F1 cars, even with the skinniest wings the rules allow, generate a huge amount of downforce. This allows you to pull over 5G (briefly and laterally) in some existing (not banked) fast corners.
A car with no downforce will see similar G forces (for longer and vertically) on a banked corner because the centripetal force from the banking is replacing the absent downforce.
The reason F1 cars can't race on an oval is that these forces are to some extent additive; an F1 car's driver would probably experience 8G on a banked turn that's giving a NASCAR driver a 3G turn. This increase in G-force combined with the increased duration it's experienced for and the fact that the majority of it is now vertical G-force would lead to drivers blacking-out in the turns. Then they crash, and someone probably dies.
Happily CART made this mistake in 2001 so F1 doesn't need to repeat it. See

I never thought of the vertical G loads on a banked circuit...Very nice post WillerZ thanks =D>
vertical g-force will be a function of speed, since an f1 car and nascar car in not going into the banked corner any faster the g-force will be same.
F1 car with wings flattened will produce less downforce than an cart car and have much more drag so let us not flatter ourselves here
banking at TMS is 24 deg, indy has a 9 deg banking speed carried through the corner is vastly different
the length and radius of corner at tms was unsitable to cart just as las vagas was unsuitable for irl last year
f1 at indy will be no different for to the current indy 500 with the exception of seeing 11 different chaises on track with a much more irritating engine noise that the crowd will leave
for car safety, the side pod will have to be extended closer to the front wheel axis to avoid a senna like wheel rebound (as it is exactly the way cars will end up on the wall), gear box crash structure will need to be lot stronger (to prevent a broken back like ralf`s)
