I am not one to experiment, but this I am going to have to do. I took apart a computer that was given to me by a friend. I was dismatling the thing a I happened upon a Peltier Cooling system. I looked it up on the internet, and found out that it was a 8.1 volt system. I hooked it up to a 9v batter, and damn that thing about gave me frost-bite. I took apart the peltier system (took off the radiator, and fan). Now it is just a little plate about 1/2" high and 1" square.

What would you guys say to it running off a pack of 9v's cooling a nitro engine, either from the top, or getting some 1/4"square peltier plates, and placing them all around the engine?
What are the advantages of running a cooler engine? :wtf:

Anyone tried this? or is this just a goofy idea?:loser:
 
sounds good dude. try it and keep up posted on what happened. i would suggest to try with a crappy used engine though. i was thinking about putting a fan that blows air from the side of the heat sink, so that it will blow the heat away. not sure how i'm gonna go that yet.....let me know what is up..thanks
 
I found a page that sells round, peltiers, they have the middle cut outs, doughnuts, what about one of those for the top of the engine heatsink, and the 1/4" ones on the crank case?
 
Well if you tune your motor correct, there is no cooling issues.., but id like so see what ya come up with..
 
it just mean that you can tune your engine super lean and not worry about it heating up.....
 
UMMM not really, leaning it out too much and your taking away lubrication, and the weight of the extra batteries/peltiers, will prob cancel out any "performance" you will get from FROM GOING A TAD LEANER

BEWARE! This thinking is WRONG! Heat isnt what breaks a nitro engine when it is running lean, friction is. When an engine runs excessivly lean, the oil content dissapears, which causes friction and destroys an engine. The byproduct of friction is heat - which we use as a determaining factor to tell if running too lean. Want proof? Run your engine in sub freezing temps - see what happens when you lean it all the way out to 280 degrees.
 
hey id do it dude i dont no exactlry what you doin but i alreadyn thbought about taking out a cpu fan and putting in my car cuz it just runs so hot it wont fix so id try it it canrt hurt blow air on head blow away hot air? only guna help I'm gunna tke apart comp right now so go for it dude!, if it brakes fix it!
 
There is nothing that says you can't still use your idea. The caution comes in play when you say you can run super lean. Granted using these cooling plates will make it a little harder to determine exactly where your "too lean" point is, but then again most people think the the new TRAXXAS 2.5 is a great engine (no matter how hot it runs).

Keep you engine tuned the way you have it now. Apply the plates, and see what performance gain, if any, you get. If no gain, then adjust the tuning in small steps. Depending on the engine, the manufacturer directions most likely detail where you should not set the needles (ie never run the engine with the HSN set below this many turns).

Experimentation leads to innovation...and sometimes that is just as much fun.
 
You might be able to try your idea on a helicopter engine installed in a car or truck. Helo engines are big cc high pony engines, in a maxx or savage it could be useful.
