Found myself doing this by accident (if you see what I mean) in the Audi today. It is a more intuative method in the Audi with a slow responding engine.

I used to use it in my S2 - the bizarre hinged/sprung throttle pedal made 'proper' heel-and-toeing impossible.

Yes, the throttle in the S2 (all B3 Audi's infact) does not get the best reports...

The turbo charged engine is not the quickest to respond to a "blip" of the throttle anyway with its dual mass flywheel. It is VERY smooth though!

You cant go wrong with a little blip on down shifts to smooth it all out... Well, i suppose you could, but.......

It saves clutch wear a bit as well.

In theory, you are just doing the 'heel' of the 'heel and toe' technique.

Sounds good to if you have a decent engine!

I'd previously 'blipped' downchanges in my Celica and Volvo C70 to match the revs at clutch re-engagement, but found that the RV8 in my Chimaera doesn't hold the revs for long enough, so it was very difficult to time it spot-on. I now use more of a 'squeeze' than a 'dab' (following suggestions on a ride-drive day) - easing the revs up to the relevant revs for the gear/speed and then re-engaging the clutch. Easier to do, and works just as well in my other half's TD Astra too. Doesn't sound as 'cool' as a blip or a heel/toe, but is much easier to do every time and works for me!

If you already had 8000rpm on the clock, why would you be changing down?



Depends what car you've got I do it quite a lot in my RX8, which happily spins upto 9500 8K has only just opened the third air intake port on the engine, so there is plenty more revs to pile on.

I'll give this technique a try sometime.

So you're telling me that in an RX-8 you could be "pootling" along at 8000rpm and need to change down to get more power?

Although it will rev to 9500 rpm, I suspect peak power is a bit lower than that. Or are the gears so close you only drop a couple of hundred rpm on each change?
