THE PERFORMANCE CENTER
Let's talk torque, horsepower, speed – and gas mileage! Southern Thunder Harley-Davidson offers full service engine building and dyno tuning. Our experienced techs are prepared to build any level of engine, big or small. Whether you are looking for a little more pulling power, or on a weekend quarter-mile bike, we’ve got you covered.
DYNO SERVICES WE OFFER
Standard Horsepower and Torque Runs: We do about 5 pulls with your bike on our dyno to measure the max horsepower and torque.
Carburetor Tuning: This involves tuning your carborator by replacing jets if necessary and measuring horsepower / torque.
Harley-Davidson® Pro Super Tuner with Custom MAP: For Harley riders, pairing Screaming Eagle Super Tuner with the dynamometer is the ultimate for performance tuning. The Super Tuner allows us to modify the air-fuel ratio by modifying injector operation, spark timing, and valve opening for each cylinder. It Involves installing the Super Tuner, a fuel delivery modification device. on your bike along with creating a custom MAP. It includes runs for horsepower and torque measurements.
Fuel Economy Optimization - The dynamometer is a good tool for optimizing fuel economy using air-fuel data and diagnosing drive train issues by using a negative horsepower test, which measures rolling resistance caused by mechanical components.
Dyno Troubleshooting - When it comes to everyday motorcycle performance measurement, problem diagnosis and precision tuning, the Dynojet 250ix Inertia Dynamometer offers fast, accurate and repeatable solutions. Our technicians save time by simply running your motorcycle on the dyno and analyzing the data. Troubleshooting ignition vs. air-fuel problems, or rich vs. lean conditions, becomes more visible and allows us to dial your motorcycle in to almost 100%. In addition, it also allows us to diagnose mechanical issues that may not be noticeable without tearing into a powertrain component.
OUR DYNOMOMETER
Southern Thunder Harley-Davidson’s Performance Center offers the only Dynojet 250 I in the MidSouth – It is the “gold” standard for performance measurement and engine tuning – capable of accurately measuring up to 500 bhp and 450 ft. lbs. torque. With it’s built in air/fuel ratio analyzer, and integrated eddy current brake damper, this is the most up to date dyno ANYWHERE! It allows our service technicians to help you get the most out of your Harley-Davidson® upgrades and diagnose those pesky issues that can only be detected under load. Our Dyno is also equipped to handle Trikes and Four-Wheelers!
Dynojet 250i
The Dynojet 250i Load Control Dynamometer is the choice of Harley-Davidson Factory Trained Technicans. The 250ix Inertia Dynojet Dynamometer provides Southern Thunder Harley-Davidson Technicians with instrumentation and facts instead of seat-of-the-pants guesswork that you may get elsewhere. The 250IX uses Wide Band Technology, which provides you with an exact Air Fuel Ratio of both cylinders. Other dealers without a Dynamometer use Narrow Band Technology which basically provides an indication of rich or lean and are essentially on or off, leaving very little adjustment.
Map Fuel Injection
Fuel Injection Tuning is easier than ever with the Dynojet 250i. Offering the latest in eddy current power absorption technology, the Dynojet Load Control System is easy to operate and offers steady-state load control. Closed-loop load control software provides the technician with the ability to control RPM or MPH at any throttle opening. This causes the motorcycle to automatically hold at the technician's pre-determined setting. Repeatable, consistent results are very easy to obtain. And the Air/Fuel Ratio Monitor shows the exact air/fuel ratio across your RPM range.
The 250i Load Control Dynamometer is perfect for duplicating specific customer complaint conditions, engine break-in, durability testing and fuel injection mapping.
INC Dyno Room
The INC rooms are designed with features specifically intended to work with Dynojet Motorcycle and ATV dynamometers. Designed and constructed of 4" thick modular acoustical metal panels and components, the INC Dyno Room allows safe operation of the dynamometer while providing excellent exhaust ventilation and high performance sound reduction of 40 dBA or more.
