I've been running my m112/v6 since July. I've put over 8k miles on it to date as my daily driver. In the summer I was getting max boost of between 5-6psi with my pulley config. Lately I'm getting 7psi with the cooler/drier air. All has been fine at this level. But I'm wondering, how strong is the crank snout on these 3.8s? Right now I calculated at 6k rpms, under full boost, my eaton's demanding ~45hp. One of my concerns is at such time I crank the boost up, am I going to twist the end of the crank off. SC cranks are forged. But then my option of going to 4.2 liters may not be wise. Positive displacement blowers are less forgiving on an engine's rotating assembly because of the little to no lag time that max boost can occure. What are the options of getting a stronger crank?
