Less weight? how does it make you faster.
I am in the process of taking another 200-250lbs out of my EG hatch, it already has a track weight of 1980lbs including me. I was curious if taking the weight out is just gonna make it faster off the line, hence lower 60ft's faster at the other end or will it make more of a difference.
I already run low 1.8 60ft's.. but hoping to get it down to 1.5-1.6's which is about 0.4-0.6seconds. but will the less weight make it closer to 1 second???

You have a horsepower to weight ratio. You can increase it by adding hp or dropping weight. Easier to lift/accelerate 10 lbs than 100 lbs
Real world HP / Weight Ratio is dynamic. This is mainly because of rolling and air resistance. The faster you go, the less HP you have to push the car forward; this is mainly because of the increased air resistance. Because of this, lightening your car will make more of a difference at lower speeds than higher.
Lets take a 2000lb car that has 200WHP and assume that at 100mph it requires 100WHP to maintain that speed (no increase or decrease in speed)
At 0mph the HP/W ratio is: 10:1
At 100mph the HP/W ratio is: 20:1
Now lets drop 500lbs off the car, and take away 50WHP.
At 0mph the HP/W ratio is: 10:1 (same as above)
At 100mph the HP/W ratio is: 30:1 (more than above)
The point here is that while a 1000lb car with 100WHP will have the same "static" HP/W ratio as a 5000lb car with 500WHP, the 500lb car will walk away from the 1000lb car at higher speeds. Thats why dropping weight is going to make such a difference in your 60 foot times (assuming traction doesn't become an issue).
