how do you work out bhp/tonne?
coz i did 170 / 0.9 = 188.8
288 / 1.265 = 227

185 actually and using 230bhp and 1265kgs
and i had it weighed with the spare wheel and jack etc which weighs about 30kgs so i deducted that as that is now out the car.

power to weigh is calculated by this equation -
Power / weight x 1000 (metric ton)
228 / 1265 x 1000 = 180.2371541501967284584980237512bhp
seems closer to 180 than 190 to me...

that calculations not quite right robin, this os the correct calc for bhp/ton
(power/(weight*0.0009842)*100)/100

no, a metric ton is 1000kg.
thus making my calculation correct.

Correct Steve, neither are technically incorrect, but it is widely accepted that bhp/ton is measured metrically unless you are American.

But it doesn't matter if its metric or imperial, Chris has slightly more bhp/tonne (or ton, if were talking about imperial).

yes, but if they're both done using metric measurements, chris's GT has 0.7bhp per tonne more. which is neither here nor there.
