How would you fix the ahfs

Larry Hill · 04-10-2011, 09:22 PM

1. Look at the weight of the cars at the scales and use 100 lbs heavy = .1 subtracted from run, 80 lbs .08 subtracted from run.

2. Use 1/8 mile info E.T. and MPH to help stop the sandbaging

3. Two hits of -1.00 under, automatic hp on Monday, the average just does not work. I.e. 396 /375

1)Wrong........That means you'll be penalized for not weighing exactly your minimum.What do you do about scale fluctuations.I always try to be about 30 # over to make up for scale error.So I get penalized for not taking a chance of scaling light?Think you can get through a race weighing at minimum without being bounced for being light?

2)Wrong.......I'm not a rocket scientist but there is no firm formula for a cars performance at the 1/8th mile.

3)I'm not sure of that.

Larry you need better arguments for the inequities in the AHFS.

I think this AHFS need to not be computer driven... I think weather conditions/track conditions need to come into affect. Also I think if someone runs quick enough to get Hp # 1) take them apart to make sure their legal & 2) hit just that car.... as in if it's an 80 Corvette that get's it hit don't hit everything with just that piston in it! ( read 73-81 350 dish motors) We all know these new cars are fast.....But I think if we leave them run they will beat each other up soon ....just like the LT1 & LS F body cars. ( they may have put FI & Carb cars back together to soon?)

Use common sense to fix underrated combos

Travis Miller · 04-10-2011, 10:32 PM

Let's try this idea.

If an engine combination hits the -1.20 or more under the index twice during a season, NHRA shall then have the right to set the refactored horsepower on that engine combination anywhere it deems necessary.

Example...the 1st time engine XYZ is rated at 345 and goes -1.22, it gets 12 horsepower making it 357. Two weeks later it goes -1.25 under. It is clear after the 2nd time that the horsepower is still wrong. NHRA calculates that the horsepower needs to be at 400 and refactors it there. This would eliminate any lengthy time span in getting the horsepower corrected.

Hi Guys,

I vote for putting all the combos Back to the factory HP ratings...lol

Imagine 66-67 327 275/275 etc.... and let the AHFS fix it!

1) It is completely possiable to have a weather station at each tech trailer that monotors the weather and factors the given weather back to a standard. Example, STP, standard temp, pressure etc. There could be a correction factor at the end of every qualifying round and that is the number to "correct" the times back to the standard. This would take into account all weathers and elevations.

2) Factor new cars and older ones that have been intruduced into the book fairly. Get a rear wheel HP something, if you have nothing to go by. Look at the entire engine specs.

3) All cars that run fast enough to receive a factor shall be tore down. It does not matter if they pass the scales, fail fuel check or what ever they have to be tore down to be determined legal for the factor. Then if they are found to be illegal then they will be penalized...

To me it is real simple.. Hire the personell, give them the equipment and go to it.

I guess ole Larry thinks the 396 isn't fair because it carries 45 less cubic inches, two less barrels and 15 more Hp than his car. He believes it needs more because a few people out of the many have been fast. News Flash! Not everyone with one is flyin, and the two times it went under a second this year have been at a factored track and in very unusual weather conditions in Houston. It was like 65 degrees with a huge tail wind. Talk about a self serving agenda hidden under the guidlelines of "fixing" the AHFS.

Do not publish the triggers so that we can manipulate it.

Ed Wright · 04-11-2011, 10:21 AM

Larry's #1 isn't acrurate. 100lb is not 1/10th on all cars. The more power you make, the less effect it has. Mine, 100 lbs = no more than .08. Higher hp cars is less. Might help, but won't be enough. Probably not .05 with the new Mustangs. Good friend of mine is crew chief on a SBC Comp car, they juggle weight to change classes. He says with their car 100 lbs is five hundredths.
