H Drive Racing Dog Box Transmissions - TOYOTA VITZ SEPANG CIRCUIT
H.DRIVE RACING Products Website: http://www.hdrive-racing.com Email: info@hdrive-racing.com Dog Box Transmission on Toyota VITZ Super 1500 - SEPANG INTERNATIONAL CIRCUIT H.Drive Racing Dog Box Transmissions Dog engagement is normally used in racing applications where fast, precise shifting is needed. Dog gear engagement is facilitated by numerous large teeth (dogs) that mate into matching openings machined into the opposite surface of the drive gear. Unlike the synchro engagement, there is no synchronizing mechanism to assist in equalizing speed. Ideal gear selection—e.g. minimal clashing and wear of the dog rings—is achieved by quick shifts; the motto here is "the quicker the better", so bang away. There is no depressing the clutch in the conventional sense like with the synchromesh transmission. A momentary break in engine load until the shift is achieved by a quick throttle blip or clutch depression. The driver will then experience the dog ring engaging with the next gear and the throttle can be reapplied. With practice this can be done in milliseconds. In fact, a driver can preload the stick shift in the direction of the next shift, and then when he either blips the throttle or clutch the shifter will quickly click in the desired gear. With all else equal, dog-engagement gears are much stronger than synchro-engagement gears because without needing to make space for synchro rings, the gears themselves can be made thicker. The number of dogs (teeth) and the size of the openings determine the window of opportunity that the dogs have to engage during the shift event. Rings with a smaller number of teeth provide a more efficient, smoother shift quality. The downsides to this easier engagement are increased noise and abruptness on the shift.

Four Rings Racing - Dog-Box Tranny Break In Sounds
Breaking in the new straight cut, dog-box transmission at Thunderhill Raceway. Ran a few seconds slower than our normal times getting used to the new feel of the car, but we'll be shooting for some better times next month. The sounds from the video are from the pedal area, and the whine you hear is the tranny. Anyways, enjoy!
