...any kind of (gasoline at least) engine powering any kind of chassis, etc. can run in NASA ST or SU.
But, SU is not on the list for ITE.
Period.Super Unlimited (SU) is an unrestricted class for any closed wheel/fendered vehicle that complies with the safety requirements in the NASA CCR.
Correct you are.Thanks Gregg, I think the rules could be a bit more clear then. But, as far as the philosophy is concerned, I'm not sure why you would want to restrict ITE unless you are intending that the tubeframe cars & non-DOT tires would fit in SPO, which would seem to make sense...
