Aftermarket Mustang Throttle Bodies
Throttle bodies can be one of the main choke points in a Mustang’s exhaust system as all of the air your intake sucks in has to pass through the throttle body, condensing before it goes into the intake manifold. When looking to achieve higher power numbers and improved acceleration/throttle response, a throttle body is often the key.
For low key, builds, throttle bodies are often not needed, but when you starting trying to go for bigger power increases you will need to upgrade the throttle body. If you go to a forced induction setup with a supercharger, turbocharger, or even nitrous, you will definitely need to replace the stock throttle body with a much wider one.
Mustang throttle bodies can add anywhere from 5-20 HP depending upon the size and your other supporting mods. Not all throttle bodies need to be tuned, however it will without a doubt deliver more power and a much smoother throttle response with a custom tune.
Differences Between Single & Dual Bladed Throttle Bodies
Throttle bodies will have either a single moving opening or dual openings/throttle blades. Typically, single blade throttle bodies (like what is found on the stock setup) are more efficient as they have less impeding the flow of air into the engine; however, large dual blade throttle bodies can perform well and offer an increase in power as well. Single blade bodies tend to make more power than duals, but it really varies on a case-by-case basis.
There is also a difference in single blade throttle bodies between circular and oval throttle bodies. Circular ones are what the Mustang has stock and offer quick, snappy throttle responses.
Oval Mustang throttle bodies are needed for supercharged applications and some intake manifolds and can suck in more air than a circular body. Oval bodies are like a fusion of a single circular blade and a dual blade throttle body, but without the air blockage.
Oval Mustang throttle bodies require more careful tuning as they can suffer from throttle hand, where the throttle body blade closes slower than you release off the throttle, hanging open.
