i think you might be looking at a lot of work for some thing that is less than $30, you may not need the big super cooler. i run with out a fan and just wanted the cooler for in case. with the ski's you may need more cooling, i do remember my fan coming on a lot in the snow, now that i think back on it.

 

well in the summer months my fan was on alot(and thats with engine ice in the rad), and this year i want to prevent that, and i have 3 weeks left of my shop class, and all i really have to do its about a weeks worth of work, thats including making a bar riser block with DS650 engraved in it, so i'm not worried about time, and money wise the canadian dollar really sux right now, so it would probably cost me over $50 canadian to buy one when i could make one for next to nothing, and mine is opposite to you, in the snow it only comes on when my rad hose pops off [img]i/expressions/face-icon-small-mad.gif[/img]

 

I got a 20 fin cooler off Ebay for 20 bucks. Look there. I am pleased with the quality.

 

i ran my 760 for the first time on the ice this weekend, ran real good til about the 20th lap, hot light came on anti-freeze pumping out of overflow. let it cool down ran it again seemed fine until i ran it hard (8-9500rpm) for another 10 laps got hot again. i ordered a super cooler and a bottle of water wetter hope this does it? i know water wetter in the drag car helps alot, does the super cooler help that much?

 

it goes in line with the upper hose?

 

well do u think my really big super cooler idea would work? cuz i'm gunna have free time and i'll need something to do, unless you can think of something else i could make, i have access to a lathe and a vertical mill, any ideas?

 

lilnotts,

If you look at computer heat sinks, the ones that cool better have thinner, slightly more tightly packed fins. This sort of thing could be very bad on an ATV though, anything thin will break. Your goal while making this, would be more surface area. The more surface area you create the better the cooling will be - sort of. For the extra surface area to do any good, you have to ensure that it gets good air flow across it. If you made longer fins around the cooler, then cut slots the length of the cooler into the fins, that MIGHT help you, however I'm only guessing since I've never tried to create a heat sink before.
