from what I can make out from here, the only difference I can see which matching revs as opposed to I normally change down is a quick tap on the loud pedal just after you depress the clutch but before you change the gear?

or am I missing something?

edit: the next article is about heel and toeing, what difference is there to the first page except for you're braking whilst blipping the go pedal?

I thought the first example was for shifting down when approaching a corner but then that's what heel/toe is for, no?

*confused*

 

Heel toeing is rev matching, its the same thing.You only do it when changing down gear while braking.

 

I see ..silly confusing site!

 

and double de-clutching? LOL

 

Rev matching in itself is a way of being more mechanically sympathetic. It works best if you separate the "speed change (braking) from the gear change" phase of slowing down for a hazard.

So, Brakes until you're at your new desired speed, off brakes. Then clutch out, revs to bring the engine up to the correct speed for the road speed and your new gear, then into new gear and clutch back in. If you get it right it should be nice and smooth. If you can do it perfectly, it's actually possible (but not sensible) to pull the stick out of gear, and then match the engine and gearbox speed perfectly for the "new" gear and so make clutchless gearchanges. Try this on a car you don't like very much.

"Heel and Toeing" is the term given to overlapping the braking and rev-matching parts of this process, such that you stay on the brakes at the end of the braking phase and either use the side of your foot or rotate your ankle so that you use the heel of your foot to press the accelerator to bring the revs up.

Really, IMO, heel and toeing isn't appropriate on the road. It's about shaving split seconds off of lap times and possibly retaining the balance of the car when braking, turning and changing gear all at the same time. If you're doing all that on the road, likelyhood is your're trying too hard/driving too fast for the conditions. IMO. (Prepared to be flamed for that because obviously we're all driving gods, but it's true. Half the people who SAY they always heel and toe won't have a clue).

Rev matching is however a vital part of driving smoothly and quickly. Likelyhood is you do it to some extent without even knowing it. Most people with an ounce of mechanical sympathy do.

 

Well i do it almost every time i shift down during normal city driving,just for a practice that is.

I did notice it goes better when driving hard

 

I heel and toe when in attack mode but other than that I like the pops and bangs I get on over run

 

the reason i ask is that i'm usually at the wrong revs for the gear when shifting down, so get a "lovely" judder when shifting down.. annoying, that!

 

Heel and toe is as much a part of how I drive as pressing the clutch to change gear is, it's totally automatic for me. I just feel it is a lot more mechanically sympathetic and gives a much smoother ride for me and my passengers. Also you save brake pads from extra engine braking!

 

It takes time to learn to get it right and even then you'll not do it bang on everytime.

I started doing it in my first Impreza and have continued to do so up to now. I've got a mapped A4 diesel now and still do it. I like to think it will extend to life of the dreaded DMF.

 

I always either rev match or heel and toe, you dont have to be braking hard atall to lean your foot over and blip the throttle coming upto a junction etc.

After a while it just becomes second nature and part of how you drive.

 

I agree that heel and toeing is pretty much unneccesary for the road, but rev matching is a good habit to get into, I learnt from bikes, which tend ti get more upset if you bung the wrong gear in at speed. (ie locking the rear wheel up)
It also enabled me to drive my car 3 miles home when the clutch went, teaches mechanical sympathy!

 

Get EcuTek racerom it will do it for you...

 

You don't have to be a hoon to heel'n'toe, sounds mint if you get it right, but like LewisL, sometimes I don't because of the pops and bangs!
