Are Twin CP3 Fuel Pumps Harder On My Diesel Engine Than A Single?

"Are Twin CP3 Fuel Pumps Harder On My Diesel Engine Than A Single?" 

This question comes up quite a bit these days with the number of light duty diesel truck owners who are modifying their truck for more power and therefore needing to increase fuel supply. There seems to be much incorrect info to be found online and lots of hearsay dealing with misconceptions. The simple answer is NO.

What is true is that introducing a much higher-than-OEM amount of fuel pressure on a truck would cause issues over time with the fuel system and injectors. Before the release of the Twin CP3 Fuel System (sometimes referred to as a 'dual fueler'), there were many attempts in the industry to simply modify a single CP3 Pump for more pressure (as had been done in earlier 12 Valve and 2nd Generation 24 Valve Cummins pumps) in order to keep up with the fuel level demanded by power modifications. Some of these modified single pumps produce an unsafe amount of fuel pressure and lead to shortened pump life and driveability issues.

ATS Diesel released the Twin CP3 Fuel System which allows the addition of a second main injection pump or 'twin pump' to work in unison with the original factory CP3 Pump. The system uses a few key elements which make it safe and reliable for increased power. The Twin CP3 Controller (supplied with kit) is a self-contained micro computer which acts as an intermediary between the truck's OEM computer and the fuel system. The twin pumps are run together as if there were only one pump in place. An important factor is that fuel supply (volume) is maintained without using the high pressure found in other single pump upgrades. Because the two pumps run in unison, and are regulated by the Twin CP3 Controller, they perform their job at partial duty cycle and provide the required volume of fuel to the injection system. Since the pumps are not working as hard to maintain fuel supply, the life of each pump is extended beyond what a single pump would attain. This volume (as with turbochargers), is the important ingredient, as opposed to simply upping pressure. When a truck is modified for more power with tuning or injectors this fuel supply volume becomes a limiting factor for performance.

Because of the supporting installation hardware required and second pump, the Twin CP3 Fuel Systems are somewhat more costly than a single pump upgrade, but the performance and durability difference is drastic. Driveability is much better with the Twin CP3 Fuel System due to the fact that low-end and mid-range output pressures are consistent with factory levels and follow a smooth ramp-up. If performance, reliability, and quality are all important factors to a truck's owner - the Twin CP3 Fuel System is an easy and sensible choice when upgrading performance. Whether upgrading for towing and work performance, or building a hot rod truck, the Twin CP3 Fuel System is the ideal fuel supply modification.

Support Transparency in Public Land Designations

As you may recall, ARRA recently asked you to send a letter to your Representative about a leaked Department of Interior (DOI) memo that made it clear that President Obama was considering restricting access to public lands by declaring as many as 13 million acres in western states as National Monuments.  Thank you for responding. Your voice was heard and this issue has been addressed repeatedly in Congressional hearings, on national news and in many other ways.  But there is more to do.

House Committee on Natural Resources Ranking Member, Doc Hastings (R-WA) and Subcommittee on National Parks, Forests, and Public Lands Ranking Member Rob Bishop (R-UT) introduced a Resolution of Inquiry (H. Res. 1254) aimed at requiring the Secretary of Interior to turn over to the House of Representatives specific information related to potential National Monument designations and other public lands initiatives on April 15.  A resolution of inquiry is a method used by the House to obtain information from an executive branch official.  The House Committee will vote on the resolution on April 28th.

Sweeping National Monument designations like those outlined in the leaked DOI memo represent a serious threat to recreation including motorized access.  Any OHV use would almost certainly be forever banned in areas designated as National Monuments, and riders would have no opportunity to formally weigh in on the process.  Any decision that could potentially lock OHV use out of huge swaths of public lands should be made in the light of day, and that is why it is important for you to weigh in to support transparency.

Turbocharged Weekend In The Rockies - 2010 Diesels On The Mountain

2010’s Diesels On The Mountain At Bandimere Speedway

ATS Diesel will host the 2010 installment of Diesels On The Mountain at Bandimere Speedway’s Thunder Mountain located in Morrison, Colorado, as well as an ATS open house in Arvada, Colorado. Diesels On The Mountain and Truck Fest take place August 6-8. Competitors from across the US and Canada will converge in Colorado to battle for top honors in sled pulling, drag racing and the show-n-shine categories (many using one truck for all events). Cash, trophies and prizes will be awarded to top finishers.

Friday August 6th ATS will host an open house and Armed Services Appreciation BBQ for Colorado area military members at our Arvada facility. Activities at ATS will begin around 10:00 a.m. Various areas of ATS’ manufacturing plant and grounds will be open for tours for those interested in how our diesel upgrades are manufactured.

Saturday August 7th features the sled pull/ truck pull at Bandimere Speedway’s unique mountain-side venue. Action will take place in Bandimere’s outlying dirt lot with gates opening at 11:00 a.m. and pulls beginning at 1:00 p.m. All competitors and spectators are invited. Classes will range from stock trucks to heavily-modified dedicated pullers. 2010’s sled pull will be cosponsored and sanctioned by NSPA (National Sled Pullers Association) and will feature NSPA’s pulling sled which is one of the newest and latest technology sleds in the country.

Sunday August 8th Truck Fest transfers the excitement to the upper paved drag strip portion of Bandimere Speedway - sponsored by Cummins Rocky Mountain. Events for Sunday include drag racing, vendor midway, rock crawling, and show-n-shine competition starting at 8:00 a.m. Spectators will see some of the most unique and detailed vehicles in the truck genre. Many of the country’s fastest trucks will be in attendance to lay down impressive quarter mile times. As with Saturday, Sunday’s competition and spectator opportunities are open to everyone. Drag racing trucks are required to either have upward-firing exhaust stacks, or use a temporary exhaust turn-up pipe for this year’s racing. This change was made at the request of the track which must manage issues presented by smoke from trucks that can damage track property and disqualify racers due to issues with the timing light system. Clamp-on exhaust turn-up kits can be acquired by calling ATS directly.

Sounding A Sour Note - Utah's Congressional Bill To Ban Aftermarket Exhaust

Senator Patricia Jones from the Utah State Legislature recently introduced a bill (S.B. 106) this year which would effectively ban all aftermarket exhaust in the state. She must have missed her calling as a congressional rep in California..
The billed called for all vehicles to be equipped with an exhaust system that is “installed by the original manufacturer of the vehicle and is not modified; or meets specifications equivalent to the muffler installed by the original manufacturer of the vehicle and is not modified.” Each time that members of congress attempt to enact such laws one has to wonder if they realize the damage that they are doing to the economy and our freedoms. Whatever the initial intention was of this bill, it would be a lethal blow to many aftermarket companies who produce upgraded vehicle exhaust systems. Such laws can be compared to the ridiculous recent ban of all youth ATVs and motorcycles due to lead-based paint which has damaged the income and livelihood of countless companies.
OEM manufacturers are constrained to producing vehicle components cheaply in order to compete for price points in the market. This causes them to use lesser materials for things like exhaust systems. In contrast to aftermarket exhaust systems which are often produced out of stainless steel, the OEM system will typically be aluminized material. This leads to materials deteriorating over time and the advent of rusted pipes and mufflers which do not work as efficiently as intended (or as effectively as the aftermarket solutions). Whatever the initial intention is of bills like this one, the end result is lower quality products for consumers and less competition to drive innovation.
As is typical with bills such as S.B. 106 much of the enforcement by law officials would be left to subjective judgment as to whether the exhaust was in violation.
Luckily, for anyone who values freedom, within the past couple of days S.B. 106 was terminated for the remainder of the 2010 legislative year. Perhaps this was due to an overwhelming landslide of complaints from constituents who heard the news about the plan. Whatever the cause for the 2010 cap of the bill, aftermarket enthusiasts can almost certainly count on it rearing it's head once again in the near future. Emailing and calling congress members will continue to be critical in ensuring that more power-grabs like this don't become law.

Sawdust And Loud Noises - ATS Diesel Remodels

Customer service can be difficult with the droning buzz of a jackhammer mere feet from your desk. The customer service crew at ATS Diesel has found creative ways to be 'flexible' and persevere through the daily construction that has been part of a massive building overhaul at their Arvada Colorado HQ. Since neither the construction nor the day-to-day operations at ATS can be put on hold, much of it has occurred during the same hours.

Somewhere around six months ago the ATS building began undergoing the second major remodel in its six year history (the first being the initial move-in during the 2004-2005 transition). When the 104,000 square foot building was first purchased it was just an empty shell and it was difficult to know exactly what layout would be most effective. Over the years a number of ideas and plans were discussed to help streamline the production of a product line that now covers some six hundred products.

With many of the truck owners who upgrade their diesel wishing to have installation happen at ATS, the Arvada building tends to become a temporary home during the day to those that travel to Colorado from other areas of the country. For that reason the showroom and lobby areas have been a big focus and include some new amenities including a projection screen entertainment center lounge and video game room.

Manufacturing is being streamlined and departments such as engineering are shifting to different areas of the building to update procedures and increase efficiency. The ability to have a clean engineering area with updated technology will mean that products continue to be the best quality and fit for installation on trucks. Consolidating production areas like converter machining and laser cutting are already helping to make a difference in production turnaround times. Things have come a long way from the previous ATS facility and even the current building in its original form.

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.
