What happens if you use bigger fuel injectors?
Larger throttle body and injectors Go too large and you can lose power. Not every engine is well suited to a larger throttle body, which means you have to do your homework ahead of time.
Do fuel injectors affect gas mileage?
Having bad fuel injectors can cause bad mileage. This is because the fuel injectors are responsible for putting fuel into the engine. This causes more fuel to be used, and will use up more gas than you need. Same goes for revving your engine.
Are bigger fuel injectors better?
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.
Can you run bigger fuel injectors on a 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.
What size injectors do I need for 500hp?
Flow Rate Definition, Calculating Horsepower Range
| Injector Flow Rate | Naturally Aspirated Engine | Engine w/ Power Adder |
|---|---|---|
| 30 lbs./hr. | 350-450 hp | 300-375 hp |
| 36 lbs./hr. | 425-540 hp | 350-450 hp |
| 42 lbs./hr. | 500-625 hp | 410-525 hp |
| 46 lbs./hr. | 540-690 hp | 450-575 hp |
Do I need a tune with 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).
How can I get more miles per gallon?
Fuel Economy Tips: How to Get More MPG
- 10 BEST FUEL ECONOMY TIPS.
- 1 – DRIVE STEADILY. Engines burn more fuel by accelerating and decelerating than by travelling at a constant speed.
- 2 – AVOID HEAVY BRAKING.
- 3 – STOP OVER-REVVING.
- 4 – CHECK YOUR TYRES.
- 5 – SLOW DOWN.
- 6 – TURN OFF THE ELECTRICS.
- 7 – DON’T COAST.
Why does my MPG go down when idling?
Dirty or worn out spark plugs affect the way your engine burns fuel in the combustion chamber. Worn out spark plugs causes gas to be left unburned, wasting it. In turn, this waste means your getting fewer miles per gallon.
Do bigger injectors need a tune?
Do you need a tune for upgraded injectors?
Fuel injectors directly affect the fuel / air delivery of your vehicle. New fuel injectors do require a new or updated tune.
How do I choose injectors size?
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.
Do bigger fuel injectors give more fuel to the engine?
Larger fuel injectors can deliver more fuel to the engine, but a larger fuel pump is also needed to supply the injectors. Problem with just adding larger injectors | The higher the fuel pressure, the harder the fuel pump has to work and more electrical energy is required to open the fuel injectors.
What are performance injectors and how do they work?
These injectors can help your engine perform at maximum capacity and boost your fuel economy. Performance injectors work by delivering more fuel into the combustion chamber, greatly increasing your vehicle’s power and performance.
How much more horsepower does a bigger throttle give?
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. Also remember that a larger throttle requires higher-flow fuel injectors.
How much HP will 24 lb injectors support?
How much horsepower will 24 lb injectors support? Ford 24 lb injectors are rated at 39.5 PSI since he is running at 42 PSI the injectors are actually running at 25 lbs per hour. An engine making 600 HP with a very good BSFC number of . 33 lbs /hp (very rare) could run on injectors of 25 lbs /hr with 100\% duty cycle.
