Dyno Results
Here are the results! Chance's GT/CS produced a whopping 652 RWHP at 6400 RPM and 599 RWTQ at 4700 RPM. If we do the math with the 10R80 and the drivetrain loss factored in, this is right on par with Roush's production numbers for the Phase 2 kits. We hope this dyno gave you some more insight on just what this 2021 GT/CS with a warranty is capable of.
