This brings to mind a question I've always wondered about: how different are the lap times between cars and bikes on the same track? Clearly bikes have an advantage in power to weight ratio against all but the most exotic (eg: F1) cars, but does the car's differential in contact patch and downforce make up for it?

Say you took an R1 and a Porsche Turbo Carrera to Willow Springs, would the R1 leave it in the dust or would they be fairly even?

It depends.

There have been a number of comparos. It's usually a wash. Cars do a bit better on the long tracks. Bikes do better at acceleration. But like anything else it's the skill of the pilot that makes the difference. Cars are easier to drive fast because they don't lean and have different lateral force considerations. I've seen comparos of lateral G forces and motorcycles lose in comparison to cars. But the time a bike loses in the turn is made up on the straights.

True for bikes against street cars.

Race cars with fat slicks and wings beat bikes every time.
