Installed my own Paxton......took 33 hours, but I have a bad back.....and I took my sweet time! Superchargers on line gave me a better price than Superchargers for less. $6,500 delivered to the door. When found out that a local tech wanted $2,500 to install......I took it upon myself to install. The crank damper bolt was a ***** to "break loose", and had to buy a 3/4 drive 350 lb capacity torque wrench from Harbor Freight to get the job done! (250 lbs from the factory!)......and drilling and pinning the crank damper was &%$(*&##!!! PITA!....other than that no issues except, it's a tedious job.....now that I know what to do with the experience that I had with this one, it would be much easier. The installation manual is really very good..had 2 questions during the install with wiring, and the help line had me on the right track in no time!! To say the least, I had a sense of accomplishment when I finished, and EVERYTHING worked! No issues to date, and runs like a scalded ape! (Also have Belanger,s and 3:55 gears, which I recommend with this kit!
