I suggest you read this again, and pay very close attention:
Don't get me wrong. I like Jeff Teuton, I respect him, he's a great guy, he's one of my favorite people, I always enjoy seeing him at the track or at a trade show, I always enjoy talking to him, even though we often do not agree at all. The fact that we disagree completely on this subject does not change that at all.
You will not end up with a lighter car under his HP factor reduction proposal. You will not end up with a faster car. You will end up with a car that runs further under the index. In a lower class. Temporarily.
Jeff asked for an example, so here is one very similar to what he started with.
Take a current, very popular combination, the 1969 Camaro 396/375 with aluminum heads. Currently, this car is a natural A car, with a HP factor of 405HP, and a curb weight of 3337 pounds. Currently, it is at 8.24 pounds per factored HP, which being between 8.0 and 8.5 is a natural A/SA. So, Jeff Teuton is proposing to take 10% off of the current 405HP factor. As such, 405HP, minus 40.5HP, or 10%, equals 364.5HP, which rounds up to 365HP. Your curb weight remains the same, 3337 pounds. So, 3337 pounds, divided by the new HP factor of 365HP, yields a factor of 9.14 pounds per HP, which being between 9.0 and 9.5 pounds per HP, makes it a natural C/SA combination, you can run B/SA, C/SA, or D/SA . So, your A/SA 1969 Camaro, that runs 10.0, now becomes a C/SA 1969 Camaro, that runs 10.0. Your index changes from 11.00, to 11.40. So, where you were running 1.0 under the index, now you can run 1.4 under the index. And when you run 1.4 under the index, the next Tuesday, you get a nice little gift from NHRA, of 26.46HP, rounded up to 27HP, putting you right up at 392HP, well over 1/2 way back to where you started. And we all know the combination is capable of 1.1 to 1.2 under right now in a fast car. So when someone in a C/SA 69 Camaro 396/375 aluminum head car runs one all the way out, well, I think you know what happens then.
Now, I'm not seeing the real gift here. You pretty much just drop a couple of classes, so you can run further under. So now, you have to sand bag, drop at 1000', or what ever you need to do to kill over 2 tenths, (that's if you started with a 1.0 under car) just to avoid an instant 3.25% hit, and hope everyone else does the same, to protect your combination. And they won't. The AHFS is going to get you, and hang that HP back on you, either by instant hits when someone wants to or needs to go fast, or by constantly hitting the trigger for an adjustment for the average.
He's not proposing to reduce your weight, and make your car faster, he's proposing to move your car down 2-3 classes so you can run 1.4 to 1.6 under the index. Which, since you will NOT be immune to the AHFS like the factory cars are at some races, will earn you that same HP right back.
You're car is not going to be lighter, so it breaks fewer parts, and goes faster. Your car is just going to move down a few classes so it can run further under the index. For a very short while, until someone with your combination starts getting you some nice gifts from NHRA on Tuesday mornings.
If you think that's a good solution, well, go right ahead and support it. I guess if you want your good running A/SA car to become a real fast C/SA car, it works okay. So long as everyone protects it. From where I sit, it looks like worse than where we are right now. This is a very short term temporary solution. It has zero effect on the factory race cars that now cause the problem. Zero effect. Nothing changes for them.
If anyone successfully convinces NHRA to do anything about the problem, and that in itself is a huge "if", they're going to do one thing, one time. If it doesn't work, oh well. So, be real careful what you ask for, or what someone asks for on your behalf.
