Hi Tommy! Depends on what you're trying to do. Taking off in a normal situation (street driving) is a devoped 'feel'. Slight increase in the gas combined with a slow engagement of the clutch to take off smoothly.
Now racing: that's a balancing point! (note: Sidestepping is just that-sliding your foot off the pedal to the side, letting it pop up). Also known as 'dumping' the clutch. How you launch depends on your car. If your RPM's are too high, you'll just sit & spin-not good for drag racing. If you dump too low, you'll bog out and maybe stall-looks dumb too!
Finding the sweet spot where you 'let fly' and get a little tire spin, then hookup, takes practice. Some guys slip the clutch a bit if their tires are too slippery, but that's pretty hard on the clutch.
My experience was pretty much (small block-4 speed car) dump at around 2200, then 'feather' the gas pedal until it hooked, then floor it!
