KKell83 said:is the gt40-88spl is considered as a DBB why is it cheaper then the basic gt40-88???
I'm just trying to get near 450-480rwhp (pump) and higher alot higher with 110 lol.
I dont know if this has ever been done, but this turbo should be pretty good to make that forum of power. Yet I'm always wondering if it well spool good.. I want something with hit 20psi 4k. lower the better but could also hold the boost once I get head work.

Howard from NY made 562whp with 22psi (21.5 I think) at 4500rpm with a gt4088
