What happens when you install bigger injectors?

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 bigger fuel injectors do anything?

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.

Do bigger fuel injectors increase 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.

Do I need a tune after bigger injectors?

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).

Can I put bigger injectors on stock engine?

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.

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

Will bigger injectors hurt mpg?

In the end, do not upgrade to larger injectors in an attempt to get better fuel mileage, as new stock sized injectors will do the job if your current injectors are worn out. But at the same time, if you are looking for more power, do not be afraid to go to a larger injector because of losing fuel economy.

How do I choose injectors size?

Is it worth upgrading fuel injectors?

In reality, if your car is modified to the point at which you need upgraded fuel injectors, you realistically need an upgraded fuel delivery system for optimum results. If done right, an upgraded fuel system will create an atmosphere where the engine can make more power, reliably and efficiently.

How do bigger injectors work?

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.

How much HP will 36 lb injectors support?

Rated injector flow: 36 lb/hr @ 43 PSI. Supports up to 575 horsepower.

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.

How many pounds are 1000cc injectors?

1000cc/min injectors would equate to 95.2 lb/hr.

How much HP will 120lb injectors support?

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

How much HP does injectors add?

Larger throttle body and injectors

Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque.

How can I add 100 horsepower to my car?

What makes an engine rev faster?

Lower piston speeds means less stress on the connecting rods and crankshaft as well as acceptable flame propagation speeds, allowing the engine to rev even higher. Also, by having a wider bore, you can have larger intake and exhaust valves, leading to better airflow at high RPM.

Does high RPM hurt engine?

The absolute most stress on an engine occurs at high RPMs. The forces acting upon the rotating assembly are exponentially increased with RPM. That also increases the magnification of any oiling inconsistencies (as small as they may be nowadays), which can be deadly to engines.

Why is 7000 RPM the limit?

Petrol engines usually redline at 7000-8000 RPM while diesel hits the peak at around 4500 RPM. This is because diesel engines are not made for high RPM in the first place. They are slow to combust than petrol and are mainly focused on more torque rather than RPM.

What is the fastest RPM ever achieved in a car?
