How much HP does performance fuel injectors add?
10-20 more
Larger throttle body and injectors A larger high-performance throttle body will deliver more horsepower. Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque.

Is throttle body injection the same as fuel injection?
Throttle body injection is a type of fuel injection system that served as a segue between carburation and multiport fuel injection. A typical TBI assembly has a fuel metering body that sits on top of the throttle body.
What type of fuel injection is best?
Direct injection In the previously mentioned systems, the fuel is sprayed on the intake and there is always a potential of fuel condensation to some extent. However, in the DI system, all the fuel is directly injected into the cylinder which produces maximum fuel economy and this is its greatest advantage.
What are the 2 types of throttle body?
The throttle is either open or closed (although there is always a small hole or other bypass to allow a small amount of air to flow through so the engine can idle when the throttle is closed), or some intermediate position.
What injector size do I need?
of fuel per injector at an 80% (0.8) duty cycle….Flow Rate Definition, Calculating Horsepower Range.
| Injector Flow Rate | Naturally Aspirated Engine | Engine w/ Power Adder |
|---|---|---|
| 19 lbs./hr. | 225-290 hp | 185-240 hp |
| 24 lbs./hr. | 280-360 hp | 240-300 hp |
| 30 lbs./hr. | 350-450 hp | 300-375 hp |
| 36 lbs./hr. | 425-540 hp | 350-450 hp |
How do I choose a throttle body?
The general rule is: the bigger the size, the higher the RPM needed for a kick of power. If your new throttle body is too big your vehicle will feel tired at lower RPMs, while really taking off powerfully at higher RPMs (when the engine’s demand of air flow matches up with the the internal bore’a bigger size).
