2011-2014 Mustang Combo with 26 hp off?
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.

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?

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!

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."

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.

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.

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.

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

So it's not a reduction
