Message: [QUOTE="ja_cain, post: 1425243, member: 11928"] I think the exhaust side (with the larger turbine) of the sxe turbos are probably more efficient at scavenging energy from the 7.3's exhaust flow. I think this is probably even more apparent at the typical lower rpm towing speeds from 1800-2000 compared to the 38r. Couple that with a well designed compressor wheel and you have a winner. I think Ty, Jake or somebody mentioned this, but I think more work should be done to setup a/the wastegate so as to keep the turbo in the most efficient part of the map through most of the normal engine operating range. Companies like B&W and Garrett have some awesome cfd software available these days. I'm sure they are utilizing it come up with more efficient wheel designs on both the compressor and turbine sides. Everyone talks about turbine size and a/r, but shape/profile of the turbine could almost certainly be optimized just like is done with the compressor wheel. You can't throw a more aggressive compressor wheel on and expect the same turbine to drive it efficiently at lower exhaust velocity/energy. Hence the lower rpm issues with the billet wheels on the 38r. I'm rambling now and need to shut up.
