Right or Left?

[fletch101101]

Unless you have an old rally ledgend with a 2million BHP Turbo with major lag where you need to keep the tubo spinning there is no point in left foot breaking it jsut ****s the car up...... although a do rev match and clutchless shift when slowing down

Have tried left foot braking and it just didn't feel right plus i was over braking.
Think most of us that have driven manuals then go to automatic will naturally right foot brake as it is habit!!

 

[raphjd]

right foot, of course

Right, of course.

i dont understand how you do a rev match. how do you know what rev you can change down at? is the same revs on every car?

Practice. It doesn't sound pretty the first few times, clutchless upshifts are 'easier.'

The revs will change from car to car, even in the same car, you need to be mindful of roadspeed. The process for going down would go something like: Pull out of gear, blip throttle, and at the right moment, push it into the next gear. Upshifting is easier, you lift off, and pull it through to the next one when the revs are just right. Get it wrong, and you need to blip the throttle while the box is in neutral and have another go. Or just slam it home, depends on your attitude...

Isn't the V8 supercar acceleration... plant right foot. While keeping right foot planted - kick clutch as you pull for the next gear. Don't move right foot. Repeat until terminal velocity.

Nah, they have a little trick, thats rather pretty neat. Mounted in the gearshift knob is a little rocker switch, so when you pull the knob, it moves a little, activating the switch, which is connected to.....the ignition. Cuts spark for the briefest of moments, and takes all the load off the drivetrain. They do tech explainations on the Teev during broadcasts, I'll go hunt for one now.

Revs matching is easy. Upshift quick enough for the revs to drop the right amount. Not so fast you have to ram it in and not so slow the gearbox has to pull the engine back to speed.

To down-shift slightly missmatch the clutch & gas pedals so the revs blip & immediately push it down a cog. You will often down-shift quicker than you can up-shift. You cant do it slowly as the revs will have dropped off.

I'm from a biking background so I always match the revs, its better for the gearbox and makes for a smoother less lurchy drive.

Bikes have constant mesh (like cars) but don't have synchro cones on the drive dogs. You use the clutch to pull away and then upshift with no clutch. Gently preload the gearlever then momentarily dip the thottle to unload the gears and the next one slots in. Downshifts its the missmatched revs and clutch technique. Try to use the clutch on upshifts and its really hard to get a good clean shift.

Competition race & rally cars use the same type of gearbox as bikes - sequential shift without synchromesh.

Left foot braking? Completely pointless on the road even with an auto box.

I use right foot braking, as most people that aren't race drivers do.

I have been trying to perfect rev matching lately, seem to be doing a good job of it. I heard that it also helps the ABS on a car when heavy braking to do rev matching also, Can anyone clear this up for me?

thanks, il give it a practice
bludvl.. you said it doesnt sound pretty when you get it wrong, does it do any damage to the gear box?
