shot! Those small fans should work just fine with only basic wiring and a strategically-placed switch.

have to be a 2 speed fan as well to have a high and low setting

I wouldn't try it without the highoutput stator.. Hight output ones put out 75 watts i believe

ok thanks everyone for ur input!

phragle made a post that explained how to set up a blaster with high power lights an a battery heres the link

Jus thinkin about it and I think it will definetly work with a nice stator...

 

[Awk08]

i tossed that idea around for awhile, and believe it has some use, i even have saved in my ebay a streebike fan that looks like it's the size of the frame in front of the motor, i think like $20, never worked on how to keep all the mud out of it, so shelved the idea, and i believe the little muffin fans from a computer are ac voltage not dc ???? and dont throw much air

A fan sounds like a good idea to help cool the engine when you are sitting still, but wouldn't the fan itself actually block some air when you are riding, especially if you don't have it running all the time. I think it is a good idea if it would be effective, but for all the hassle of wiring the fans in and mounting them and everything would it actually cause the motor to run much cooler at all. Thats just IMO but it would be a nice mod if it could be designed to actual lower the engine temperature by a noticable amount.

I don't see small computer fans working. You would need a lot of them to cool your motor. And rideyamaha09 brings up a good point, the fan could block the air when driving. If you think your Blaster is going to over heat from idling then turn it off. Blaster have been made for than 10 years with out fans I don't think you have to worry about it.
