It's pretty cool that hot rodding is really starting to come full circle where various creative uses of stock parts are really a very viable way to go.
awesome to see some actual hard evidence of the changes thanks for the update, keep up the hard work
this is some awesome info. great job to both of y'all! thank you!
Thank you for saving me some money👍, awesome info and content!
Great overview of the cycling of decamped injectors
Getting ready to start my build finally.. I haven't seen the mighty car mods decap videos but I can bet they give a slap stick, off the cuff ozzy slang filled description ( not bashing them just saying I have cash wrapped up in this!!!).. You explain things and are still hilarious (imho). I never used to comment because I was concerned about sounding stupid but you don't know me so I can sound like an idiot without daily shame! Thanks for the videos my friend!
I really like your process and methodology, breaking down step by step and explaining as you go. It is good for people to see, hear and understand what happens in the world of injectors and you did it well. As mentioned in the video, the pencil pray pattern will run and perform. If delivering more fuel for your build is what you want, then this this is your ticket. However, just dumping more fuel without adding air is counter intuitive to making more power. Atomizing the fuel will always give you a cleaner and a more complete combustion, thus creating more horse power. In a N/A setup, a straight stream of fuel will burn and make power but, will run into more carbon fouling and less power than a atomized pattern. If you rough up the intake runner after the injection port before the valve, it would help atomize the fuel with a straight stream of fuel. With a power added (forced induction) the pressures and velocity can and does break up the straight stream more than N/A. But as I mentioned before, when the fuel molecules are smaller (atomized) vs straight stream (droplet) regardless of the engine, it becomes more efficient, cleaner, complete and creates more power.
Very cool thanks for sharing this info Matt
Very cool and tons of good info
Impressive results.
awesome stuff man!
haha I bet you double his business with the video.
Thanks for answering my concerns
great info man
So I just did this and I found if you use a bench grinder and a 13 mm wrench and put the injector threw the box end of a wrench it's really easy to spin the injector and hold it at the angle you want to grind off the cap
Just goes to show them import guys know what's up ! Great information!! Good to see real world testing results .
going down the path of trying to decap injectors however my injectors for aussie Barra 6 cyl turbo motors, just to give it a go my problem is that my injectors are just like those ones you have that are recessed. probably going to try a 6mm end mill from a lathe will post some pics if it works on sloppy page...good stuff on the video mate inspiring aussies to help the kids in Australia because they need burnout smoke to survive
Thanks fore sharing :)
gave me chills when they went full blast
Thumbs up!
:clickbate article: INJECTOR COMPANIES HATE HIM! CLICK HERE AND SEE WHY
lmfao I can see it on speed society in the near future..
so was he able to provide you with all the data needed to tune as well?
The "shorter" 6.0 injector that flows 51lbs, is a Gen4 e85 injector? And are those easily swapped into an 03-06 5.3 with stock truck intake & rails? Connector adapters and height adapters?
So do you still use the stock injector data, but modify the flow rate?
this is awesome. hopefully will save you and me some money like lol
What injector timing information would you use for uncapped injectors?
The factory injector you referenced as 70 pounds or so, (12613412 part number) is for a gen 4 6.0 as you stated you thought. My question is can I put them in place of my stock gen 3 4.8/5.3 injectors on my 4.8 or will I need different fuel rails? I don’t mind the re-wiring part.
great info Matt. Hey are you ever going to do an episode 5 of sloppy seconds?
Yep with mark at urban racecars will be the next one I will make a video roughly a week before pre-gaming and asking for questions
This may be a stupid question or maybe I just didn't hear you but did he replace the filters?
three things. first, 13:48... not quite
my tempo. second, I hope Eric survived the bowling green massacre. third, very cool video.
With the difference they flow, would you be worried about chucking them back in? looking at doing this myself
did he just remove the filters or put new ones in? and if now there's no filters did they affect flow at all?
I have a ford 4.6 I've never take out injectors and looked at them. Will this work on them?
WHAT OTHER FUEL UPGRADES ARE NEEDED. FUEL PUMP, FUEL REGULATOR ETC FOR BOOST. OR DID YOU NEED AN HP TUNER ETC? PLEASE LMK
Could you take a sewing needle and just put 2 or 4 more holes in the cap and get the higher flow rate?
have you install those 70lbs injectors yea?
Would there be any advantages to looking for 8.1 injectors?
I know this is an older video, but what test fluid does he use and is it 1:1 equal to gasoline? Some use different fluids and 55# of test fluid may not equal 55# of gasoline.
You know the price to have this done?
how much does it cost to get them flowed and test?
Speaking of the sloppy public page, i've tried to join a few times but I get rejected each time. Am i not allowed to join?
Did you actually end up using these In a car?
Awesome I was wondering how close they were after decapping.. would you want to put the higher flow one on the cylinders that usually lack fuel (#7) or would want to send 2 sets and match them up better
You could yes or like I said in the video ship 20 injectors to him and have him Match a closest set
+Sloppy Mechanics awesome videos man keep it up the sloppy wiki is my homepage
Richard holdener jr with the hand motions
what if i decap l59 injectors?
now with this would you still use the factory injector data or would you have to modify that by trial and error?
correct, you would just modify the fuel tables, injector size, or other fuel figures till it runs and starts normally with trims close and tune from there
do ya think the 80 lb injector tune would start and idle with these injectors?
correct, i believe it would be very close
I think I'm going to have to do this on my neons so I stop melting pistons...
I'll give you some info on my truck the 92 Chevy 1500 2 wheel 2001 5.3 th400 trans with shift kit 2500 stall motor and trans are brand-new have completely rebuilt the motor we put a hundred miles on it
did the injectors get less consistent flows before and after the decapping? 4% doesn't sound too good. 2% less than 12.7AFR gives 12.95 which would start getting dangerous if you're pushing for peak power.
imagine if you got a pile of them and sent them all in and he matched a set for you within 1%
Found a good deal on genuine "new" gm e85 injectors on ebay ....$74 for whole set .....
still only approximately 42-50lbs
7% variance? That would be nearly a FULL AFR POINT between the high and low cylinders. Not to mention the bent spray pattern for the three on the right.
Hydrocarbon82 good point.. and this is what a pattern should look like... ua-cam.com/video/YtlPOs-qbRw/v-deo.html
He did clearly state that for boosted engines the pencil pattern is more desirable since it directs the fuel stream into the intake valve which is where you want it. The unstable airflow from the turbo in the intake actually will cause problems with fuel delivery to the intake valves. That is mt understanding of what he said. Lack of fuel in a boosted engine is a big concern. Better to get it to the intake valve as efficiently as you can i would think.
What kind of liquid do they use when testing?
i have no idea, maybe i will email eric and ask
I think they use heptane because it has the same specific gravity as gasoline.... maybe lol
Did nobody check out my video yet it is a good link if you are interested and the answer is in there somewhere I am not just going to rewatch the whole thing to find out tough.
how do i reach Eric???
Supposedly atomized fuel being in the air charge longer reduces knock due to a cooling affect. Other than that there should be no difference.
What are the stock 4 hole injectors out of. I think they flowed around 50?
i believe flex fuel vehicles like 02 tahoe, they are like 38-42lb IIRC
I know for a fact that a 2010 chevy uses the flex fuel injector with the 4 hole .....
I have a 2010 chevy express with a 6.0 that is a flex fuel vehicle
My stock 99 5.3 lm7 have 4 hole.
I have a part number 25317628. I believe they are 22lb fuel injectors..if I do exactly what you did..what results do you think I get?just and idea
branden at www.lt1swap.com puts these at 25 lbs/hr

What do you recommend for a good but not insanely priced ecu ( something decently cheap )
I want to get one but there really isn't much information out there easy to access and I don't have all day to go through forums and stuff
spareecm on ebay, abt $90 you provide your VIN, or they can provide one for the year/model/engine you want
Why do you imply that gen 3s don't survive well above 550?
the rods are not as strong and frequently people hurt them when pushing them, it can be done, but if your goals are higher its usually a good idea to start with the better rodded motor to start
Sloppy Mechanics can I slap gen 4 rods and pistons in and expect a higher ceiling?
so from 25 lbs after tha job it came up to 70 lbs?
your summary is correct
+Sloppy Mechanics fucking awesome
+chihuahua8209 I'm trying to do the 2 hoe injectors I believe they are 22 lbs stock 6.0 ls if I do the same job do you think they will do 3lbs less?
what does something like that cost to have done?
I would like to know as well. thank you for the video
i paid 70$
+Sloppy Mechanics ok sweet cause i have set of truck injectors that came with a truck intake i bought. im totally going to uncap them and send them to eric
he charges 75 bucks per 8 injectors. I just had 16 done by him and he is great to deal with, I would highly recommend going through him.
I just emailed him. Does he descreen all injectors, or simply old ones? Debating on whether I should send him my decapped LS1 injectors with 126,000 miles, or just send him new ones.
How much $
Ball park#
Quickly googled and found this..
www.gmpartsdirect.com/oe-gm/12613412
Seems to be on 6.0's flex fuel motors, some diesels, basically most stuff in the GM 2500 series or higher.
here is a johnny come lately comment: that is a 2010+ Flex Fuel injector. I bought 8 of those myself sep 2016 (for $60), needed $20 connector adapter and installed July 2017 in my 5.3 and adjusted the tune for 50 lbs. They have been running great since then. Now I am going to try my original 25 lbs and decap them as per this vid to see what they will do. Matt, you have great info in these videos. Thanks
same length, they dropped in just fine. Added the connector adapter, screwed down the rail (no spacers/not tight), then reflashed the ECM with HPTuners with the new 50 lb/hr
value. Working great.
www.lt1swap.com/identify_vortec_engine.htm is where I learned about them and other injectors, from Brendan's work
we never heard nothing back about you putting these two characters and your wife's truck you're not seen the video and how much power it makes I am extremely interested on some info I have a 5.3 you with the trick flow 585 cam is that you're using I'm getting ready to put a Garrett 76 mill on my truck I would like to know what power you made with that came before it go in your father and have to change it
i did upload a video with my wifes truck, it made 350whp with 4lbs of boost, we are leaving it go right there for a long time most likely since 60e's are not known for handling a ton of power.
Sloppy Mechanics I need your advice if you don't mind I want to do your decap injectors I'm running a 76 Mill turbo intercooler anything else you can tell me I need to run on my motor I have a walbro 255 fuel pump do I need to go bigger than that I already have a 2 bar map sensor if you could just give me some advice on what direction to go I greatly appreciate it I've been watching your videos for a long time now I would not be where I'm at with my LS truck without all your videos in the info
I don't know if you want to talk through email I don't want to clutter up your bored here on UA-cam I have a couple more questions
I can hear all the injector salesman now (Thanks alot Sloppy) 😠
