this may have been discussed before, but i got into this conversation a couple days ago with some big car guys, so i thought it might be a good topic here. my own view is that at a certain point, you can no longer put the power to the road. and at a further point, you cannot operate the without computerization. and in an attempt to set some ground rules, i suggested that the discussion only made sense if you were talking about power to weight ratios. so for example, my own f40 has somewhere between 550-600 bhp (bigger turbos), and weighs about 2900 pounds with all the fluids topped up. so the power to weight is approximately 1:5 it has no driver aids. poodling around it is easy to drive. driving it aggressively requires a bit more attention since the torque and bhp comes on rather quickly when boost builds up. i think it has enough power, but i realize this is a subjective opinion. some might rather have LM versions with higher bhp, and lower weight, maybe 750bhp and 2500 pounds for a ratio closer to 1:3 which is probably more than enough for all but the very experienced or professional drivers. which leads us to more modern cars where we have a horsepower war going on. i would posit that none of them can really function with a ratio lower than 1:5 without computers, and that even with computers, none of them even really need to be less than 1:4. all this is subjective, and i dont have the same opinions as others. thoughts?
