Not using the NHRA rulebook, we have our own. There are things IHRA is more flexible on, which inherently makes it cheaper. The problem is, in order for teams to be able to run both series, it’s really hard to have a ruleset that is much different. The sport as a whole needs that.
The whole race model that IHRA has a bigger effect. 10-race schedule. Teams don’t have to show up until Thursday for a Friday-Saturday race… much less expense on hotel and food. Only 2 qualifiers. Max of 3 elimination rounds. And finally, 1/8th mile. All of these things have a drastic effect on the budget needed to run at IHRA events.
