Having thought about it a bit more the tyres on a EuroBoss are designed to do shorter distances than the CART, so should give more grip. I also forgot that CART cars are heavier than F1, and that one CART car raced in BOSS last year,
So now I say that the lap time would be about the same if not the CART being slower. That is until the CART rule makers give out the pop off valves for the turbo's
