DP rear axle assembly - Page 2

The TI sheet for the 2011 V10 and the 2011 426 allow a 9" rear axle. This is what NHRA approved. Really pretty simple. The TI sheet is what manufacturers submit to NHRA for approval for specific approval of a car/engine combo. Anyway this is for information only. Do what you want.

I agree with everything you have written. The old techman in me is just trying to wrap my little brain around how this then applies to the rest of the Mopar fleet. It would seem that once the Strange9 was submitted on the TI and approved it then became "another from the same automobile manufacturer" as the rulebook requires to then be allowed for all Mopar stock racecars. Much the same as Mike described the Dana. Both built by an outside manufacturer and accepted in a car (Strange9) or cars (Dana) by NHRA and therefor would seem to be accepted in all Mopars as the Dana is. Again, where is my logic flawed?

This issue needs to be clarrified by the NHRA in the published rules. When I started on my 2010 Camaro, I was told that I could not run the 9 inch. I have also been told that a 12-bolt would be OK in my COPO.

This is not rear axel related but since we are talking "years" --

Did MOPAR/NHRA authorize the lift off hood with a scoop to accommodate the 426

It did not come on the 2011 V10 Drag Pak

They must have ,,, LOL

So we cannot just swap out the V10 without changing the hood - could loose some weight

Nobody has any flawed thinking, but from NHRA, that is what is accepted. The 9" was specific to the V10 car and now also to the 426 car. NHRA has not accepted the 'any corporate' yet for the 9" in other cars. I was just presenting what I have from NHRA after a racer complained to me about the subject and I inquired. I would hate to see one of my fellow Stock racers show up and be turned away especially at Indy because of this item. It's a whole lot easier to address before you leave to go. Pretty simple.
