Can you give me a 101 on injectors

so ive never really looked into injectors before,
i was wondering about what to look for what all the numbers mean like 160cc/30% exactly means what are some good injectors and ones to stay away from and how hard are they to put in?

but this would be a maybe after i get back from my deployment cuz my room is starting to look like a little supply store with parts ive been getting to put on my truck when i get back, ive just been curious about them

what do you guys think my HP and Torq numbers would be with my new parts that ive already ordered , and then after the injectors?

right now its got
Banks big hoss chip
Spectrum Cold Air
Banks Monster Exhaust kit
HD rebuilt tranny with 6 stud torq conv. & bigger cooler and electric fan

this is what ive ordered so far performance wise (parts not installed yet)
TS Performance 6 pos. Chip
S&B Cold Air
muffler "delete" kit
front and rear AFE diff covers
Triple gauge pod (im waiting on buy gauges tell i now what colors to get)
AFE 6" exhaust tip
BD Power Billet Wheel
BD Power Adjustable wastegate

THANKS!

now anywhere from 310-330 id say, at the wheels.

how much hp are you looking for?
if you want to stay around 400. go with 160/0, 160/30, or 160/80 injectors

Did you get that ts chip set for the 160/30's or stock injectors? If you upsize your injectors you have to reflash your chip.

I like php personally, tw and a few other tuners can set your chip up with their tuning. Although some injector companies also offer tuning with the injectors.

You can get your ts chip reflashed by a custom tuner for future reference, bit cheaper then a new unit for no reason.

the company that was offering free tuning with injectors is no longer offering that.
i like my php but they are slow. ive heard that gearhead is pretty quick.

Larger nozzles- By installing larger nozzles you are makeing the nozzles less restrictive so that more fuel will flow out of them with everything else being the same. Stock injectors with stock programming and larger nozzles will get more fuel out and make more power. Stock injectors only modified to have more fuel capacity with stock nozzles and stock programing will run exactly like stock injectors. In this case the only way to get more fuel out is with a chip to extend the open time of the injector and/or increase the Injection Control Pressure (ICP) to push more fuel out the nozzle. On the same note if you say make a hybrid (installing a larger 7mm plunger and barrel out of a DT466/I530E injector) and leaving the intensifier piston the same will effectively reduce your injection pressure. This less injection pressure will make less pressure at the nozzle and will actually flow less fuel with a stock nozzle than a bone stock injector. So to get the fuel out without a chip you would need larger nozzles.

There is also a point where the stock nozzle just wont flow enough fuel to get the desired amount out in a realisitic time frame. That's why high capacity injectors require larger nozzles to use that capacity.

Codes- All powerstroke and T444Es come with A code injectors. A code injectors have a 6.0mm plunger and a 16mm intensifier piston. What this does is multiply the ICP so that injection pressure is adiquate but not having to have huge amounts of ICP like say in the 20,000 psi range. This difference give you approximately a 7:1 difference and therefore increases your injection pressure 7 psi for every 1 psi of ICP.

All DT466s and I530E injectors are B codes. Of those some DT466s and all I530Es have a 7.1mm plunger, hense more fuel per mm of stroke, with a 17.5mm intensifier piston. This gives you approximately a 6:1 ratio. So no it will not have quite as high of ICP as as the A codes but it's not as bad as it could be. However due to the larger intensifier piston they reqire much more high pressure oil to make the piston stroke the same distance. This is why you need a high pressure oil system with a higher capacity.

Hybrid injectors are taking the 7.1mm plunger and barrel out of a BD code I530E injector and installing it into an A code injector with a 16mm intensifier piston. As you could imagine the down fall is that the injection ratio is dropped to approximatly 5:1 further decreasing injection pressure. However with the smaller intensifier piston it requires no more oil than an equivilant A code yet it flows the same amount of fuel as a B code. The result is much more fuel capacity without the need for more high pressure oil volume.

A codes and B codes can be further broken down as well.

A and AA injectors came in the '94-'97 non-california trucks. They are all 90cc injectors and are single shots.

AB injectors came in the '97 cali, and all early '99 trucks. They are split shot injectors meaning they fire a small pilot shot before the main shot. These injectors flow 130-135cc of fuel.

AC injectors are found in the high torque version of the T444E and do not come in any Powerstrokes. They have the same internals as the AB injectors with the exception of the single shot plunger and barrel. However due to them being single shot injectors they flow 160cc. This is due to the way the split shots work. They have a small passage that opens, much like a port in a two stroke engine, that are uncovered that bypass the injection pressure out the side of the barrel instead of out the end through the nozzle. Because of this pause a portion of the travel of the plunger does nothing for injecting fuel so a split shot injects less fuel for the same amount of travel as a single shot.

AD injectors are also split shot but flow 135-140cc of fuel due to a slightly longer plunger stroke. These are found in all late '99-'03 Powerstrokes and T444Es.

AE and AF injectors are essentially the same as AD injectors but were called a long lead injector that was used as an attempt to cure a "cackle" issue many people complained about.

BA, BB, and BC injectors are essentiall all the same and are the same as AC injectors but are found in some DT466s.

BD injectors are the only B codes with the larger 7.1mm plunger and barrel that are single shot injectors. These are the injectors people are usually talking about when they are talking about putting I530E injectors in their Powerstrokes.

BE injectors are essentially the same as the AD injectors but found in some '97-'99 DT466s.

EF, BG, BI, BJ, BN and BP injectors all have basicly the same capacity and are split shots. However the nozzles vary on them depending on application. They can be found in many DT466s and I530Es.
Here is some good info...
