Gauges are devices that monitor different aspects of a car like exhaust and intake temperature, air-fuel ratio, boost, oil, RPM (Revolution Per Minute), etc. Modded cars are fitted with many aftermarket gauges compared to stock ones because most modded cars are classic. They don’t come with an extra gauge. Many older cars have fewer gauges. They’re frequently faulty or wrong. To get an idea of what’s happening in the car, it is best to fix aftermarket gauges. Prosport gauges are an excellent option for modded cars. Prosport gauges are, in fact, one of the best gauges available in the market.
A tachometer / RPM gauge is used to measure the rotation speed of a shaft. The device will display the RPM (Revolution Per Minute). The working principle of a tachometer is a bit complex. An electronic tachometer has the same principle used in the old analogue voltmeter. The engine speed is converted to a voltage that is applied to the moving coil. With the applied voltage, the coil creates a magnetic field. That region of the coil attempts to adjust itself with the magnetic field of the magnets. It causes the coil to move front in the spring, deflecting the needle. And by combining the number of turns in the rotating coil, the strength of the spring, input voltage and the strength of the magnet, a ratio is achieved so actually the needle will deflect according to the number of degrees per volt.
Oil catch cans
It is a great idea to fix an oil catch can in a direct-injection engine. The oil catch can is set in between the valve cover and the intake manifold. A hose will be joining them with the positive crankcase ventilation system. During combustion, high pressure on the top of the piston, called blowby, will pass the piston and pressurise the crankcase in the area underneath the piston. The positive crankcase ventilation system is used for the pressure, so the high pressure in the crankcase will be moved to the intake manifold. In this process, some oil mess in the engine will also travel to the intake manifold via the positive crankcase ventilation system. The oil will hit the intake valves and build a deposit on the intake valve. The idea behind the oil catch can is that it will catch the oil from the crankcase and collect it without it going inside the intake valves.
Manual boost controller
It will be installed in line between the boost pressure source and the wastegate actuator. It features some form of manual adjustment with an adjustment knob on top of it. Inside it, there will be a little ball and a little spring changing. The adjustment of the boost controller changes the amount of spring pressure exerted on the ball. The little ball will delay the boost pressure from reaching the wastegate actuator because the little ball needs more pressure than the wastegate actuator to rise from its position. It forces the turbo to generate more pressure to raise the ball and reach the wastegate actuator. Installing a manual boost controller is very easy. It roughly takes 15 – 20 minutes, but getting the desired boost takes a lot of trial and error, involving combining a manual boost controller to an aftermarket wastegate actuator that can house different springs inside it. It can change the nature of the turbocharged engine.
