If you have been following along with our ProCharged pony project car, you know we are making about 330 hp and 389 lb-ft of torque at the rear wheels. This equated to a best elapsed time of 12.87 at 112 mph. Our GT sped through the traps singing at 5,900 rpm in third gear thanks to the 2.73 rear-axle ratio.
We felt this was a pretty good elapsed time, considering it was 28 degrees outside and we were rolling on Nitto NT550 street tires. Careful application of the throttle was needed, otherwise we just went up in smoke. Our next track test featured far better traction, which revealed that the stock replacement clutch was slipping when shifting into high gear, so we are taking measures to remedy this problem.
The first of these measures is the installation of an adjustable clutch cable and aluminum quadrant. While there are quite a few of these on the market already, the Pro 5.0 unit is the latest incarnation of this simple, but effective device. While it really can't fix an ailing clutch, proper adjustment of the cable is essential to longer clutch life.
The Pro 5.0 piece uses a standard replacement cable in conjunction with an aluminum adjuster that mounts on the firewall in an easy-to-reach location. An aluminum quadrant is included and replaces the stock plastic pieces.
For this installation, you'll need 7-, 8- and 15mm sockets, and either a set of ramps or a jack and some jack stands. Some quadrants require the use of a spacer to keep them from moving around on the shaft. Rather than use metal washers (and spend money for them), we ingeniously cut part of the old quadrant to fill in the gap.
Other than that, the installation is a snap. For proper adjustment, the pedal should have little to no play in it, and you should be able to flex the cable down at the clutch fork about 1/2 inch. Once your adjustment is set, lock down the adjuster and you're done.
