Frequently Asked Questions (FAQs)
1. Is throttle body injection good?
Throttle body injection (TBI) systems can be a good choice for your engine setup, especially if you plan on future upgrades like a power adder or timing control. However, it's important to choose the appropriate TBI system from the start to ensure optimal performance.
2. What are the disadvantages of throttle body injection?
One disadvantage of throttle body injection (TBI) is that it can lead to higher condensation and fuel puddling in the manifold. The manifold cools faster, causing fuel to condense and puddle in the interior. This longer travel distance from the throttle body to the combustion chamber increases the likelihood of fuel condensation and puddling.
3. Does a throttle body use injectors?
Yes, a throttle body injection (TBI) system uses a single injector mounted in a throttle body, similar to a carburetor. The fuel is mixed with the air before entering the intake manifold, just like in a carbureted induction system.
4. Do throttle bodies add horsepower?
Adding a throttle body can result in added horsepower, but the gains will depend on other engine modifications as well. Typically, a throttle body can provide a horsepower increase ranging from 5-25 HP, depending on the specific modifications made to the engine.
5. Does a throttle body make a car faster?
Throttle bodies are designed to improve airflow and increase the amount of air/fuel mixture entering the combustion chamber. By optimizing airflow, a throttle body can help increase engine power. The ability to get more air/fuel in and out of the engine quickly contributes to making the car faster.
6. How much fuel pressure does a throttle body injection need?
The required fuel pressure for throttle body injection (TBI) depends on the fuel system being used. In a returnless system, the fuel pressure can vary between 30-75 psi. For a regulated return system, the required pressure will depend on the horsepower of the engine, with most vehicles needing around 45 psi and engines pushing 600hp requiring closer to 70 psi.
