Crucial for starting or expanding power gain modifications INDEPENDENT TESTING SOUL dyno tested a C8 ZR1 at Vollux Autowerks with SOUL 3.5″ Competition Exhaust System only and revealed max gains of over 125 whp and 168 ft-lbs of torque at 4,000 RPMs and peak gains of roughly 65 whp and 43 ft-lbs of torque on 93 octane gas (blue dyno graph lines). During a second round of dyno testing at KIES Motorsport with the full SOUL 3.5″ Competition Exhaust System we added Soler Performance Throttle Bodies and a JB4 piggyback tuning device (green dyno graph lines) which added further gains of over 110whp and 163 ft-lbs of torque for a total of over 173 whp and 209 ft-lbs of torque gained from stock ! Race gas would easily allow for power numbers over 1,200 whp.
