Absolute Max effort twin S366's on 400"??? So how quick/how much power can a pair of a out of the box S366's run/make? how about a custom pair? 400"ish engine size, max effort conventional heads (LS3/LS7 ports) wet block, still streetable. Say 650hp N/A engine that can handle all the air the compressors can push and the turbines will flow without building stupid high back pressure.

These turbos just interest me for a few reasons. I feel that they are capable of more power than most people think, without sacrificing reliability. Borg Warner is stepping up it's performance offerings with some optional parts that fit these John Deer diesel spec turbos, as is the aftermarket. Tial is offering ss v-band exhaust housings for the 68mm ex wheel (which is 2mm larger both exducer and inducer dia than Precision's 6766), they will be offering a housing for the 73x80 wheel late this year. Midwest, Forced Inductions and other custom shops offer compressor wheels up to 74mm with sleeved/custom compressor housings. Bullseye offers custom exhaust and compressor housings and I hear Borg warner themselves will have a slightly larger compressor wheel and housing offering soon. They are slightly smaller in std T4 flange than a GT42 chassis offering by Precision, Comp, Turbonetics, etc.. and with the V-band housings are much more compact.
It just seems to me that these will be the next platform to take off. I really feel like in competent hands a custom builder could build a pair that would reliably produce 2000hp and not break shafts, kill thrust bearings and still be quick spooling.

Slightly, I just like to explore options that aren't popular. This seems like the best option available today for what I want to accomplish today for the dollars spent. I talked to Bill Devine at Bullseye 6 months ago and I like the packaging of his turbos, but I'm not sold on the Batmowheel compressors, especially not at around $1900 per turbo.

Its just not enough compressor. Even the HIGH END Hondas which really are much more efficient air movers than LS (per cube) make around 1000 FWHP on cheater 67's with the largest compressor cover and turbine wheel you could run on a 4 banger.
But, the Tail housings will be huge for the BW crowd. IMO the size and weight of the BW turbine is the biggest turn off when comparing to its competitors. Stinks how expensive the tial housings are.

I'm thinking I'll get closer to that 900-1000 hp per turbo mark that the imports are getting to with singles. This is just a mock up, Greg from Tial is assembling the turbos for my car with billet 67mm compressor wheels. stay tuned in for results.....
it may be 2mm bigger that the 6766 exhaust wheel, but the technology and flow of the precision better. The S366 is a brute solid unit though. look at the blade area though. 66vs67 doesnt seem like much, but look at the size of the shaft/nut. the precisions are much smaller, and the blades are machined much further down. the 1mm larger compressor wheel, flows damn near what a 72mm BW cast wheel does due to the area the shaft takes up as well as blade design
s366s with cast wheels flow about 80 lbs/min. billet wheels a little more. i would get the t4 .90 exh housings with the clipped 73 or 74mm exhaust wheels. should spool good and still flow great with the big exh wheel.
