Does anybody 'blip' the throttle on a down shift ?
I know is meant to give a smoother change, but one thing that i am curious about is does it give your clutch an easier life.
Any thoughts......

 

hmm i do it the odd time, not sure if it really matters either way though man, sounds good though.ha

 

Yes when double declutching.
Then sometimes just when changing down without double declutching.
Then I sometimes heel and toe as well.
Depends on the situation.
Clutch life? Not sure.
Matching engine revs to road speed on downchanges could, presumably, ease the load on the syncros.

 

99% of the time I blip, results in a smoother Journey for everyone and everything concerned at the very least.

I also heel and toe where possible. Keeps the car stable under braking, and again it's a smooth ride.

I've been doing it for a few years now and it's second nature to me now really.

 

Heel and toe is the name of the game, keeps things real smooth and is not just for racing drivers you know.

 

Always blip on every downchange, heel & toe where necessary. If you drive in the police class one pursuit style then heel & toe becomes less used as the brake usage is almost negated on all but very tight twisty roads.

 

I agree. I tend to just match the revs to road speed on downchanges when re-engaging the clutch. Under braking, I heel and toe if I need to change down.

 

Pretty much all the time. Blipping going down, and matching revs going up.
Double-declutch when cold too. Box seems much more happy - no reluctance in any gearshifts.


Learnt all the above because I once regulary drove early Porsche 911s. Driving them any otherway was pure ignorant abuse on behalf of the driver.

Oh and not to mention the early MTX75 equipped XR3 that spat out syncros on a regular basis


Right...who's going to start a thread asking who can do seamless clutchless gearchanges????

 

I always blip the throttle when downshifting - get quite a bit of clutch judder as my flywheel needs skimming, but doesnt do it when i give the throttle a little blip!

 

please explain i just match engine revs where possible. what's all this blipping & heel & toeing?

 

Blipping the throttle - when down shifting just hit the throttle to get the appropriate correct revs. Heel and toe is doing the same thing, but whilst braking. Using the outside of the foot to "blip" the throttle whilst you brake and downshift.

 

'Heel and toe' means braking with you right toes, whilst shifting your right heel across to 'blip the throttle as you change down.

 

Take care when learning to heel and toe. On a quiet road to start or preferably track.
Oh and if you want to double declutch on way up, no blipping just "engage" neutral as you change gear. I've sometimes used it on cars with "baulky" changes.
My old GTE 16v comes to mind.

 

Depending on engine revs and road speed i blip the throttle on downchaging.

One question...what exactly is double declutching and when do you use it?

 

"The purpose of the double clutch is to match the speed of the rotating parts of the gearbox for the gear you wish to select to the speed of the input shaft being driven by the engine. Once the speeds are matched, the gear will engage smoothly. If the speeds are not matched, the gears will "crash" or grate as they come into mesh. A modern synchromesh gearbox accomplishes this automatically, negating the need."

 

Good advice, or you might find that you get your wires crossed and just inadvertantly accelerate into the car in front!!

On the back of this.......


Had my scoob for about 6 weeks (been in the garage for 3)
Do you find since bying a faster car you end up breaking even more??

 

Nah, all that's bo**ocks, you blip the throttle to keep the Turbo spinning !!

Why not just turn the idle up to 3000 revs

 

Used to, not so much since learning class one pursuit techniques

 

Psst

Rob

 

Funnily enough I'm the other way around - brake harder in less powerful cars to try and make the most of the limited performance.

No class one pursuit training for me, just roadcraft course

 

only when im feeling in the mood, sometime double declutch when the gearbox is cold, like going into first from second, or second from third
