Default looking for 18g-xt examples

Well guys, finally time for me to post on this I guess. I've been looking for some Blouch 18g-XT examples on the STi.

I currently have this turbo, and dyno'd to 347whp on EFI Logics' Mustang dyno on E85. Mods included a built bottom end, 264 cams, 1mm oversize valves, APS 70mm intake, and APS FMIC. Stock exhaust manifold. My fuel injectors (Power Enterprise 850cc) were running uncomfortably high duty cycles, so I switched back to pump gas.

I am now ready to switch back to E85, about to do an ID1000 top feed conversion and AEM 320lph E85 pump. I have also added GrimmSpeed PnP manifold, high-flow crosspipe, and up-pipe with TiAL 38mm external wastegate, and switched to a 3.15" Tomei exhaust and lightweight crankshaft pulley from GrimmSpeed.

I'm just trying to get an idea of what similar setups have done on E85, so I have an idea of what to expect and can determine a target boost pressure. Primary use of the car is road course and autocross.

Can't seem to find any examples of this turbo on an STi with E85. Anyone point me in the right direction?

I'm off to the E85 army thread!
