I feel like 300-350 crank is the sweet spot for still having fun and easy to maneuver in traffic. Anything more is purely for shenanigans.

This is with respect to a car weighing ~3500lbs. or so. Adding weight changes the equation accordingly for a heavier/bigger car.

I absolutely cannot wait for this Spring when I finally do some power mods to the 328 - that's all she's missing. I love my RWD MT 328, it weighs just 3330 lbs. and with another 50-70 HP crank I think it will be fantastic. 280-300 HP in this car would be an absolute blast to drive. It won't win any races, but the driver engagement and feel will be the next best thing since the E36 M3 for a 3.0L BMW straight 6.

TL;DR: 100hp/tonne is just right in my opinion.
