What do bigger injectors do on a car?

The larger the diameter, the more fuel an injector can deliver. As fuel injector size increases, there are some unwanted side effects. As an injector's hole gets bigger, the minimum amount of fuel it can flow also gets larger.

Do bigger injectors increase horsepower?

3. 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.

What will happen if I put bigger injectors in my car?

It's easy to fall into the trap of thinking that bigger fuel injectors equal more power, but unless your engine is set up to deal with the extra fuel, you'll be on a fast track to trouble. The excess fuel will flood the engine and it either won't run at all, or will be running too rich.

Is upgrading fuel injectors worth it?

Changing fuel injectors is not a “plug-and-play” performance upgrade, such as installing a low restriction air filter. It's something that requires knowledge about how the fuel delivery system works. In fact, upgrading fuel injectors may actually decrease the engine power if done incorrectly.

Do bigger injectors need a tune?

In general, injectors need a tune. Otherwise, your ECU is trying to drive the new, bigger injectors using the duty cycle and dead times for the old, smaller injectors, which means too much gas potentially at the wrong time (i.e. - running rich and potentially missing).

? Fuel Injectors - Is Bigger Really Better? | TECH TUESDAY |

Can I put bigger fuel injectors stock car?

You can;t do a stock tune unless you can fool the ecu into thinking it is getting more or less air. If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in.

Will bigger injectors hurt mpg?

So, as long as the gas pedal can be kept under control with the new power from the larger injectors, there will not be much of a change in average miles per gallon, if any at all.

Can fuel injectors add horsepower?

The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.

How can I get more power out of my engine?

How do you increase horsepower?

How do I choose fuel injectors?

Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. It is listed in pounds per hour (lbs./hr.) or cubic centimeters per minute (cc/min.). The right size injector can supply enough fuel under full load conditions at an 80% duty cycle.

How do I choose injectors size?

What brand of fuel injectors are best?

What does a fuel pump upgrade do?

An upgraded fuel pump may move so much fuel, the factory regulator cannot bleed off the pressure fast enough. This leads to higher than desired fuel pressures which means the injectors are spraying more fuel than intended.

How can I improve my car's performance?

How can I make my car run better?

Is fuel injection cleaner good for your car?

A good fuel injector cleaner can improve fuel economy, gas mileage, and vehicle performance. It helps lower maintenance costs by keeping the engine clean. A clean engine delivers more power and better performance because it doesn't have to work as hard.

What do bigger injectors do on a diesel?

Bigger Injectors Are Quicker-Firing Injectors

Thanks to larger nozzles and the appropriate injector body work, the added fuel can be injected quicker. This means less timing advance (i.e. start of injection) to achieve your power goals, which translates into less stress placed on the engine's rotating assembly.

Do you need a tune for fuel injectors?

Fuel injectors directly affect the fuel / air delivery of your vehicle. New fuel injectors do require a new or updated tune.

How much power can 1000cc injectors handle?

The 1000cc Injectors can support 650+whp.

How much HP will 120lb injectors support?

Rated injector flow: 120 lb/hr @ 43 PSI. Supports up to 1900 horsepower.

Are all injectors compatible?

If the body of your car's injectors is gray, keep in mind: injectors of all releases ARE compatible! So, your car can have injectors with a different release for each cylinder!
