Goat Boy, I did this calculation on here a page or so back whilst trying to be a smarty pants,
[QUOTE=MarioNZ]
Just cos I like getting my calculator out:
V8 Supertourer site quotes HP @ 'around' 575 and weight as 'less than' 1300kg incl driver = 442 hp/ton
V8 Supercar, lets say a generally accepted 640hp and class weight limit of 1445kg incl driver = ...........wait for it........ 442hp/ton!!....well, actually to be honest I wasn't expecting that result

Supertourers quote 507lb-ft for torque but I have no idea what a V8 Supercar produces so maybe someone who does know can do that maths
