Yup. Borg Warner S366 for me this year hahaha.

yeah the new naming system is gay. one thing people forget is that you make as much of your power on the exhaust side as the compressor. case in point, a gt35 may be rated for 750hp, but it has such a high pressure turbine, most people never see it. step up to a gt42 with the same compressor, and the 750hp becomes attainable fairly easily. now as far as big turbos go, these new designs flow so much better than the older bigger ones. specifically this 75 mm is the repacement for the TV8101/8102. the 8101 was an 85mm compressor, and a bigger, heavier turbine. this new 75mm will keep within 10lbs/min of that old one, and spool is around 800rpm sooner, with a broader efficiency range. also the 80mm upgrade is $240, and then it actually exceeds the old 85mm a hair. This s400 is the same turbo that Innovative uses for its $2000 dollar GTB 88. and i can have the same thing for a little under $1200. Turbo companies are ridiculous in their markups. Heres the map for the 75mm compressor. Ive never seen a map that wide and flat before. Man you can beat the pricing on these Borg Warner turbos, its really making it easier for alot of these guys to build bitchin setups on a budget. Also i was looking at a gt42/47 based turbo, but it uses a high pressure turbine, more suited to high rpm, small displacement engines, and is a real choke point on these bigger v8's. the big turbine is also very kind to the tires as boost is very controlable with the throttle.
That s366 should be a nice addition to your ride, now if it was right wheel drive you might be able to do something with all that power! Hope your driveline holds up for awhile this year.
The rest of my fuel system stuff came today, aeromotive filter, -8 and -6 fittings and braided hose. can plumb this thing in now and see if my wiring works, hopefully be able to turn it before christmas and see how much shit i f-ed up on this wiring.

BW does some interesting stuff. In garrett terms, your turbo is basically a GT4276 on the compressor side, and a GT47 on the turbine side. Should work ok with your big cube motor, I'm looking forward to seeing a dyno to see how it spools for you, etc. What a/r are the housings?

its a 1.32 divided t6, that thing is heavy as hell, i need to figure out how im going to mount the damn thing. I am a member of turbomustangs.com, and those guys know their shit about turbo'ing V8's. anyway most of the guys with 350s spool it around 3500, and an ls1 around 3200. with the 6.0 it may spool by 2800, but im expecting around 3200 since i have so much volume to fill. at any rate, the motor makes around 420hp N/A, and as much torque. i know keeping the tires planted with my GTO was a chore, and this should be about 15hp more than that, which was around 410hp.
