And no, this article is not about shoes. It is not about double what else did your grandfather beat up classic cars with unsynchronized transmissions.
For the connoisseur is the walkover and the lad will firmly have heard of: downshift blip with and "heel-and-toe". The video Ayrton Senna in a Honda NSX Type-R at Suzuka is actually the standard for everyone who wants to know how to heel-and-toe looks like it is done perfectly, the images you check HERE.
Soon to much needed theory. Blip given during downshifts and particularly in rear actuators are quite hunted in speed is almost a must, if the car in question has a good ol 'manual transmission. Here's why.
There are three different areas of interest in these issues and they all run. This relates to the motor, the axis that enters the gearbox and the axis that goes out of the gear box and transmits the torque direction differential and the driven wheels; that is, the output shaft.
To illustrate, we outline the following scenario. You drive your balls at Zandvoort in the pants and bend X wants you downshift from fourth to third gear. At the time when the clutch is depressed, the transmission (i.e., input and output shaft) is disconnected from the motor. The speed of the motor will decrease with respect to the rotational speed of the transmission, because the latter is further from the rotating wheels, "driven", and will not give gas. The motor will thus solely be kept running by the flywheel, but the engine speed decreases. Now comes the important point!
You kick the clutch, the engine speed decreases, you switch back and let the clutch come up again. What this is due or may be, is that the engine suddenly have to turn more revolutions because the drive is suddenly back from the wheels. Engine and transmission are indeed back with each other and then also in another ratio, because you downshift a gear. The engine is running in third gear after all, more than speed in fourth gear, if you drive a certain speed.
The rotational speed of the engine thus rises suddenly because the transmission by engaging the clutch suddenly again is in connection with the flywheel. The moment at which this occurs is usually accompanied by a small electric shock from the coupler. You had probably by the same clutch that has suffered most from this difference in speed, and that's also one of the reasons why it might be useful to give intermediate gas. The other reason is the "jolt" that you feel let in to get the clutch. In a front-wheel driver not a disaster because you shoot what most straight, but rear actuators can "freeze" briefly and go in the round. No bueno!
The observant reader already had by that during braking, and downshifting occurs a difference in speed between transmission and motor. let in to get the link should the difference be raised suddenly and you feel a jolt or a rear breaking out, if you're unlucky. How can it be solved? Simple, whipped blip!
Exactly when the driver presses the clutch (and while inserting a lower gear) kick you briefly press the accelerator pedal to allow the engine speed to rise and the jolt is gone. It's as easy as that. Because you obviously do not want to stop brakes while giving blip, you two momentary pedal to pedal at a time. These are the brake (which you had been depressed) and the accelerator, which gives you tuft tussengas.
The best known and anyway most masculine way to accomplish this is called very far and technology. Here you brake with the toes of your right foot. By the foot to rotate a piece, it is possible with your heel to blippen the accelerator. This may seem in the beginning a bit tricky, but here too, practice makes perfect. Moreover, it gives quite a bit of satisfaction when you have the technique after some practice to master.
The pedals of the McLaren F1
Unfortunately, not every car is possible to apply this technique and that has to do with the position of the pedals. When standing pedals are the best in any case, but not every car. Moreover, sometimes the pedals are too close together to make the rotation with your foot. In that case you just brake with your right foot and give the outside of the foot (ie where your little toe is) a little gas during downshifts. Problem solved.
For those who were wondering: the street has little use for each roundabout blippen the throttle during downshifts, but with a rear actuator which receives considerable upside miserably, it is almost a must. Moreover, more and more cars robotized manual gearboxes that provide automatic blip for smooth gear changes. The gearbox is not forgotten, so it was in our opinion not hurt to still pay attention to this matter.
