Hey Brother...Lighten Up!

The newly introduced Fowler F-11 Xtreme takes the best. . . and makes it even better!    When you need Xtreme performance and the flexibility to tune your blower to achieve the right level of boost for a given overdrive, the F-11 Xtreme is your answer. The top of the blower case includes a removable insert – what we call an ‘Air-Shoe’. By unbolting and swapping in a different Air-Shoe length, you change the flow characteristics of the incoming air and this influences how boost levels correlate to overdrive ratios. We have a variety of different Air-Shoe designs – we’ll be happy to customize your specific supercharger to meet your racing needs.

In addition, a variety of additional features takes the F-11 Xtreme beyond the standard F-11 and puts it squarely in the front of the supercharger pack:

• Swappable Air-Shoe inserts – customized to meet your needs

• Teflon stripped end-frames to achieve optimal boost levels

• CNC case relieving, profiling and pocket milling – reduces the overall

   weight by an incredible 9.5 lbs!

• Strategically placed rear fuel port – for additional case/rotor cooling
