What started out as practice for track use has turned into a (possibly bad) habit, so I thought I'd pose the question as to whether blipping the throttle during "normal" driving conditions can harm my car? When I say normal, I mean almost every change down...

Presumably it'll be consuming a little more fuel, but are there any other factors that I need to take into account?

If anything it will be beneficial.

So long as you are accurately matching engine revs to road speed you are actually reducing wear on your car.

If you are giving it too much throttle and the car pulls forward as the clutch comes up that's not so good....so practice to make sure that doesn't happen.

Heel and Toe is not a bad thing.

i thought this was a good thing due to equalising the speed differential thorugh the clutch?

not that i do it myself mind.

The whole purpose of it is to eliminate the snatch from the drivetrain which could upset the balance of the car on the track. Doing it on the road won't be quite as critical as unbalancing the car, but it can help extend the life of the clutch and gearbox. Also, it's quite fun and makes you look like a rockstar biggrin

When I used to drive a manual box, I always used "Double de clutch", with a blip as you release the clutch for the first time.

Then again, I have never taken a test in a car, I was taught in a 3 tonner, and you had to "Double de clutch" then, so the practice stuck with me.

No worries now though, been auto for 10 years.

Ahhh, 4 positive replies in as many minutes! Good good!

That may explain why my clutch has lasted as long as it has - over a year ago I noticed that it was slipping badly if I planted my right foot when in 6th gear. 12 months on and it still slips when in the higher gears, but no problems (knocks wood) for the lower gears.

I know, i know, just replace the d*mn clutch!

Crash box. Old school!
Indeed, but old habit's stay with you sometimes. Twas in 1970 when I did my course, I think the Bedford RL's were syncro box's, but 1st to 2nd in the military landrovers weren't

I have been doing it for every since I learned to drive. The beuaty of having your uncle teach you who was also a driver in Formula 3000.
