Junior Dragsters. The Junior Dragster or Jr Dragster is a scaled-down version of the top fuel dragster. The cars were developed in New Zealand in 1988, with classes developed by the New Zealand Hot Rod Association. [1] The National Hot Rod Association in the USA began sanctioning the class in 1991, with the JDRL (Junior Drag Racing League). [2]
The designation of wide versus close ratio affected the lowest gear ratio; [7] for example, the four-speed Muncie transmissions offered in General Motors performance vehicles included the M20 "wide ratio" transmission, which had a first gear ratio of 2.52 or 2.56:1, while the M21 and M22 "close ratio" transmissions had a first gear ratio of 2. ...
The "MH1" 4T80-E is able to handle vehicles up to 8000 lb (3628.74 kg) GVWR. The final drive ratio is 3.11:1, 3.48:1, or 3.71:1. The 4T80 uses a viscous torque converter clutch, which was replaced with EC3 (electronically controlled converter clutch) in 2005.
The gear range is difference between the highest and lowest gear ratios and may be expressed as a percentage (e.g., 500%) or as a ratio (e.g., 5:1). Heel [ edit ]
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
In a typical CVT, the gear ratio will be chosen so the engine can reach and maintain its maximum-power speed as soon as possible (or at least, when at full throttle, in a partially load-dependent system), but in a semi-auto, the rider is responsible for this choice, and they can ride around all day in top gear (or first) if they so prefer.
Sequential manual transmissions, which are commonly used in motorcycles, ATVs, and racecars, are a type of non-synchronous (unsynchronized) manual transmission, where gear ratios must be selected in succession (order), hence direct access to a specific gear ratio is not possible. [2] Most manual transmissions in modern passenger vehicles are ...
The Chrysler NSG370 is a six-speed overdrive manual transmission sourced from Mercedes and built in the Stuttgart Transmission Plant. [1] It is Jeep's first six-speed manual transmission and Chrysler's second after the Dodge Viper T-56. The NSG370 does not use standard gear oil for lubrication. This transmission utilizes bronze synchronizer ...
