TRACE OE600

A Powerful 600 Horsepower V-8 for OEMs and Retrofitters

The TRACE OE600 is a cost-effective, next-generation alternative to turbine powerplants. OEMs and STC retrofitters that upgrade from turbines to TRACE V-8s can save up to $200,000 per engine and take advantage of better takeoff, climbing and at-altitude performance.

In addition to flying further and climbing faster, OE600-equipped aircraft provide up to 40% savings in fuel costs and 50% savings in maintenance. OE600 maintenance intervals are based on hours only, not hours and cycles like turbine engines. The result is a substantial cost savings for short flight patterns such as those used by agricultural pilots and island hoppers.

World's Most Powerful Reciprocating Aviation Engine

TRACE engines outperform comparable turbines (450 to 750 horsepower range) in takeoff, climbing and at-altitude engine performance. The turbocharged OE600 V-8 engine produces 600 horsepower at takeoff and 500 horsepower continuously up to 20,000 feet (28,000 feet total service ceiling).

Comparable turbines suffer from a dissipated power band at higher altitudes due to the nature of their technology. For comparison purposes, it would require a 1000 horsepower turbine engine at sea level to match OE600’s performance at 20,000 ft.

Fuel Savings

The TRACE engine has a distinct fuel consumption advantage over turbines, especially for short flights and island hopping. Internal combustion engines such as TRACE are not hindered by inefficient turbine cycles. As a result, TRACE engines are 30 to 40% more fuel efficient than comparable turbines.

On a twin engine aircraft such as the King Air, turbines consume approximately 92 gallons per hour versus 52 gallons using TRACE engines. TRACE’s 40 gallon-an-hour savings, at $4.00 a gallon, equals $160 in savings every hour of operation.

Maintenance Savings

Turbine engine maintenance intervals are based on both hours and cycles - these can quickly add up over the life of an engine. TRACE engines are powered by internal combustion, meaning they will never require cycle-driven maintenance. TRACE’s lower maintenance requirements provide up to 50% annual cost-savings over the life of the engine.

For example, a typical turbine requires cycle service between 2000 and 6000 cycles or 2000 and 3000 hours, whichever comes first. TRACE engines do not require cycle maintenance and will ONLY undergo service after 1500 hours of flight time.
