Crank and rod limits

Hello All,

Since racing season is over for me my brain is turning thinking about building another motor with more horse power. And that brought me to the first question : How much Torque/Horsepower can a stock welded crank and stock rods take??  Im thinking the motor will end up 130-150 horse range.

A good stock welded crank is tough as old boots and will easily cope with your projected HP.
I'm running a car tire Z1075 250hp turbo funny bike and the stock welded crank copes just fine.
