It all sounds pretty fair to me. I especially like the fire jacket rule.

I do have a question though, this -"All classes may move up or down one class from the original classification" What is our Volare's original classification? Are they saying if it is originally classified as an I car that we could only run H, I, or J?

When are they going to put the divisional schedules out?! I need to plan our schedule.

Chip THELEGEND Johnson · 11-09-2007, 03:31 PM

I guess NO button rule in IHRA?
I'll bet not many records set either.

i think it means whatever class you claim to be in that your car fits in at the first race. so if scott runs I/CM at the first race of the year he can move to up to H or no lower Than J for the season... or if he ran J the first race he could only move up to I or down to K at any other race...i think

What about the new HP for the -1.600 pass at Rockingham, if it were a Ford it would have been changed before the race was finished. It took them about 12 hours to give me hp after i went -1.31 under. What abunch of crap. Atleast NHRA sticks to there system

My interpretation of "original clasification" is the car's "natural" class.
Different versions of the same car, like a regular 1978 Volare compared to a 1978 Super Coupe Volare.....the Super Coupe Volare will weigh more because of the extra spoilers, flares, etc. After doing the shipping weight/engine HP math, the heavier car may "naturally" fall into the next slower class.
i.e.: regular fits "I", Super Coupe fits "J". So the regular Volare can be weight-adjusted to run H, I or J while the Super Coupe can be weight-adjusted to run I, J or K.

To get out of those classes, one would need to change the car to reflect some of the differences within the model lines. But it usually wouldn't be more than one class difference.

I'm also not sure on what the crate engines are suppose to use for the engine in the NHRA classification guides. It once was the largest small block or simply largest engine used in that line of cars as a baseline. In other words, a 360 crate motor combo would use the heaviest 360 shipping weight, not a 318 or 6 cyl. shipping weight. (Unless, for example, a 6 cylinder was the largest engine available in a particular model, like a "Feather" Duster in 1976.) But good luck trying to get it that light!

Using a big block in a car that wasn't available with a big block would still use the heaviest engine combo in a given model line, like a 360.

Double-check with tech to be sure.
Hopefully Duane Eiskant will be back to clarify any questions.

As a natural I car, you can run H, I, or J. That wording was actually in the 2007 rulebook, so I'm not sure why they put it in as a revision.

>> What about the new HP for the -1.600 pass at Rockingham

Rockingham was the last race of the season. I'm sure they can get the new HP on it before February.

>> It once was the largest small block or simply largest engine used in that line of cars as a baseline. In other words, a 360 crate motor combo would use the heaviest 360 shipping weight, not a 318 or 6 cyl. shipping weight.

That's wording that *should* be in the rulebook but isn't, and I never have seen it in there. Until they do so, claiming different engines and thus shipping weights could get you into different classes. It *is* specified in the rules for Super Stock Production.

I wonder what the Indexes will be like for the SS Modified FI classes. Should be comparable to the carburated ones.

Now thats flat stupid. You think the records page is barren now, wait until next year.
What are they trying to do?
Save printing ink or band width?

Michael Beard · 11-09-2007, 08:16 PM

I think they don't want championships decided by record points. It's happened in the past. I wonder if they could come up with another reward for record setters, like contingency, gaskets, discount on a race entry? I wonder if when they do set records now, if guys will flat run 'em on kill, since there's no need to 'volley' a record back and forth for points?
