Be sure to check the classification guides and engine blueprint specs too. There are changes that were not posted there as well. For example, 1987 Chevy Camaro 305 190 combo went from 240hp to 245hp and engine specs changed from flat hydraulic to hydraulic roller.,

Re: HP Adjustments are posted
 

^^ this is true.

Re: HP Adjustments are posted
 

Am I reading this correct.....

2011-2014 Mustang Combo with 26 hp off?

Re: HP Adjustments are posted
 

Makes you wonder. I don't see anyone running that combo on Nitro Joes stats. I was told that no runs, no HP reduction will be considered directly by Pat. Guess that rule was just for me.

Re: HP Adjustments are posted
 

According to the rule book, once an engine family receives a hp increase, it is never eligible for a hp decrease.

Stock had 7 combinations get a reduction. 3 of those combos had an NHRA hp rating higher than the OEM rating:

1977 Malibu: OEM = 160-170, Old = 275, New = 271
1969 Roadrunner: OEM = 390, Old = 400, New = 395
1986 T'bird OEM = 150, Old = 200, New = 197

How were these eligible for a reduction?

Re: HP Adjustments are posted
 

I was wondering that too, but I have given up on equal enforcement of the rules or even simple enforcement of the rules as written.

I’m not familiar with that rule, however the Six Pack needed it in C for sure. John Leach must be pleased but I’m sure he wished for more. Beep Beep!

Re: HP Adjustments are posted
 

this is a kick in the nuts,all of a sudden we have 2 engines that are illegal after being built to the rules. And after we make them right we get 5 more horsepower and 60 lbs.

Re: HP Adjustments are posted
 

Not sure about the others but looks like the change in the Malibu is for aftermarket heads only. already 270 for stock heads. Rick

Re: HP Adjustments are posted
 

I was told by Pat C that if the NHRA HP was less than the factory hp it could be considered for a reduction. Most of the reductions fit that, but not all. Curious.Also, the 76 and 77 305 novas both got hit, but only the 77 had runs to cause the hit. They didn't do that to the 302 FFFFords 75-78.

Re: HP Adjustments are posted
 

Apparently neither is the person from the NHRA that reduced the combo. This is directly from the AHFS rule book. "Once an engine family receives a horsepower increase it is not eligible for a decrease."

Re: HP Adjustments are posted
 

Many of those above OEM HP ratings were picked by NHRA officials at the time that assigned a "reasonable HP factor" to the combination. Some of these reasonable assignments were as bad as the inflated 1960s numbers some of the manufacturers assigned. There were some combinations were given as much as 75hp without ever being run. Some needed it others were made into filler for the guide instantly.

Re: HP Adjustments are posted
 

In the case of the reduction I was referring to had the NHRA HP and Factory HP the same before this reduction of 26 hp which was a 10% gift. Pretty big one by anybody's standard.

Pat C told me that no runs will not get any consideration for a HP reduction. This combo didn't have any runs nor was it meeting the other criteria that he quoted you. Makes me question the motive, but they don't care what we think. That is the only constant.

Re: HP Adjustments are posted
 

Paul, That makes sense and I wondered if that was the case with any of these particular combo’s. I figured somebody like you with some historical knowledge of various combos would know.

Re: HP Adjustments are posted
 

I asked for look at 2010 Camaro SS at 400 hp with less lift cam and less compression than 2015 Camaro. Got no response.

Re: HP Adjustments are posted
 

In addition, the engine family must NOT make two runs of 0.650 or quicker or any run 0.850 or quicker during the past two (2) review periods, for the review to continue. Once an engine family receives a horsepower increase it is not eligible for a decrease.
For the ones with more then factoryHP. It's based off increases over the past 2 reviews that are not eligible.

Re: HP Adjustments are posted
 

The '86 T-Bird 302 combo ( 150 hp ) has been 197 h.p. since Jan. 01, 2015

So it's not a reduction

Re: HP Adjustments are posted
 

Could it have been increased to 200 since 2015 then reduced back to 197 1/1/2021? Because the current guide shows the date of 1/1/2021 for the 197 hp rating.

Edited to add: I did a little digging and this combo did get a HP increase at the end of 2018 from 197 to 200.

Re: HP Adjustments are posted
 

According to Nitro Joe’s Stats Nanette Stein was running this combo at Sonoma LODRS and ran faster than -.65 in qualifying and first round. If that is indeed true, how did it qualify for a reduction?

DRC lists the entry as an 89 so I’m not sure which is true.

Re: HP Adjustments are posted
 

The 1989 would not be correct because it isn't in the guide as a 302 150 factory 200 NHRA rated. It would have to be a 1986 as Nitro Joe indicates. From the AHFS rule book "In addition, the engine family must NOT make two runs of 0.650 or quicker or any run 0.850 or quicker during the past two (2) review periods, for the review to continue."

The Sonoma divisional wasn't a mineshaft race so those two runs alone would have made the combo ineligible IF the NHRA followed their own rule book, but who knows why they do what they do.

Re: HP Adjustments are posted
 

That car isn't a 1989 T Bird

Re: HP Adjustments are posted
 

Not sure.

There used to be a line on NHRA's site about the 3 year deal. They have since deleted it.
Used to be a combo was not eligible for a reduction for 3 years after an increase.

Re: HP Adjustments are posted
 

You can see from my link it was increased 2 years ago, but the time frame doesn't matter because this is the AHFS rule regarding past increases. "Once an engine family receives a horsepower increase it is not eligible for a decrease."

That is only one of the reasons why it shouldn't be eligible. The other one is what Drew pointed out. That combo had too many runs -.650 or quicker. There are multiple reasons why it wouldn't be eligible based on the rules as written, but it appears those are only suggestions. Or more commonly referred to by the NHRA as "clerical errors."

For those keeping score, CLERICAL ERRORS .....is code name for Pat Cevengros ....

Re: HP Adjustments are posted
 

If the largest HP reduction annually is 2.25% based on a current year run of no quicker than -0.101 to -0.165 how does the 1962 Pontiac 421/ 405 go from 385 HP to 360 HP. 2.25 % of 385 is, after rounding, is 9 HP not 25 HP. It looks like the 227/ 260 Ford received more than 2.25% reduction. After rounding the power should be 254 not the 234.

I would bet that after the first of the year the numbers will be more accurate.

Re: HP Adjustments are posted
 

NHRA posted 11/16/21 as the cutoff date for accepting reduction requests for the 2021 season.
Thank you!

Re: HP Adjustments are posted
 

Huh, I sure don't remember asking Santa for three more HP!

Re: HP Adjustments are posted
 

Is it any wonder people bracket race?

Relax everyone! Jeez! It’s just typos!

I wish I had known about this combo before. I could have made twice the factory power.

Re: HP Adjustments are posted
 

The ‘69 Roadrunner is for the replacement head. I don’t think anyone is running that yet, but may very well be wrong (didn’t look...).

The factory head is rated at 380. The better combo right now, anyway.
