Back in the 60's and early 70's, car makers responded to the increasing desire for high performance vehicles by making a segment which became known as muscle cars. The original concept was to integrate the lightest platform with the largest engine, thus giving the buyer the best horsepower to weight proportion possible.
While many of the packages strongly publicized the car's capabilities (SuperBee, Boss 302, GTO, Challenger,etc.) some of the most powerful combinations had little to no options and no external differences from the basic car models to create a "sleeper."
The Thunder Pak concept starts with the lightest possible Tundra in the Tundra Grade Regular Cab, coupled with the overwhelming power of the 5.7-liter iForce V8.
The Thunder Pak system is intended to give buyers performance packages at a reduction to upgrade the performance of their Tundra. This modest truck has been outfitted with a tribute of TRD equipment including a supercharger which enhances the performance to 500HP/550TQ.
Performance has been further improved with a Nitrous Oxide Systems dual tank nitrous oxide system producing a dyno-proved 625 hp. All features of the engine are monitored through an assortment of Autometer Gauges.
