Bolting on a supercharger can be either an adventure of a lifetime or a long series of nightmares. We've seen both. Whichever card fortune deals you, the result is the same: big power and the ultimate speed part singing a tune only the experienced ear can recognize. This yarn is about the V-1 centrifugal supercharger from Vortech and how much fun it was to install one on our 305-powered 1991 Camaro.
The V-1 is the Vortech supercharger for domestic machines that will see street duty. The base model is the S-Trim that produces around 6 psi right out of the box (depending on engine displacement). The beauty of the V-1 is its versatility and upgrade capability. In the past, the next step up was the R-Trim, a fairly heavy-duty piece that was more race than street. Now the T-Trim is available, filling the gap between the S and the R. We didn't even try to talk Vortech into sending a T-Trim for the Camaro because it is simply too much for a stock 305. Instead we used the V-1S-Trim; it is a real-world, anyone-can-do-it, bolt-on kit. It comes with everything but tools, and the instructions are simple to read. There were a couple of minor surprises and the standard bonehead maneuvers on our part, but otherwise the project went well with minimum chopping.
