This is how to Launch your car perfect using a Clutch Release Valve – Video
Consistently launching your vehicle perfectly every time can be a hard skill to master. The difficult part is that you can break a lot of pricey parts while you are learning the skill, so the learning process can get very pricey and financially not good .
Launching too aggressively can break components or spin the wheels, launching too soft will cost you the race.
Using a this hydraulic valve between the clutch pedal and the slave cylinder on the gearbox can control the speed that the clutch lets go, and do it at the same speed every single time, regardless of how your foot comes off the clutch pedal even if you side step it.
There is a mechanical model that slows the clutch pedal release in every gear shift, or an electronic model that can be set to only slow the clutch release on the take off, and then allow normal clutch operation in the following gear shifts on your pass.
Using a clutch release valve can take the inaccuracy out of your take off, which will give you more confidence to win most of your races.
