USP Motorsports 996TT: Engine build thread
#46
It helps but one time I tried to figure the duty cycle its 110-120% on 1.1 bar
And I'm using the 5bar FPR also
I was data logging my car that time.

There is a melting point temp and a pasty point that is lower then the melting point. The pasty point is where the piston will "skid" or deposit material on the cylinder. lwfw has nothing to do with rev limit, it will let the motor rev quicker do to less mass. That's all nothing more or magical about it. The sharp rod angles increase the speed of which the piston travels. I can break out some books on this and put up the formulas for this. I can tell you it has a lot to do when you stroke motors you raise the pin height rather then shorten the rod do to the piston speed is increased when the rod is short compared to the stroke. Our motors have short rods do to the fact that they lay flat and need to fit where they do. There is a lot of compromise in this motor as I have stated many times before. Anyone who thinks they will spin one of these motors up to 10k with the stock rod length and materials used today is dreaming a dream. They can use titanium for the entire valve train, hell for the entire motor for that fact.
