BW Turbo Question...
I was wondering if anyone has been running the Borg Warner S372 or S374 with the T4. I see that everyone goes with the T6 and I would like to know if anyone has dyno numbers for the T4 frames? Thanks

I used to be under the same impression, but when I bought my turbo it was sold to me as a S475, with the race cover, 74.5mm compressor wheel and a devided T4 flange. I am thinking that maybe the first number has to do with the size of the turbine wheel and not the flange? I purchased it from a local shop here who is a dealer for borg warner (It did not come from bulleyes racing where I think they have their own nomenclature). Since then I have done some research on the interweb and have found many S475 turbos for sale with T4 flanges here is an example http://www.turbomustangs.com/smf/ind...?topic=76179.0 . So it would be nice to understand the nomenclature a little better. Anybody ???

I have changed up my motor and intake setup since, and figure its time to upgrade the Turbo, hence I'm looking for some numbers with the T4. Im not going T6 flanged as I have no desire to change out the entire manifold.....
Some dyno numbers from others would be great:-)

well if your looking at upgrading the turbo, ie making more power then i would go for a s475 if you not gonna go with a t6 version, choose a t4 version with a 1.25 rear end to help it flow the best it can at the top end, will help over come the smaller t4 a bit
