I was talking to Charper on here, and realized I still needed to port match my housing. Was running out of time before my tune date and just slipped my mind... But anyways as we were talking about, that should also free up a good bit of flow. Excited to see the numbers/power curve after that. Also I know for a fact what my boost levels were. I was overboosting to about 19 pounds which activated my boost cut so I had to data log back and forth with Jeff till he got it tuned out and back to the targeted 13 psi.

Isn't the S257 Compressor and Turbine wheels the same as the EFR7670? My 7670 made 480's at 13-14 PSI, and is making mid 500s on 16-17 PSI, still on Pump 93.

SXE uses the EFR compressor wheel.

2 "completely different" turbos, but with virtually identical compressor mapping and air flow rates. They're very comparable for power numbers. Reliability and longevity is a different story, considering the SXE is JB with no water cooling.

upon a few quick Google searches, the EVO community even prefers the SXEs over EFRs because of the smaller packaging but keeping same output.

His SXE dyno graph is virtually identical to the FullRace EFR turbo kits out there.
