The National Association of Diesel Motorsports (NADM) is one of the hottest growing outlets for performance diesel owners to put their trucks to the test in drag racing, sled pulling and dyno shootouts. Serious diesel power requires a serious damper. Fluidampr remains the ‘Official Damper of NADM’. Diesel truck owners need not look any further than their big brother diesel engines in trucking for a testament to viscous damper protection. Some of those guys pound out 2000ft-lbs/650hp every day with the damper only replaced around every 500,000 miles!
Not all viscous dampers are created equal. For example, new 6.7L Dodge Cummins come stock with a viscous damper, BUT it is not a Fluidampr (Vibratech TVD) and not SFI 18.1 certified for competition. SFI 18.1 means the damper is constructed and independently tested to withstand 12,500rpm to 13,500rpm for 1 hour! Crazy rpms in the diesel world, but a testament to the quality an 18 to 29lb. Fluidampr Performance Diesel damper is built. In NADM, any competition truck turning over 4,500rpm is required to run a SFI 18.1 spec damper.
