Amazing. In the first pic I wondered if it was even a dale motor.
Untold.
The Halls Of Destruction
That baby let go at WOT at the rev limiter during a race. Ive had a few engines blow chunks in my time but this one actually sounded like a bomb went off with a smoke cloud and flying debris to boot. The starter went through the radiator before flying out to the side and dangled from the battery cable.
That was the first 70 horse engine . Nitrous shock loads caused the pin to crack right in the center so the rod end had to hold it all together till it fatigued and broke off the end of the rod. As a testament to the strength of the crank a new rod was installed and it has been running ever since.

I figured Id put these where they belong. From the this is why we used tool steel wrist pins for nitrous lesson.
Been there done that, I even lose the fan and radiator. The rod stopped at the tranny. It was even a 2.2 crank.

This is whack . I wonder how long it was running this way. The missing pieces were long gone and the broken out areas were sooty so it was running happily with exposed rings.LOL
It was a stock wiseco piston . The crank bearing was ripsawing .

I have had that happen with those exact same pistons but to one side only... the piece exited doing no damage however it turned into a mosquito fogger right away as far as I know.
Yes this engine was kind of a slight disapointment . It has extremely low hours on it and yet the crank is already junk . Its an old style cable case with machined rod . It had a bunch of goodies likea bike basket , metal oil pump gears ,aluminum cam cover and fx400 cams in perfect condition but I was banking on the bottom end to be good. The case is also the X5 marked dark gray one.
