Borg Warner 257
OK guys as some of you know this week I am tuning a 257 .63ar on 100% stock engine running E47. I'm expecting the stock fuel system to be able to keep up on spool but not topend on high boost but we'll see what I can get from it.
So if you haven't heard anything about the 257 here's some info
Compressor Specifications
◾Compressor Type: Forged-Milled Wheel (FMW) Extended Tip
◾Compressor Wheel OD (exducer): 76mm
◾Compressor Wheel Inducer: 57.2mm
◾Max Flow Rate: 64 lb/min
◾Compressor Housing Connections:
◾Inlet: 4.0" Hose Coupler
◾Outlet: 2.0" Hose Coupler
Turbine Specifications
◾Turbine Type: High Efficiency S200SX Inconel Turbine Wheel
◾Turbine Wheel OD: 70mm
Lots more to come after I get the trims dialed in I will post my first impressions but get ready for lot of info and updates as we get the tuning done

Oh shoot I forgot to close that thread sorry man. Yeah I got it figured out it was the two wires heading to the fuse box in the engine I got one on but not the other.
And thanks for the gl km0 and I keep talking back and forth of what we are going to do to this car. And I think the official conclusion is after this is all tuned out I'll do a full engine build (block,4340 rods, wiseco pistons, ported heads, stage 2 cams,and 82# springs.) Then I'll be satisfied haha.
