Unlike port injection DI engines have a very short time to inject fuel into the cylinders so they typically run around 2,200 psi fuel pressure at injection. Yes, 2,200 - not a typo. Couple that with an already high compression engine and internal pressures get stupid but that's how you make 323hp from a tiny 217 cubic inches.
There are soot and fuel dilution issues too but it leads too oil viscosity failure.
