HP Adjustments on NHRA.com

[Bryan Worner]

Beard. I know you're an intelligent guy. So why is this AHFS change so hard for you to understand? In Super Stock (not GT), you have platforms! A Camaro, is different from a Corvette, which is different from a Chevelle, etc. If one gets hp, it does NOT go to the other! This is now how it works in GT! So use the combination that got hp as an example. If somebody wants to run that combo, or already runs that combo in a FWD conversion car, they now carry 294 hp, or, extra weight, compared to 287 hp in a RWD GT car, which did not trigger the review. So if both cars run GT/EA, just an example, the RWD car would weigh 3040 minimum (287 hp at 10 lb weight break + 170 lbs for driver). The FWD GT car would have to weigh 3110 (294 hp, etc.). Hence, the FWD GT car would carry more weight!

So in Chrysler terms, if a FWD GT car running the 360/275 combo get hp, it would not be given to the RWD Volare with that same combo.

For the last 10+ years, FWD GT cars have been bombing combinations with hp, while the RWD GT cars running those same combos have not, but suffered the effects by adding the same weight and hp to those combinations. Finally, NHRA has realized what all of us effected by this have known all along!

What Michael is saying is make a set penalty for any FWD conversion. However, I am not sure how you would come up with the proper adjustment. You would have to have two good cars (one fwd and one rwd) set up equally with same engine combo, and you would have to test each car with the same drivetrain. Rather then having a Fwd conversion hp for every engine combo, you would have say a 10hp penalty for any FWD conversion. It is obvious that something needed to be done because the FWD cars are obviously faster, but the big question is how much faster are they?

427 COPO's take another hit! One more HP on the 12 & 13's and they are natural AA cars.

Whats up with the 70 GTX 6pak, it's listed twice, at 393 and 422 HP.

It looks like 393 is the factor with the factory head, 422 is the factor with the replacement Edelbrock head.

Is it just me seeing something for the first time or is there an unusually long list of requests in this report?

So NHRA has done it again.

First, Michael is absolutely correct in that an engine does not know what chassis
it's in. The HP factors for straight SS and GT have never made any sense to me, or any competent engine builder for that matter.

Now you want to say it matters if it's a RWD or FWD conversion???

Having been involved in the sport from the inset of GT, (and anyone that was) will remember that in the beginning, the GT cars were considerably slower than the straight SS cars.
Where did the difference come from??
WORK!!!!
These cars were owned and raced by people that worked on their stuff and made it fast.

I suggest the same thing is today with the conversion cars.

Back In the old modified days (yea, I'm old), when you got outrun, you went home and worked on your stuff. No crying on the internet, no emails, and certainly no AHFS.

I suggest the rest go work on their s##t and low and behold, be just as fast.

Well stated F.J.! Very few work hard to make their stuff fast anymore. Bracket racers.

for three years I have asked the 1970 - 402/375 in a camaro be refactored and each time has been not changed. The combo is not correct with current hp thoughts what should be the next step?
