B&M Launch Control

[Mick]

Hey i dont know if anyone has seen these before but this unit can lock your front brakes without locking the back ones, but i beleive this can somehow make launching quicker for drags .. probably not much but may squeze a split second or 2 ..

It would save your back brake pads while doin lines, but we all have skylines here so doing burnouts isnt realy a problem. I just mentioned this item for something to talk about..

That's not a launch control, it's line locker.

Just stops hydraulic pressure getting to your read brakes when you want to spin em up.

Illegal for the street.

yep, its called a launch control unit though.

Pretty sure they are two completely different things mate. How having only the front brakes engaged helps launch is beyond me as one foot is on the clutch and the other on the loud pedal.

Launch control units cut fuel and/or spark to let you choose a desired launch rpm and be able to hold the throttle down flat with the revs not climbing above the set level.

Launch control and a line-locker are two totally seperate devices AFAIK.

I know little about launch control although was under the assumption it interacts with your transmission and is possibly some form of stall-converter on auto or limits wheelspin (feel free to correct).

Line-locker on the other hand is as old as the hills and performs as follows: 1) driver presses brake pedal which in turn sends fluid to both front AND rear brakes thus engaging the caliper, 2) driver presses line-locker button (generally located on steering wheel on drag cars) and then releases brake pedal, 3) brake fluid remains LOCKED in front brakes thus keeping front calipers locked but rears unlocked, 4) driver warms tyres and engine via means of burnout as front tyres are locked (only useful in RWD obviously).

Watch Jap drag footage such as GT-R class and everybody rips the line-locker and bags the tyres prior to racing.
