thanks for any body that can adrees this or make it more clear

wouldnt make any difference to your hp but would make a difference to you hp per ton figure

Depends on how much bhp and weight you have in the first place!

Really think you will need to do the maths. If you had 100bhp and a 500kg car then you would need to lose about 2.5kg to have a power to weight ratio of 101bhp/tonne.

b****r I think I need to go on a diet  Must be down at least 8bhp/tonne

John,

As Nic says above, depends on what you have in the first place.

A 600 kg car losing 50 kg wouldn't get as much gain as a 500 kg car losing 50 kg so you will need to do the maths or play a little longer on my calculator

BTW: The calculation is - Power / Weight * 1000

thanks every one for the feedback

just used the 100kg for a round figure

my calcs were 2.5 kg to gain 1 hp per ton my mate said thinks its more like 5kg loss to get 1 hp per ton

will have to have a look later

In a normal tin top say average 150bhp in 1.5 Tonne 100bhp/Tonne

a 10kg saving is 0.67% f the cars weight so by loosing 10kg's your going to gain 0.67bhp/tonne i.e you'd now have 100.67bhp/tonne.

In a 200bhp 500kg car the bhp/tonne is 400!

a saving of 10kg's is 2% and 2% of 200 is 4 so you gain 4bhp/tonne. which is equivelant to 2.5kg to gain 1bhp!
