Ok, so heres my idea. What if I put 2 tanks on my maxx. Bought a marine head for the 2.5 (if possible) and filled one of the tanks with water. Connect up the fuel lines and hey presto, water cooled 2.5. Would this work as I have no experience with rc boats.
Thanks :stupid:
 
that wouldnt be effective due to two major reasons. the first is that the water that cools the head in a marine engine is forced into the tubing by extreme water pressure just behind the prop. to get this to work in an rc car, not only would u have to have an extremely fast pump to push the water through, but u would also need some sort of way to cool it, as it would heat up incredibly fast once the vehicle was moving and the water storage area soaked up all the heat from the mill.

second - u would need a huge supply of water in order to keep enough going throught the head to keep it cool. something on the lines of a quart for every 5 minutes of run time. this would impractical and very very heavy. good thought though.
 
Cool idea, NA was proper in his explanation on why it wont work.

My question is why do you want to do this?
 
i have seen a guy on ebay that did it to his truck. he said that he did it so he could take his truck rock climbing. he had 2 tanks with one water and the other gas. then he had some wierd type if splitter for his fuel lines and all of this stuff. but it was pretty kool.
if i can find it i will post it.

you can get a pump system for the fuel lines which are used in airplanes so they can fly upside down.
 
Don't let them piss on your dreams. Sounds like a great idea however you will need something to move the water. The major difficulty you will find is weight and space. You'll probably need a hair more that a single fuel tank can provide to cool your engine. While a fuel tank filled with water will keep your engine cool, pumped into the engine head, after a short time the water in the tank will be as hot as the engine is running, maybe a few degrees cooler but nothing significant.

What you will need to keep your engine cool after the first few laps is some sort of home made radiator system. You could make a radiator using fuel line that say runs the entire length of the chassis and back, maybe more than once. Without installing a fan you will be dependent upon air cooling the line so running the line several times along the length of the chassis might be the best way to keep your engine cool.

Bear in mind it may take a few times to get the right combination worked out so watch your engine temp closely or you could burn up your engine. If your engine does get a little too hot do not cool it by pouring cold water onto it. Let us know how your little experiment works. Who knows, maybe you'll find the right combo and be able to sell this idea.
 
It has been done before. On a TRX .15. I'll see if I can find more info. But the guy retrofit his TRX with the marine head. Hooked up a Perry pump and also hand fabricated a small aluminum radiator to cool the water. He said it worked well and kept temps quite low. I'll see if I can find a link..
 
Fuel tubing won't absorb the heat like a metal would, you could have tons of fuel filters :D $200 in $3 Du-bro final filters :LoL:
 
I no this is a widly spread bad idea but I'm makin a custom tmaxx that will be supercharged and i want to liquid cool it i no its a bad idea every1 tells me but its sumthin i wana try idc i hav extra engines. But if any1 can find me sum info on it plzz let me no id appreciate it. I seen a nitro 4 tec dat was liquid cooled but I can't find it now. But let me no thnx Have a nice day

You know, I saw this same idea somewhere about just running/routing the fuel line the same way to help keep the temps down because of the back pressure/air pressure if you will, by making it longer helps to increase air flow. I just can't recall exactly where I saw it, if it was on here somewhere in one of the forums or if it was on youtube.
 
ok, just cause didn't see anyone mention it. In your house they use fins on a pipe to transfer the heat in a hot water system. I'm thinking something like a thick tranny line (copper) looped around the truck with little fins mounted on it. you would need a smaller res then. Still I think it wieght would come into play at some point. Of course they said that about dirt bikes 20 years ago. Liquid cooled definitely makes for a more stable temperature enviroment which is what we all would like for our fussy little motors....
 
good idea
instead of using water would it be possible to use radiator fluid from a car??

Just a thought
 
instead of using silicon fuel line to run it around for you coolant would be to use aluminum monster fuel line that you can get at www.rbinnovations.com that would help dissipate the heat better than standard fuel lines. Another thing is finding a head to use that will fit on to the engine unless you are going to make that yourself. Can't wait to see pics of it when done

the head is not the problem as there are plenty of marine engines out there, the problem is in being abe to get the coolant(water, antifreeze, etc) to dissipate the heat. the aluminim tubing is a great idea over the copper and if you cut down some house hot water heater fins that would help as well(kind of a home made radiator). If you ran a small gear off the drivetrain somewhere to power a pump..hmm..maybe off the spur gear. I'm sure that someone with access to a machine shop could make a tiny hydraulic stlye pump easy enough.
Anyone bored enough to run with any of this??
