From the Driver SeatAfter filling the fuel tank with the now-required 91-octane gasoline and running the truck through some dyno testing, we opted to evaluate it with a less-scientific-but certainly still relevant-metric. Was the burnout smoky? Check. Was it loud? Check. Satisfying? Check. And, did it leave a measurable amount of tire rubber? Check. Oh, and we also got a boost of 6 psi, 404.76 hp at 5,250 rpm, and 463.97 lb-ft at 3,850 rpm. The stock numbers were 220.03 hp at 5,100 rpm and 250.35 lb-ft at 4,000 rpm. Installing a supercharger takes time, money, and skill. Do you have all three? Then put a supercharger on your truck right now! And, be sure to take it to a pro to get the job done right. The installation for a supercharger is relatively straightforward, but it is labor intensive, and the stakes are extremely high if you do it wrong.
