Jasper Engines & Transmissions has installed a computerized dynamometer to help in the development of new products and for use with the Jasper Authentic Custom Drivetrain division.
The Land and Sea DYNOmite, 2000 horsepower, water brake dynamometer provides exceptionally accurate horsepower and torque readings. It gives Jasper the ability to customize testing situations, and allows JASPER’s Product Development group to conduct long-term engine testing.
“We will use this dyno for 50-hour engine durability testing on all new products, before they are released,” said Brad Boeglin, Jasper product development group leader. “With the use of a MoTec Stand Alone Engine Management and Data Acquisition system for engine control, we’ll put an engine we are developing under various RPM, and load conditions to simulate real-world driving and wear situations. The full 50 hours are logged to verify VVT operation, oil pressure/temperature, water flow/temperature, exhaust temperatures, individual cylinder knock identification, oil consumption and engine timing change due to wearing timing components. This will give Jasper further insight into long term failures, and how to correct them, before a product is released.”
The dyno also allows Product Development and Quality teams to test engine parts, tolerances, oil pressure, sensors/solenoids, water flow/temperature differentials and much more away from production areas, and learn how those changes will affect an engine. “Engine parts stress differently under load conditions,” said Boeglin. “Using this specialized tooling, we can now put these engines under loads, test, and create tighter tolerances which, in return, will increase the life of the engine.”
Jasper Authentic Custom Drivetrains will use the new dynamometer to test their customers’ engines as an added service to the custom remanufacturing package.
“For an additional charge, customers can have their engine dynamometer tested. A printout of torque and horsepower readings will be sent with the engine,” said Boeglin. “Customers like that service as it allows complete testing of the engine with the customer’s fuel and ignition systems. Not only does it provide a higher quality product, it will take less time for installation into the vehicle.”
