HDI's make the same power with alot less stress. They have lower compression to start with, and you run much less boost to make the same power, therefore overall cylinder pressures are much lower....and this is what kills them through bending the rods over time and eventually letting go. Ive pulled many high boost xuds apart and found bent rods, just the first stage of it before they evetually give in and brake.
The first thing anyone will notice when moving from IDI to DI, is how much "free'er" the motor is, can just run 20psi and make the same power levels as the XUD is STRUGGLING to make reliability at 40psi +, this is why xuds constantly spit rods.
