this is how to cool a motor(sorry for the pics, i didnt have a digi-cam so i got the pics from radioshack)

either method is good

I've never found a heatsink to "trap" heat
it pulls the heat away from the engine and out towards the thin fingers where it can cool off.

drilling holes as you suggested is good, it will allow to heat sink to be more efficent

usually heatsinks do that, but xmod heatsinks dont do too well

one reason I dont use mine

to much weight for the little help of removing heat

mine gets to hot anyways, burns wires clean off the engine almost everytime.

I think the point of the metal "heatsink" is to keep the plastic one from melting into a large yellow puddle of goo.

i've read that polishing the heatsink will make it more efficient as far as dissapating heat goes.

Yes. To a certain extend. polishing removes any dirt debris or stains from the surface and thus allows the heatsinks to work better.
If you paint your heatsink it will be like dirt on it. reducing thermal efficiency. Unless u are using special paint or something

hey about the cuting out the grills i would also drill curcular holes in the back bumper too let the heat and excess air out. and it looks prudy cool to me i seen it on a real skyline

about the dilling holes in the back, if you could somehow avoid that by making an exhaust system. like having a small pipe in the back bumper and on to the chassis. that would be pretty cool.

If u drill holes in the bumper for the hot air to escape, it will not work. It might cause your bumper to become very weak and maybe air drag also. Wind does not escape effectively in this kind of setting. maybe raising the rear like removing the bumper can help the air to escape. I would not recommend drilling too much holes in the body. You guys should put a layer of hot melt glue on the inside of the body to reinforce it.

Why don't you just remove the side windows? It's not that bad if you cut it right.

ben1112 · #12 12-19-2004, 08:32 PM

That could have been feasible. But question is how does the air escape? IMO i think it's quite an awkward way for the air to travel, so may i suggest that you guys drill a large hole in the front windscreen? It is done in 1/10 gas cars so it might prove effective in smaller scales too. (and they look neater too)

No it's not good. One reason being that the air that enters thru the bumper has to travel pass alot off stuff before it reaches its destination. In this case it's the front of the chassis. It will work in 1:1 because it's where the engine is located. But not in 1/28. Below is my suggestion.
