Gotcha! I’m not sure, I know he does “tuning trips” to Canada now. When I got my car in I think he was in the thick of things. He may now not offer tuning in the states, not sure! What kind of power are you making with your setup? I feel mine takes awhile to spool up, but boy when it hits it doesn’t stop till you shift lol pulls hard all the way to redline.

450 on 12 lbs on a 257???? Seems a little odd.

Why is that? Just because the small frame turbo? I have the charts and dyno graph to back it up.

I did some checking, you def. have something confused. Every guy I know running the 257 is running north of 20 psi to get into the 400hp range. Even with a 1.22 ar housing.

holy crap that’s an awesome dyno graph. Really Making me want to switch up turbos now haha. For my goals the s362xse just isn’t needed is way to big. I want around 450 pump and gonna be mixing my own 100 octane gas so hopefully maybe hit 500ish. We will see. Thankyou for the info and dyno sheet

I first ran a .89 twinscroll. It was AMAZING as a daily driver. Thing made boost leaving the stop light, but the top end suffered as it just couldnt flow enough out the exhaust. I previously ran a 6262 and made 508hp @16psi. Never dyno'd the 257sxe, on the .89 housing I just adjusted the tune and was running 23psi im guessing it was in the neighborhood of 450hp. I wouldn't recommend it with a housing that small though
I’m also serioauly considing just sell this whole hot parts setup and going with a twin scroll s257. That .89 housing sounds awesome! Boosting from the stop light is the driving I want!. But gonna be drag racing the car. So maybe the bigger over 1.00AR housing would be better for me, still should spool way faster than the s362xse for sure . Borg housings are super cheap. Might just buy both lol. Thanks again for the reply.

theres a build thread on here with a guy with a s257sxe, he had a top mount T3 setup .70 AR on race gas he made 595whp. Pretty crazy.

I'm a little taken back on the numbers coming out these s200 Borgs on such little boost.

Id love a data log to see for my self lol seems a little high.
