It was at 30 psi and it is the same modification to the rods to get the 2g pistons on the 6 bolt rods.

Here is the dyno sheet, wouldn't let me upload it before.

Very nice man. I'm about to pick up a S256. I'm shooting for about 450.

Maybe Shane can chime in, but that appears to spool similar to a 35r sized turbo.
That powerband is sweet congrats man, go run some 10s!!

Ya it may be a little slower than usual due to the t4 housing it is in, it's in a .84 AR divided t4 housing. Don't ask me why but the previous owner had it made for it.

Damn that sucks. I know a friend of mine uses a mitsu flanged S259

Ya it does suck but I guess I know the housing wont choke the turbo down. I am also thinking about swapping an HX40 pro with a divided t4 housing and see how they compare.

I was thinking about this and found an old dyno plot from shane/mara's 'project salt collector'

Overlay shows mara's SC61 outspooling this thing but the BW turbo kicks butt up top!

Thanks for the overlay!!! Yes I bet the t4 housing is slowing the spool down alot but helps out with the higher RPM as it doesn't choke out. I think if it had the smaller housing, it wouldn't be able to hold that power all the way to 9k like it does.
