This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause.
The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it.
I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary.
In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at.
This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.

Leak down testing
I get a lot of questions via email and over at the forum about the steps to
take when you encounter a performance issue like my Subaru's hesitation
issue and I often feel like I sound like a broken record when I cover the
basic steps that I cover when encountering a situation like that. My main
point here is that if you have a performance problem and you're going to
throw parts at the problem start with the basics before you to off and
start replacing sensors that you suspect are a problem, if you don't have
evidence of a faulty sensor then don't start there start with the simple
tune up items and check for vacuum leaks and air leaks as I've shown here
and I believe you'll have better results and save yourself some money in
the process. In short the rule of KISS applies, Keep It Simple Stupid.
If you have questions about your own engine performance issues head over to
my website and either ask the search function or ask the forum, we'd be
happy to help.

Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra
small-combustion-chamber head. Thats what it is. It's a J1 engine's
In Cylinder Head 106 I talked about the mainstream porting theories as they
are discussed. We looked at a cylinder head that I have thousands of
dollars of professional work performed on, and a bone-stock
second-generation head that I didn't port.
In this video I just might do something you haven't seen done before. For
some, that may be uncomfortable. The port and polish job I perform here is
what I think will work best for my current build. This is not an extreme
killer port job. What will be different here is where port textures are
concerned, I will be following the advice of a reputable source that will
remain un-named. You're free to port yours differently than I do in this
video, and I give you that out, around the 20 minute marker.
The Hyundai is far from being an ultimate-performance build. It's a $400
box of scraps with nothing but time invested. It's perfect for this video.
My finished product WILL be an improvement over what I had. I don't yet
have access to a flow bench. I still have an achievement to un-lock. As
far as you should be concerned with the techniques I employ... without flow
numbers there is no evidence of what this will do, but we will gather lots
of info from dynp sessions and drag strip time slips. If I could test it on
a flow bench, I would.
There are MANY, and when I say many, I mean thousands of flame war
mongering pirates floating around on rough seas with a hair trigger cannon
finger itching to fire if you port a head any differently than what the
herd mentality says to do while porting a cylinder head. I cover the herd
mentality because it has merit. It's been tested. Tried and true. But I
don't follow it to the letter of the law. I'm definitely not here to
de-bunk it. I would port a cylinder head differently for each build based
on how that engine was used. There's an extremely valid reason why
relating to air speed. It's not the texture of a port that maximizes the
effect of fuel atomization, but the velocity of the air running through an
x or y sized valve. The driving factor in this is the piston speed. I'm
not going to give you the technical information, but will refer you to
information about the Lovell factor. There's a better description of this
in the links below, and even a calculator to help you find your engine's
Why the Lovell factor is important:
Lovell gas factor calculator:
Only people who have flow testing equipment know for sure what really works
and have the capability to produce a perfectly-matched port job for the
ultimate performance build. Those guys know the definition of ultimate,
and THEY are floating below the water Aegis-class submarines ready to blow
your comment up if you don't know what you're talking about. They don't
care if you're an armchair mechanic or a herd of pirates. I will say,
they're zoomed in pretty close on me right now, and I'm expecting to take a
few hits. My work will be tested based on Dyno and drag strip performance,
and the results will be posted here. Fortunately, those kinds of videos
are a WHOLE LOT EASIER TO MAKE!!!
DIY Testing & build EFI Fuel Injector cleaner
In this video I detail some quick tests and some not-so-quick fixes.
A dirty or stuck injector is not usually a fatal problem for the part. You
can clean injectors yourself with a little ingenuity, or use an injector
cleaning service. With the method I'm using, you won't get a sheet that
measures how much fluid is flowing, but if you use the right solvent you
can at least remove whatever is blocking it so that it can flow like it did
when it was new.
So the journey begins.
Homemade Fuel Injector Cleaner - How To
There has been a follow up to this video and it is located here.
This project was inspired by another Youtube member.
I picked up a set of used Blue Max 1650's and wanted to clean them before
I followed the video in the link with minor adjustments. When using
the larger coupler listed in the video, I could not even get the threads to
drill out. I had a smaller coupler laying in the garage that worked for my
injectors. I also used the drill bit one step above the 27/64 listed in the
link. This is 7/16 and just seem to be easier to handle while maintaining a
Another discovery along the way is the size O-rings that you could use
for upper seals. If your injectors have good seals, Why chance ripping
them. A #11 O-ring serves for a great base O-ring on the top side of the
injector. The #78 serves for an outstanding upper O-ring for the upper
seals. You will see this demonstrated in the cleaning video.
One last VERY IMPORTANT note is YOU MUST USE A AA BATTERY FOR THE
SWITCH. I started out using a AAA and had great results on the 950's but
the AAA would not open the 1650's under pressure. After adding a AA
everything worked perfect.
The injectors did measure out to be 2.3 ohms.

Learn to test and analyze automotive fuel injector circuits from a wiring

very time consuming to detect and prove a clogged fuel injector. The
technician needs to disassemble the fuel rail, de-activate the fuel pump
and perform lengthy tests to prove the fault. However, there is another
way. Using current ramping techniques the technician is able to prove the
fuel injector without any disassembly at all. Get the scoop here and save

After assembling the Fuel Injector Cleaner in this video
http://www.youtube.com/watch?v=zlO4krw2h8o I noticed these problems and
they had to be addressed. Smaller injectors worked fine with the single AAA
battery, but when I tried the 1650's they would not. This video shows a
solution to that problem and how to get larger injectors to operate on the
Also included in this video is O-ring sizes for upper injector seals. I did
not want to ruin the injector seals that I planed on using in the car, so I
got the O-ring box out and found a set that fit the bill. I share their
