HP Adjustments on NHRA.com

Not sure about this but didn't the GT rules at one time only allow for cars that came with a v8 to run a v8. IIRC, that is where the wrong turn happened.

That's precisely my point. If you're going to argue that FWD conversion cars have an inherent advantage, then all FWD conversions cars should start out with a weight penalty. The aerodynamic and chassis advantages don't disappear when they change engines.

Don Kennedy was the pioneer for the creation of the class, originally with RWD cars only.

FJ Smith was the one that brought the idea to NHRA for introducing FWD cars into the class.

If I remember right, there is a .05 disadvantage for a GT car almost accross the board, but not entirely. That from looking at the weight per hp etc. The motors are the same; must be accepted in SS already, then came the jelly bean cars, then some years ago NHRA asked me to request older cars in SS GT as they had many request. This I did and I guess some of the effect was all the older cars are rwd, hence longer wheel bases, harder to make a set of headers cause the stock steering has to stay in a rwd GT car, and a few other things like that. The factoring rwd/fwd, if I remember right was a proposal from SRAC last year. So now the cars (such as my old Duster) don't get hit if someone with a 360 spikes it with a jelly bean car. Michael, your idea of a weight penalty for the jelly beans has merit, but would you use a percentage as opposed to a set weight? Just asking. Same effect, but the administration could be difficult.

wont be long until this is the nhra adjustment posting...

"nhra announces that due to an AHFS infraction all blue 1987 malibu's 4 doors with the 305 combination will be hit with 6 HP"

this is insane and i once again repeat Automatic Help For Slugs cannot and will not ever wotk !

Dunno, I'd posed it as a question myself earlier. It would require some research and common sense. FWD Stockers have a static 100lb weight difference between sticks & automatics. SS/GT Trucks have a weight break for automatics that is "5% or 250 lbs, whichever is less". Again, they'd have to do some research, but would probably end up something like the latter. I don't see that the administration would be much different than what they're doing now, except you wouldn't have a single engine combination with 3 different HP factors!

Jack you are right and what is worse sooner of later the "Man" who is racing will be factored due to skill, money or connections.
Div 6. I again state that making a class of generic cars, with spec motors and trans allowed would give all the people who HATE the factoring a place to race based on SKILL and driving. Everyone else could watch it become the way to race and join or continue to feel inadequate under the AFHS system.(Glad I don't still have one) One legal Mod type car and motor and you cut the cost too. LB/CUBIC Inch in a.......... Chassis. Max cube and carb specs too. I would race again if it happens.
No more injected 305 taxi motor versus a plain old chevy.

Although it will require some refinement like everything else, using Nitro Joe's data, either a weight break or adjustment can be assessed in lieu of playing with the HP factors.

Dick, so your proposal only considers a specific generic model of a car?

Everyone has a like for the choice and brand of cars they like to race in Super Stock.
There are people that like to race a station wagon, others a sedan, etc...

If you are proposing putting a limit and utilizing a specific model of car, the proposal is not going to fly with the racers. The class was built on cars many of us have or drive daily, many of them with nostalgic memories.

So you want to give an Achieva the same weight penalty as a brand new East Texas Cobalt?
