Types of shifting
First, let’s talk about three different types of shifting and show the progression from slow and easy to fast and, umm, nope- we won’t go there.
Granny Shifting
When we first learn about the mysteries of the manual transmission and that third little pedal on the left we all heard something like this- “Ok-wiggle the stick and make sure it is in neutral, gently push in the clutch all the way, carefully push the stick into first gear and slowly release the clutch and give it a little gas.� This would result in one of two outcomes- a hard lurch and stall or almost no perceptible forward motion and the sweet odor of burning clutch accompanied by shouts of “Let it out! Let it out!� Once the car actually moved in first you would repeat the process for each successive gear shifting as high as 3000 rpm and letting off the gas between shifts. With practice you could do this smoothly and even quickly, conjuring visions of Dan Gurney blasting down the Mulsanne straight.
Today, we politely call this process Granny shifting- guaranteed to prolong the life of both transmission and clutch and not raise any eyebrows with your local patrol officers.
Speed Shifting
If you are reading this then you assuredly moved on to the next stage, which we call Speed Shifting. Once you had a taste of a couple of stoplight acceleration contests you realized that the time spent between shifts was wasted, especially if you went up against an automatic, or worse, an auto with a shift kit. With each shift your opponent would gain a small advantage. With practice, you can click off really quick speed shifts by slightly lifting off the throttle with your right foot at the same time you stab the clutch with your left foot and slam the stick into the next gear with you right hand (or left, for those Down-Under and other such exotic places.) Now there is very little loss of acceleration between shifts and you can hang with your buddy’s automatic.
Spending some time at the track helps to refine the technique and prepares you for the final stage in shifting evolution- Power Shifting!
Power Shifting
Ever listen a manual car down the race track? You can tell the good drivers from the not so good simply by the sound of the engine at each shift.
The
Granny Shifters sound like this- Waaaaaaaaa! -moment of silence- Wuh, Waaaaaaaaa!
The good
Speed Shifters sound like this- Waaaaaaa !-tiny delay- Waaaaaaaa! With less rpm drop the engine does not bog down going into the next gear- you might even hear a good Bark! from the rear tires.
The
Power Shifters sound like this Waaaaaaa! WHAA! Waaaaaaa! WHAA! Waaaaaa! WHAA! Waaaaa! and bark the tires in all gears (unless on slicks.) The rpms not only don’t drop- they actually go up between shifts since the throttle is wide open the whole time!
Powershift
The Power Shift Shuffle goes something like this- the gas pedal goes to the floor and stays there- never lift! Preload the stick by pulling on it before you reach your shift point. At the pivotal moment simultaneously KICK the clutch pedal and slam the stick into the next gear. Time it right and you will see the rpms climb 200 to 500 rpm between gears and feel a strong surge as the next gear engages. I started power shifting only the 3 to 4 shift my last track day of 2001. It is the easiest shift, straight back, with time to prepare mentally while 3rd winds out. I was able to knock off a pair of 13.50 runs that day and go home grinning from ear to ear. It was time to go to the next level and see if I could actually improve on those mid-13’s.
