I was sitting in class today obviously not paying attention when I got this idea.
When launching a stick. Why not keep the clutch as engaged as you can without dumping it, while holding your foot on the break, when the light goes green, just slip your foot from the brake to the gas. I know this would probably burn up the clutch really fast, but would it help speedwise?
Thats what a line lock is for. You set it and when the tree drops you dump the clutch and hit th eline lock switch and launch.
Semper Fi SAINT. May you rest in peace.
It does burn up the clutch really fast, that's why you shouldn't do it. What I do, is feather the clutch for the last couple feet to the stagings beams to feel out where the point of engagement is, the hold it just below that, so I don't heat up the clutch too much. When the lights go down, I floor the gas while letting up on the clutch quickly to the point of engagment, but without full pressure plate force. If I get equal amounts tire spin and clutch slippage, I know I did the best launch I could get out of the car. That rarely happens, mostly becasue I don't get enough track time, only like 8 passes per year. Still, I get 2.1's and 2.0's like that. Still waiting to hit a 1.9.
Don't use the footbrake, just use the ebrake... most people can barely manage to get a launch even close to right with their foot totally dedicated to the gas pedal, much less trying to work the brake and the gas... In reality this would be more useful for a turbo car since it would allow you to build boost right off the line.... even though power on launch is rarely the problem with racing FWD's, its putting that power to the ground. You have more than enough power to break the tires loose launching without the brakes or ebrake, using a technique like that would be something to use with slicks. And, as discussed, it will burn up your clutch very quickly. An inexperienced driver would probably toast the clutch before they even got the strategy down well enough to see any improvement in their times.

ive never even herd of using the e-brake
i do exactly what nitro does
I don't use it either.... however the guy who taught me how to launch uses this technique because he runs slicks. He also happens to be THE fastest stock turbo 1.8T with no nitrous, 12.4's at 107 mph.

You dont want to use the e-brake. When you put a load on the engine with the rear brakes engauged, it unloads the front suspension and youll lose traction.

it scalled "pre-loading" and it only works if you are good at it

Stop being such a good driver Jarrett! Hehe when I get my manual hopefully with the skills I pick up from you, Pj, Rich, Mandy, and Jay I will be as good as the rest of ya.
Hmm interesting
Well I guess i'm just plain boring here. All I have ever done was stage the car bring the rpm up to where the power band starts( 4k w/Grand Am 3k w/Trans Am) dump the clutch. If i start to get wheel spin I feather the clutch to keep rpms up in the power band.
This has worked well for me and I cut great lights with both cars, along with some of the best ET's with a stock Trans Am 12.84.
Most J's aint makin any power in the lower revs so loading up the clutch at low rpms wont help ya. That 4 poper needs to rev, the highr rpm ya leave the line at the better.
