torn on turbo selection for my 408 build starting to track down parts for a new build and im torn on turbo selection. Gunna be a 6.0l iron block, stroked to 408, all forged internals, dished pistons to give me around 9:0 compression. 317 heads, 100lb injectors, hi ram intake etc etc etc. I want to make around 800-900rwhp on pump gas. I do not go to the track often but id like to be running in the low 10's high 9's when I do. Now I am torn between using TWIN master power p trim 70's with an .81 A/R, or running a larger single, thinking a s488 with a 1.10 A/R or possibly a turbonetic t88. Whats all yalls thoughts on those choices?

well now after a bit more research im thinking of going with the budget garrett gt88 1.23 AR, T6. Its good to 1400hp and should easily cover the 850+ rwhp I want with alot of room to grow. Any thoughts on this turbo or anyone personally use it? I hear its alot smaller (in physical size) than the s488 too which is always good.

thanks for the words of wisdom doc, I know you know your ish so the gt-91 it is. I only want 850rwhp or so for my street driving which will be 99% of what I do, but that one or two times a year I hit the track I want to be able to turn up the boost and make 1000+ rwhp. Im building the motor way overkill with all callies internals to easily handle 1500hp so it shouldnt be a problem. Ill be calling you guys and ordering the 91 when the time comes, hopefully in just a few weeks.
