100 pound loss = how much HP gain???

Big part of matching the 1320/mph=et formula is clutch/converter/gearing that allows the engine to operate between it's torque peak and it's horsepower peak. When you have that, it's usually pretty easy to come within a few tenths of the formula. It's those last couple of tenths that require quite a bit more effort.

The formula is a general yardstick for comparing efficiency, it doesn't care much about power/weight ratio or how expensive your engine is.

I believe a lot of the discussion here is a difference between a low-powered high gear automatic mid 13 car getting traction as opposed to a high geared clutch car mid 11 mid 12 or worse yet 10.99 or lower getting efficient and traction??
Do you believe this fine line gets even finer?... As in shedding 100 lb getting you that extra 10th at certain levels..
 
If traction is an issue it depends on where the 100lbs comes from. If it's from up front and the car is rwd, removing 100lbs will probably help traction and give you more bang for the 100lb reduction. Just the opposite if the weight removed was inside the back bumper.

I think the Op was looking for a direct answer of how much horsepower you would gain for LOL for a hundred pounds of weight loss...
And this is almost in my opinion a trick question..
The obvious thing people are going to want to know is the current ET..
It's my strong opinion that once the ETA gets down to a certain level these hundred pound are affected at different levels and as you are pointing out in different places in the car as well...
