Evo X bolt on Garrett GT30R turbos
looks promising... there is he 3076R with .94 and 3071R in the smaller hotside... In contrast to what many people think, I feel the 3076R will still need to see 25psi to make big numbers... the 3071R is obviously going to be a little more responsive...
we use the 3071R cart on subarus and its a torque monster....
we are excited to be working with garrett on this.

You'll definitely need to boost up to ~24-25psi to make some 'big' numbers. My estimation is about 425-450whp on pump with all the typical bolt-ons plus cams. This is based on AMS making 450whp on a GT35 with no cams.
consider a standard 35R evo 8/9 makes around 400wp on our dyno on pump, and the torque SUCKS!!!
we will see.... i love the X and im confident great things will come from the platform.

Maybe on Buschur's.... but any dyno that shows about 250whp stock, I think the 3076 will do 425-450whp. Buschur hit just over 400whp with the Blouch turbo, so I think 425whp seems quite possible on his with the 3076. I guess we'll find out at some point!
CBRD, 350 pump and 420 race on your dyno would be enough for me to start saving pennies for one of these suckers.
I'd hope for more, but hotside and exit using the stock DP and the internal gate makes me think power will be less than what I want it to be.

I'm not going to mess with the internals of mine for a while since I think 500-550 crank HP is going to be plenty, but I bet someone will try and cram bigger wheels into this housing sooner or later as well. I'm still assembling the supporting mods for the turbo and due to some track days in late May I won't tackle the install until early June. Rest assurred I'll be posting full dyno plots and quarter mile numbers as soon as I get them.
The goal is 400 whp on STM's Mustang Dyno (reads similar to Buschur's heartbreaker) running 25-26 PSI boost on pump. Chances are I may still have to add cams, extrude honed intake manifold, and/or race gas at 29-30 PSI to do it but it will get done. :P

I'm going with a tubular exhaust manifold or ported/extrude honed manifold plus an O2/Downpipe combo to make sure flow in and out is as good as it can be. As for boost creep I would imagine that running 25-26 PSI it should be fine since you aren't trying to dump as much boost. Possibly there would be some creep if you tried to run the turbo at lower boost levels but with a high flow O2 or external dump it shouldn't climb past mid 20's, only one way to find out!
