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.

Re: Ford and Mopar Aluminum R/E Cases??

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!

Re: Ford and Mopar Aluminum R/E Cases??

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.

Not sure why we have to keep the HVAC controls in the dash either. Guess they feel like they have to draw lines somewhere.

Mark your kidding aren't you? If not, let me enlighten you, back to back there was no difference.

I guess being a traveling pro like yourself, $800 is just a drop in the bucket.

Not hardly Ken. $800 is a fill up of diesel. As a traveling pro, $800 is hard to come by!

If there is no performance gain, then what's the beef?? Run the iron one, it's cheaper. As for Ken buying the aluminum pieces and there is no performance gain, why do it? The aluminum housings are more hassle and more expensive.

Re: Ford and Mopar Aluminum R/E Cases??

Mark, my statement about a traveling pro was misinforming, just as your statement was. I figured it was well deserved.

Dwight, I don't think you realize that Mopar was paying contingency, this is one reason why Mopar guys were using them.

I like them because it makes the gear change much easier, there is no hassle with aluminum. As far as being more expensive, they are the same price, unless you put a stock one in.

When I got my car back it already had an aluminum center section in it, and came with a spare. Its not just a matter of choosing steel or aluminum, the money has already be spent by me and many racers.

The rule is misleading and needs to be changed, its that simple.

Re: Ford and Mopar Aluminum R/E Cases??

Anytime you can move weight around there is an advantage somewhere. The closer the car/suspension is to optimum the more the little things matter. I can move 5 pounds from side to side and tell a slight difference in the leave. That really surprised me back about 15 years ago when a chassis builder told me to buy a good set of scales and taught me how to monitor the car's shocks, springs, etc. and keep records.
With that said, it may be more important in a 4 link car than a stocker chassis but some allowments in stock chassis bars are pretty advanced these days. It also brings up the point of "why did it take this many years to clarify a rule (and make it available in easy to understand terms) that many have taken advantage of and set records, won races, went thru indy tech with"? I wouldn't have thought twice about Ken's center section legal or not after reading the wording in the rule book. And I have personally seen MUCH greater infractions get told "have it fixed by next race".
Some would be shocked to see the many uses of stellite and titanium in some race cars. Remember the term "stronger than steal....lighter than aluminum.

And with what is being allowed as stock in todays factory produced "race cars", i really don't think the new clearer ruling is exactly right. But thats just my opinion.
