Numbers/rlosses may be dependent on dyno's used, so it may be hard to compare different cars tested on different dyno's.

An IRS will use more HP than a solid rear axle.

You usually chassis dyno a car in a 1:1 gear, the gear to have the least hp loss, so that would be 4th gear on a toploader, and 4th gear in a tremec. Loss, I guess, would be about the same, maybe giving the advantage to the tremec since it runs a thinner tranny fluid.
