Air Intakes, Exhausts Boost Diesel Engine Efficiency

Air Intakes Exhausts Boost Diesel Engine Efficiency ENGINES You can boost the performance and efficiency of diesel engines with aftermarket products that modify air intakes and exhausts Several products are available for diesel pickup engines and brand name farm equipment Pusher Intakes is an internet only company that offers a modified air intake package for the 12 and 24-valve Cummins diesels used by Dodge Rams and the Powerstroke diesels used in Super Duty Ford pickups Pusher says that its Cross Air intake system will increase air flow boost turbo speed lower EGT’s and produce better fuel economy The Cross Air system has 3 1/2-in intake tubing that’s nearly the same size as the perimeter of the square shaped inlet of the factory Cummins intake plate This tubing provides the maximum laminar airflow to the engine without machining off the side of the head Pusher says the 16 gauge tubing increases the intake volume by 27 4 percent over the OEM intake The Cross Air intake system includes the manifold feeder tube boots clamps and hardware Prices range from $159 to $399 depending on engine size Installation is done by tapping into a freeze plug port at the rear of the intake plenum The Cross Air splits off the boost tube and creates another parallel path of air flow in addition to the stock plumbing The Cross Air is made from mandrel bent steel tubing and uses top quality 4-ply silicone couplers stainless clamps and 1 1/2 by 095-in DOM pipe Pusher intakes can be customized as needed and come ported for all boost input/output applications The kit is available in several colors Prices range from $199 to $699 depending on the engine application Contact: FARM SHOW Followup Pusher Intakes www pusherintakes com Parley’s Diesel Performance has air and exhaust tuning systems electronic performance chips exhaust upgrades fuel injection kits and other engine performance parts for diesel truck and farm equipment engines The company says anyone who owns diesel-powered equipment can increase its efficiency and power output by installing a performance air intake system The intakes work because they allow the engine to intake a larger amount of air through higher volume intake tubing When the engine gets more air flow the fuel burns more efficiently and produces more horsepower Parley’s high flow performance filters are washable and reusable Some of the company’s performance diesel intake systems are designed with heat shields or are fully enclosed to keep hot air out of the intake stream They also take advantage of technology like mandrel-bent intake tubes powder coating and high-quality hardware designed to reduce air restrictions and intake temperatures Cold air intake systems even take inlet air from outside of the engine compartment where the inlet air is cooler Cooler inlet air temperature translates to more power during the combustion process because cool air is more dense than warm air Parleys says a standard factory exhaust system can also rob a diesel engine of power and economy They use the analogy of blowing through a tube the size of a Bic pen filler compared to blowing the same amount of air through a soda straw With a restricted exhaust the engine is always “forcing” the exhaust gases out wasting fuel in the process Parleys suggests installing a larger diameter exhaust system with a smooth mandrel bent radius That could improve fuel mileage slightly and provide additional power from the engine The company goes on to say “even if your diesel is equipped with a catalytic converter or a particulate filter adding a larger diameter exhaust after the emission control device will still help improve your diesel fuel economy ” Prices for various kits range from $199 to about $1 200 Contact: FARM SHOW Followup Parley’s Diesel Performance St George Utah 84790 ph 801 938-4891; www parleysdieselperformance com
