Well the fist test did not go exactly like I wanted but here are the results.
The truck is a 97 auto ( 91% DTT with valve body mods as well ) PDR 370's and a PDR pump that flows about 330 cc's. With the 40 it ran 1500 degrees at 43 lbs.
Now for the Phat shaft 66 super, it seems to spool pretty good but not as fast as the PDR 40 which I expected. Once it starts to spool it does so very well. It runs right at 50lbs of boost at 1425 degrees. Now for the not so good news it has some pretty mean compressor surge at 18 to 23 lbs of boost and and at high boost if you move the throttle around it will surge as well.
I was warned in advance that they didn't have much data with this turbo on a 12 valve so these results hopefully will give them something to work with. So far I am very happy with the customer support and on time delivery of parts from Industrial injection, when they say something will be shipped on a certain date it was shipped and that is all you can ask for IMO.
I hope the here back from Shane today with the next version we will be trying.
