pt pro mod 88

Anyone using one of these turbos?
How do they compare to the gt47-88?

It is my understanding that they have been tested with favorable results.
I am not sure how much of a response you are going to get.
 
Is it a billet wheel and any hp gain over the gt4788

It should definately pick up power over the 47/88 just due to the turbine side alone. As far as the billet wheel..........I'm not convinced they are better in a lower boost combination. My car will make 27lbs of boost. I tested a billet 94mm against a cast 94mm back to back with no noticeable difference. They made the same boost, same 60' with the same et and mph. Maybe in a high boost situation like above 35-36#, the billet wheel could be better.
 
It looked like a v band clamp on turbine inlet side.
I was told they are lighter as well about 40lbs.
Is the housing for the gt55 a 5 inch outlet

I think they are 5" outlet. I haven't seen them other than what was on display at PRI.
