tyottsoarer Regular Location: Gold Coast Registered: June 2004	Power to wieght ratios , how relevant are they? Wed, 20 October 2004 10:47 Ok so when I was a younger car enthusiest I thought the maximum power a car could make was the absolute mark of how fast it would be on the road. Now I realise how stupid I was (this was only 3yrs ago). Wieght is abviously just as important to a cars performance as the power. I looked up specs on some of the most comman imports around and looked at there power and wieght and compared what i knew about each car in there relative performance. http://www.carizma.com.au/Print/Details/ that is where all the specs were gotten from here are the specs i got: Engine Car Power Weight Torque Weight/Power (Kw) (Kg) (Nm) (kg per Kw) CA18-DETSilvia 131 1090 225 8.32 1JZ-GTE Soarer 208 1623 362 7.80 RB25-DETR33 Skyline 187 1530 296 8.18 SR20-DETSilvia 153 1090 274 7.12 2JZ-GTE Supra 208 1590 427 7.64 * power to wieght was gotten by dividing the weight by its power so by these numbers an sr20 silvia should beat a supra, but that obviously isnt the case. How do these numbers apply to a cars performance in reality? I also realize factors such as transmission ratios, max torque and traction are major factors as well but how would these factor in?( I guess this would only be relevant in a straight line) Any help or discussions would be appreciated [Report message to a moderator]
