I don't know if anybody mentioned it (I didn't completely read all these posts), but I think there are big differences, with the way a manual trans, and a NON lock-up automatic trans put power to the rollers. Given the same engine, the manual will put down bigger numbers, I think.
- I figure the manual, obviously, won't have the slip of the NON lock-up converter, and as a result, a better load is put on the engine, getting the turbo(s) to spool a little earlier/easier.
. . . if that makes sense.
One thing I have learned is that my money is better spent using a dyno as a tuning tool (the last two or three times I've been on a dyno, and tuning between runs, I left with at least 50 more peak horse power).
The track shows what it can really do.
If you go by CompD's HP calculator . . .
The 6400lb cinder-block going through the traps at 103.35mph gives us: 479hp at the rear-wheels, or 520hp at the flywheel.
or . .
The 6400lb cinder-block making the pass in 12.67 seconds gives us: 516hp at the rear-wheels, or 560hp at the flywheel.
Who cares, it's fun as crap!
