Yes. Think you want to rev the engine and the transfer gears together. Otherwise, you may be wearing the clutch out.

collin, I agree on all accounts about it being tough to find the right gear. With my 5-speed 911 I find it much easier to find the right cog than with my 6-speed MINI.
Yea, can you imagine what it's like to drive an 18-speed semi with no synchros? Those guys do double/triple-clutching on any grade. Try missing a gear in an 18-speed box. Ouch!

Zamirz. What you were doing by not revving the engine with the clutch out basically you could achieve the same thing with the single clutch downshift

How about the tipsters?

Hey, how bout you tipsters? Do you blip the thottle when you downshift? I find it to be smoother if I do blip the gas a bit even when I downshift in a tip. I tried it in a loaner boxster. Not sure if it's a good thing for the tranny.

I use to double clutch my MGB all the time. It had a bad syncro, and that was the perfect way to drop it into second gear.

Cool. Those were the days. I used to do it in a Fiat 124 Sport, Triumph Spitfire and TR4

I do all kinds of stuff with my audi Tip. When I downshift i always blurp the throttle because I engine brake a lot. Also a trick I learned is if you accelerate then when you shift take depress the peddle a little bit then gun it and it will accelerate all the way through the shift seemlessly as if its all one gear. There are a few other things but i cant explain them.

this article is expalining it just like I did, only better. If you are using the outside of the top of your foot (where your toes are) to blip the throttle, there is no benefit of this vs using your heel instead. Either way is sufficient.

Exactly...being in tune with the revs and wheel speed (Matching them) in the various gears is the key and the hardest part. You really need to know your car...Still work in progress for me.

Like I said, if your comfortable with it that way and achieve the same ends...more power to you. Using the ball of the foot for both brake and blip is more common, imho...

LMAO at Matt. Instead of arguing with the article you argue with yourself. Nice.

A question for the masters of heel-toe and double-clutching...since I'm still an amateur. After blipping the throttle in either the heel-toe or double-clutch, does the accelerator need to be used in conjunction with letting out the clutch or is it simply blip up the throttle then foot off gas, drop clutch??

Also, the 5spd A4 that I drive, despite having a wonderfully smooth gearbox, might have a worn out clutch. 57k miles, and the clutch can be pressed about 2-3 inches for engaging, leaving more than a foot of pedal travel. Is this a clutch problem or something else?

the exact action and part of the foot will depend on the car. In the Porsche i use the right side of my foot to blip the accelerator because the pedal is hinged at the floor. In the Elise i use my heel because the pedal is hinged from above. I much prefer pedals hinged from above instead of the floor hinged Porsche pedals.

When you rev match correctly you should be able to let the clutch out rapidly and have it be totally smooth. It should feel just like it feels when you let the clutch out and the car is in neutral.

Pedal travel has nothing to do with clutch wear. When the clutch wears out you will notice it slipping. The revs will jump up without the car accelerating.
