How Does The F56 JCW Do On A Dyno?

Here are MotoringFile's findings as explained by Pedro at MotoringFun:
Of course it goes without saying that dyno results need to be carefully scrutinized. Everything can be a factor from dyno to weather to everything in between. Yet if these numbers are correct, this MCW with the JCW Tuning kit is putting down 206.53 hp and 236.99 ft-lbs at the wheel. Thus if we assume the typical 12% drive train loss we’d get something pretty impressive. Power at the Crank: Horsepower: 231.31 bhp / Torque: 267.80 ft-lbs. We’ll let him (Pedro) explain:

"Based on these numbers, I would say that MINI is probably quite conservative in their John Cooper Works power ratings of 228bhp and 236 ft/lbs of torque, especially considering that with just the JCW Tuning Kit, Clark (the name of his MCS) has exceeded both the published horsepower and torque ratings of the factory JCW. I do hope to have someone else with their F56 Cooper S and JCW Tuning Kit come to the October dyno day so we can have another car to compare against to see if this is the norm or if Clark is just “SuperMINI” after all."
