The Camaro 2010 ProCharger HO system can safely add more than 175 horsepower when installed onto the stock 2010 Camaro SS engine while still running pump gas and enjoying all the day-to-day driveability you’ll want to experience every day. Thanks to ProCharger's industry-leading technology, ProCharger produces more power with less boost than the competition. Owners can expect 500 rwhp on otherwise stock L99 Camaros and 525 rwhp on otherwise stock LS3 Camaros. Higher boost and power levels are available for modified engines.
