MING Posted May 7, 2005 Share Posted May 7, 2005 hi all can any one tell me how to work out power 2 weight ratio ming 😬  so many supercars so little time!!!!!! Link to comment Share on other sites More sharing options...
Beelzebub Posted May 7, 2005 Share Posted May 7, 2005 Right, I'm no mathematician but try this. 1000 divided by vehicle weight in KG's multiplied by your "at the wheels BHP figure.  Example 1000 divided by 560 KG's =1.785. Multiply this by your power output 200ish = 357.1 Errr BHP per tonne. Howzat 😬  Edited by - Davesport on 7 May 2005 17:19:02 Link to comment Share on other sites More sharing options...
MING Posted May 7, 2005 Author Share Posted May 7, 2005 cheers dave busily removing shoes and socks now in order to try and work it out ming 😬 so many supercars so little time!!!!!! Link to comment Share on other sites More sharing options...
MING Posted May 7, 2005 Author Share Posted May 7, 2005 are you sure it the "at the wheels" figure? if so my blackbird only has a p/w ratio of 288bhp per tonne  so many supercars so little time!!!!!! Link to comment Share on other sites More sharing options...
rgrigsby Posted May 7, 2005 Share Posted May 7, 2005 Normally it's worked out using the at the flywheel figure, ie the R500 would be 230bhp where as it's at the wheels figure was considerably less.   Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Beelzebub Posted May 7, 2005 Share Posted May 7, 2005 Power output after losses would IMO be the figure to use. IE what's seen on the rollers 😬 Link to comment Share on other sites More sharing options...
Beelzebub Posted May 7, 2005 Share Posted May 7, 2005 Top Tip. Take some Andrews liver salts Every little helps y'know 😬 Link to comment Share on other sites More sharing options...
Ferrino Posted May 7, 2005 Share Posted May 7, 2005 I imagine most PTW ratios are quoted with flywheel BHP, so that would prolly be best for comparison. Bite me 😬 Link to comment Share on other sites More sharing options...
