1967 Chevy Camaro - Spin Cycles

As we've noted elsewhere, there's really no substitute for an air/fuel meter when tuning a carbureted supercharged setup. "We used to read the plugs, and then add timing until it rattled," reminisces Endress. Point taken, but it's hard to beat being able to see the air/fuel curve. The top curve is with the 3.12-inch pulley and unchanged jetting. It runs into the high 11s, which is too lean for this type of application. The lower curve shows the much richer mixture achieved with a jet change.

The supercharger system in Shane Ganzel's '67 Camaro is based on what Vortech calls its tuner package. This setup comes with everything included you needed to install the system, except for a carb enclosure and discharged tube. The heart of both systems is Vortech's V-2 SQ S-Trim compressor. It flows up 1,000 cfm, supports up to 680 hp, and features computer-designed helical gears to cut down on supercharger whine.
