What have you seen pushed through this housing? It would help to know as much of the specs as possible, like displacement, rpm, turbo specs, ect. Thanks for anything you can share.


EDIT: T6, 96mm turbine wheel

The ET calculator put mine at 1070hp with my FI485/96/1.15 T4. Im sure a whole lot more power could be made, my truck is underfueled for this charger at the moment. I shift around 5k RPM.
 
Curious what people have observed for gains, if any, switching to the 1.15 from the 1.32 in a compound setup?

I’m also curious about this , I’m lookin for a little faster spool from my s480 for towing purposes . Bullseye has a ss v band flanged 1.00 housing I’ve been eying for the 96 wheel
