why not the LS2LS7? @ Jan 10th 2008 11:49AM
They can tune it all they want. With all the stuff required in there (myriad radiators, etc.) needed to house that engine, it'll never be a real track car, because it'll always be rather heavy.
I'm sure with enough effore they can reach their goal on the N-ring, since the N-ring is a power track and they're bringing a lot of power to the table.

It seems to me that a heavier car, with proportionate power, would outperform a lighter car (since wind-resistance would shrink, relative to power). Why would you think that the opposite would be true?

It comes down to ability to go around a corner. A heavier car has more momentum that needs to be changed to permit the change in direction. Adding power does nothing to overcome the increase in grip necessary to handle the additional weight through a corner.

If you want top speed, power is critical. And top speed matters a lot on the N-ring, so this car will be well suited.
But on the track, handling matters a lot. And I don't mean just skid-pad handling, but real changing direction rapidly handling. This car, as good as it is, isn't the kind of car that is good at that, because of the weight.

@both of you two guys,
The extra weight does indeed increase the momentum. However, it also increases the grip. In fact, it is axiomatic that the grip-increase has to be exactly proportionate to the momentum-increase. Are you claiming that, when a given vehicle is made heavier, grip does *not* increase exactly in proportion to momentum? if you are, I believe that you are essentially claiming that magic exists, and that the laws of physics do not apply to cars.
Gordon Murray has in fact made this very claim regarding the existence of magic:
