New Electric Fan

nice work

 

that hotdog, he's good

i'm doing some math here, since i'm bored. correct me if numbers are wrong.

i read the stock fan drains between 5 and 15 horsepower from the engine, depending on stuff like temp of the clutch fluid, engine rpm, ambient air temp, etc.

that fan says it uses 18 amps. 18 amps x 13.8 volts is 245 watts. one horsepower is 745 watts. so it's using about 1/3 of a horsepower, which should be the extra power the alternator needs to make that 245 watts.

so by going to the electric fan, we could put 4 2/3 to 14 2/3 more horsepower to the back of the engine.

that's a heck of a gain!

 

Wow... I like that math!

 

best part of it is that extra power would be seen at low RPMs, since that is when the fan is draining the most

 

I'm not great at math but I like how that sounds too!

 

I do not have the formulas on hand, but rotating mass should also be taken into consideration. Rotating mass, whether it be in the drivetrain or an internal/external engine component that rotates, has on average 3 times the effect (in ET terms) that dead weight has. I know this from the racing days. If there is a mechanical engineer around, they should be able to throw some more accurate data on the rotating mass.

 

I'm doing the conversion soon as i can find a nice warm garage to work in.

 

Thats what i am talking about! As soon as i can get my hands on one of these flex-a-lites, I will be doing the same.

 

If enough people are interested in this fan, I should be able to get them at W/D. Maybe we could work out a group buy of some sort. First things first, the manufacture has to start churning them out.

 

I bought my controller for 70.00 and my fan for 85.00. My controller is adjustable from 0F-250F.

 

Hell of a deal, you cant beat that! I would imagine the W/D on that flex-a-lite is going to be around 260-290. The more i got to thinking about it, with the size and weight of the package a group buy might not be feasible. I will look into though.

 

@ Cobra: What fan and controller did you buy and where from? I couldn't believe the fan at Summit was $377. OUCH!
