What kind of damage does a leaned out motor have?
 

If there is NO detination, and you just run the motor lean to till blows, what kind of damage happens.

Example:
-Break apex seal
-Apex seal break, sending them into the turbo
-Distroy the Housings
- ETC.

Does anybody have any experiance with this happening to them????? I'm curious
to know what happens????

It won't blow without the detonation. It will just stumble and stop making power if you lean it out enough (and don't detonate).

-Max

Your EGTs will also be hotter, so perhaps some heat related issues. But like Max said, it's the detonation that crushes your balls.

I have herd of people warping internal engine parts from extremely high combustion temperatures (resulting from a lean mixture). I think this was talked about in conjunction with the so-called "buttplug" invention. They were able to tune the cars so lean that they started having problems with deforming rotors and housings. I never saw it in person so don't quote me on it, but I'm guessing thats the type of damage you would see if by the grace of god you somehow got there without pre-ignition.
