The turbo combo is a custom Race billet S475/87mm 1.0ar fed by a pair of TCTBMW S475/87mm 1.0 stainless vband. This combo has already made 1763Hp 2450+ftlbs on my engine dyno so it should get Brett his goal of mid 8's as long as trany and traction play nice for him. It is an amazing setup and should be a handful for Brett to drive! Spool up is quick and easy and a baby tune will net 850hp range with a flat curve from 2400rpm until you let off the throttle. His new motor is built to run into the 6K+ rpm range so he needs all the air he can get!:thumb:
Those are some pretty lofty goals.

Thanks for all the complements guys. My goal is to have it running early this week and and put a few miles on it then test Friday night with Mark.
With those numbers, I'm not sure I would change anything. You have a 3.3:1 pressure ratio on the atmosphere turbos and 2.7:1 on the high pressure turbo, and drive to boost ratio is .8:1. I don't see what benefit you would get from a gate.Made it to Indy to race today. Converter took a shit first pass but I got some good data logs before it went out. I think I need to add a wastegate to the system. Atmosphere chargers put out 34psi, total boost was 120psi and drive pressure was 96psi. I need to add a gate to the exh housing of the high press charger or add one gate to each manifold. I know nothing about gates so does anyone have a recommendation of what size and brand?
Thanks
