What do bigger injectors do on a diesel?

Bigger Injectors Are Quicker-Firing Injectors

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. Electrical discharge machining (EDM) is the most common means of enlarging the holes in a fuel injector nozzle.

Do bigger injectors increase power?

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. There is a catch, however. Go too large and you can lose power.

What will bigger fuel injectors do?

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.

When should I upgrade my diesel injectors?

Diesel fuel injectors generally have a shorter lifespan than their predecessors, meaning they need to be replaced more frequently for optimal performance. The life expectancy of a good quality diesel fuel injector is around 150,000 kilometres. They should be checked out by a professional at around this time.

Does changing fuel injectors improve performance?

A new or upgraded fuel injector can improve engine performance, reduce diesel emissions, and increase the uptime of your truck. Don't wait for a better system to come on the market, though, because when it's worn out, part of the fuel injector – or even the entire system – should be replaced.

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

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).

Do fuel injectors add HP?

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.

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.

What happens if you put bigger injectors on a stock motor?

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.

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.

Will new fuel injectors make a difference?

Fuel injectors do not change performance, but rather an engine change, not a performance upgrade such as a low restriction air filter. Fuel delivery is something which is explained in detail by experts. When using incorrectly, upgrading fuel injectors may result in a decrease in engine power.

How do you increase horsepower and torque?

How do you improve engine performance?

Can you drive with bigger injectors?

No. If it even starts, you will risk bore-wash. Either tow it, or do the pump/rails yourself but leave the stock injectors, and swap in the bigger ones at the tuner's place.

What brand of fuel injectors are best?

How do I choose an injector?

Which is better high or low impedance injectors?

That low-amp current keeps the injector temperature lower, which makes it more reliable; that's why the high-impedance design is the most common injector style for OEM applications. Low-impedance injectors, also called peak-and-hold injectors, are sent a more powerful electrical signal, usually around 56 amps, to open.

How much HP will 120lb injectors support?

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

How much horsepower will 60lb injectors support?

60' will support 600+ rwhp with pump fuel...not the case with e85 at those levels!

How often do fuel injectors need to be replaced?

Some fuel injectors are rated to last one billion cycles or approximately the lifetime of the vehicle. But when you factor in the adverse conditions experienced in real-world driving coupled with a lack of proper maintenance, most fuel injectors might need to be replaced every 50,000 to 100,000 miles.

Is injector cleaner worth it?

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.

Do I need a retune after replacing injectors?

Fuel injectors directly affect the air/fuel ratio for the engine and new fuel injectors do require a new or updated tune.
