[05/24/2001] RAM VDS Diaphragm Clutch System Released


VDS (Variable Diaphragm System) is a clutch system, just released by RAM Clutches, for racers either requiring or desiring to use a diaphragm clutch system. The clutch features variable static pressure settings. This is a complete assembly including flywheel, pressure plate, and disc.

In drag racing, the clutch is the traction control device for the car. The clutch system applies stored energy to the rear wheels during launch. To obtain optimum clutch performance, you must have enough flywheel mass to get the car moving and enough clutch clamping pressure to accelerate the vehicle. RAM claims the VDS allows you to set up the clutch to optimize your engine / vehicle combination for superior performance.

However, RAM also says the VDS system is set up with the maximum clamp pressure from the factory. They recommend beginning with a high clamp load, as insufficient clamp pressure will cause premature wear to the clutch disc. After a few baseline runs, the clamp load can be varied to further optimize performance. The pressure ring is user-replaceable in the field.

The RAM VDS clutch system is SFI approved for competition, which is required in vehicles running 11.99 or faster in the quarter mile.
