Sequential gearboxes

However, the taller 1st gear demands that the clutch be slipped a little more in order to get the car moving and the shorter top gear may limit top speed. The original Fortin 5 speed has evolved during the past 20 years into a complete line up of gearboxes including 4 and 5 speed "H" pattern gearboxes and 4, 5 and 6 speed sequential gearboxes.

The speed of the shift is limited only by how quickly the driver can move the shifter and in some cases the shift can be made without disengaging the clutch. With the "H" pattern, the location of the shift lever changes, so you have to think about where to put your hand depending on which gear you are in.

You can see that there are grooves cut into the drum. The "H" pattern allows you to move the shift rod between the control rods for the three forks and move the rods back and forth. A sequential gearbox gives the driver several important advantages that are very useful in a race car.

Available for a variety of popular vehicle installations and drivetrain formats, Quaife motorsport gearboxes use high strength, contemporary tooth form technology and gear engagement design combined with wide shaft centre layouts. The same would apply here for the sequential RS box, no difference.

I spent over months researching and testing various transmission to make sure we used the best option on the market. Every motorcycle I've ridden in the last 45 years and there's been a lot, has a dog sequential gearbox. For example, to go from 2nd to 3rd gear on the "H" pattern, you have to push the lever up, over and up again.

The constant vigilance required is a little too thought-consuming to be comfortably driven by most. Simply put, the best way to shift is as quickly as possible. It truly is a transmission solution capable on both the street and the track.

The car has a sequential six-speed transmission, so instead of the H-pattern seen on a normal manual transmission, the shifter moves in a straight line. Holinger Sequential Gearboxes The finest most robust sequential gearboxes at realistic prices, these gearboxes are capable of withstnding serious BHP and have a fantastic reputation in long distance 24 hour events.

No rolling up to the lights in 3rd or 4th and slipping it into neutral and using the brakes only.


It is a much faster way to shift. Image courtesy Quaife Engineering Ltd. That can never happen with a sequential gearbox. Quaife's range of Clubman and heavy duty H-pattern synchromesh gearboxes retain the standard synchromesh engagement parts from the original gearboxes, and offer optimised gear ratios for motorsport to make the most of the power and torque from the engine in any given gear.

Quaife Sequential Gearbox for the RS

It turns out that most race cars use sequential gearboxes as well. This enables the transmission of higher torque loadings than road transmissions and faster ratio selection, while users can exploit a choice of close ratio gear sets and final drive ratios where available to further optimise performance.

A straight cut gear is typically used for a racing application because when load is applied to the gear teeth there is no, or very little, axial thrust Sequential gearboxes to the resulting forces generated.

Though, it has to be said that the addition of these quick-shifting gearboxes makes the Ford Focus seem so much faster than its horsepower might suggest. The ability to shift gear without using the clutch reduces the time spent off the power and allows drivers to get back on the power sooner, resulting in faster overall race times.

How do the ratios in this kit compare with OEM ratios? To put the transmission in nuetral shift down to 1st and then down again. To a wise and mechanically sympathetic driver, a dog box is streetable. If you're not living on the edge you're taking up too much space.

Ford and Volkswagen have been major proponents of this technology, which improves fuel economy and makes for a seamless shift and a smoother driving experience.4 or 5 Speed dog engagement transaxle transmission with H-Pattern or Sequential shift types.
