100 pound loss = how much HP gain???

That's why I'm kind of done with this thread... LOL. Everyone is bent on ET slips, and the faster you go the harder it is and more hp it takes, and traction. I thought i made the point in my opening post that i was aware of the tenth per 100 lbs. That is why I made the question bigger lettering and underlined it. How much HP equivalency is a 100 lbs loss? LOL :D :D :D
What this tells me is nobody knows how much hp I have to add to make up for a 100 lbs added. That's fine.

Nobody can tell you until we know the weight of a vehicle@the line, a previous time slip for mph, then we know your hp, then it can be worked out reasonably close.

A 3000lb car that has 650fwhp can run 9.70@138, the same car on the same day with 100lbs taken out needs only 628fwhp to run the same ET/mph...22hp less.
A 3500lb car with 650fwhp can run 10.21@131, @3400lbs its 631hp....19hp less
A 3500lb car with 300hp can run 13.21@101, @3400lbs = 292hp, 8hp less.

Also 10hp is not necessarily 1/10th in ET. My old 340 Cuda ran 12.40@108 na with 368fwhp. It then ran 11.01@122+N20 which is 14/10ths faster (140hp)...but it made 157hp more on the track to run the no.
