Thanks for the reply about the D-1SC! You have definately provided some solid real-world experience that will assist me in making my decision between the P-1 and D-1.
I had been leaning towards the D-1 since the beginning due the things that you mentioned above (double bearings, stronger internals, etc.). I'll take 5lbs of boost at 3000 rpms! That is impressive.
Thanks again for the insigthful reply.
