What really kills an engine
I was just thinking after reading losi's claim about the new 8t2.0 body helping the engine run cooler, doe the temperature kill the enigne or is it the lack of lubrication, i know they go hand in hand in a way, but when you say that just allowing more air to run over the engine head will cool it, meaning you can lean it out more, will it not just wear out faster, because of the lack of lubrication?
just something i was thinking???

Personally, I think there are two ways to kill an engine. One is not running it hot enough and eating the pinch. The other is running it too hot and not letting it have enough lubrication. I think there is an optimal temp to run these engines that lets the pinch open up and still gives it lube.

That can also be a factor but if you use a good air filter and clean it dirt shouldn't be a problem. I have had 2 engines blow up(not just wear out) and that was because of bearings. one of those things I learned from and now put ceramics in all my engines right after break-in.

there are so many variables that kill an engine thats why it is very important to keep your engine in tip top shape , keep a very clean and well sealed air filter system , do not run too cool or too hot and use a high quality fuel such as byrons with at least 11% oil for regular everyday running and lowest of 9% for those "i gotta go faster!" race days

when he says bearings he is referring to the bearings in the motor... such as the front bearing and the rear bearing..

The way you should read Losi's claim on the body is you can run a leaner needle provided you run a fuel with high oil content (12%-15%) OR you can run a higher nitro percentage on a regular setting -if compression & oil % are constant the higher nitro will make the engine run hotter

Dirt, Dirt, too hot and lean, mostly what most people have said but mainly dirt. I run my motors an average temp 220-250 deg. usually an 11 % oil content fuel. My son runs his motors for max power and fuel mileage and less oil content fuel for better runtime. (yeah he's much faster than me) Doesn't matter what brand motor we are running, his shows more sign of wear than mine. If you want your motors to last you can't push them, and keep up on the filter maint. I have seen a few rear bearings go out and the pieces of bearings go through the motor and scratch the sleeve. If I run a double sealed front bearing I like to pull it out every gallon or so and pull the seals and clean it and regrease it. They do not flush clean like a one seal bearing but the dirt doesn't go into the motor either.
Or you could just get a body that looks like a Catfish and your motors will last longer too.
