The Dynocom 5000 Series chassis dyno is getting significant performance and convenience upgrades.

The Texas-based company announced at the SEMA Show that the 5000 Series will have a high-flow fan to cool the Frenelsa eddy brake and an LED light to illuminate the vehicle’s undercarriage. To support higher loads and speeds, Dynocom is upgrading to a patent-pending taper shaft  that mates the rollers with the brake.

“The shaft starts at 3-inch diameter,” explains Allison Blackstein, director of sales and marketing at Dynocom. “There’s an 8-degree taper down to a 1 7/16-inch shaft. The design adds balance and strength to the construction.”

The redesigned tapered shaft is stronger and improves roller balance. Note the knurled rollers for increased traction.

The 5000 series is popular with auto shops, based on its quality parts content, versatility with all types of FWD/RWD vehicles and $16,995 starting price. The dyno supports speeds up to 175 mph and 5,000 lb-ft torque. Maximum axle weight is 6,500 pounds, and track width stretches from 36 to 86 inches.

Dynocom has added an LED light to illuminate the undercarriage.

One of the leading features of the 5000 series is the machine-cut knurls on the drive and ilder rollers. Other chassis dynos may only have the drive rollers knurled which, according to Dynocom, could lead to high-horsepower vehicles trying to climb out of the bed and up on the roller. Dynocom says knurling both rollers leads to more consistent  and repeatable testing.

The 5000 series is plug-and-test, as long as there’s a 220-volt power supply. Options include aluminum ramps, air brake and lift-assist kit, above ground kit and a caster/dolly kit for portability around the shop.

“The 5000 Series can be upgraded to all-wheel-drive in either fixed or adjustable wheelbases,” adds Blackstein.

Dynocom also introduced an entry-level Dyno X model at SEMA. This chassis dyno has a starting price of $10,995 and can be used as either front- or rear-wheel-drive applications. It’s usable up to 800 horsepower, including 600 steady state, and a max speed of 155 mph. An all-wheel-drive version is available for $24,995.
