Power to Weight Ratio

[stiffler69]

Just wondered if someone can do a power to weight ratio on these two cars

first been a 206 gti 137bhp not sure i think the weight is 1050kg

And now a 206 xsi 1.6 16v 110bhp around 1030kg's in weight

Now these are the standard fiquires, so what i would like for someone to do is work out how fast and how many ponies he would need to gain to make his car get close to a gti

The reason for this is there is a member on the 206 forum beleives his xsi will stay with the gti to 60mph and the gti will only pull away after 90mph, now his car has a sports cat, exhaust, induction kit and he has had a remap so it may have around 120bhp if im been generous.

Anyone who is good at these conversion please help as i dont know how to do them or how where to start

thanks rep will be left :y:

brilliant we converter

Thats the site i used :y:

[saxostuart]

Thats the xsi with 120 bhp

Power at Flywheel (BHP) : 120
Weight without Driver (KG) : 1030
Power to Weight Ratio (BHP Per Ton) : 118.38
0 - 60 (Secs) : 8.86
0 - 100 (Secs) : 26.86
60 - 100 (Secs) : 18.00
Quarter Mile (Secs) : 17.34
Terminal Speed (MPH) : 80.34
Drag Strip Quarter Mile (Secs) : 17.14
Drag Strip Terminal Speed (MPH) : 81.69

just a second off the gti on the 0 to 60

[Jackman]

Still quite a large difference int he BHP per Ton tho.

[dannygti]

until i found that site i used this method to find out bhp/ton

1000 divided by weight multiplied by power.
my bhp per tonne is 164bhp/ton

could be a good thread starting here.

[stiffler69]

did they do a xsi with 120bhp i couldnt dig any info up on a 120 version just 110bhp version

[Wayne]

no they didn't mate just the 110bhp model.

[TypeRhys]

your all forgetting the Torque ! ! ! !

[stiffler69]

Yeah and the gti has 142lb ft torque

[shahvts]

look mate it simple if u divide cars weight by power u will get to o to 60 for example 1030/110 = 9.36 to make it more accurate add your weight in because 1030 kg is the cars weight not including u. it not entirely accurate give or take. from my calculation you will need about 130 bhp i ll show u
1030/130=7.92

[Toad]

Even with BHP and torque, it's still all guess work. Calculating the power to weight ratio is fine, but it's pointless when trying to estimate acelleration, as there are far too many other factors involved.

[Richard07]

is the vts's gross weight the same as a gti if not what is the weight?

[Toad]

They're refering to a 206 gti...

106 GTIs and VTS's kerb weights are both 935kg.
