Wastegated Diesel Turbo System
MOST PEOPLE WHO purchase a diesel Pick-up Truck do so to take advantage of their reliability, economy and longevity. The only disadvantage is that, without a turbocharger, they are low on power, especially at high altitudes. Towing, climbing hills or even just trying to maintain highway speeds can be frustrating experience. Turbo charging solves this problem by increasing the amount of air delivered to the engine. By increasing the volume of air in the engine, sufficient oxygen is then present to complete the combustion process which increases horsepower and reduces smoke. Even with increased fuel delivery, sufficient air is available to complete combustion. there are in fact, many reasons to turbo charge your diesel.
MORE POWER increased towing ability, reduced exhaust emissions and instant throttle response are just a few of the benefits. Most importantly it improves drivability, making your truck more enjoyable to operate. No longer does towing need to be dreaded. Now, hills, long grades, and passing opportunities can be accomplished with ease.
WHY A BYPASS TURBO ? The bypass turbo has many distinct advantages over a non-bypass turbo, particularly in the light truck applications. By using a bypass (commonly called a "wastegate") turbo, turbo lag and exhaust smoke are virtually eliminated. In fact the ATS Turbocharging System exceeds current California Air Resource Board tough air quality standards. Engineered to match engine requirements, the bypass turbo offers fantastic throttle response throughout the entire engine rpm range. The bypass turbo creates manifold pressure just above idle for instant throttle response. The bypass valve then opens at a predetermined manifold pressure level letting the unneeded portion of the exhaust flow freely. This eliminates turbo lag without sacrificing mid and high engine rpm range performance.
IN THE ATS SYSTEM we use a large bypass valve that is engineered to accommodate the engine exhaust gas volume. By using a large bypass valve and a large final exhaust expansion chamber we maintain very low exhaust back pressure. This low back pressure results in increased combustion efficiency. Combined with a recommended fuel settings, up to a 50% increase in rear wheel horsepower can be achieved.
The ATS pressure chamber has definite design advantages. The volume being small enhances turbo response and helps alleviate turbo lag along with having excellent air distribution between cylinders. The pressure chamber uses an 0-ring seal between the machined turbo compressor discharge and pressure chamber and intake manifold. The 0-rings make a clean pressurized positive air tight seal.
Simplicity of the new ATS wastegated turbo is shown in the turbo mount casting which has two machined 0-ring grooves. This casting which functions as the oil drain for the turbo returns oil and utilizes an 0-ring as the seal arrangement. This casting also seals the hole in the rear of the intake manifold with an 0-ring where the anti-depression valve was previously located. This steel casting also functions as a fixture to mount the turbo to the engine.
The ATS air filter design utilizes a free flowing paper element with a pre-oiled foam panel for higher filtration efficiency and a longer life. The by-pass (wastegate) valve is opened by an actuator, which in turn allows exhaust gases to by-pass the turbine wheel. This results in a regulated boost level and reduced back pressure, increasing engine efficiency.
The ATS "Y" casting balances the engine's exhaust pressure through means of the close radius bend in the casting. This matches the close radius bend in the stock left bank exhaust manifold. Initially balanced exhaust pressure greatly enhances throttle response and adds to engine life. The ATS System uses a gradually tapered inlet casting which is void of any bends. This results in increased exhaust gas velocity and very low cylinder back pressure. It is, in fact, the lowest in the industry.
The turbo outlet housing with expansion chamber is very unique. This outlet housing allows for quicker wind up of the turbo and is a prime contributor to the efficiency of the ATS Wastegate Turbo System. Advanced Turbo Systems highly recommends our free flowing 3" mandrel bend exhaust system (mandatory in California) which is manufactured from aluminized steel tubing to eliminate corrosion. A turbo elbow housing and free flowing 3" exhaust system is also available to upgrade the Ford factory 2 1/2" system.
THE VEHICLE also remains emissions legal in all 50 states. Fuel delivery, which affects horsepower and smoke, are determined by a snap throttle opacity test making a pyrometer unnecessary. Simply stated exhaust opacity is the amount of visible exhaust smoke the vehicle emits. By setting fuel delivery in this manner, you are assured of excellent performance and a clean running vehicle. This is one time when clean air standards make the consumer the all round winner. Greatly improved performance, significantly lower emissions and smoke are all benefits you will enjoy with an ATS Turbocharging System
WHY AN ATS Turbocharging System? As the designing engineers with Navistar on the Ford factory turbo, we know turbochargers. Advanced Turbo Systems also believes in being totally honest with our customers. Questions about warranty, power gains, serviceability, or any other concerns you may have will be answered with Your best interest in mind.
YOUR ATS SYSTEM was designed to the highest engineering standards available with emphasis on quality and reliability. Thousands of hours of dynamometer testing by Navistar confirm these results. In addition no other kit will outperform an ATS Turbochaging System. The ATS System will produce as much if not more torque and horsepower per cubic millimeter of fuel delivered than any other system on the market. Dyno tests show that the system that comes closest to our new by-pass turbo is our discontinued non-by-pass version. And please don't be fooled by staged comparisons. More horsepower is always available by increasing fuel delivery, however, our recommended settings ensure engine reliability and durability.
SERVICE IS AVAILABLE at ATS Dealers across the U.S. and Canada. Also as a result of our association with Navistar and Ford, most Ford Dealers are familiar with the system. The ATS Wastegated Turbocharging System is emission legal in all 50 states. California E.O.# D-171-7.
ADVANCED TURBO SYSTEMS products have always been built to the highest level of engineering standards and there is no finer system on the market today. We challenge diesel owners to find a better system at any price!
EXCELLENT TURBO APPLICATION The Ford/Navistar 6.9/7.3 liter diesel engines are well suited for turbo charging. These engines have many features normally found only on industrial and heavy duty commercial diesels. These features include forged steel crankshaft and connecting rods with (4) bolt main bearing caps, gear driven drive train including a gear driven oil pump, valve rotators on all valves, exhaust valve inserts, oil cooled pistons and an integral tube type oil cooler. In addition the 7.3 has web bracing to strengthen the block, better air flow in the heads and the head bolts are increased from 7/16 " to 1/2". The angle in which the glow plugs enter the pre-combustion chamber has been changed to decrease the air disturbance which results in better cylinder combustion.
INSTALLATION ATS has always had systems that are easy to install. The new wastegate turbo is considered by many mechanics to be the best yet. With the 3 in 1 turbo mount the turbo placement is at the top rear of the engine, leaving the engine compartment uncluttered for normal service. The new wastegate turbo system is a true bolt on system that fits every 1983 through 1994 chassis model 6.9/7.3 diesel with any transmission option. The E40D transmission requires a FORD built transmission module. All necessary parts and a step-by-step instruction along with detailed drawings are included in each turbo package.
ENVIRONMENT In a time when pollution is out of control and smog fills the air, we at ATS are pleased to have a product that not only increases rear wheel horsepower up to 50% but also eliminates the majority of visible black smoke emitted from your diesel. This is the same black smoke that paints your boat, camper, or RV black when towing.
PROVEN PERFORMANCE With the up to 50% horsepower increase at the rear wheels and low end torque that is achieved through turbo charging the 6-9/7.3 L diesel, towing and mountain driving becomes a distinct pleasure. Advanced Turbo Systems was chosen over all other aftermarket companies to join forces with Navistar and Ford in designing the turbocharging system which is sold as a Ford Factory option. This association was a result of Navistar and Ford recognizing our ability to design a superior product. Final approval of the system came only after Navistar engineers had performed 20,000 hours of cycle testing, countless hours of shake tests, flow tests, durability studies, inspections and dyno testing to tough O.E.M. specifications. The results of the ATS design and Navistar's O.E. level testing and refinements is a system unmatched by any aftermarket product for reliability and performance. This joint venture was so successful that some competitors use it as their benchmark in misleading advertising.
SERVICEABILITY By removing the air filter assembly, one can remove the fuel injection pump, injectors and glow plugs without disturbing the turbo system. Also by removing the final exhaust pipe one can remove the transmission without disturbing the rest of the system. This is made possible because of the cast "Y" and turbine inlet casting. If service is necessary ATS dealers across the country can help you. If an ATS dealer is not convenient you can get qualified service at most Ford dealers because of the similarities in turbo packages. The heart of any system is naturally the turbo. Most turbo kits use various components from different turbochargers to match the engine as close as possible. As the ATS system was designed for an O.E.M. application, Borg-Warner, the acknowledged leader in turbocharger technology, designed and manufactured a turbocharger specifically for this engine. The Borg Warner turbocharger exactly matches the engine's intake and exhaust flow requirements for maximum performance. Additionally, as an O.E.M. component, parts availability and serviceability are unsurpassed.
