What size are stock SRT-4 injectors?

750cc
750cc injectors are pretty big for a stock turbo car. 750cc injectors at the SRT4 58 psi will allow for a maximum of about 400-425 wheel hp.

What do higher cc 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.

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

How do I know what size injector to get?

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.

Are bigger fuel injectors worth it?

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.

Are bigger injectors worth it?

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.

Are bigger injectors better?

Bigger is not always better 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.

Does injectors increase performance?

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 (as long as it’s matched with enough air).

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.
