Good move NHRA.

If FWD GT cars have an advantage over other GT cars, it doesn't make sense to me that only certain FWD conversion cars (ones that happen to hit the AHFS) incur any changes. If there's an inherent advantage, wouldn't it make more sense to have an across-the-board weight adjustment on all FWD GT combinations? While one car may run more *efficiently* than another, an engine doesn't magically produce more actual horsepower when its sitting in one engine bay vs another. (with the exception of fresh-air systems)

It just seems like everything thing they do makes the system more cumbersome, not less so.

One unintended consequence is that they just made it even less likely that my underfactored combination will get HP.

That adjustment is for any FWD GT car that runs that engine combo.

This was done because there are differences in the FWD and RWD platforms for GT cars. It has been in the rules for a long time just not enforced by the AHFS. Plus there are NO FWD GT engine combinations. They run a combo that was in a RWD car hence needing the separate HP evaluation.

Yall know I am a simple man. So let me put it is language (Cajun) that I might understand. You mean dem round back Drumfish looking cars dat used to have a sideways motor that now got a big V8 might not have the lead over a back drive GT fishin car? Need some interpelation here.

Beard. I know you're an intelligent guy. So why is this AHFS change so hard for you to understand? In Super Stock (not GT), you have platforms! A Camaro, is different from a Corvette, which is different from a Chevelle, etc. If one gets hp, it does NOT go to the other! This is now how it works in GT! So use the combination that got hp as an example. If somebody wants to run that combo, or already runs that combo in a FWD conversion car, they now carry 294 hp, or, extra weight, compared to 287 hp in a RWD GT car, which did not trigger the review. So if both cars run GT/EA, just an example, the RWD car would weigh 3040 minimum (287 hp at 10 lb weight break + 170 lbs for driver). The FWD GT car would have to weigh 3110 (294 hp, etc.). Hence, the FWD GT car would carry more weight!

So in Chrysler terms, if a FWD GT car running the 360/275 combo get hp, it would not be given to the RWD Volare with that same combo.

For the last 10+ years, FWD GT cars have been bombing combinations with hp, while the RWD GT cars running those same combos have not, but suffered the effects by adding the same weight and hp to those combinations. Finally, NHRA has realized what all of us effected by this have known all along!

What Michael is saying is make a set penalty for any FWD conversion. However, I am not sure how you would come up with the proper adjustment. You would have to have two good cars (one fwd and one rwd) set up equally with same engine combo, and you would have to test each car with the same drivetrain. Rather then having a Fwd conversion hp for every engine combo, you would have say a 10hp penalty for any FWD conversion. It is obvious that something needed to be done because the FWD cars are obviously faster, but the big question is how much faster are they?

427 COPO's take another hit! One more HP on the 12 & 13's and they are natural AA cars.

Whats up with the 70 GTX 6pak, it's listed twice, at 393 and 422 HP.
