STILLEN Dyno | The Numbers

From the factory the Hyundai Elantra N is rated at 276 flywheel horsepower. On our dyno we saw a maximum wheel horsepower output of 234 horsepower at 5700 RPM*. This is about a 15% drivetrain loss. After installing our TruControl by STILLEN Inline Power Module the dyno reported back a maximum horsepower output of 279 horsepower at 6,100 RPM*. Making the wheel horsepower greater than the factory flywheel horsepower with an overall gain of more than 55 flywheel horsepower* which equates to a total engine output of 335 flywheel horsepower*.  

Even greater gains come from the torque output. Maximum torque from the factory was measured at 243 torque at 2650 RPM*. With the TruControl by STILLEN Inline Power Module installed, our test Elantra N put down 294 ft. lbs of torque at 3200 RPM*. This is an increase of more than 50 ft. lbs of torque at the wheels*.
