Hap is (was) I believe..Although I think his is not an 'off the shelf' model..
Experienced it in the passenger seat a few times and could have used a diaper (sorry about the stain Hap).. ;-)
I'd e-mail him if he doesn't respond to this...

OOh, OOh, I know the answer!!!
I have run the GT35R before I was stroked and after. The GT35R I ran was a one-off. It had a .82 A/R turbine wheel but had a .63 A/R turbine housing that had been machined to accept the .63 wheel. Jim Latour of the old TEC had the required Haas equipment that allowed him to trace the outline of the wheel and set the clearance parameters he specced and then machine the housing. Anyway, this turbo really rocked. Maybe too well. I had compressor surge issues because the compressor would spool with too much flow before the engine was up to speed. Too much air trying to shove itself down the throat of an engine unable to digest it results in surge issues. This was vey apparent if you did not down shift before hitting the go pedal and was especially problematic when running up I-70 to Evahboost from Denver. On offline launches and in the proper gear, there weren't any issues except for the possibility of losing your license.
Since I knew that I would one day go with a stroker, i was willing to put up with the minor inconvenience of having to drive the car instead of the car driving me. With the stroker things improved dramatically and the surging was only apparent when the engine was under a heavy load.
My advise would be for a non-stroked motor and if you stay with the SQ mani, stay with a .82 A/R GT30R. Dave Dawson is running a tubular mani and a GT30R and has run a .63 and .82. He had surge issues with the .63 but they went away with the .82. If there is a chance you could someday go with a stroker, I'd go with a GT 35R .63 A/R or a .82 with a .63 housing. I am going with a new Innovative F2 bb turbo that will be good for 750hp. The GT35R I had was only good for 600hp. The reason for the switch is my new Big Valve, Big Cam Head (BVBCH). This will alow much more flow and the larger turbo just fits. If you're interested, that custom .63 housing and a polished compressor housing are available.
Hap, wit dakine turbo info not from Evahboost, Maguire
