Guys the FRPP root-style S/C is not available for the 99-00 GTs yet. Currently Roxanne Shepard is running a prototype version that may hit the market by Spring of 01. The latest MM&FF has her car captioned on pg 132.
And the hp and trq gains will be impressive for the 99-00 GTs.
She ran a 12.54 in the Modular class at World Ford in St. Louis.
