Preliminary NMCA Stock/Super Stock (S3)Compo Rules 2017

[SS3718]

I reviewed quickly and one thing that jumped out is the NHRA vs. IHRA index. I'll use GT/FA as an example. In NHRA the index is 10.80. In IHRA, I believe it is 11.10. (Somebody correct me if I'm wrong)

Probably need to use IHRA indexes for all or have wording that says NHRA index trumps IHRA index when both organizations have the same class. That would leave the IHRA index in use for classes that are not offered in NHRA. Hope that makes sense!

The rules mention that weight is not a technical requirement, but there are pseudo-heads up runs with the dial in being .1 quicker than the faster qualified car. Will these runs, at least, be weighed?

Good point.
I doubt it would ever affect me if I ran their events, but racers in the heavily populated upper letter classes might be concerned.
They have scales at all of their events anyways, so they would just need an official there at the scales on those rare heads up pairings.

By going with that different rule on heads up, that could possibly change the way people run their car during qualifying.

Why not take the indexes from each and set the NMCA index right in the middle? There will be cars in classes that can't run some of the NHRA indexes but are fine in IHRA.... just a thought.

Plus I think two cars in the same class should run heads up, no break out

My NHRA index is 9.30 for SS/AH. In IHRA it is a SS/AA car and I think the index is 9.95. Dyno

I agree with Nick.
It might get confusing.

They could do what Michael Beard did at the Class Nationals and use all IHRA indexes on entries with a similar NHRA class.

It gets even more confusing when the factored IHRA hp is lower than the NHRA hp for the same combo and moves the combo to a different natural class and/or weight..
