New Tricks For An Old Dog - Engine Mods 3.0

[Guest Post by: Chris Burandt]

Now we're talking!  Motor got put back into the truck with a fresh head gasket, ARP head studs and a sweet looking set of ATS manifolds and up-pipes.  Now the fun begins.  Over the next couple days the plan is to get the compound turbo kit installed.  For turbo's, ATS is going to be using the stock charger with their Aurora 7500 which will create awesome response on the bottom and tons of air up top to fix my high exhaust gas temperature (EGT) problem.  It was so frustrating to me with my previous set up that I had tons of power but no way to use it when pulling up the passes because of excessive EGT's.

With the lack of air we have up here in the Colorado high country I'm so excited about compounds!  All this talk of not being able to get a truck with compounds over 1200 degrees has got me smiling.  I've seen 2000 degrees on my current set up!!!  YIKES.  Bring on the air!!

Chris at ATS mounted up the Twin CP3 kit.  After talking with Clint Cannon, the owner of ATS, I really like what the twin CP3 kit brings to the table.  Even though we're going to be running stock injectors for this towing set up the extra fuel provided by the twin CP3 kit not only maintains desired rail pressure at all times but it also makes the truck run way smoother.  What I also like about this kit is it allows me the option to go bigger in the future with my injectors or a more aggressive EFI live tune as well.  Oh and that billet pulley that drives the second pump looks way cool too!

 

My wife actually told me I was pathetic when after I signed the papers on this truck. I only made it the 17 miles from the dealership to ATS's shop to get the first modification done.  I originally bought this white beauty with 80,000 miles on it and I new 2 things as soon as I drove it off the lot; One was that I couldn't leave it stock, and two was this poor truck would have a trailer behind it 75% of the time.  So it was a no-brainer to me to have the boys at ATS throw in one of their big bad purple transmissions with a Five Star Torque Converter and Co-pilot to handle any load or amount of power I could throw at this thing.  To date it has been the best modification I have ever done to the truck.  It's funny when I get in another diesel and drive it around, especially a modded one that doesn't have any tranny work, how much more solid mine feels than the stock ones.  What a difference!

Can't wait to see the compound turbos next!

Co-Pilot For 6.7L Dodge Ram Solves 68RFE Transmission Issues

Co-Pilot For 68RFE Transmission

ATS has released the most advanced version of the Co-Pilot Controller to assist the durability of the 68RFE Transmission in the 6.7L Dodge Ram Diesel. This truck is capable of impressive power and performance and serious towing weight, but has been lacking in the transmission longevity department. This new transmission system uses computer control to govern hydraulic clamping pressure and shift /lockup strategy (similar to the Allison Transmission in the GM Duramax Trucks).
The combination of mechanical limitations and factory computer programming has left truck owners who are towing heavy loads or tuning for improved performance with a void and in-need of an aftermarket solution. The Co-Pilot Controller for the 68RFE Transmission plugs into the OEM electrical harness and monitors the load being placed on the gearbox.  The hydraulic pressures, shifting, and torque converter lockup strategies are modified to prevent the pressure from dropping to an unsafe level and therefore avoiding slippage of the internal clutch packs. Many issues stem from hard acceleration damage that occurs to the 'low-sprag' or 'low-roller clutch' inside the transmission. The Co-Pilot is programmed to engage the low clutch pack to distribute the torque load more effectively.
The Co-Pilot on its own creates much better longevity inside of a properly functioning transmission, but may not be a 100% solution depending on the application. If internal transmission wear/damage, extreme towing weight, or significantly increased power are factors, then mechanical upgrades to the transmission's internals are needed in-conjunction with the Co-Pilot.

With easily selectable programs available in-cab to the driver and exclusive strategy for keeping the 68RFE Transmission alive, the Co-Pilot is a great solution for 6.7L Dodge Ram Owners who tow, snowplow, street-rod or compete with their truck.

A Billet Converter By Any Other Name Is Not The Same

We see a lot of 'billet' torque converters on the web and in ads these days and wonder how many people understand the inner workings of them enough to know the differences in brands and what offers the biggest advantages. So many of the converters available are simply a stock-style rebuild stuffed into a billet cover with few true modifications to make them better and stronger than stock.

While the billet cover is a feature that we build into the Five Star and TripleLok Torque Converters which prevents warping and 'mushrooming', that is just the beginning. The other main components of the converter's internals are just as critical to supporting increased power output from the engine and serious towing weight. These other areas include: lockup clutch system, lockup apply piston, turbine and impeller, stator, bearings, and hub. When ATS builds diesel torque converters all of these areas are given equal attention and all aspects are greatly enhanced.

Torque Converter Info

By looking at the internals of the Five Star or TripleLok Torque Converters compared to the stock unit (above) it is clear how much work is really done to provide increased strength. Most other upgrade converters simply change part 'A' (billet cover), but the rest of the internal structure is mostly just a stock rebuild. The ATS cover begins to show drastic differences from all others in the fact that the mounting surface features a twelve bolt design (with bolt holes incorporated into the cover) versus the factory six (with bolt holes welded on externally). Stock converters are completely missing section 'B' and have a single clutch friction surface bonded to part 'C' (piston). Our design is very different in that we add a multi-disc clutch pack (part 'B') which more than doubles the torque-holding ability by distributing load and using locking square tabs on each disc. The square tab design is patented and exclusive to ATS. The stock stamped steel piston 'C' is replaced with a billet dampened piston that doesn't warp and provides a cushioned engagement compared to other aftermarket designs which don't have a dampener. The turbine and impeller (parts 'D' and 'F') are furnace brazed and reinforced to prevent flattening or damaging of the fins due to fluid pressure wear. Finally a proprietary billet CNC machined stator ('E') is used to provide optimized fluid redirection between the turbine and impeller.

Conveying how different and how much stronger the ATS design really is versus stock and other aftermarket units is always a challenge, but those that have visited our manufacturing facility in Colorado instantly see quality and workmanship that set the Five Star and TripleLok Converters apart from all others.
