TT + 390ci..........which turbos....Modular Turbo CBR F2.... So, I've decided to go Modular Turbo TT kit.....after talking to Robert last night. So......which turbos would be good to go with to make 1,000 RWHP or more (1100-1200 would be nice too)........full time E85 and the Modular turbo A2W intercooler they use and through my 4L80E. Mini-tub and any suspension mods it needs to help it hook. Full weight, full interior.
OR......which mismatched turbos, two different sizes to go with.......
STREET CAR ONLY......STREET CAR ONLY.......roll races ONLY. 40-170mph.
5-6 months is when they can take the car.....I'll be driving it N/A till then with the 390ci........

A twin T76 will be nice. Kinda against the grain and bigger than what most people do. I'm doing a twin T76 build. With a 408, it should be absolutely perfect. Ive done a lot of research on this turbo with compressor maps, engine specs, RPM ranges. It should be a great combo. Very little to 0 lag, 7600 RPM shift redline, turbo is on the verge of surging right after my shiftpoint. Very efficient. Should come alive at around 2200 RPM. Good luck with your build

6266's would easily reach your goal and spool very quickly. As for twin 76's, I wouldn't personally use them unless you are aiming for something near 2000hp.

I would go with twin 76s. I know on a standard deck LSX with twin Precision 76mm turbos make around 1500-1600 at the flywheel. My builder just dynoed a single cab silverado with the setup just mentioned with a billet Wilson intake manifold and the truck pushed 1467RWHP in a Dyno Jet on race gas (which I dont remember). Build still has couple of work to be done to it to be fully complete

6266's aren't going to spool at 1000rpm. Even if they did, a boost controller would easily take care of any traction issues and on a build of this level, it's pretty much a necessity. 76's with a proper sized turbine to actually use the compressors, not p or q trims, will take a LONG time to spool on a street 390. They're completely unnecessary for less than 1600 rear wheel.
