Quick Answer

Question: How many LBS are 1000cc injectors?

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

What does lbs on injectors mean?

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.

How much HP can 1000cc injectors support?

The 1000cc Injectors can support 650+whp.

Do bigger injectors increase power?

Larger throttle body and injectors

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. Go too large and you can lose power.

How many cc are 65lb Injectors?

65lb (650 cc) HEMI Fuel Injectors.

What cc are 80lb Injectors?

Fuel Injectors | Siemens Deka | 80 lb/hr | 875 cc/min | High Impedance | EV1 | 8 Cyl.

What pound injectors do I need?


Can you have too big of injectors?

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.

How do I choose injectors size?

Injector Math: How to Calculate Optimum Fuel Injector Size

  1. Step 1: Determine Horsepower.
  2. Step 2: Determine Approximate BSFC (Brake-Specific Fuel Consumption)
  3. Engine Type BSFC Using Gasoline.
  4. Step 3: Determine Your Safe Duty Cycle.
  5. Step 4: Calculate Your Optimum Injector Size.
  6. Step 5: Fine-Tune the Flow.

How much HP will E85 add?

The benefits of E85 really come from the higher octane (up to 110, depending on ethanol content and quality). This allows some of the same benefits you see when using methanol injection, meaning you can run more spark (if needed) or boost. This normally translates to 25-50 or more horsepower on a forced-induction car.

How much HP can 650cc injectors handle?

So 650cc injector= 650hp if injector is running at 100% duty cycle. I would scale it down a bit to around 80-85% duty, so that would put you at around 520-550hp range. A single walbro can flow enough fuel to feed the car about 500-550hp, but I would advise against it.

How much HP can 550cc support?

So, if you have 550cc injectors, you can see a max of about 367hp which tranlsates into about 275-290hp at the wheels. If you want 350whp, then you are looking at about 435-467hp at the crank. 660cc injectors would be about 430 crank hp or about 350whp.

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).

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.

Do injectors add 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.

What size injectors does a Hellcat have?

Base injector is 38mm. We have adapters for over 300 applications.

How many lb are 850cc injectors?

850cc (94 lbs/hr at OE 58 PSI fuel pressure) FIC Fuel Injector Clinic Injector Set for LS3, LS7, LSA, L76, L92, and L99 engines (High-Z) Previously 770cc.

How much HP will 60lb injectors support?

60′ will support 600+ rwhp with pump fuel…not the case with e85 at those levels!

How many cc are 60lb injectors?

Fuel Injectors | Siemens Deka | 60 lb/hr | 630 cc/min | High Impedance | EV1 | 4 Cyl.

What are multec 2 injectors?

Multec™ 2 is a new generation port fuel injector designed to meet the most stringent worldwide application requirements in passenger cars and trucks. It is suitable for any gasoline-alcohol mixture, on two- or four-valve engines. It is small, facilitating improved spray targeting, packaging, and crash protection.

Which is better high or low impedance injectors?

That low-amp current keeps the injector temperature lower, which makes it more reliable
that’s why the high-impedance design is the most common injector style for OEM applications. Low-impedance injectors, also called peak-and-hold injectors, are sent a more powerful electrical signal, usually around 56 amps, to open.

How much HP can stock 5.3 injectors handle?

At the low end of the 5.3 spectrum, the LM7’s 25 lb fuel injectors are going to max out before they reach the 400 horsepower stage, typically around the 380 horse mark. Gen IV injectors, particularly those on flex fuel models, are at or just above the 30 lb mark, which will bring you closer to 400 horses.

How big of injectors do I need for e85?

Registered. 500cc would be the smallest I’d recommend, and that’s with much higher fuel pressure (&gt
75psi). 650cc would be the min on a stock regulator if your motor isn’t bone-stock, but anything up to 1200cc will work great.

What CC are stock 7.3 injectors?

The 7.3 Powerstroke stock injector is just that, for stock truck performance. They are limited by the total fuel output. OBS injectors are rated at approximately 90cc of flow and they are single shot by design.

What do bigger injector nozzles do?

In short, just remember that the smaller the nozzle, the better the atomization is and the better the ability to tow and keep your exhaust gas temperatures down, while the larger nozzle will make more power when paired with the right size injector.

When should injectors be upgraded?

But once the engine begins to process an increased amount of air (either by adding boost or NOS or grossly changing the engine’s displacement), the fuel injectors won’t be able to flow enough fuel to keep the engine from running lean. This is when one should consider upgrading their fuel delivery system.

Are all injectors compatible?

If the body of your car’s injectors is gray, keep in mind: injectors of all releases ARE compatible! So, your car can have injectors with a different release for each cylinder!
