Self Contained Small Engine Dynamometer
The SED-DY1 dyno is a simple to operate dynamometer (dyno) designed to measure power and test karting, mini bike, and other small racing engines. Power is measured by a load cell that is attached to a hydraulic pump, which acts as an engine brake. This dyno should not be confused with traditional Hydraulic Dynos that only measure hydraulic pressure. The NR-DY dyno is considerably more accurate and not affected by temperature change of the hydraulic fluid. While the NR-DY functions like a water brake dyno, it is portable and does not require any external water connections. Compared to an inertia dyno, the NR-DY is far more accurate and functional, allowing carb tuning, acceleration, and deceleration test, steady power readings, and engine brake-in. Compared to an eddy current dyno, the NR-DY dyno is a quarter of the price and just as accurate!

The SED-DY1 dyno is manually operated. While simple, it does require some operator skill to get consistent results. While a computer or automatic operation would be possible, this would add considerable cost and would not allow the flexibility of a manual dyno (carb tuning, power circuit tuning, etc.).

Available to test small block with 3/4" shaft (GX200 style and 6.5 clones), big block with 1" shaft (GX390, Predator 420, etc.), quarter midget engines (6 to 1 gear box, 3/4"), and GX270s with 2 to 1 gear boxes.

Maximum "real" HP is 35.

Basic Package includes:

Does not include fuel tank or motor mounts, unless ordered additionally. Dyno is designed to use PMR motor mounts. Dynos are built to order and take 4 to 6 weeks to ship. See specials for in-stock dynos. For questions regarding dyno systems, please email [email protected] or call 833-400-1969. Engine and/or exhaust system is not included.
