Here is #RallyFist, the RallyWays Ford Fiesta ST on the dyno at HG Motorsports to log the power gains of the Fiesta ST COBB Stage 3 package.
The dyno is DynoDynamics (which is accurate but reads really low) and the numbers are converted to DynoJet. The baseline numbers were done on the same dyno, same location, so they are accurate.
Watch the video to see all the details and see the power gains as a result of going full COBB stage 3.
The dyno run was performed by Mike Petruzzo at HG Motorsports in San Diego.
