Alpha Powersport's Turbo Kit puts out 254 WHP and 272 WTQ on only 6psi, that's 17 more HP than any other competitor's turbo kit and with one less pound of boost. Not only did we make great power but our kit was tuned and with drive-ability dialed in. If you look at the dyno chart you can see how smooth the power band is, factoring in 13% power loss in the drive train and calculate crank HP, we are still at 287 hp on only 6psi! As most of you know the Slingshot doesn't need a huge bump at low end, a huge bump at low end would just result in tire spin. Dialed on the dyno, the power band is very smooth with no huge jumps.The Alpha Turbo Kit Includes:Turbo:We use turbos from Precision Turbo & Engine, one of the leading turbo manufacturers who are regularly breaking records with their ever evolving line of turbos. Their line of Billet and CEA turbos revolutionized the turbo industry and many top horsepower cars and race teams are using Precision turbos. Check out our dyno video! Our kit uses a journal bearing billet 5558 with CEA technology wheels, we chose the 5558 to maximize the most power at the lowest boost possible. This allows us to create a smooth responsive power band.Turbo manifold:Initially we thought about building a custom tubular manifold but after inspecting the factory manifold, we found that it actually flows very well. Using the factory manifold is also a way to keep the price low and not skimping on quality while still yielding good results. To utilize the factory manifold, we machined a adapter plate so the turbo bolts to the factory manifold (realistically with bigger injectors, pump and tune this kit could make 400+hp). We plan to have tubular manifolds as an option in our future kits. ECU /Tuning: Custom reflash of OEM ECU Wastegate:Our turbo kit has an external gate and a CNC ported exhaust housing to ensure reliability and stable boost. The wastegate is also from Precision, their 39mm wastegate pairs perfectly to their turbo.
