Challenger Drag-Pak Transmission
 

Just got a call today our Drag-Pak is ready for pickup. (Finally , Ive been hearing "Next Month" since Oct of last year)

Some questions for the guys who are running them.

Ive talked to everyone building them, MPR, the trans guys around the planet....my brain is going to melt.

Im going to of course run a Dana 60, Gears well not sure yet Ive got some ideas. The rest of the setup probably done by MPR.

The tranny is where Im really at a loss.........I will be class racing with the car, but also bracket bombing the local tracks.

Protrans, Proflite....yeah yeah yeah.....but for now until Dec I need something asap....(Noone can get me one built till then)

Is my best bet going to be running a 727 so Im all set up for the protrans or runa 904.

Considering this is a "Temporary" transmission. What am I going to best be closest to dialing in for the long run with ?

Ive got mixed feeling about either temporary solution. The 727 makes me flinch because of weight , both physical and reciprocating.

The 904 2.74 ratio makes me smile, but the case difference makes me have to set up shafts twice.

What am I looking at losing ? A couple 10ths ? What about between the 904/727 ?

ATI is working on a whole package but it wont be ready till next year.....TIME is driving me nuts....Im not looking to set world records at this point, but Id like to be competitive.

Also what are you guys running as far as stall ?
If I could row a manual Id seriously consider it at this point.

Some help on just pros and cons would be great.

Thanks

Chris

Mopar and I believe Turbo Action did some testing in the mid-'70's and they came up with .15 difference between a 727 and 904 built the same way with similar converters. The difference would be less today because you would save more weight in the 727 with custom aluminum parts in both.

Talk to Mike Roth at MR2 Performance. He finished Randy Warfords 003 drag pak. At Indy he ran 10.01, I think Mike can help you. PM me for his phone number.

Be a man and put a stick in it.

Re: Challenger Drag-Pak Transmission
 

That would be cool, however I don' t think anyone has run one of these with a stick yet.

What the hell would I even run....aaaaaaaa......I hate transmissions....thats the old mans area, mine is breaking them

Call Scott at Jerico and order a 5 speed. Call Rob at Advanced clutch. Done deal. :)

Time is driving you nuts? Welcome to the club! If your just picking up the car from MOPAR in October, unless your a super-hero assembler or have a dedicated crew with nothing else to do for 60 hours a week, there's no way you can be racing inside of three months. I'm assuming paint, wiring, blue-printing, etc. If I'm wrong, go for it and good luck.
But if I'm right, after reality sets in, you should have plenty of time to get the right trans, whether it be an auto-trans (Pro-Trans) or manual (Jerico, G-Force or new liberty soon to be released). Do it right the first time. Having such a car that will be under a microscope by everybody at the track does not deserve second hand parts.
And as mentioned, call Advanced. They'll set you up with the Bellhousing, trans and clutch. Like I said, do it right the first time. The fact (?) nobody has run an '09 Challenger with a stick means nothing. If your the first and get it down the track quick you may get more ink and therefore maybe a sponsor.
Have fun!

I think I would put a metric 200 in it.

Lol...well unfortunatley youre sorta right....I have no life other than my shop at the moment. I spend 80 hrs a week here and when I have free time and nothing to do I end up here, its like a life magnet :) And I do have a good crew, and well I moved all my other cars into our other shop yesterday so there is no other item to concentrate on here (i can be a bit add when it comes to my cars)

I do agree with you on the stick thing, all of it, and while originally it was half joke half tounge in cheek, its growing on me.

Im at total loss on that side as to what ratios to even consider, its been more than a decade since I ran one, and it was a lethal combo but it was dumb luck that one went together right (sbc and wide ratio muncie)

Ill take your advice and give him a call.

Thanks
