Thanks Dr.Turbo, Will it drop off like a rock after 5500 because of the smaller T4 housing?

Yup...thats half of it, plus the GT42 cast compressor wheel kind of stinks.

OP, sounds like you need to call Forced Inductions for an upgrade.

I've seen it go ~ 740 RWHP on 370 CI thru a 4L80E. For some reason peaked ~ 6300RPM. 215/114 cam. Setup did have a really trick set of turbo headers.

Alright, I have been wanting to go with a BW but I think for now in my 2700-2800lb car 600-700ish will be more than enought for low 9's if I can get it to hook. Worst case I'll run it over the summer and if I dont like it I can upgrade to something a little bigger and better designed.
Stock48- If you have seen 740~ rwhp thru a 4L80 I think I should be able to make a little more through my T-56 and very light drivetrain setup. My car went low 11's @ 125mph on 422rwhp... And it probably had high 10's with some more practice. I only took it to the track once.
