Ford and Mopar Aluminum R/E Cases??

[RJ Sledge]

Looks like the new Mustangs and all Mopars and GM Stockers are the only ones to get to run the aluminum 3d member cases. If you have an older Ford car you can't run an aluminum 3d member, regardless of what is said in the rule book of the last several years. It was legal in 2008 to present, now its illegal. If you have a 2008 Mustang and up Stocker you are ok, but not 2007 and down. If you have a Mopar new or old you are ok as is the 12 bolt aluminum cover for GM.

NHRA in all their infinite wisdom has decided that a 4 year old rule is now not legal if you have an older Ford Stocker.

Really makes sense don't you think?

Not sure why anybody would bother with an alunium cover on a 12 bolt GM rear. The factory steel cover doesn't weigh a pound. It's just stamped steel.

Its for support and strength, not weight loss. Hope you have your problem fixed

Sorry R J. Didn't get that. I don't have enough power to need one. LOL
I can see a stick needing that.

Won't know if it's fixed until Friday.

Well, lets see. I have a magnesium 8 3/4 housing from the 70's, I think that will be legal,LOL. Or maybe the Dana 44 aluminum center from a Jeep will work,. Jack asses!

The ONLY reason I can think that they are doing this for is to prevent the Mopar racers from using the V-10 Drag Pak unit in older cars,as it has a production 9" "aftermarket" rear end.Just a thought.

But to me I don't see the advantage of disallowing any aluminum OE style center section in stock,there is no performance gain.

RJ,

If you have an old Mopar, you can not use an aluminum center section. I guess you can't call it a new rule because they have not added an amendment or change the rule book. They just say that's what the rule means.

From what I have read on NHRA, the Racer Update section, its not legal in anything expect special production cars.

The rules still does not make any sense to me. We are allowed to replace the rear with a same manufacture. What happens if the aluminum is the only one available.

Is it legal if I replace the center section with aftermarket steel? How about if it is made of Titanium.

Ken

I had gotten incorrect info on the Mopars, my bad.
Did you receive any feedback from NHRA on your letter?? I still can't understand how a rule that was over 3 years old now is out the window. What was their thinking on this? Really makes you wonder what is going on, really makes no sense.

This is true. I have made all the phone calls and have gotten the same answer. Not legal in older MoPar, never has been. This is ridiculous, NOTHING is consistent with these rules anymore! Jim

I did not receive a response, but I do know Glen Gray read the letter. At first I thought they were going to let us use it. When they posted the interpretation of what the rule means, well lets just say I was disappointed.

It makes no sense, I can run a C6 with 904 internals, I can run a aluminum spool, but I can not use something that has no performance advantage.

I will have to to invest a $1000 plus to replace the aluminum center sections that i have been using for the past three years. I don't think NHRA realizes how many racers this will affect.
