I'm interested in running in an almost "anything goes" class.
If I de-stroke a Fiat 1438 crankshaft .5mm, with the 1.4 multiplier applied when using a turbocharger, I can run in the under 2 liter group.
My question is, how much horsepower can a properly preped 1438 cranksaft withstand?

I cannot remember if it's forged or cast, you better publish a photo of if, showing the crank web.
