08 Ram Diesel Dry lakes racer build
 
I thought it's probably about time to do a build thread on our 08 Ram 2500 land speed effort.I'll post up what we've done so far along with any pictures I have.If ya have any questions about the build let me know.
Just over a year ago I decided to build a diesel land speed racing vehicle,aiming to go fast and hopefully get a record in the class maybe even go 200mph.
First job was to find a good donor vehicle after searching around we found the 2008 Ram 2500 at a salvage auction,with a wee bit of damage caused by the truck hitting a sizeable elk.

As soon as the truck was delivered from Arizona to Colorado ,I removed all of the damaged sheetmetal radiator intercooler and condensor.

I hunted down most of the parts to fix the truck on craigslist and local ads,finally getting the truck back in one piece except for the bed.

A used bed was found,I then sent all the miss matched parts to my buddies bodyshop for a lick of white paint,here's the truck after getting the bed,bumper and fender painted.

Next on the list was to gut the interior in preparation for the Roll cage.Nothing quite like pulling the interior out of a perfctly good truck!!

S&W race cars had a basic 10 point cage on cad file for the truck,so I ordered up the cage as it would be a good base to start with.Here's a picture with the fist of it welded in.

More on the cage later!

To go really fast,the truck had to come down in height,the only problem is, nobody makes dropped spindles and such for the 3/4 ton 2wd dodge.So this was acheived by modifying a set of mcgaughys 1/2 ton dropped spindles by reaming out the bottom ball joint hole to accept the bigger 3/4 ton ball joint.The top ball joint is the same between the 1/2 ton and the 3/4 ton.test fit a new 3/4 ton ball joint into the modified deropped spindle.

Then fitted the spindle to the truck.

The stock AAM 8 lug rearend was removed from the the truck and a winters xtremeliner quickchange was put back in its place.This rearend comes with a 2.0:1 ring and pinion,then by changing the spur gears ratios from 1.2:1 up to 3.33:1 can be achieved,with a 21 total possible ratios.
If ya buy all 11 sets of spur gears :i_rolleyes:
Here's the xtremeliner quickchange when it arrived.

When the quick change was put in we set it on top of the springs using a set of new spring perches 'axle flip' style I guess.We call it a spring under setup.
Here's the axle in its new home

Here's the truck after the axle flip, it lowers the truck a bunch!! Its sitting on a set of 20 inch steel 1/2 ton rims and tires.

I cut also cut a full coil off each front spring to further lower the front end.

Time to start working on the driveline,I didn't want to tear into a good low mileage engine,so another 6.7 cummins engine core was found for cheap,it was seized up from oil starvation/lack of maintenance.The good stock engine will be sold later to recoup funds.
I tore down the seized 6.7 and found 2 rod bearings were seized onto the crank.I managed to get the stuck rods off the crank.I used muriatic acid to desolve the bearing material off the crank.
To our amazment the crank wasn't damaged and only needed a polish to make all the bearing surfaces good again.After washing the block in the parts washer,the bores were checked and looked pretty good and finish honed at standard.
The motor was put back together with some different stuff to stock.The head was ported and polished with bigger valves fitted,O ring lands were cut in the head and the block.The stock intake plenum was cut off with the bridgeport and a Hellmann performance sidedraft intake fitted.Rods, pistons, bearings, valve springs, oil pump were all cryo treated.
Here's some pictures of the the motor going together.

Wow, real cool thread here, thanks for the picks and sharing your project with everyone. Be keeping an eye on this thread, great work, gonna be nice to see this completed

UNBROKEN 09-13-2012 08:53 PM

Nice choice on the Hellmann part....make sure you spell his name right in any press stuff you do, he gets pissy. LOL

Joe is a very good friend of mine and heavily sponsored my last truck, in fact the Cummins conversion in my F250 was done in house at his shop. He's gonna be doing some work on my Ram R/T too. I know Zach Hamilton well also, and probably anyone else in the diesel industry you may need parts from.
I don't know how deep your contacts are in the diesel world but if I can help in any way just let me know.
I also know a few people who have done diesel land speed projects...I can get you in touch with them if you aren't already. Never hurts to have as much info as you can get.

I'll assume you're tuning it with EFI Live? How fast are you gonna turn the motor? Gonna run a Gear Vendors unit? And most important....did you put a real set of rods in that 6.7? Lord knows they don't like any power put to them. lol
Also...are you on CompD?

bigtim44 09-13-2012 11:09 PM

I'm kinda new to the diesel world,Joe was very helpful with the intake.Thanks for the heads up on the spelling ,I'm terrible for that.
The motor has polished shotpeened and cryo'd 12v rods in it,the cracked cap rods make good paperweights!, also has fat pushrods and 110lb valve springs(cryo'd) and a hamilton cam.
The quickchange rearend has a 2.0 ring and pinion in it, that with the 6 speed should get me the legs I need.I was estimating turning the motor to about 3800 to 4000.I'm using the H&S mini maxx with the full tuning capability,very similar to efi setup.I'll have to get over to comp D,although I thought those guys are pulling sleds.
Cheers
Tim

We have a section for sled pullers...but we started it for everything. We're big into drag racing and have sections for land speed and alternative diesel motorsports. The biggest names in diesel are regular posters there.
I'm one of the owners...we started it back in 06.
Swing by....I use the same name there.
Your build would be a hit for sure.

bigtim44 09-19-2012 11:41 PM

Thanks again,I posted up some pics and info in the alternative section.
