I'm just wondering if there is an equation, by which you can use to say "hey, I reduced my FRS weight by 100 lbs , so that's like me adding say 10 more HP to the car" ?

This is the simplest one I've come across. It should be fairly accurate. Feel free to correct.
Original weight divided by HP = 2750/200 = 13.75
Remove 200 lbs 2550/200 = 12.75
Then you divide the original weight by the new Power to Weight Ratio 2800/12.75 = 219.60
It gets interesting if you add a header/tune and bump the HP up to 230 crank.
2550/230 = 11.08
2800/11.08 = 252.70
BTW I have removed 220lbs from my car and it makes a noticeable difference. I'm working on removing another 100 this winter.
