High hp turbo help
 

Still running the stocker right now but i was just wondering for a 900+ hp streetish truck what kinda size/brand twins would work nice. But here is the catch, i want to run the smaller turbo as a single until I need/can afford twins. Im really tempted to get a 66mm silverbullet as a single but that would obviously be way too big in a twin setup. Then thought maybe get a 62mm SB cuz it would spool nice but then im lost on the large turbo?

Any help/criticism would be appreciated.

900+ on fuel? or on the juice

My personal goal was a 1000hp fuel only street truck. I realize my goal is somewhat "ambitious" and I have read enough forums on here to know it wont be cheap or easy but this is a long term project. I know that almost everybody on here will tell me it cant be done for a street truck but I still think it can be done. All that aside the direct answer to your question would be fuel only.

tripples would be my answer to your question than. A set I would love to try if I had the truck/money/time is ... Start with a 66/73/.9T4 off the manifold with one of sdx's spool flanges, along with a good size external gate, two 64/71/.9t4 atmosphere chargers feeding the 66 with a external gate on the header. Gonna be a fair amount of plumbing with the flange and gates but it should spool quick and make some power with other supporting mods.

Tripple 63's have made 900+ on some cr's

I dont really think im a fan of tripples. The route i was gonna go was silverbullet 62 with a s475 or something like that. I would first use the 62 as a single and then upgrade to twins. The part that im unfamilliar with is the larger s-framed turbos. Any help there?

If you wanna do twins 64/71 off the manifold is what I would start with, as for the primary the s478/92/1.1 a/r t6 gets my vote

Care to share your reasoning behind your choice?

the 64 has been the popular choice for singles on 12v's for a while, its just a good combo with that turbine wheel. as for the primary the 478's are more $$ than the 475's with a 96 turbine but they will spool faster and flow more air.

Just for the sake of arguement why not something like a 62 with a s480 ?

you could, but that 480 is very lazy on the bottom end. the 62 is a good charger but the 64 is better, spool up with either the 62 and the 64 is very close.
