Need a Boost? | Forced Induction vs Natural Aspiration

There are four ways to give your car a major boost in power. 

Adding a shot of nitrous is one. But it can work with any of the three techniques in raising power in your engine – which we we’ll talk about quite extensively.

We know for a fact that naturally aspirated can’t be beaten when it comes to throttle response. Thus, some tuners prefer to keep it that way. So, what do they do to raise power? They make the engine bigger.

They live by the “There is no replacement for displacement” adage.

You see, the main reason for increasing displacement is introducing more air into the combustion chamber. More power requires more air.

The amount of power an internal-combustion engine can produce depends primarily on how much fuel it can burn and how quickly and efficiently it converts that heat to mechanical force. But fuel requires oxygen to combust, so an engine's maximum output depends largely on how much air it can take in to burn that fuel.

To them boring and stroking up to an engine maximum allowable displacement is the best solution so they could still have the instantaneous throttle response they long for. But there is a limiting factor for this which is called the engine block. An engine can only be bored and stroked so much until it can’t.

Hence the concept of forcing-feeding an engine more air than it would normally ingest so that it can burn more fuel and produce more power. This additional intake air can be supplied by either a turbocharger or a supercharger. Both are air compressors, but they operate and perform very differently.

What do you do then? Look for a bigger engine block? That will make your car heavier and potentially lose its balance. That will also be more weight loss from your wallet.

Luckily, we have such things as Supercharging and Turbocharging; or the concept of forcing-feeding an engine more air than it would normally ingest, so that it can burn more fuel and produce more power. 

But with great power comes great responsibility. Hence, the boost controller.

What is a Boost Controller and What does it do?

A boost controller is a device to control the boost level produced in the intake manifold of a turbocharged or supercharged engine by affecting the air pressure delivered to the pneumatic and mechanical wastegate actuator.

A boost controller can be a simple manual control that can be easily fabricated or included as part of the engine management computer in a factory turbocharged car. The other one is an electronic boost controller.

A mechanical boost controller offers up to two boost settings set by the driver and controlled via a switch. They are easy to fit, simple in operation, and require very little maintenance. In essence, a manual boost controller can make your car from Dr. Jekyll levels of civility to Mr. Hyde levels of wild.

Electronic boost controllers, on the other hand, are a far more sophisticated solution offering a host of boost settings mapped against different triggers like gear change, time, rpm, or a manual switch. Electronic boost controllers require a higher level of technical knowledge to be fitted but offer greater flexibility and countless features.
