High Performance Cycles
Test Completed April 2011
Jeff Jerome, owner of High Performance Cycles, conducted the recent independent dynamometer testing at his shop, located at 426 E. Duval Street, Lake City, Florida 32055.
Jeff, a graduate of MMI-Orlando and Advanced Dyno Operations, has over 20 years experience in the motorcycle repair and performance industry. His business, established in 1997, is a full service shop that provides Dyno Tuning, Engine Building, Repair, Parts and Accessories for American and Metric motorcycles. Jeff stated “I was pretty surprised with the test results. I didn’t expect Dynacycle Oil to perform so much better than Syn3.”
Using a 2010 Harley-Davidson Ultra Classic as a mule, testing was conducted on a Dynojet 200i dynamometer. Other than changing the oil and oil filter, no further changes were made to the motorcycle before or during each phase of testing. Both tests were conducted at an engine temperature of 190 degrees.
With an outside room temperature of 73.7, the dynamometer measured 59.0 horsepower during the Sreamin’ Eagle Syn3 testing phase. During the Dynacycle Oil testing phase, the dynamometer measured 61.2 horsepower even though the outside room temperature had increased to 75.5 degrees. That’s an increase of 2.2 more horsepower by simply changing the oil from Screamin’ Eagle Syn3 to Dynacycle.
