> As an aside, the most powerful F1 engine ever put on the track was made by modifying the little 4-banger m10 found in the BMW 2002. Fun fact.

Supposedly BMW lacked a dyno that went high enough so it's an educated guess what the actual hp was, but definitely over 1,300hp... from a 4-cylinder (turbo charged, and only lasted a few laps, but still) engine!
