What MOD next? TT or SC?

You are correct that drivetrain loss is somewhere between 15% - 17% on a manual transmission Z. The big part you are missing is the torque difference between a tt and sc Z. The hp numbers are similar but the sc makes power higher up in the rev range. TT makes power in the middle of the power band and makes more torque.

HP = (Torque x RPM) / 5252

In general torque is king in a drag race. HP comes in to play at top speeds. In short if both a tt Z and a sc Z have 550hp, the tt Z will have more torque and be faster in a straight line. The benefit to me of the sc is that the power curve resembles that of a stock Z and retains driveablity on a road coarse.
