Most Horsepower Stock M156 Block Can Handle
I'm new to the group and have a 2014 C63 owner. My dad and I are going to build our car.
I see supercharging is the most popular way to get power. But I cant find anything via searching
on how much the M156 block can actually handle before failure.
Thanks for the input and I will search the forum for all the information I can get on this car.

If the C63 has the forged internals (P31) it will fair a bit better. The thing that I see fail most from those who supercharge is the transmission (slipping gears). Of course every car is different, and some get lucky if they don't go super aggressive on power.
Let's talk limits of the stock bottom end
