I ran a Tilton carbon clutch capable of holding 2000 HP on another car. While it had very light peddle pressure, engagement was like an on off switch. Would not recommend for street use.
Keep in mind these are made of resin for the most part and require an adapter to fit. They do look good, but having a hard time with the idea of replacing the original properly threaded aluminum ball with plastic.
Once you factor in the cost of all the equipment required to make this work, may as well just get a standby generator which will have much more power output and longer run time.
With the help of some stickers, my emblem has now reached just about full and even corrosion coverage. I kind of like it better than the original brushed look.
