Tornado731s

Tornado731s refers to a series of high-performance, custom-built racing vehicles developed primarily for the *Track Day Racing* and *Time Attack* scenes, particularly in the United States. The name originates from the model’s association with the year 2007 (731) and the iconic *Tornado* nameplate, a nod to the legendary *Tornado* sports cars of the 1960s and 1970s, such as those produced by *Tornado Racing* and *Tornado Sports Cars*.

These vehicles are typically based on modified *Dodge Charger* or *Chrysler 300* platforms, though other chassis have been experimented with. The builds emphasize extreme power, aerodynamics, and track-focused modifications. Common features include high-revving *LS* or *Hemi* engines, often with forced induction (supercharging or turbocharging), custom drivetrains, and aggressive aerodynamic packages like large rear wings and diffusers. Suspension setups are heavily adjusted for track performance, often incorporating coilovers, sway bars, and track-specific tires.

Tornado731s gained popularity through online communities, particularly on forums like *TrackDayRacing.com* and *HotRod.com*, where enthusiasts shared builds, modifications, and track results. The name became synonymous with a specific aesthetic and performance philosophy, blending classic muscle car heritage with modern high-performance engineering. While not an official manufacturer, the "Tornado731" moniker has been adopted by individual builders and shops to market their custom track-focused vehicles.

The vehicles are primarily used in *Time Attack* events, where drivers aim to achieve the fastest lap times on designated tracks. Their design prioritizes straight-line speed and cornering ability, often sacrificing comfort and road-legality for extreme performance. As with many custom racing builds, Tornado731s are typically not street-legal in their final forms, requiring modifications to meet homologation standards for track use.
