Heres some Pics of water cooled, Some guy use to sell them on E-bay,

is that on your truck ?

That's pretty trick, and a sweet little radiator. Nice system!

Steven- yes, I meant it would be far too large for the truck.

ya thats kinda what i thought just wasnt sure though man havn a rad would be awsome is the guy still sellin them on ebay?

No not mine, I just remembered a thread on lstcentral that had some pics......

oh [&:]

you could probly fit a marine head in place of a truck head or would it be better to just get a marine engine because i dont know much about the power on them and if it would be a better engine than i have right now

wow a lot of desput on that forum but if you had a rad thats a good size and had a fan blowing on it i wouldnt doubt if it worked and water is a much better way to cool things anyway

what do you guys think of the cen 7.7 engine the one witht he black head cuz thats what im bidding on i like the fact that it doesnt scream but has a more bigger 2 stroke sound to it like a snowmobile

watercooling on our vehicles is a novel idea.. lemme go into a bit more detail here..

boats use watercooling .. they do so by picking up fresh water from there lake pond river ect.. and running it through the head.. then passing it BACK into the tributary

this poses a problem here.... on a 1-1 vehicle we use a thermostat.. for the purpose of SLOWING the water down to keep the waters temp at bay and allow it to cool the engine better by drawing away more heat .. if you remove the thermostat from your 1-1 car.. it will start to overheat because the water isnt in the radiator long enough.... the system shown above doesnt do that.. its using a fairly high speed pump thats going to cycle the water at a rate that it wont be in the radiator long enough to cool it off.. to work effectively youll need to slow the pump.. or create that check point for the water to be in the radiator long enough to actually cool it off

if this could be accomplished and a high speed system that would create the check point for a few seconds at a time to allow the water to properly cool off before returning to the head then it could work great.. but then we run into the issues of cartwheels.. frontal impacts and such.. and a metal radiator

so again back to square one.. our engines are best suited with an oversized cooling head to keep the temps at bay.. unless your using the vehicle for a pure show piece.. its just not worthwhile

Oh ya that engine is a blast, with 5hp u cant go wrong! here is one of my friends vid!

thanks ya i like the bigger engines because they dobnt have to rev so high to make power and they sound better i think

That is exactly the reason I like larger engines too. I heard a .90" four-stroke through a homemade muffler and exhaust pipe, and it sounded very realistic.

ya thats axactly what im lookin for is the deeper sound to get it away from the high pitch scream cuz im sick of it now i used to have a rc10gt and it did enough of that

and i was originaly going to put in a four stroke on my truck but decided to stick with the two strokes

if you use too big an engine you will kill your tranny and difs..... with the 4.6 the MGT come with my brother stripped our the 2 speed pinion gear...during break in! this was yesterday on tank 4

i think your running to hard for break in then

so u get the new motor yet?

no but i finally won the auction on sunday then he shipped it monday he said its going to come some time this week so im looking forward to it and ill keep you guys posted when i get it and put up some vids to and pics cuz i cant wait to see the over sized thing sitin in my little mgt

wat did u win the gst 7.7 engine or the pro 70bx?

The gst engine is huge, its like an inch or so samller than a cd!

i won the gst 7.7, lol what part is as big as a cd?

In side the black area, the head is like 3-4inches big

LOL wow it just keeps gettin better and better i cant wait to see it!!!

Take this advice from a long time CEN customer.DO NOT BUY THAT ENGINE.not only that engine but all CEN engines have a tendency to overheat.I dont care what anyone else says,their customer service is not that GREAT.I send them back a new motor,under warranty for overhaeting issues and they refused to replace.Tried to make me look stupid.
