i cant recall the specs on the turbo, all i know is it is long awaited!
im gonna try to have numbers from it dyno/track by the end of november.
heads are off the car at all pro right now.
a T6 can't fit on my turbo system.. as big as this one looks if you ever see a full frame turbo they are significantly larger. lots of guys start out with have t4 kits and end up needing to push it to the max, this would be that type of situation

From what I understand This T4 91mm will reach full boost by 4000rpm. That is very aggressive for a turbo of this nature. We are still tossing around the idea of using this turbo on a 9.5:1 347ci setup in my new shop car and playing around with some 275 Radial stuff.
I still think Twin ProMod 71's would be more fun on a 3xxci ERL Based engine...

You need the new GTX-42 billet 71's. We are working on getting them done for release next month. Will make 100hp more then the current 70 and 71's.

The GT47 turbine wheel is actually smaller then the current PT88 turbine wheel. The turbine wheel used in the 91 is actually the same size turbine as the PT88.

i think i would like a housing sent to me machined down to a 4" inlet instead of machined up and out to a 5" inlet.
if i cant get that done then i need a 4" to 5" 90* elbow out of somethign that wont collapse.. and i need a 3.5" to 3" transition
phil i ran into some valve trouble in memphis. heads are at all pro figuring out whats up with them.
running out of time for sure.
