As if the massive swept volume and superchargers weren’t enough, the top of the manifold is also the base for eight nitrous-oxide bottles. An engine of this size does not rev very high, as you may expect. The builder of this custom truck is Mike Harrah.
The 13-ton truck has a chromed Allison HT740 transmission. Peterbilt air leaf suspension supports a custom chassis and steering system. The rig rides on Alcoa aluminium wheels wrapped in 315/30R/22,5 tyres.The truck also features a customized independent suspension, a manual gearbox, and power disc brakes.

The stretched Peterbilt chassis measures a whopping 44 feet long and weighs 32,000 pounds, but Worldwide claims a top speed of 130 mph when the nitrous boost system is activated. In addition to the engine’s 12 superchargers, there are also four 12-foot drag parachutes to help slow down THOR after Vmax runs.
