Heat or Lack of Oil?

[foolio]

What is the #1 reason for the premature engine failure? If some how I can maintain low temp with leaner carb setting will this in anyway cause engine wear due to lack of sufficient lubrication? Does heat play crucial role in excessive engine wear? If so why? I'm currently experimenting with cooler running head design other than conventional methods. Any comment or suggestions will be appreciated and please do not bag on each others opinions. I'll be the sole dogger on that... HeHe http://www.traxxas.com/ubb/smile.gif

i will try and keep my post short if i can, i have a habbit of writing some long ones on the performance car boards.

its a combination of the 2, basicly you need oil to keep everything lubed so the leaner the setting the less oil you have since the oil is carried in the fuel. so the leaner the setting the less lubricant you have but on top of that high engine temps will cause oil like castor oil to break down and vanish making the little oil that is in the engine less effective. natural oils like castor oil are more prone to break down to begin with that is why they add synthetic oils which have a higher resistance to heat and break down, but they are less effective at burning and carring away heat from the engine.

also lean settings and high engine temps can cause detonation which is a whole different arena of motor damage then simple lubrication.

Hey Masher, that's my thoughts exactly J/K. I was wondering about that now I just wonder. If I can maintain the low heat and add more oil to the fuel mixture wouldn't that compensate for the lack of lubrication?

yeah that should help but then how much castor and how much synthetic do you add? its a good question and what kind of synthetic do you add? of course you would also need to use a slightly higher nitro percentage to since you will be deluting it with oils so by volume it would have a lower nitro percentage.

all of these questions have been researched by the nitro fuel manufacturers a long time ago so you have a starting point but of course you run the risk of ruining engines at a slightly higher then normal rate when you start trying to re-engineer the fuel and engine. i guess it will depend on how lean you are trying to run the motor as to how much each aspect is going to affect motor life and performance.
