2010 Borg Warner Airwerks Turbo catalog

as for buzzwords? Im guessing that variable turbine geometry like on the BV50 or the soon-to-be-released S300V would be BW's buzzwords... as for the FP HTA compressor wheels, evodan's twinscroll hta is doing real well, and we have the twinscroll HTA turbos in stock.
My favorite BW turbo for the evo at the moment is their S300SX 88-75 with a 1.00 a/r turbine hsg and a std compressor housing (no 90 degree). That would be an awesome turbo to compare to the twinscroll HTA86 on dan's car and the 40Rs weve used on other builds
thanks guys!
shoot him an email, his gf got surgery today so he was out of the office but will be back tomorrow. Im curious to see what the K29 billet turbo does on an evo - it could be very interesting on a built motor with a twinscroll header...
agreed on all points, and from what ive learned you cant judge a book by its cover with the BW turbines, im excited to compare them to one another and the smaller garrett 30R stuff... weve got a lot to learn!

Hey geoff, how does the BW s300sx compare to the s366 ETT non XL turbo which is a 8" turbo. I have limited space under the nsx and I want something that will fit without modification to the frame. I am aiming for about 700whp.

Steve, in no way am I trying to start a dyno debate but I am curious what one? PM me the answer if you want to. I am curious since it was on a DSM if it was a Link car and if so what the estimate lbs/min was?
Thinking about a 366 on a M30 3.5L BMW project one of my friends and I are doing...looks like time for some math

If i were building a twin turbo NSX, i would use the twinscroll 88-75 1.00 a/r with one header having its own tial MVS wastegate and completely seperated going into the turbo. if you have questions lmk
hey mike -- i spoke with the borg warner engineers and they were really interested to hear about your problems and are happy to work with you to figure out why the turbos failed. if you woudl care to speak with them let me know!! they do have diesel applications that are running this boost level and greater

geoff I am just planning to run a single turbo. I want about 650-750 whp and I want to run a divided t4 turbo. Incase I decide to upgrade later. I might just go big with a sc6765 or something and get 750 and up the boost later if I want more.

Here are the 360 thrust bearings for the S200, 300 & 400 BEP turbos
Couple more pins or screws and those thrust bearings are ready for high performance use!

had one or two Rb series running them to 42psi never anything towards 50, never EVER had a turbo hit as hard as a BW, you do sacrifice a small amount of spool time but man any car feels like a jet trying to lift off the ground.
Hopefully pretty soon ill be getting a haltech from you and testing one of these K29 billet BW's, no doubt ill take that Piece to 50psi maybe 55
wassup Geoff

I made 479.5 whp and 443 ft/lbs on straight pump gas at 28psi with an S258 in the BEP T3 .70 hotside, which is a pretty big laggy housing for that size turbo. This was also on a DSM, bone stock 6 bolt (7.8:1 compression), stock head, mild FP2 cams on stock valvetrain, stock intake manifold (LOOONG runners).
