Big horsepower on pump gas with a modern EFI powerplant is becoming easier and easier to come by these days. Power-adders, such as superchargers, have elevated the horsepower potential for the average guy's engine combinations tremendously over the last decade, and it seems to be only getting better. One of the leaders in supercharger systems on late-model muscle cars is Kenne Bell in Rancho Cucamonga, California; and they were our choice for the blower on our Chevrolet Performance LS3 crate engine that we'll be dropping into a project car in 2014. With three different blowers available, including the 2.8L, the 3.6L, and the biggest of the group, the 4.2L, Kenne Bell can give their customers whatever power output they desire, many times without even opening up the engine. We opted for the middle child of the family, the 3.6L Mammoth supercharger. Using highly efficient screw-style rotors, an integrated intercooler, and a rear-feed 168mm inlet manifold, this supercharger can push your late-model powerplant to phenomenal power levels; some have made 1,000 hp to the wheels with this same supercharger.
Since there are a few different accessory pulley configurations for the LS3, we contacted Turn Key Engine Supply in Oceanside, California for the blower and bracket install. Turn Key has been involved in high-performance LS engines for decades and can handle everything from basic street powerplants to the most radical street/strip engine combos. Turn Key is also very familiar and has a lot of experience with our Kenne Bell blown LS3 combo; as a matter of fact, they just happen to offer a similar setup in their catalog. Because of this, we knew our bullet was in good hands.
Check it out as we show how Turn Key sets up Kenne Bell's systems on one of today's most potent V-8s. Shop operator Paul Headrick even drives a wicked twin-turbo LS-powered early Nova to work from time to time.
