Why might you choose to use an aftermarket throttle body?
One of the few reasons to change to an aftermarket throttle body is performance. The throttle body is a common bottle neck that may restrict air flow. This restriction comes from one of two places. The engine has had upgrades or some kind that allow it to “breath” better.
Why is the throttle body a bottle neck?
The throttle body is a common bottle neck that may restrict air flow. This restriction comes from one of two places. The engine has had upgrades or some kind that allow it to “breath” better. While the throttle body was not restrictive before the upgrades, now that the engine thirst for more air the throttle body becomes a bottle neck.
Can a throttle body be a limiting factor?
Yes, good one. There’s no advantage to be had if the throttle body isn’t the limiting factor. Crude example – if the chosen throttle body is so big, that at 80% throttle opening, it’s able to provide the engine with all it’s airflow requirement, then opening it further does nothing.
How to upgrade throttle body on new car?

Is the intake throttle body hogged or hogged?
There are a number of other upgrades, 1.6 rockers, 1-3/4 headers, Corsa exhaust, high flow cats, 2800 stall converter, 3:45 Dana 44 so I can’t be sure of the throttle body contribution. The intake throttle body mounting flange is hogged to match.
Do you need a larger throttle body for a bolt on?
True, that’s a lot of money for a throttle body, and although I’d still recommend a set of headers/exhaust/gears before I’d recommend a larger throttle body, I can now honestly say, that a larger T.B. will definitely NOT hurt performance on a bolt-on LT1, only improve it.
Who is the manufacturer of the throttle body?
The throttle body you see below is made by TPIS. It’s a pretty pricey piece at $450 but the product itself is an absolute work of art. They’re machined out of a solid block of aluminum. They have CNC machined throttle blades.
