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.
So according to you, i make 2460/240 = 10.25
2775/10.25 = 270.
I'm using crank hp.
Hmm.....
