I was thinking that also..

I battled with the same scenario. I could've had my p1 rebuilt into a D1 for about $1300. But for me I decided on the mp122hh. The Radix and the procharger are like night and day IMHO. The Magnuson makes more power "under the curve" without a doubt. Mine is also a daily driver though and I like that instant boost. I coulda saved a ton goin with a D1, but I never woulda been happy.

 

for your goals the di without a doubt, imo radix is the 112 and is undersized for that motor and also imo are more for daily driven reliable vehicles. if this isnt a dd and you want power the centri is the way to go . just pulley down and hang on . on my vortech i can make boost on laucnh and once its in boost its gone.
