How do I know if I need bigger fuel injectors? Running too lean At the other end of the scale is where you’ve modified the engine but the injectors aren’t delivering enough fuel to keep up. If you’ve added a turbo, a higher flowing fuel pump, a bigger exhaust and remapped your computer, you’re going to need bigger fuel injectors.

Do you need a tune for 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).24.07.2014

What will bigger injectors do?

Bigger injectors will deliver more fuel, but in petrol engines this means more air is needed to keep the mixture at the best combustion ratio. So if you turbo charge, or supercharge, the bigger injectors will give more power. Otherwise they will decrease power and waste fuel, like running constantly on the choke.

What size injectors should I run?

The right size injector can supply enough fuel under full load conditions at an 80% duty cycle. For example, a naturally aspirated, 300 hp engine (BSFC 0.5), with 8 injectors will need 23.4 lbs./hr. of fuel per injector at an 80% (0.8) duty cycle. (300 X 0.5) ÷ (8 X 0.8) = 23.4 lbs./hr.27.05.2017

Can you upgrade fuel injectors?

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.27.11.2019

Do I need a bigger fuel pump for bigger injectors?

How do I know what size fuel injectors I need?

Can you put bigger 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.23.05.2014

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

Do I need 1000cc injectors?

Do bigger fuel injectors increase horsepower?

First of all, adding larger fuel injectors WILL NOT CREATE EXTRA HORSE POWER! There is a common misconception that the larger the fuel injector, the more power they create. Fuel injectors do not create horsepower, they support horsepower. The larger the flow rate, the more horsepower they are able to support.23.03.2020
