If you have a Rockwell, do you have an OPEN driveline??
that is the question that has been posed to me.
lets say USA-EAST permitted a ROCKWELL rear-end in the Pro Stock Diesel class (in order to save breakage issues and additional cost issues).
is this possible without going to the open driveline.
your thoughts are important....

I dont know if i would word it this way "in order to save breakage issues and additional cost issues". The reason being that the rears breaking is saving the transmissions from breaking, put a rear in it that wont break then there is going to another weak link. Once the rears stop breaking then you can add more power till the trans breaks and when that goes alot of time so does the motor. In my opinion your are just prolonging the Inevitable and that is open driveline at this point. Also in the eyes of every org. that put on pulls this would still be an open drive line truck because the rear didnt come in a 1 ton or smaller pickup.
I have no dog in this fight but if you open the drive line i will make some of the hooks if you dont i will run some place else so i am just putting in constructive criticism.

i also would like to say how close some of the pro stock guys are with a stock drive against the open guys with no expence spared.i also believe if starting with a rolling chassis the cost is about the same if you find deals and do the work your self.but who am i?just some thoughts

Just adding a Rockwell F106 will not help me. The trouble is gear ratios. The most common 106 ratio's 5.80, 5.83, 6.20, 6.80, 7.20. Most Dodge pullers use the 6.20 setup because they can get 6.17 front gears. But I can not get a gear set that matches like that for the front of my GM. So in order to go Rockwell rear I would need to swap out the front end to. It can be done but there is still another issue. Final gear ratio. With the ratios available in a Rockwell I would need a dropbox. The Stock Transfer cases strong enough for our trucks all have 2.72 ratios. Combine that with 6.2 in the Rockwell you get a 16.86 final drive ratio. That is way to high for a Dmax. We need to be around 13. We need a transfercase reduction of 2.09 With a Dropbox we can easily do that and we can fine tune the ratio quickly and easily.
I dont have a problem with opening the the driveline rules. I will not be able to step up to open driveline to 2010. After all I spent on bringing the OEM driveline up to snuff I can not afford to go open this winter.
Even if I could it would be tough because of the added height of switching the front and rear axles means the truck would not fit in my garage anymore.

I looked into it last winter before upgrading my stock stuff. Basicly the same money. I wish I only had $3000 in my rear axle that I just broke.

For myself transmission is the weak point. I don't feel as though the rear end is my week point.

yea,i was just throwing that number out.christ,you can buy a military rear for call it $600.breakproof axles and spool for $3500.machine work on spindles $500.done and not ever touching it again.but even dodge guys would need to use a dropbox to stay on the low side of the t case

Why not just spin the fronts faster like the mud racers do?

Because a mud racers doesnt weigh 8000 pounds. It will break the teeth off the ring gear from dragging the rearend around. More then a couple points off and its hard on stuff

I would say all or nothing !!! Someone somewhere has to hold the line on rules and slow the progression down. The dang 2.6 class is way out of line and it gets worse the higher up you go. I would say stay with oem drive line to hold the class back or empty the deep pockets of the big shots till they detune and run a resonable hp that will keep there driveline living. If you give into driveline this year they will want to open up turbo rules next and then you have a two class's and the only difference is the tires....... Cut pullers or street tires because both trucks will have the same motor under the hood...

Both classes have the basicly the same engine rules now. PS can run more tire.

well you see,the Ntpa is adding a prostock class,running the 3.0 turbo,open driveline,if you,fullpull would have open driveline,you could, an can build a truck an run all across the country with the same truck with out changing a lot of stuff,to me that would make more sence,because you would get more pullers,and no you don't havto change the turbo rules,leave it unlimitted single an 3.2 twins,just like NADMs....it would work great,trust me,

Rick, I was talking to Gene a while back and he said that one concept that has been suggested before is to make a several year progression toward open driveline by first allowing the non-OEM axles first and then a year later allow the drop boxes and the rest.
This would allow some folks to work into it instead of just jumping off a cliff. For example it would allow Scott Blair back in the class (unless he changes his current setup over the winter).
John mentions the gearing issues and really that extends to both Dodge and GM. If you go Rockwell F106 then you'll really be wanting the drop box to get a decent set of ratios. For the Dmax this would necessitate taking out the whole front suspension and driveline and putting a solid axle up there. This is fairly popular with the offroad guys but it is a big project and is fairly expensive. A lot of Dmax guys would see that as a "point of no return" because you're cutting some stuff off the chassis to do it.
IMO PSD needs to head to open driveline IF you are going to keep it unlimited single turbos.
If you were going to go the other way and start limiting the charger to 3" or whatever, then stock driveline with expensive guts will probably work as it has been.
IF PSD goes open driveline then I'm out of it for a couple years minimum for cost reasons.

How does putting a Cummins in a GM solve front end issues?
