Default 408/turbo GTO, how much RWHP do you think?

Specs on the car:
408ci 8.9:1cr
Stock ported heads/LS7 cam
Rear mount PT80 turbo @ 14.5psi
Nasty Performance Stage 3 fuel system/60lbs Injectors

The car on a stock longblock LS2 with a GT70 turbo @ 11psi made 640rwhp. On the new setup I would love to see north of 800, but honestly I have no clue what she is gunna do.

How much power do you think it is gunna make at the wheels?
