NHRA Announces Changes to Class Guide

[Frank Castros]

Factory Experimental within Stock Eliminator?

I'd almost bet that any type of FX classes would wind up in SS. It seems like SS has become a "dumping ground" for classes that don't exactly fit in Stock or Comp.
I agree with Alan about 6 and 6.5 classes in Stock. A 9" tire would be a scary ride and 10.5 tire puts everyone else at more of a disadvantage.

If they are put into their own class then it's what we've been asking for the last two years. Maybe NHRA has finally seen the light with stock car counts constantly dropping. I hope this includes the lower class cars also. Their numbers are growing. My only concern is that they combine stick and auto cars to make room for the new classes which opens another can of worms since so many combo's have different HP. Many think that the auto cars can consistently compete with the stick cars but a three speed auto with a converter which loses HP going through the converter will not outrun a 4 speed stick when all things are equal. I ran a stick for many years way back when just because it was always faster.

Transmissions and converters are MUCH more efficent today than "Back When" until you get into the lower and FWD classes. nNly problem is in todays S/S classes is they are now allowed clutchless stick transmissions.

With a new rating of 491 HP that combo is now only about 250HP under-factored.....so that should only be about 2 more years before they fit where they belong.

Simple fix bring back the fuel injection classes with some higher classes.

Mike,
If we read this correctly they expect a car with more modifications and 170 lbs less wt to run just .18 quicker?

Well it did it with no modifications from how he ran it in stock.

Chad, seems I hit the go button and wiped out a line without trying. Was going to ask if it weighed the same or the 170 lbs. less. Have some non racing engineering friends interested in this because of the vast differences in HP and WT being described. To clarify you can only add enough wt to move up or down a class (as in you cannot be too heavy and run slower than you would at max class weight using the class numbers) but in AA/SA many of these cars have over 500 lbs of weight added? They want to know if there is a rule on where the weight is added. Must it be split to 50/50, etc.? I thought NHRA removed the nose heavy % requirement many years ago.
Thanks

6.0lb Stockers ... like a 427 Cobra? Unfortunately that wouldn't run with the CJ's and Drag Paks either but it'll be interesting to see how deep in the 8's a Stocker will go.
