different injectors

[gmail]

just wanted to see if anyone has ever messed around with multihole injectors..

for example what i mean if on the jeep 4.0 they come stock with single hole injectors and its a upgrade to go with the 4 hole ones for better fuel atomization, actually a few ponys can be had this way.

the SHO i know has 2 hole is it kind of jets one to each primary and secondary.
i figured with a 4 hole it would just kinda work as 2 for each.

im sure i could give it a try myself and go from there but i was hoping someone made this attempt and has some info for me...

thanks

I dont see this making any gains on a stock engine. On boosted engines maybe but as far as I know most modern injectors flow pretty well even with 2 holes and some have more. As long as they are clean and the pindle cap spray nozzle is "clocked" correctly .

Check out shonuts website. He touches on this subject this with the new accel injectors he sells. Much better spray pattern, I can't remember if the accel are 2 or 4 hole though. I would find the link but I'm on my phone. Actually there might be a thread on shoforum too, there was a GB for them Iirc

It would only be a tip thing cause when you remove that yellow tip , theres only one ''outlet''.

I have the 36lb accels and IIRC they're 3 holes, but I could be complety off. They're in my car now and I forget what they were but my guess is 3.

i didnt check his site i didnt find it and i wasent real sure where to look... shonut that is.


also i did a search on this forum a couple times but i didnt find anything i will check around the group buys here shortly... thanks

The disk-style Accel injectors have 3 holes.

Josh made a thread a few years back on it. Search for "injectors" from his screen name and you'll probably find the thread.

thanks a ton, i didnt think to search his post like a idiot..

i am really amazed how bad the stock injectors are... im sure a stock SHO would pick up a few hp from changing to better injectors..
im gonna do some looking around im sure i can find a car that uses the proper ones like something out of a junkyard...

from what i got so far the ford #24 lbs are the ones the jeep guys use on their strokers with raised fuel pressure and they fit well.also they are the 4 holes. i already know jeep and SHO injectors are same dimensions..

the #24 are in the 4.6 engine and they also have the same plug as the jeep which is the same as SHO also..

im gonna have to grab a few more at my next boneyard trip and give them a shot...

even if it helps idle its worth it, but on the jeeps the 4 hole injector upgrade gives better throttle response, power, mpg and idle is smoother and i know this already since i did it on my 4.0...

top 2 pics are stock and the bottom 2 are the 3 hole accel injectors he sells

**** i am shocked how bad the stoke injectors act since the pictures josh has posted make it look like the stock injectors just shoot in the ports like water guns. we already know the better the fuel mixes with air the more power is made.


0280155715 is the injector part number that should work fine..they are 25.71 lb/hr at 43.5 psi and im certain the stock computer could make up for the difference
i would suspect that these injectors would be good for 310/315 hp at 100% duty cycle in a stock setup... raise the pressure some like 55 psi or so and i would bet 350 hp could be had out of them...
now if you were gonna go boosted i would recommend bigger injectors i doubt these can handle much more then 55/60 psi



actually found a list of where they can be located in a junkyard i will post

One of the reasons why I went with the Accel injectors, was the fact that they should be a better unit than the ford ones.

may i ask why you are running #48 ? do you plan to run some boost in the future?

yeah if hes making like 500 hp then ok, but 36 or 37 lbs would be ideal... dont really matter tho it will run no matter what size plus that leaves room for n2o and such with bigger injectors and to be honest i would only buy injectors once if i were to buy new ones

 

[Ishodu]

I went with the 48s because I need more fuel and I would have the room to play with injector timing. I may also make a nice NO2 tune someday where I can purely use injector to supply the fuel. FYI I have gotten the 48s up to just shy of the 50% DC at 12.5:1.

im impressed that thing must be running good.. you got it fully broke in yet for some WOT runs?

 

[Ishodu]

I am currently working on a few other items, It appears that I am reaching a point where either my current intake can't flow enough air or I have reached the limit on the cams. I figured the cams would flow more higher but this is not the case. I will see when I put my very ported intake on with bored out TB and such if there is a diff. There is around 1200 miles on the engine before I stored it away. And I won't get to play with it until april or May. Then I plan on getting this stuff on and maybe get some time to tune it and just see what it does on the dyno.

if your running a stock intake then for sure its the intake...

from what i remember the +40 cams are .293 lift? these heads flow the best at around .450 lift was what the one guy had got from flow bench testings. so im sure the +40s will hit a limit somewhere but i would assume that would be probley before 9k.

the intake is the limit. in stock form it starts falling off at 6500 with the stage 2 or +40s it pulls upward of 8k with intake work..

i recommend either acid porting or running it threw extrude hone 10 times since it removes so little.
a extrude hone removes like 1/10th a inch but it makes the walls so smooth it aids in the speed the air travels to the engine.

with a 12.5 engine id say acid porting would be almost a must for that thing to breath
imo anyways.

really no one on here goes to get things flow benched to know all this stuff for sure.

 

[Ishodu]

I will have to compare the fluid volume of one of my newly ported runners to that of a stock unit. I would estimate around 20% more at least on the short runner as I was able to bore that whole runner. I may look into someway of doing the whole long runner but this may not be as important and may help keep from loosing some low end tq anyway.

 

[rubydist]

the torque peak is more related to the length of the runner, not the diameter.

Great Thread.

Although barely related, I know the BMW guys that run the twincam 4-cylinder motors like upgrading to Mustang injectors because they have four pintles (?) and atomize the fuel more effectively.

I'm happy to find some details if anyone would find it useful.

if you want im sure someone might find it useful..

as for me im just gonna grab 96+ tauri injectors my next run to the junkyard i also gotta grab a pile of things while im there so im planning a run soon and ill end up installing these injectors this summer and see how well they are for n/a.. after a ultrasonic bath
