I see, but i am not racing... or what the term "launching" refers to. I mean just to get the car moving, I say maybe under 5 mph?, parking lot speed. Am I suppose to release the clutch right after it hooks? but if i did that, the car will not be smooth. This is on first gear btw.
Eh, on this site, getting the car moving is called a launch. No matter if its slow city driving or racing. "No-gas launches" certainly aren't very fast but they're still called launches
Whenever I launch, I bring the clutch up to the friction point, and depending on how fast I need the launch to be I rev accordingly. Revving higher and slipping the clutch faster gives a very quick launch and that's what you want for racing. A slow launch means you need to rev low and slip the clutch slower, and that requires more feel for the car. Sometimes I won't give it any gas and slowly bring the clutch through the friction point/zone (its more of a zone than point because its an area of the clutch pedal's travel where the clutch is slipping/grabbing), that's called a no-gas launch. Normal launching though usually means bringing the clutch to the friction point, revving a little to 1200 or so RPM's, bringing the clutch through the friction point and then releasing it fully. That all happens much faster than it sounds, like you can bring the clutch to the FP and rev to 1200 at the same time, and then finish releasing the clutch.
