I'm going through the process of selecting a turbo, I've definitely decided on the gt28 series but don't know exactly which one to run. Doing some rough estimates at 6k assuming 90% VE and a PR of 2.3 (~20psi) a 4g would flow 439 cfm or 30.7 lb/min. (2.0l*6000rpm*90VE*2.3PR/5660). At 1/2 flow = 15.35, and 1/5th flow (at PR of 1) = 13.35 lb/min
I mapped it out on a gt2860rs map and it looks to small (excuse the crude paint rendition) , did I make a mistake somewhere? And who's running this turbo currently and can give me some feedback on its performance? Doesn't really fall into the middle island all to well.
