Noz Posted October 25, 2011 Share Posted October 25, 2011 Guys, I've seen a ratio spreadsheet a few times on here that gives estimated speed, RPM and gear ratio depending on gearbox, final drive and diff but I can't seem to find it. I'm doing dynamic simulation for the NA 5speed and using differentiation and intergration calculations to work out acceleration and velocity when taking into considering air density, frontal area, co-efficient and car / wheel mass... ...so having this would be awesome as calulation speed using the torque in various drives would help me if I could see if my values are correct. Thanks!! Link to comment Share on other sites More sharing options...

merckx Posted October 25, 2011 Share Posted October 25, 2011 Gear ratio's 3/4 down the page and other technical info. http://mkiv.supras.org.nz/specs.htm Link to comment Share on other sites More sharing options...
Noz Posted October 25, 2011 Author Share Posted October 25, 2011 got the gear ratio mate was after the calculation sheet with various speeds and stuff, thanks josh thats the top gear spec, that will definitely help Link to comment Share on other sites More sharing options...

Noz Posted October 25, 2011 Author Share Posted October 25, 2011 lol i need it for my uni assignment. we use calculations as a flow diagram and change variables to gives acceleration and velocity outputs depends on air resistance, gear ratio and torque inputs. its basically using real life examples to calculate equations. it forfills my subject assignment. this is uni related mate not to fill my time as im bored. i make another headlight where everyone tells me my hole isnt big enough Link to comment Share on other sites More sharing options...
