Cheers Rob, have you seen the youtube video of Kyle Dunkles 8000 lb Peterbuilt running a low 14 second quarter? Oh yes, he smoked a 240 BHP 2000lb Mustang at the time. Pete was giving 1000BHP but most important was the 3000+ ft/lbs of TORQUE! 8 wheels driving and he did mega burnouts, that's TORQUE for you!
When you tighten a whel nut up you do so to a given TORQUE figure, 100N/m for example. This equates to a FORCE of 100 Newtons being applied perpendicular to the radius from the centre of the turning circle at a distance of 1 metre from that centre. How much power is exerted?
Power is a measure of work done, or the ability to do work in a given time. BHP figures are a mathematical result of torque produced multiplied by engine speed and usually divided by a constant.
200ft/lbs of torque at 2K rpm will be more use in a road car than 1000BHP at 18K rpm and will accelerate that same car much quicker.
