Displacement Rules
Anybody else think that there should be some kind of breakdown in each class with regard to displacement? There's a huge size disparity between a lot of the popular motors being run, and for the most part there's no penalties (or allowances) made for running toward the extremes of that range. Back when most of the motors being run were between 1.6 and 2.0L (with the ocassional H22) the playing field was somewhat level. But now with all the new 2.XL motors coming out, I think there should perhaps be some kind of differentiation between the smaller engines and larger ones, maybe similar to the old IMSA GTU and GTO classification. If not splitting into two seperate classes, one for under 2.0L and one for 2.0L and over, then maybe weight penalties/allowances? What do you guys think?
its a fair idea... but couldn't it get difficult to confirm or prove ones displacement? i mean i guess for the most part you could tell by the block, but with sleeves and massive overbores it could get hard, and possibly cause disputes?

No you do it on the honor system. If some one protests, then you pull it down.

Or you could let the displacement be what ever the builder wants (except for deckplate) and require them to run a restrictor plate on the inlet of the turbo.
Nah, thats too much like NASCAR. (hehe)

sounds like a good idea, but right now that would make too many classes that probably wont fill up. maybe in a few years when the class are overwhelmed and the playing is more competitive.

There are ways to get arround that
Thats why NASCAR tears you down
and Bore and strokes ya

The only true class that is ready to be split into two class...not by max displacement or weight, but by e.t.'s....is the ALL MOTOR class
...divide the class between 10.99 and quicker and quicker and a 11.99-11.00 class. All motor is the only class with more cars than thier are slots. Hardly ever a day when its not filled.

Yeah, I agree there might be problems fully populating classes if they're divided up depending on your engine size. But what about the idea of adding weight penalties to cars with larger displacements? I mean, in some sanctioned events, what's to stop somebody from running a 3.0L 4-cyl?
hasnt anyone ever seen the NIRA/NOPI rules. its says .7 lbs per cc. thats about the most equal way of doing it until they say max is 2.5 and weighs 1600lbs. then everyone will have a 2.5 or close and weigh 1600lbs just like the pro stock guys do.
I like the NDRA rule.
And Pro Stock is not ready for a class split at all. If you can't qualify...go back to the drawing board. Thats part of the challenge. Not everyone should be handed a qualifying spot in such a competitive class.

i think he is reffering to all-motor when he says prostock.. not the domestic pro-stock.. i belive there has never been that small of a spread in the import world.

no i was reffering to the domestics. where the rulebook says like 2250 lbs and 500 ci. the imports arent ready because theres to big of a difference between manufactors motor sizes. but i think in 2-3 yrs it will be similar to the domestic rule.

Personally I believe in the golden rule..... "Run whatcha brung slapnuts"......... Then get out and build it bigger and better if it still aint enough to win with..........
