Those are awesome results.

However there seems to be a couple of questions from an engineering standpoint. If a M3 makes 300 hp and they have different stronger cranks and rods, yet on Google there are accounts of bottom end failure with no modifications. And since a stock 325 is only 184 hp from the factory. Engineers don't make cranks and rods to handle the exact hp they're rated at, they usually engineer over the initial hp and torque for reliability sake however much they are ok'd to do so.
It seems then that 274 hp could be dangerously close to the limits of the rods if not the crank on a M54B25.
Does anyone have any knowledge if the stock 325 crank and rods have been used in GT class racing? And how much horsepower they can take?
Anyone have any knowledge of how many miles this kit has been driven on a
