Power to weight ratio of your car?

Django x2 · 5 Jul 2011 at 14:19

PMKeates, what have you done to wind it up to 350hp. I don't know of any companies offering guarantees of that sort of power. Have you had it dyno'd?

Oh and Skeeter re the Clio, if you think 172 / 182 denotes just a number, the serious internet LOLZ to you. It doesn't. It's the PS/DIN output of the engine, as PMK has described. "Just a number". LOL

294bhp /tonne at the moment.

When the new engine is in 444-500bhp/tonne

Princey · 5 Jul 2011 at 14:29

Hopefully it should be 304.21bhp/ton later this year.

ZS TD: 155bhp / 1.25 tonnes = 124bhp/tonne

ZT190: 187bhp / 1.4 tonnes = 133bhp/tonne

I went with Evolve. They quote for their maps:

BMW E60 535d 286 bhp / 580Nm > 350 bhp / 700Nm
BMW E60 535d 272 bhp / 560Nm > 340 bhp / 680Nm

When there they offered 380!

DM · 5 Jul 2011 at 14:38

should have gone for the full on beefy 380 jobber

PMKeates · 5 Jul 2011 at 14:39

Unfortunately the 380 takes the transmission above its rated torque output

mattyprice4004 · 5 Jul 2011 at 14:41

PMKeates, what do you do for a living? I'm genuinely interested.

BMW 330ci 154hp per ton, (231/1.5)
Mini Cooper, 183hp per ton, (110/0.6)
Vaux Astra 2L Diesel, 70hp per ton (98/1.4)

That must be a really lively Mini Cooper!! Can we get more information? That is a lot more power over stock.

I can have mine mapped to 682bhp they say, thats very tempting

snowdog · 5 Jul 2011 at 14:44

129 bhp/ton.

163/1.26

CaptainFail! · 5 Jul 2011 at 14:51

Renaultsport Clio 172

165bhp-ish/1.1 (estimated bhp figure by the way!)

150 bhp/tonne

Gamefreak501 · 5 Jul 2011 at 15:02

Hmm

My Spitfire is meant to have around 68-71 horsepower and weighs 814kg.

A quick calculation, on the bottom end of the bhp spectrum (not taking into account horsepower loss over time) is as follows:

68/814 x 1000 = 83.5bhp/tonne

Indicating I have 83.5bhp for every 1000kg.

Kind regards

Old car = X-type 2.5 V6 Sport

194 bhp
1555 kg

124 bhp/tonne

New car = SLK 200 Kompressor

184 bhp
1415 kg
130 bhp/tonne

PiKe · 5 Jul 2011 at 15:11

188bhp/tonne

Standard S2000.

scoobyrichuk · 5 Jul 2011 at 15:30

Impreza Turbo 2000

(1000/1235) * 237 = 191.9 bhp/tonne

When remapped it should be 243 - 267 bhp/tonne :cool:

The official PS figure for the 172 is 169PS, or 167bhp. Wherever this number comes from (according to PMKeates, another, higher, measure) it is not PS or BHP. Its unsurprising that Renault chose to use the highest measure they could, but the 172/182 is not a bhp figure, which is all I was trying to say oh so many pages ago.
