The big question is what was the original weight. I have seen everything from 3,010 to 3,300 lbs. in the searches I've done. All I know is that when I got the car classified through the SCCA and had DC deliver the manufacturer specs. the dry curb weight was listed by the manufacturer as 3180 lbs.

Now bare in mind I had exactly 3/8 of a tank of gas in the car when I weighed it today, which would be about 36 lbs of gasoline.

So since I'm going with the SCCA specs. of 3180 lbs, I have removed appx. 440 lbs from the car. Now does anyone have the equation that relates hp to weight ? In other words, if I have a 215 hp car that weighs 3,180 lbs and I have a X hp car that weighs 2,740 lbs. what is the equivalent hp of car X ?

I always sucked at algebra... But I get an equivalent HP of 249.5 Can someone check me on this ?

Granted I removed a lot of stuff, but 440 lbs ? And I still haven't gotten the AC unit out yet...
