![]() Customer must provide transmission or we can sell you one. This does not include labor, shipping or the donor transmission. Pricing: For full sequential gear sets the prices start at $16,999 for Corvette $17,999. Note- For stock case applications is the 1 to 1 6th gear requires the billet case upgrade which is designed to work without any issues due to the size of the gears. Gears have been successfully tested behind engines with 1500hp/1100kw and 1200ftlb/1600nm in race conditions. Helical Cut 3.255 / 2.148 / 1.561 / 1.228 / 1.000 / 0.857 This sequential transmission is totally streetable and generates less heat than competitors. EFI highly recommended for full integrationĬan be used with the following Tremec transmissions.Customized input shaft for Ford or GM applications.Optional billet front cover with oil pump fittings and spray bar -$999.It turns out that most race cars use sequential gearboxes as well. Programmable gear position display included This type of transmission is called a sequential gearbox or a sequential manual transmission.Billet case upgrade available for the ultimate in strength and clearance -$4999.Can be used with a manual shifter(included in the kit) or optional paddle shifter- Paddle Shifter option -$7999.Full 6-speed with custom gear ratios available see below for models.For that job, a sequential gearbox is the better choice. But none of that matters in a race car, where it's all about getting the power to the ground as quickly and efficiently as possible. The Sadev gearbox's lightweight flywheel and tiny clutch also make it pretty much useless for low-speed driving. Sequential gearboxes are loud, and require significant force to engage gears. VW's DSG transmission shifts quickly, but it's also designed to be smooth and quiet. Overall, the main difference between a sequential and dual-clutch transmission is that one is designed for racing, and one isn't. Straight-cut gears make a high-pitched whine, but they also transfer power from the engine to the wheels more efficiently. Helical-cut gears have angled teeth, allowing them to mesh more smoothly. the DSG transmission (and all transmissions designed for road cars) uses helical-cut gears, while the sequential 'box uses straight-cut gears. FCP Euro reckons it's about 100 pounds lighter than the DSG, too. This transmission also allows for equal-length axles, helping to control torque steer in the front-wheel drive GTI TCR race car. ![]() On downshiftsas in Ferraris 155,000 360 Modena F1the system. That allows for no-lift shifts, but also requires the use of a rotating barrel instead of shift gates. Both controls initiate a sequence in which the throttle is closed, the clutch is disengaged, and the shift mechanism is activated. The sequential gearbox has all of its gears lined up on one input shaft, and they engage the output shaft using dogs. They're positioned on either side of an output shaft, which sends power to the axles (one of which is shorter than the other), and engage the shaft using synchronizers, just like other modern road-car transmissions.Ģ018 Volkswagen Golf GTI TCR (Photo by FCP Euro) The TCR-spec DSG has two input shafts, each with three gears. The internal layouts of the two transmissions are very different. That provided a good opportunity for a gearbox comparison, as the TCR race cars started out with a modified version of VW's Direct Shift Gearbox (DSG) dual-clutch transmission used in the GTI road car, but were later upgraded with Sadev sequential transmissions. In addition to selling parts, FCP Euro has a race team that ran the Volkswagen GTI TCR for two seasons. This video from parts supplier FCP Euro explains the differences between these two types of transmission. Sequential and dual-clutch gearboxes both allow you to manually select gears without a clutch pedal, but that doesn't mean they're the same. ![]()
