Default Is there some way to find out...

Hi guys, i've been wondering is there some way to find out how much faster a car would go for every pound taken off. I mean that even if you drive a opel corsa 1.7tdi that does 60 in 15 secs. (or more i don't know) it would be faster if you take off ..let's say 220 lbs.

What do you say?

This joke is creating mayhem
BTW, this is probably something for the Car chat or mods section

Funny this topic comes up. My bike weighs 325lb and has 43hp

I weigh 205lb (fat bastard)

So power to weight is 530lb/43hp

Now if I lost 30 or 40lb how much quicker as a percentage should/would my bike be, in theory?

This has been going round in my head for a couple weeks now!!!

I'm just about to go to bed now but if anyone is that bored and wants to work it for me, then that'd be cool!

Let z represent the change in acceleration.

orig. acc. = force / 530

new acc. = (z) (orig. acc) = force / 490

(z) (force / 530) = force / 490 [substitution]

z = 530/490
= 1.08

This means an 8% improvement in acceleration with a loss of 40lbs.

Thank you jasc!

For the record the bike should do 0-60 in about 6 sec so just under 5/10sec improvement!

8)
