Theory of Operation - What is a CDV?
The Clutch Delay Valve (CDV) is a one-way restrictor installed by the factory between the clutch slave cylinder and clutch master cylinder, as shown in Figure 1. It "delays" the engagement of the clutch, much like old record players used a damped tone-arm to gently lower the needle onto the surface of a record.
Because of this valve, no matter how quickly you lift your foot off the clutch pedal, the clutch engages the flywheel at a constant (slow) rate. In theory, it can save the driveline from shock, were an inexperienced (or immature) driver to dump the clutch at high RPM. But in practice, all it does is prematurely wear out the clutch and turn experienced drivers into people who, despite 20 years of practice, cannot shift gears smoothly. During parallel parking maneuvers, the delay can be infuriating, causing constant clutch slippage. And during hard acceleration, the large amount of clutch slippage can greatly shorten the life of your clutch. During normal, sedate driving, the shift from first into second gear is often jerky, leading passengers to question your skill. As the driver, you can see your passengers' heads bobbing back and forth during every shift! Yes, in their minds, they are laughing at you.

Benefits of replacing your CDV with a modified unit
Shifts are quicker, more precise, and the response is instant. Launching is easier, because instead of the car slipping the clutch for you, now you can do it properly. No more vague, inconsistent clutch engagement. No more jerky 1-2 shifts. You can actually chirp the tires when shifting from 1st to 2nd gear! Parallel parking becomes a breeze and your clutch will love you for it and last much longer. Best of all, your passengers will stop making fun of your driving skills.
