Do bigger fuel injectors increase horsepower?
Do bigger fuel injectors increase 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.
What happens if you put bigger fuel injectors?
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 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.
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).
How do I choose injectors size?
Injector Math: How to Calculate Optimum Fuel Injector Size
- Step 1: Determine Horsepower.
- Step 2: Determine Approximate BSFC (Brake-Specific Fuel Consumption)
- Engine Type BSFC Using Gasoline.
- Step 3: Determine Your Safe Duty Cycle.
- Step 4: Calculate Your Optimum Injector Size.
- Step 5: Fine-Tune the Flow.
Do I need a tune after bigger injectors?
Do you need a tune for fuel injectors?
Fuel injectors directly affect the air/fuel ratio for the engine and new fuel injectors do require a new or updated tune.
What size fuel injectors should I use?
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 |
Do I need a tune after new injectors?
Fuel injectors directly affect the fuel / air delivery of your vehicle. New fuel injectors do require a new or updated tune.
