Injector Data Compilation

Aug 15, 1. I figured since everyone usually up's their injectors, this would be good. Configureing your BSFC: When you want to upgrade injectors, you will need to know how much fuel you will need to supply the amount of horsepower you have or are shooting for. The BSFC is how many pounds of fuel it takes to make 1hp for 1 hour. The BSFC is usually around 0. An injector that flows Sometimes, You may not find an injector that exactly matches what you need.

By changing the pressure, you change the flow rate. It is better to do this when the injectors are just a little too small, than to go to larger injectors. The chart below will show what can be done by adjusting fuel pressure. You can see from the chart that there are quite a few options to get very close to what you'll need. Rated Flow Fuel Pressure These mods will usually run closer to a 0.

Saturated injectors are more common and draw less amperage form the ECU. Saturated injectors also create less heat because the have less amperage.

A saturated injector will have an impedance of about 12 ohms, this means that at 12 volts it take 1 amp to hold the injector open. Peak and hold injectors will have an impedance closer to 2 ohms and draw about 6 amps. Most ECM's cannot handle the amperage and using peak and hold injectors will harm the them. If you desire peak and hold injectors a separate aftermarket injector controller or aftermarket ECM may be required.

Peak and hold injectors use high current to open the injector very quickly and precisely, then they draw less to hold the injector open.

For high horsepower and flow rates, the peak and hold injectors are much more precise, but they are more venerable because of the heat they make. If it is a street engine that will be daily driven, saturated injectors are more reliable for long term use. Peak and hold are better for high horse power and competition use.

Just about the time we get comfortable with a certain injector, a new version debuts and we have to learn a new set of parameters. However, for performance engine builders, EFI swappers, and inveterate engine tinkerers, this ever-expanding range of fuel injectors offers both opportunity and confusion.

Or, you could just listen to your brother-in-law — he knows everything, right? This story will take an overview approach to GM fuel injectors. We will focus on all the important injector fitment specs such as overall length, O-ring sizes, and electrical connectors. The connector part of this story would not be too bad if the industry could stick to one name — but with multiple names for each connector — it can get perplexing.

This injector family portrait includes four of the five popular GM fuel injectors. The one missing version is the late truck injector that is the same height as the early truck LS piece but using the EV6 electrical connector.

What you will notice is a lack of flow rate information — since this would add a cumbersome volume of material to this story. Combined with the accompanying images, the chart is probably the easiest way to differentiate and make sense of all the different GM injectors. All cathedral port LS engines use the same injector spacing which allows using aftermarket fuel rails like this Holley.

Aeromotive does not recommend mixing and matching fuel rails due to the possibility of a high-pressure fuel leak. These injectors are physically the largest and tallest of all the GM injectors. These Bosch injectors used a connector that is referred to by no less than three different aliases.

The earliest reference is the Jetronic —the Bosch name for its early fuel injection system. This connector evolved into the Minitimer that now morphed to EV1. Right away, this becomes mystifying with three different ways to describe this electrical connector. This injector was used all the way up into the mid model-year in certain vehicles. Next in line in terms of height is the first-generation LS1 injector. This unit is much slimmer and slightly shorter than the early Bosch injectors, taking up much less real estate.

The early Gen III truck engines such as the 4. Making this early truck injector unique is its Multec 2 connector. Since most aftermarket EFI systems target the more modern EV6 injectors, using the early truck injectors will often require an electrical adapter.

This is the only injector that uses this electrical connector. Somewhere around the model year, the truck injectors changed again. This truck injector is 0. This is the shortest injector of all the factory squirters, but its size should not be confused with a lack of flow potential as these injectors can crank out the fuel.

Left Wiring pigtail adapters allow you to use existing injectors with a different harness. While this might work as a temporary fix, even the smallest amount of resistance in the circuit can affect injector performance. Swapping these newer, shorter injectors, in taller intake manifold applications opens up the opportunity for aluminum extension fittings that can increase the injector length to adapt these injectors to earlier applications.

For example, ICT Billet offers three different length adapters for specific applications. Another subtle change that occurred with the Gen IV LS3 style injector is the lower O-ring diameter which increased from 0. These larger O-rings are sometimes distinguished by color. The AC Delco versions are blue for the 0. The newest LS3 fuel injector uses a larger diameter lower O-ring compared to all the previous injectors.

The difference is 0. If you are adding an earlier injector to a later intake like an LS2 or LS3, you will need the larger diameter 0.It would be nice if every new cell phone and electronic device was equipped with the same charge cord. The same can be said for electronic fuel injectors. Just about the time we get comfortable with a certain injector, a new version debuts and we have to learn a new set of parameters.

Another subtle change that occurred with the Gen IV LS3 style injector is the lower O-ring diameter which increased from 0. These larger O-rings are sometimes distinguished by color.The power ratings discussed above are for each injector. This means that you need to multiply this rating by the number of injectors that are to be used. So, if you were using the Impulse RS cc injectors in a 4 cylinder engine with one injector per cylinder the max power that the injectors could deliver fuel for would be about Conversions cc per minute is approximately equal to 49lbs per hour which is equal to approximately hp.

This is the most common type and still the best. A tapered needle sits on a tapered seat. When the solenoid is energized, the core and needle is pulled back, allowing the fuel to discharge. This design has been well proven for over 30 years.

The Bosch disc type uses the same type of actuation mechanism as the pintle type but replaces the pintle with a flat disc and a plate with tiny holes. These work fine with a good spray pattern but are slightly more prone to deposits plugging the holes.

The Lucas type buries the disc up inside the body to reduce the mass of the assembly for quicker response. The Lucas types typically have a very narrow spray pattern which can affect idle and throttle response in some cases.

These use a ball and socket arrangement. These have excellent atomization and a wide spray pattern but are also prone to partial plugging by varnish deposits. For the majority of injectors, there are two types of electrical connections. The D-Jetronic type used from to or so on Bosch injectors in which the plug fits internally into the injector and the L-Jetronic type in which the plug fits over the injector offreing a waterproof seal.

Most injectors of all brands built after use the later type. Unfortunately, several Japanese manufactuers, notably Subaru and Toyota decided to make their own style connectors in the late '80s. These use an oval shaped plug. The D-Jet type will fit most types but is not waterproof. Fuel transfer from the fuel rails was done with barb fittings and hose on early injectors as shown on the left above or small or large O-rings as shown above on the right.

The later type uses a rigid fuel rail to hold the injectors down to the manifold as well as seal to the O-rings. Sealing injectors to the intake manifold usually involves one of two methods. Older type injectors used a square section O-ring slid over the pintle cap to sit against the steel injector body. Newer injectors use a 14mm round section O-ring sitting in an isolated groove.

These are not compatible with other types. Most OE injectors are quite small because stock power outputs are usually quite low on production engines and metering is more precise with small injectors for better idle and emissions. For performance applications, engines often require much larger injectors to satisfy the increase in fuel flow.

Often larger OE injectors can be fitted from a different engine. Sometimes aftermarket ones must be used. MSD makes 50, 72 and 96 lb. It is essential that you have injectors large enough to feed your engine at maximum power. Most OE systems maintain a fuel pressure of between 36 and Fuel pressure can be raised to increase the rate of fuel flow but this should not exceed 60 psi in most cases. It takes 4 times the fuel pressure to double fuel flow.

Raising the pressure to extreme levels is very hard on the pump and can lead to leaks or failures in the plumbing and injectors themselves. Use the proper flow rate for the intended application.

If you plan to fit used injectors to a performance engine, always have them flow and leak tested first.Activity Feed DSMtuners. Join the Community!

These may not match exactly with the values you've seen elsewhere, but they should be fairly close. The problem is that each injector can behave a little differently from another of the same size and manufacturer.

So there's some variation that simply can't be accounted for in all cases. Start with the values listed below and fine tune from there. All of these values assume stock base fuel pressure 37psi for 1Gs and Deadtime is listed as an adjustment to be entered into the ECMLink application, which is then applied on top of the calculated stock adjustment. For more details on how to adjust for varying fuel pressure or how to use the fuel adjustment tab in ECMLink, see the Fuel Settings page.
