Re: We need a new "instant" trigger!
 

Mike, maybe I didn't make myself clear. I'm OK with the -1.40 number I just don't think that the 3.25% number is enough. What I'm looking for is something like 7% or even more.

Re: We need a new "instant" trigger!
 

Billy, if a certain killer car starts out at about 400# heavy, even 7% is not going to do the job.

Re: We need a new "instant" trigger!
 

Ok, now I see what you mean, and what you want to do. By "trigger", I thought you were referring to the -1.40 under mark. At 3.25%, an A/SA 427/425 would get hit 14 HP. Bob's car, at 180 HP in U/SA, gets hit only six. Which, on the surface, doesn't seem fair. Yet, the the U/SA gets more weight added (120 pounds vs the A/SA's 112 pounds). At 4%, it would be 18 HP and 144 pounds in A/SA and 8 HP and 160 pounds in U/SA. 5% is 22 HP and 176 pounds in A, 9 HP and 180 pounds in U. I suppose if one were to want to increase the rate at which a combination receives HP, they would go for a higher percentage (4 or 5%). Would that be too much or not enough? You might poll 100 racers and get 75-80 different opinions and responses. Maybe we need a poll posted on here to see what other's opinions and thoughts are. ME personally, again, I wouldn't change much. They could always make a small change, maybe up to 3.5% and see what that does. BTW, did you get your book in the mail, Billy?

Re: We need a new "instant" trigger!
 

Mike, yes I did and I'm sorry for not thanking you sooner.

Re: We need a new "instant" trigger!
 

Mark, you're right but it would help to bring it in line twice as soon without obsoleteing a combo overnight.

Re: We need a new "instant" trigger!
 

Billy-- Using your 7% would be harsh at best -- for example our LS1 Firebird is rated at 364 hp -- 7% would be 25 HP at one shot -- or in C/SA trim-- a 9lb class-- thats 225 lbs at one time -- ouch ! ! ! One fabulous day at Atco or somewhere with good air and your toast -- no thanks ! ! ! You're trying to reinvent the wheel in a day .......

Re: We need a new "instant" trigger!
 

Maybe I'm taking this thread o/t, but here's some ideas for getting some of the soft hp ratings in line:
(I'm not advocating any of them. Just tossing them out)

Implement the AHFS adjustments 4 times a year.

Take away the "free race " during the data period.

Include altitude tracks in the 1.15 and 1.40 trigger (under the factored index)

Lower the "high side " trigger to 1.30 under.


Trouble is , if you implement all the above, you'll have alot more racers making 1000 ' runs in qualifying, and "bracket racing" in class and heads- up runs.
Not good , if you ever want to build spectator appeal for S/SS

Re: We need a new "instant" trigger!
 

Billy maybe they should institute the "Artie Leong" rule 8.5% in one shot. Seemed to make a lot of people happy at the time.
Lets see now? 425 HP times 8.5%. Thats 36 horsepower in a 9 pound class thats 320 pounds. Sounds like a plan to me.
To be serious. Billy whatever the number guys are still going to play games. And run in braket mode. I just think anyone the goes fast enough for a instant hit sound be torn down. And nhra should use corrected density altitude. For their books We all know running 115 under in a mineshaft is easier than running 115 under at 3000' density altitude.

Re: We need a new "instant" trigger!
 

how about this.

1.400-1.424 under = 3.5%
1.425-1.449 under = 5%
1.450-1.474 under = 7%
1.475 under or more = 10%

or 1% for every .01 under 1.40

Re: We need a new "instant" trigger!
 

I think Chad is on to the right idea. Make it multiple trigger points each with a larger hit on the horse power. I would maybe spread ot out alittle more that what he had. Maybe an extra percent per tenth or some thing like that.
In the case of some thing like a 2:00 under run it should be hit no matter where the run takes place. weather it was a factord track or not.
