To much for a crankshaft

[AirAg]

Has anyone ever heard of breaking a crankshaft on a 4 cylinder cont. GPU. I am wanting to rebuild that spare I have with dual mags and GITSU 520's. Just wondering if this could be too much for that little 4 banger.

Thanks,
Brent

The PE90's have a pretty stout crank. My friend of mine eventually broke one but this was a 11:1 motor turning 3400rpm's with alot of nitrous running through it. On a 10 1/2ft fulldeck this boat has humbled many 6 cylinder boats in a drag race.

They are a good strong cranks an handle 520 stuff just fine go ahead a build it

But like everything it is possible to snap one. I seen a 470 conversion come to me that snapped a crank but that was a prop issue
