Default Supercharging take 2 - if the engine is not detonating, is a supercharger still hard on the motor

The way I see it, the more effective compression you run, the more of a beating the pistons and rings are taking (not to mention every other part connecting the driveline).

But, am I wrong? If there is no detonation, is supercharging a motor compeltely fine? The 996 guys are arguing with me again that a 6psi blower won't shorten engine life AT ALL on an 11.3:1 motor...

Default Probably won't last 300k, puts more stress on bearings and rings and such.

But then again, these are probably the same guys that put red loctite on rod bolts to keep a motor together.

Default First why do you care? If they think they are right let them spend their money and blow the **** up

Second I would not turbo/supercharge anything with a compression ratio higher then 10:1.
And I would make sure I have a really good EMS and some really good gas.

And use some common sence. Obviouly anything you do that is putting more strain or stress on the motor will shorten its life no matter if it detonates or not.

If the motor was built for N/A and you go and charge it don't ya think it is going to put some stress on that motor?

Default I dont know if it will shorten engine life, but it certainly puts it under more stress

higher pressure = higher stress (DUH)

the life component depends on the factor of safety (fudge factor) that the engineers built into the motor.

Default

I care because they are telling people considering SC'ing that it has no adverse effects

Default Increasing engine output by as little as 5% increases the wear on parts...

There is no doubt that a blower will increase the wear as well as fatigue the load bearing parts quicker.
