Diagram of a car undergoing fishtailing. Video of a car fishtailing or drifting on the street of Riia maantee in Tartu, Estonia (December 2021) Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in oversteer. This can be caused by low-friction surfaces (sand, gravel, rain, snow, ice, etc.).
The Turbo-back (or turbo back) is part of the exhaust system from the outlet of a turbocharger to the final vent to open air. Turbo-back systems are generally produced as aftermarket performance systems for cars with turbochargers. Some turbo-back (and header-back) systems replace stock catalytic converters, while others have less flow restriction.
The farther back the engine, the greater the bias. Typical weight bias for an FF (front engine, front-wheel-drive) is 65/35 front/rear; for FR, 55/45; for MR, 45/55; for RR, 35/65. A static rear weight requires less forward brake bias , as load is more evenly distributed among all four wheels under braking.
Top: Lateral view; the red circles mark the front air dam/splitter and rear diffuser. Bottom: Rear. A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere.
The draught tube routes all blow-by gases back into the intake mixture and is usually located between the air filter and carburetor. Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube.
Silencer (silver) and exhaust pipe on a Ducati motorcycle A silencer cut open to show the insulation, chambers and piping inside the shell. A muffler (North American and Australian English) [1] or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an ...
The layout of a 4-2-1 system is as follows: four pipes (primary) come off the cylinder head, and merge into two pipes (secondary), which in turn finally link up to form one collector pipe. [ 2 ] Compared with a 4-1 exhaust system, a 4-2-1 often produces more power at mid-range engine speeds (RPM), while a 4-1 exhaust produces more power at high ...
There are also aftermarket units where a separate controller is installed using a custom RPM setting. A limiter prevents a vehicle's engine from being pushed beyond the manufacturer's limit, known as the redline (literally the red line marked on the tachometer). At some point beyond the redline, engine damage may occur.
