As you can see in the dyno sheets included in this listing the test cams came in well above the stock run and even above a 1250cc equipped with HD Stage II cams.
Starting from the bottom:
Run #1 Test bike: 2012 VRSCDX 1250cc motor.
Mods: USED Gen 1 Ground Pounder exhaust, Daytona Twin Tec VRFID ECM. Nothing more nothing less. 124 HP / 88.1 TQ
Run #2 Test bike: 2010 VRSCDX 1250cc motor.
Mods: HD Stage II Camshafts, VH Comp Series exhaust, Daytona Twin Tec VRFID ECM. Nothing more nothing less. 134.2 HP / 90.4 TQ
Runs #3-5 Test bike: Same 2012 VRSCDX 1250cc motor from test #1.
Mods: FM HellRazor camshafts, Gen 1 Ground Pounder exhaust, Daytona Twin Tec VRFID ECM. Nothing more nothing less. Best run 140.8 HP / 94.9 TQ
That's a 13.5% INCREASE over stock and a 5% INCREASE over HD Stage II camshafts.
Also the minimal overlap did improve throttle response along w help capturing the intake charge during that period.
The cams are a billet forged steel not cast chinese junk! 100% AMERICAN from start to finish thru and thru!
