2006 Ultimate Adventure - 2007 Toyota FJ Cruiser Buildup - Part 5
|
With a truck that will weigh more than 5,000 pounds and only a V-6 to push it around, we started looking for options to give the aluminum block 4.0 some help. Our previous experience with supercharged V-6s had us hunting for a blower, and only one version is available for this new Toyota engine. The team at Underdog Racing Development (URD) answered our call and brought their new Rotrex centrifugal supercharger kit with them. Similar to a turbocharger, the Rotrex centrifugal supercharger increases boost with rpm, but it is also extremely efficient, compact, and reliable with no internal belts or gears.
