More than just a blower, the Vortech supercharger system employed on the crate motor came with all the mounting hardware to complete the installation. Note the use of a V-belt drive system for the alternator and water pump, while the blower relied on an 8-rib serpentine setup.More than just a blower, the Vortech supercharger system employed on the crate motor came The carbureted blower assembly also featured a 180 degree (composite) inlet and free-flowing air filter assembly. This should allow users to position the filter away from heat sources or (preferably) serve as the beginnings of a complete cold air system.The carbureted blower assembly also featured a 180 degree (composite) inlet and free-flowi The carb linkage (shown here during mock-up with a Holley carb) was actuated via a splined (and sealed) shaft run through the carb enclosure.The carb linkage (shown here during mock-up with a Holley carb) was actuated via a splined Boost supplied by the Vortech supercharger is controlled by altering the size of the blower (or crank) pulley. A larger blower (driven) pulley will reduce boost pressure, while a smaller one will add boost. The opposite is true of the crank (or drive) pulley.Boost supplied by the Vortech supercharger is controlled by altering the size of the blowe Blower belt tension was controlled by an adjustable idler pulley. Though not spring-loaded, this system has proven effective on literally thousands of supercharged applications.Blower belt tension was controlled by an adjustable idler pulley. Though not spring-loaded After producing 264 hp in normally aspirated trim, the Jegs crate motor pumped out 383 hp and 431 lb-ft of torque with the Vortech supercharger.After producing 264 hp in normally aspirated trim, the Jegs crate motor pumped out 383 hp Naturally Aspirated 260hp 350:As is evident from the graph, the Jegs/GM crate motor was designed more with economy in mind than maximum power. Rated at 260 flywheel horsepower, adding a small Quick Fuel carb, Edelbrock Performer intake and HEI distributor allowed the 350 small-block to produce peak numbers of 264 hp and 353 lb-ft of torque. The low-budget normally aspirated crate motor was equipped with a 4-bolt main block, LT1 PM rods and cast pistons (all new parts, by the way, not remanufactured). Jegs/Vortech Supercharged 350:As expected, adding the Vortech supercharger dramatically improved the power output. The peak numbers jumped from 264 hp and 353 lb-ft of torque to 383 hp and 431 lb-ft of torque at just over 7 psi of boost. The efficient Vortech supercharger improved the power production of the crate motor by an impressive 45 percent. Even more important is the fact that this supercharged 350 comes complete and ready to run.
