How Does a Rear Mount Turbo Work

A rear mount turbo is a type of turbocharger that mounts to the rear of the engine, near the firewall. The exhaust gases from the engine flow through the turbocharger, which spins a turbine. The turbine is connected to a compressor, which draws in air and compresses it before sending it to the engine.

This helps to increase power and efficiency.

Rear mount turbos are a bit more complicated than your average turbocharger. Most turbochargers are mounted on the engine, either on the front or back of it. Rear mount turbos, however, are placed further back in the engine bay, behind the engine.

This has a few advantages and disadvantages. Let’s take a look at how rear mount turbos work and what benefits and drawbacks they have. The main advantage of a rear mount turbo is that it helps to improve traction.

By placing the weight of the turbocharger further back in the car, there is less chance of wheelspin when accelerating hard out of corners. This can be a big advantage on race tracks or rally stages where every tenth of a second counts. It also means that you can put more power down to the ground as there is less chance of wheelspin happening.

The main disadvantage of rear mount turbos is that they can be more difficult to install and maintain. They also tend to run hotter than front or mid-mounted turbos as they are further away from any cooling fans that may be installed in the engine bay.

rear mount turbos **PROS AND CONS**

Rear Mount Turbo Vs Front Mount

Rear mount turbochargers have a few advantages over front mount units. One advantage is that the rear mounted unit will force more exhaust gases through the turbine, providing more power. Another advantage is that the rear mount unit helps to keep the engine bay cooler, as the hot exhaust gases are not close to the engine.

Finally, rear mount turbochargers can provide better traction in slippery conditions, as they help to weight down the back end of the vehicle.

Do Rear Mount Turbos Have Lag?

While there are a number of factors that can contribute to turbo lag, such as the size and design of the turbine and compressor, the location of the turbocharger is also a significant factor. In general, rear-mounted turbos tend to have more lag than front-mounted turbos. This is because the distance that the exhaust gases have to travel to reach the turbine is greater, meaning it takes longer for them to build up enough pressure to spin the turbine.

Additionally, rear-mounting often results in a less efficient flow of exhaust gases due to bends and turns in the piping. However, it’s important to note that there are many other variables that can affect turbo lag, such as engine displacement, camshaft design, boost pressure, and more. So while rear-mount turbos may tend to have more lag than front-mount turbos on average, there are plenty of exceptions to this rule.

Do Rear Mount Turbos Need Intercoolers?

Rear mount turbos do not need intercoolers because they are already cooled by the air that surrounds them. Intercoolers are only necessary for front mount turbos because the air that surrounds them is hot and can cause the turbo to overheat.

How a Turbo is Mounted?

A turbocharger, or simply “turbo”, is a gas compressor that forces extra air into an internal combustion engine. This increases the amount of oxygen available to the engine, allowing it to burn more fuel and produce more power. Turbochargers are typically mounted on top of the engine, between the cylinder head(s) and the exhaust manifold.

This placement allows the turbocharger to quickly spin up to speed as soon as the engine is started, and also keeps it away from high temperatures.

How Does a Turbo Work on a Caterpillar Engine?

Caterpillar engines are widely used in a variety of industries and applications. They are known for their reliability and durability. A Caterpillar engine typically has a long life span, often lasting for decades with proper maintenance.

One key factor in a Caterpillar engine’s longevity is its turbocharger. A turbocharger helps to prolong an engine’s life by increasing its efficiency. It does this by forcing more air into the engine’s cylinders, which allows the engine to burn fuel more efficiently.

In turn, this increases the engine’s power output while reducing emissions. A turbocharger is essentially a type of compressor that is driven by the exhaust gases from an engine. The exhaust gases spin a turbine, which in turn drives the compressor.

The compressor then forces more air into the cylinders, providing the extra oxygen needed for combustion. The increased airflow provided by a turbocharger also helps to cool down an engine, as it allows more heat to be dissipated through the increased surface area of the cylinder walls. This can be especially beneficial in hot climates or when operating an engine at high speeds for extended periods of time.

Overall, a turbocharger is a key component in helping a Caterpillar engine run efficiently and last for many years.


A rear mount turbocharger works by compressing air and forcing it into the engine. This forced induction increases the power of the engine, allowing it to run at a higher level of performance. The compressor is powered by the exhaust gases from the engine, which are directed through a turbine.

The turbine spins the compressor, which pulls in air and forces it into the engine.
