Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
yeh but like how do they " tune " it?? wat do they axully do 2 make u get more kw? thats wat i dont understand.:bang:
dynos dont measure rwhp/rwkw
they measure torque and calculate the hp/kw from that
Dynamometer - Wikipedia, the free encyclopedia
Beat me to it.
Power is just a calculation. It doesn't really exist. James Watt thought it up when wanting to talk about the effort required from a pony to move coal in a coal mine. At best it was an estimation because horse couldn't sustain the effort over a period of time at the figure that Watt came up with.
It has been passed on through the years as a figure that people use to rate the available power of a machine. An engine doesn't produce power at all, it produces torque (twisting effort), this is measured and converted to hp or kW.
To answer the OP's question a bit more, a dyno loads up the engine by providing resistance to the rollers and measures peak torque. This is when the engine loses it's ability to spin the rollers at certain revs.
