Tue, 29 July 2003 23:25 Wastegate is pretty much on the money there except : Power is a product of revs and torque, not a derivative (sorry to nitpick) and most 1.6's have more like 145-155 Nm of torque and variable cam engines tend to have slightly more. The factory figure is something like 160Nm (this is probably a little optimistic). If we use a torque of 155Nm we get 9672.5 rpm to get 157Kw, a little more believable but still very high. Also, it is very hard to dramatically increase the torque of an engine. Basically to get more power you just move the torque band to a higher rev range (I'm ignoring turbos, capacity increases etc.). The thing to remember is that petrol only puts out a certain amount of energy (about 45 Megajoules/kg), and since power = energy/time and we can't control time we just have to burn more petrol and release more energy. How do we burn more petrol in the same amount of time? Rev harder, or force it in with a turbo, or make the cylinders bigger. Also remember that there is a theoretical maximum efficiency of an I.C. engine called the Carnot Efficiency, and it is impossible to exceed this. So hands up who wants to do the sums on this 120Kw @ the wheels 20V, and see what its efficiency is? [Updated on: Tue, 29 July 2003 23:28] [Report message to a moderator]
