Is there some way to find out...

[thepest]

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?

well the lighter the penis the faster you can thrust I suppose :wink:
This joke is creating mayhem :P
BTW, this is probably something for the Car chat or mods section :wink:

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.

Damn guys thanks a lot it! That really is helpful.

Thank you jasc!

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