***Your car will still retain the factory belt, but “Modifications” to the blower are required! The nose-drive of the supercharger will have to be machined down to clear this small pulley. It is possible to do this machine work by “hand” with a Dremel or similar tool. Keep in mind that the supercharger can be damaged!
*Boost levels are subject to ambient air temperature, weather conditions and elevation.
**No ECU Tuning is required for this Supercharger Upgrade!
