Performance Where You Need It

The engines that have been admired over the history of the automotive industry are often the ones that have given us more performance and speed than in most other engines. What makes these engines special is the way they respond to the gasoline, oil and air that mixes and produces the explosion and the power inside the cylinder. While most of the daily driver engines that you find are fine with a manifold and a single throttle body, the difference is huge when you have individual throttle bodies on an engine that you’re expecting higher performance from.

When and engine has individual throttle bodies it has a butterfly valve that regulates the air intake for each cylinder. This makes it easier to get the air to all the cylinders at the same time. Typically the way this works is through the use of atmospheric pressure that builds outside each cylinder to give you the instant air entry you need. Engines with these individual throttle bodies on the m don’t need a manifold to pull the air in and share it among the cylinders present inside the engine. Let’s take a closer look at how this works.

In a shared system the throttle body butterfly valve is located prior to the manifold in the order of operation. This single throttle body that’s used for all cylinders as a shared system allows the air in but the air won’t make its way to the cylinders at the same time and it takes longer for the air to get to the cylinders which lower the performance. Even when an engine uses an individual throttle body setup it can uses a manifold to help with the filtering of the air that travels into the cylinders to be used during the compression of the engine.

Another advantage is the space that has to be filled with air as you press on the accelerator. With an engine that uses individual throttle bodies the atmospheric pressure can instantly active at the acceleration you want to give you the throttle response you’re looking for. In a system with a single throttle body the entire intake manifold has to be filled along with the throttle valves that lead to each cylinder. This takes longer and causes you to experience a delay in the throttle response you want, especially when you take your car out to the track.

For most engines you’re going to enjoy the benefit of a single throttle body because it’s acceptable and efficient for you when driving. If you’re searching for a performance engine all you need is to look for the ones that have an individual throttle body setup to give you the power and performance you want to enjoy. Check out this video from Engineering Explained and learn more about how these two different types of engines work to give you the right way to drive your car and enjoy the benefit of a great way to have the engine throttle response you want for the ride you’ve been looking for.
