FYI the spec you gave of a 76mm inducer and 102mm exducer(major) diameter are for a T-76 compressor wheel. If he was using a T76 then all the numbers you mentioned fall into line. Heres the compressor map for a T76 compressor: Looking at that if that is what he actually had I could believe 750+ at 23 PSI. And thats well within the efficiency map of that compressor with an S/Q trim sure. But definitely not a 62-1 compressor.

Okay screw it. I am gonna go to the shop this weekend and fab up a quick charge pipe and put one of my TC76MPS turbo's on the car. Probably end up runnig a straight down pipe off the turbo for simplicity's sake. It is gonna run on my 8.5:1 370 cube engine with ported and polished 6.0L heads, a Speed Inc TU1 cam, and LS6 intake and TB.
It wont be for a couple weeks or so. I still have to get the rest of the car put together but I will get it done, get it on the dyno, and get the graph posted. End of story, we are gonna see what this turbo is capable of. If I dont like the results I will order a PT88.

forcedfed who the hell knows for sure what turbo's we have?? I just gave orders for my turbo guy to open up the turbo and spec the wheel he is doing it this evening. Stay tuned for the real deal.
Dr Turbo and Jz if forcedfed and I do not have the true TC76MPS how do we go about fixing this MAJOR problem? Where do we send the turbo for a correct replacement???
