Cobalt SS Supercharger Upgrades and Tuning

This week we were able to upgrade two Chevrolet Cobalt SS’s, one silver and one red. Both received similar modifications, though the Dyno Dynamics results varied based on supporting modifications on the LSJ engines.

Silver Cobalt SS: Full exhaust, 2.85 pulley, 60# injectors, tuned on HP Tuners by Hal at Dynosty

Red Cobalt SS: Stock with GM Stage 2 pulley upgrade and injectors and HP Tuners dyno tune. 211whp
