This new Vortech blow-through supercharging system (see page 54 for our test) for carbureted small-block applications is a bolt-on package that increases horsepower up to 75 percent. The kit provides a straightforward integration with factory-serpentine or V-belt accessory-drive configurations and fits nicely under the most stock hoods. Options include the Vortech V-1 T-Trim, V-2 SQ S-Trim, or the super high-output V-7 YSi-Trim compressor. The carburetor enclosure allows the use of Holley, Mighty Demon, or Quick Fuel carburetion. All belts, pulleys, and brackets are included.
