What size throttle body is a 4.6 Ford?

Throttle Body Size for a 4.6 Ford Engine
The stock throttle body size for a 4.6L Ford engine is 70mm. Upgrading to a 75mm throttle body is a common modification for both the 4.6L and 5.4L V8 engines, with an emphasis on the 5.4L due to its larger displacement. Aftermarket throttle bodies can increase throttle response and provide some horsepower gains, but they may lean out the engine slightly.
It’s important to note that the ideal mass air meter should be as big as the throttle body or slightly larger, as the engine will only flow what the size of the throttle body is. Therefore, upgrading the throttle body may also require corresponding upgrades to the mass air meter and the engine’s computer to fully realize the potential for more airflow.
If you’re considering aftermarket upgrades, the BBK Power Plus 75mm Throttle Body is designed to increase airflow and improve horsepower, providing gains of 7-12 HP depending on the vehicle and application. Additionally, moving up to a 90mm throttle body can be a solid choice for improved power and performance, especially for a naturally aspirated 5.0L with some mods.
In summary, the stock throttle body size for a 4.6L Ford engine is 70mm, but upgrading to a 75mm throttle body is a common modification that can provide improved throttle response and some horsepower gains. Considerations for corresponding upgrades to the mass air meter and engine’s computer should also be taken into account when upgrading the throttle body.

How much HP does a 62mm throttle body add?

15-20 rwhp
Replace your restrictive stock throttle body with a SR Performance Throttle body that features a generous, free flowing 62mm twin bore design. By installing a SR Performance throttle body you can expect to see gains power gains of 15-20 rwhp and 20-25 rwtq.

How do I know my throttle body size?

I’ve always used the calculation formula: Engine displacement/number of cylinders x rev limit.. (For the calculation above the constants Being the 0.8 is based on VE avarage at peak for most N/A engines, and the 0.5 being of VE avarage at idle.) So 44mm throttle body be about your ball park to consider.

Do you need a tune after installing a bigger throttle body?

For pre-2005 vehicles, a tune is not required with the addition of a new throttle body. For 2005+ vehicles, a tune is recommended for throttle body changes & updates. Please Note: Some throttle bodies require a tune for installation.

What size throttle body is a Ford f150?

F-150 – 90MM Premium Throttle Body (2010-Present) 5.0L or 6.2L.

How much HP does a 70mm throttle body add?

8-10 Additional Horsepower Over The Stock Throttle Body.

What happens if I put a bigger throttle body on my car?

A larger throttle body can increase the amount of air and fuel entering the engine, resulting in improved performance and increased horsepower. It can also improve throttle response and acceleration.

Does putting a bigger throttle body increase horsepower?

A larger throttle body by itself would have little effect on the performance of an engine. A larger throttle body is needed when other parts such as the intake manifold, cylinder head ports, intake valves, exhaust valves, exhaust ports, exhaust system, etc. are increased in size to flow more air and exhaust.

Will a bigger throttle body make a difference?

Upgrading an entire fuel system typically involves replacing: The throttle bodies: Bigger throttle bodies can provide greater throttle response and increased power. Fuel injectors: High-flow fuel injectors can improve the air/fuel mixture for more efficient combustion.

Is a bigger or smaller throttle body better?

Contrary to popular belief, a larger throttle opening does not reduce low-speed power, but the effect on throttle response can be dramatic. The reason is that (compared to a smaller throttle body), any throttle position will offer a sizable increase in airflow.

What does a 80mm throttle body do?

This aFe POWER 80mm Throttle Body and adapter kit improves engine air flow over the stock 74mm throttle body. The extra air flow will increase horsepower and throttle response. Performance gains will be more noticeable as more upgrades are added to the vehicle.
