Hey guys!

I was wondering what the mechanical differences are between the S50 and the S52. I know the S50 has a higher redline (7400 rpm vs 6500 rpm), but that can't be the only reason the S50 is much more powerful. I also know that the S50 has individual throttle bodies, and the S52 has a more standard intake manifold, but are there any other mechanical reasons for the S52's lower hp rating, or is it just the way the ECU is mapped?
