After their inaugural appearance at Summernats 25, Australia’s premium dyno manufacturers, Mainline DynoLog Dynamometers, are once again supplying dynos to the Summernats 26 Horsepower Heroes competition.

Mainline will be supplying and operating, two XPC2200 model chassis dynamometers. These twin retarder dynos were designed and purpose built specifically for Horsepower Heroes. They feature multiple traction enhancing devices not normally available on their mainstream models. 

The key component of this unique model is the traction module (aka “whale tail”) attached to the rear of the dyno, and the integral cable and pulley assembly on the underside of the chassis bed. This is all activated by a powerful pneumatic ram that results in a down force being applied to the vehicle. This ensures maximum traction and consistent results on the rollers during all power runs. 

After the exceptional performance of this model dyno at Summernats 25, many of the traction enhancing concepts have now been implemented and available on other models. 

Check out all the action in the Dyno Cell during Summernats 26 and discover who will be crowned “Horsepower Hero” for Summernats 26.
