Can you port your own throttle body?
Porting and polishing a throttle body is a relatively easy mod that you can do yourself for free providing you have a rotary tool with some metal working attachments and some metal polish.
Does porting a throttle body help?
If the throttle body is not a choke point, then a ported throttle body will ultimately be a better option because it optimizes air flow without sacrificing velocity. The biggest benefit of a ported throttle body over a bored throttle body is the support for low-mid range power gains.
Can you port and polish heads at home?
The best way to save the most money while reaping the same performance benefits is to invest your own personal time into porting and polishing the cylinder head yourself. It is very easy to grind way too much metal, which is irreversible and will likely deem the cylinder head unusable.
How much HP does porting add?
Porting the heads will definitely help airflow. You will gain 25 HP over the stock setup.
How much does it cost to get your throttle body ported?
Throttle Body Porting starts at $60 small frame and larger frame $80+.
Does a ported throttle body require a tune?
No tune required, the ported TB won’t really add any power but should give you better throttle response.
Does port and polish add HP?
In fact, a good port and polish job adds an additional 10 percent in both horsepower and in fuel economy, so it’s worth it. Start by cleaning the ports and then painting them with layout fluid. Place the high-performance intake manifold gaskets and exhaust gaskets in place and secure them with the bolts or nuts.
How does a throttle body spacer work?
Throttle body spacers are a pieces of metal used to change the airflow into the intake manifold. The spacer is bolted on the back of the throttle body, downstream of the main airflow. It basically directs the flow of air into the manifold to maximize the volume that goes into the intake.
What is intake porting?
Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder heads, as manufactured, are usually suboptimal for racing applications due to being designed for maximum durability.
