Speed of Air Engine Technologies Breakthrough Piston Technology

Speed of Air® (SoA) Engine Technologies has developed patented technology to enhance the efficiency of medium-duty Cummins®, Powerstroke® and Duramax® engines, providing measurable performance and fiscal benefits. SoA’s patented piston treatment on its Hyperformance Pistons™ provides increased torque, horsepower, reduced emissions and greatly improved fuel efficiency. These improvements also contribute significantly to extending engine life and reducing service intervals. The fuel savings alone, documented by independent commercial users, are as much as 25 percent and more, a critical aspect for fleets facing higher fuel prices.

The SoA patented technology primarily consists of precise, CNC-machined indentations on the piston top, called turbulators, but most often described simply as “dimples.” This precisely designed and manufactured technology is executed to exacting tolerances under ISO 9001 quality standards. These turbulators create a thinner, well-attached boundary layer between the air-fuel mixture, its flame front and the combustion chamber walls. This thin, turbulent layer allows the combustion flame front to burn much closer to the cool metal walls of the combustion chamber, thereby increasing overall combustion efficiency. The result is significant reductions in fuel consumption, reduced emissions, increased torque and horsepower, improved drivability and pulling power. Lower soot emissions translates to better engine longevity and fewer service intervals.

SOA’s Hyperformance pistons also includes the application of aerospace-proven thermal barrier and anti-friction coatings on the piston crowns and skirts, respectively. The thermal barrier coating retains heat in the combustion process, thus providing additional efficiency and power. The anti-friction coating minimizes abrasion and resistance for even more efficiency. The combined technologies of a Speed of Air Hyperformance piston provide documented and significant benefits with a distinct value proposition.

Lab tests as well as years of real-world operational field testing in a wide variety of applications confirm the results. Notably, DFC Diesel, an innovative industry leader and Canada’s largest diesel engine remanufacturer, has been independently testing SoA technology for nearly two years in more than a dozen Dodge, Ford and Chevy trucks. DFC’s testing has been so successful that this company is now offering an entire line of Speed of Air® remanufactured engines.

During testing, DFC Diesel observed fuel consumption reductions of 25% or more with factory tuning, an average of 5% increases in torque and horsepower, NOx reductions as high as 80%, and the ability to extend oil change intervals by 50% due to decreased soot and fuel dilution. Observed benefits also include reduced regeneration cycles, DEF consumption, and visible exhaust/opacity, along with noticeably smoother and quieter operation.

To manufacture these custom piston kits, SoA has licensed United Engine and Machine Co. (UEM), a leading manufacturer of pistons with over 100 years of experience and a well-earned reputation for quality. As a family-owned and operated company, UEM has in-house design, development and manufacturing capabilities that allow this firm to meet nearly every type of engine’s piston needs.

The supercharger utilizes the largest, most-efficient rotating group produced by Eaton, the TVS2650.

Harrop has released its innovative TVS2650 Supercharger Kit for the Ford 7.3L Godzilla engine. The supercharger utilizes the largest, most-efficient rotating group produced by Eaton, the TVS2650 and has an inverted design increasing the plenum volume to maximize performance. 

The front drive / front inlet design allows for a shorter less restrictive intake path allowing for improved airflow and superior performance. Like all Harrop products, the TVS2650 for the Ford 7.3 Godzilla is expertly assembled by qualified supercharger technicians to ISO9001 quality standards, before being individually tested in-house on a dynamometer to ensure reliability and durability.

Carrillo Forged Pistons and Connecting Rods for Ford 7.3L Godzilla

These pistons are forged from 2618T aluminum alloy and machined on dedicated CNC machine cells to tight tolerances. 2618 aluminum has a lower silicon content than other alloys. That makes the pistons stronger and more ductile—perfect for high-load, high-stress applications like superchargers, turbochargers, or nitrous oxide.  Related Articles – Fluidampr Harmonic Damper from Summit Racing

Fluidampr Harmonic Damper from Summit Racing Equipment

The factory harmonic damper on your modern GM, Ford, or Mopar V8 are ‘tuned’ to absorb what’s called torsional vibration in the engine’s normal operating RPM range. Performance modifications, particularly ones that increase torque, produce added vibration in an RPM range that the elastomer damper wasn’t designed to handle. That vibration will accelerate component wear,
