- In Episode 196 of Mike Finnegan's Garage, we visit Harrell Engine and Dyno and Customs By Bigun in Mooresville, North Carolina. At HED, we check out the broken Hemi that powered Blasphemi, my 1955 Chevrolet Bel Air, to the A/GAS Class win at Hot Rod Drag Week 2019. We also get a good look at the replacement parts Pete Harrell is going to use to upgrade the powerplant. These parts include a new cast aluminum engine block from Keith Black Racing Engines: keithblack.com/
Forged pistons and connecting rods from CP-Carrillo: www.cp-carrill...
Total Seal piston rings: www.totalseal....
and a Callies crankshaft: www.callies.com/
We'll be re-using the same Stage V cast aluminum Hemi Heads: www.stagev.com/
and The Blower Shop 8-71 high-helix roots supercharger: theblowershop....
After visiting Pete we walked next door to Customs By Bigun to see what hot rods they were working on and to have the Holley fuel injectors taken from Blasphemi and Game Over, my twin-turbo 711ci Hemi-powered jet boat, flow-tested. The results were surprising:
The injectors were 120 and 160 lb/hr flow-matched units from Holley: www.holley.com...

I’ve learned more about injectors than I ever thought I would know in my life. That was awesome, thanks 👍
I slept through half the video and still learned something XD
Same 👍
Same
right? probably the best and most practical video example of injectors i've ever seen.
Ditto
Theres a look Eric’s face, 10 seconds before he exclaims that the injectors are different. It’s priceless. He started to smile when he realized it and just wanted to make sure.
Good catch! Right around 54:20 you can see the lightbulb go on.
And Mike's face after that. Turned super red!
This is one of the most educational videos you have produced Mike, thanks !
literally i think he learned a lot too. like the difference between 120 and 160 lmao
@@finck9226 and the difference between first and second and why not to helicoil the head stud holes on a supercharged engine
@@davidwoermansr lmao all kinds of lessons were learnt that day
@@finck9226it was definitely an educational trip

Hey Mike. Hardcore roadkill fan. Hoping to be able to meet you someday, been watching since season 1 of Roadkill. Which I was still just a kid. I actually got an Automotive degree a few years ago because of your influence. I appreciate everything you’d done
It's so cool to hear that these guys have had so much positive influence on the younger generation. Hope you love what you do, man.
Just remember the difference between men and boys is the price of their toys stay young and have fun with whatever you do if you can find a job that you enjoy and have fun everyday you'll never work a day in your life and also get paid to have fun
Hey guys me to I always wrenching with my dad in the yard got pics of me sitting on the fender of one of my dad's old cars as a small boy maybe 6 or 7 .then start building when I was 14 did my first car a ss 396 when I was 15 got it done when I was 18 .then the race cars came in lol .got married and the kids came and the CARS fell off I got back into it in 05 and me and my day got a 67 firebird rag top and we started on that it was our project and in 06 I lost my dad so I couldn't even look at it and sold it....but now iam getting ready to retire in 2 years so got a old vette a year ago and iam into that .and got a lift for the shop and getting set up to start at it hard .thinking about get a old shoe box nova and put it on the track put a nice stroker in it on the bottle and name it after my dad he always loved when we take the car to the track ...but I love the show and it keeps me pumped about get out in the shop
Way to step up, congratulations on getting your degree!
That was really good, especially the oops at the end. I'm glad to see I'm not the only one who makes silly mistakes! Thanks for sharing and an extra big THANK YOU for not editing out the 'oops' part.
5:00 newburn saying see it wasn’t my fault for the shifter backwards 😂😂😂 your a legend and mike is a awesome bloke for doing just like I was taught for saying who cares who’s fault it was we just need to fix it and learn from it you don’t see that very often now days
I've broken friends cars and friends have broken mine, it doesen't matter, we help each other fix it again👍
This has got to be one of my favorites. I love when Finnegan goes on a field trip and discovers shops like this.
Field trips are more educational than classroom time
Any motor guy that doesn’t watch to the end is really missing out on a ton of useful info! Ways to save your motor builds and more.
@sehhi vooty sometimes you only have 2 options laugh or cry and if you can't laugh at yourself you'll be a miserable person
What I really love about Finnegan's Garage is the unscripted and unedited conversation of the various subjects like injectors. I learned a lot too. In my career I worked with flow benches so I understood what was being tested. Thanks guys.
Thanks for leaving the 120/160 in the video... lot of channels would have found a way around it for sure! Now the question is, have you other engines with injectors you may want to check, seeing as you had a four/four mix?
Plausible the company packaging these screwed up. It looked like the same brand that had dead ones out of the box.
Great to see the blashemi back in progress.
Time for a dual throttle body setup.
Small for idle and cruce. Second linked to open for all the power.
Wondering if hellcat throttles could also be an answer..
cruce?
Always nice to see Finnegan on the weekends.
Yup
the weekends are for the homies.
Kinda like visiting rights, isn't it? Hey dad, let's race this weekend!
MAybe less drinking while working in the shed... 120's and 160's...
I'll vote for more drinking.
I've cleaned some injectors in the past with an ultrasonic cleaner.
And then I hooked a plastic tube to the input end, filled the tube with seafoam, set my compressor to my fuel pressure, hooked a 9v battery to the terminals to open the injector and blew the seafoam through.
Probably not ideal but for a backyard kinda guy like me I've never had an issue.
I didn't have an ultrsonic cleaner but I did a similar thing as you using Seafoam and a fuel pump instead of the compressor. Told me right away which ones were plugged or dead and got some cleaned up enough to get a street truck running.
Like you say... backyard fix that works good enough for me.
Nothing like.watching Finnegan while yelling at the kids to leave their mother alone and make their own breakfast. Happy Mother's Day!
Wow! Great video, thanks to Neuburg for always asking questions and Eric’s free flow of information.
I have a $400, 4 x injector tester unit that has helped me diagnose a few issues. I prefer working on a stuck or leaky injector before I have to pull a carb apart. 😁
I bought a injector flowtester with heated ultra sonic on alibaba for like 160$, AUtool CT160. Kept sticking open injectors on my supra. Seems to work well enough. Flows 4x 800CC injectors at like 35psi and you can vary the pulse width and 'rpm' independently with a whole bunch of different auto clean programs. The ultra sonic alone was worth it because I rebuild a few moto carbs every few months. Whole thing is basically a cubic foot, volume wise, so would be epic for something like drag week.
Would highly recommend it or one like it if you mess with injectors at all.
This is one of the best and most educational episode so far. 10/10 Mike.
I am so impressed that you not only have the best videos in our hobby but that you dont edit out the goof ups. Keep it real!
I like this channel. Everybody is just so real. Mike learns as he goes and laughs at himself in the meantime.
Great stuff with the not so surprising twist ending.
Laughing at ourselves for being goofy is the best measure of character...
...and you guys are characters!
This is a totally cool video that every EFI racer needs to see! BTW, the look on your face when Eric told you some of your injectors from that set were 120’s and some were 160’s was priceless.
When he found the 120 with the 160, all I could think of was sling blade, “ your out of gas” 😂😂😂
It ain’t got no gas in it
Mmmmhhmmm
Amazing video, nice job guys. Never assume " out of the box " is ready for use.
just to clarify the ejectors where probably fine. the real lesson here is to read your injector size lmao and make sure your fuel system is clean before you use new injectors. bigger injectors run more rich then smaller ones lol imagine that.
You can spend more money and get 'flow matched' sets, where they basically test them like this before they sell them, and you get the results so that you know all your injectors are running at (eg) 165. ie, what they actually flow, not just what the manufacturer said.
Hello Mike and David great video on testing the injectors can't wait to see the 55 back running again Wishing all of you well Take Care Guys
Aww man, your face when your man told you you had a mix of 120 and 160lbs injectors, 😂😂😂💯roadkill in full effect, you can take the man out of Roadkill but you can’t take the Roadkill out of the man 😂👍🏻
Mechanical science is flipping awesome! That was a hands down, an anybody on earth can understand that, demonstration!!!
That was Awesome to see the Fuel Injection flow bench test. Good stuff.
I installed a brand new one Edelbrock pro Flo 4 with full 8 port injection and had 3 dead cylinders because of dirty injectors that were completely stuck. Man your heart sure sinks when your brand new $2500 EFI system runs your motor like chitty chitty bang bang. 9v battery, cleaner, and air compressor got it up and ripping. Golden information in this video.
I think it's awesome that you put the whole video up. Showing 2 different lb injectors. Just shows you need to check out to make sure your stuff is correct.
The fact you posted this shows just how passionate you are about cars. Made a mistake and kept on laughing. Thanks for staying humble!
Eric and Pete are smart men that’s for sure.
A fresh engine and the fuel injection sorted: This could be really good. Can't wait to see Blasphemi run like it should.
I'd love to see him have to update the cage
about 10 years ago, on the top of Hale Mt. Alabama, we back flushed and cleaned a set of injectors out of a big block buggy, using assorted size hose, spray carb cleaner, a tank of nitrogen(we brought for charging shocks and air bumps), a set of jumper wires, one guy touching the wires to a battery pulsing the injector, and about 5 other guys holding everything together. wasnt the best way to get it done, but it worked. I now have an injector cleaner and flow bench in my shop
This is one of the best behind the success of finn speed and marine I have seen to date. Amazing.
Great episode! So much great info on the engine itself and especially the flow bench! So cool to see it in action, first time for me.
Ideally, you want to go with bigger injectors once you get to about 90% duty cycle. Above that, the fuel doesn't atomize properly and won't burn as well. You can see it when Eric runs them fully open, it's just three streams, instead of a mist. You need that mist as fuel doesn't burn as a liquid, but a gas, or miniscule droplets.
Sunday night over here, sit down to watch some TH-cam, Cleeter and Westen videos out, and yours pops up just as I sit down.
Monday can be dealt with tomorrow haha
Great content. My injectors have been my problems 90 percent of the time!
One day I’m gonna build a smaller flow bench so I can keep checking these things. They sit around too long with fuel in them and that isn’t helping.
Mike, enjoyed this video tremendously! I learned a lot about bench testing injectors. Thank you and Dave for doing this in a way we could see and understand it. Great!
This might not impress everybody but I noticed at 18:00 that the lettering on the logo above the bench was absolutely aligned with the crank and the dead-level of the bench top..
Good eye.. well crafted used engine room.. Built too perfection 👍
Awesome is an understatement here...Best video I've ever seen about Injectors! Very educational, informative and with details. Well done! I've definitely increased my knowledge and awareness regarding injectors (working on Harley Davidson EFI n/a M8 V-Twins here). Thanks for making and sharing this video. Tom M., Hawthorne Ca.
The fuel injector testing is so cool.
Awesome to be able to get a visual idea of what the injectors are doing like that!
Love watching this stuff, learned so much watching this. Great to see the atomization and how that combines the air & fuel mixture.
What's funny is Finnegan is actually like a teacher gold star lol 😂🤣
The only motor I ever built was a 1915cc VW. I put Webber fuel injection on it and had nothing but problems. I finally had the injectors tested and cleaned. They were filthy and hardly working. Put the clean injectors in and that motor ran amazing! It was the best feeling in the world. I didn’t built a piece of junk, I just didn’t clean the file lines well enough.
Can’t believe you guys were in my back yard and I didn’t even know it!! Pete and Kevin used to fill my nitrous bottles when I first started going fast!
WOW Pete is a humble master of his craft! purebred machinist and builder!
Best lesson was 120/160 mix up! Glad he showed that and IT CAN happen to anyone! Good Job Mike!
Let's GO! Get those injectors cleaned up, and this motor built. I swear you said I could drive this thing at some point!
Pete is a great asset to the drag and drive, and the drag racing community in general. Great to see you do a video with him.
Lots of good information as always. I've dealt with a few junkyard LS engines and always seem to have injector issues. I got an inexpensive little device from Amazon that can pulse injectors individually, and have found that tool very valuable. Sometimes all it takes for one to go from not working to working is a few bangs on the workbench. I have made it part of the routine now to use that little box to check them before first fire.
I just had the problem with a bad injector on my sons LS swap in his 80 Firebird, figured it out by the infrared thermometer on the exhaust, listened to each injector with a stethoscope, then made sure the wiring was good with a node light, luckily we got the last OEM injector left for his motor anywhere on rock auto
Yes definitely a a learning experience it is nice when someone sheds light on things like this so even brand new ones can be bad
I learned a LOT today! One thing I learned, is that any new injector set you buy needs to be tested before installation. Oh, and carbs rule!
That's gotta be very satisfying to see verification of the problem and settle your mind. Also, I think the reason the boost was down while the power was up is likely going to be from the cooling effect of evaporating fuel in the compressor. It's also likely that the alcohols, which are lower-boiling, will flash off first, leaving some of the heavier oily fractions of the fuel to get a momentarily-better seal on your intake valves (or lubricate the runners to let the air slip through (ha ha)). The pressure is going to make the oily fractions of the fuel linger like a fog, when the short chains evaporate off, and the end result should be really good at cheating a some extra octane out of your fuel.
A guy in the next town over who builds some of the wildest drag racing machines does some strange things with his fuel injection:
1. I noticed he installs an O2 port in every header tube, as well as the stock position in the collector. I understand as a minimum he installs O2 sensors temporarily and monitors them while tuning.
2. He used to build his own custom ECUs that would run closed loop on every cylinder. I think he buys them now but don't know what he buys.
3. With some of his engines, all of the injectors are all together, just behind the throttle body and he has internal features to help mix the air and fuel. With this setup he says it doesn't matter if some of the injectors flow different amounts as long as the total amount is correct for the airflow.
4. Almost 30 years ago he built his own fuel injector flow bench where the injectors flow into clear tubes with a measuring tape showing the levels. Originally to power the injectors he simply applied 12V through a simple on/off switch and all injectors were wired and switched on/off together. Later he used an old ECU from a junked car to drive the injectors. For a crank sensor he originally used a stock crank sensor and a harmonic balancer attached to an electric motor. Later he replaced the crank sensor with with a cheap electronic PWM driver. I'm not sure what he uses today but anyone could make their own injector flow bench using fuel injection parts from a modern car.
5. He has tons of other odd things (even 30+ years ago) like a home made flow bench that can be used to help hone cylinder heads, intakes, exhausts, throttle bodies, etc.
6. He also builds his own automated manual transmissions and custom made drag racing CVTs (that have bizarre shift patterns that take advantage of the engines rotational inertia), etc.
Great video, great info. Learned alot on injectors.
The fact that finnagins face went beat red when he was told he had 2 different injectors makes him not only human but was a priceless moment in the Darwin award of 2022
Thanks guys that was an excellent video . I'm smarter today than I was yesterday thanks to you .
LOL.... We have all been there... I swear, That is the dumbest feeling, when you finally figure out, what is going on, only to realize, how much money has been spent, how much time has been spent.. ALLLLLL on mixed matched injectors... Especially if your buddies are watching in real time the discovery. I know the feeling... Which also kinda reminds me of installing a fuel pressure regulator in the system BACKWARDS... But, the gauge shows we got pressure...LOL
You bet the crap out of those motors Mike. Have been following your videos now since road kill day's. Can't wait to see the Chev back down the track. 💯😂 Aussie Fan 🤟🇦🇺😎
Starting at 27:37 that's some good info there. What big dog said before too I'm just giving reference to what he is talking about...
Good stuff Finn!
Hey Mike and Dave awesome video on the do,s and don't's of fuel injectors And most of all read your injector sizes LOL
WoW! Fifty shades of red on Finnegans face when he found out about the 120-160 error! It happens, and it was cool to see the mistake taken in stride. Too funny!
The last few minutes of this video are absolutely awesome!
When you discovered the issue with the 120/160 injectors ,not gonna lie, it made me feel a little bit better about some of the bone head mistakes I've made and beat myself up about LOL thanks! Great episode.
great info on injectors Finn.! A lot of this info is hidden behind closed doors but bigun was sure being transparent and open. this could be a hidden art!
A close up camera with software to slow down the frame rate to view each injector coming out of the test bench would be awesome. That might tell if it's a "one hole" problem or up above the nozzle affecting all delivery holes.
This machine is so awesome. So is this vid.
I remember first hearing about Pete's shop from an episode of Skid Factory a few years ago. He allowed the boys to come in and totally rebuild a Barra for a Mustang!
I took your Ford Explorer while I was rebuilding it to him. I learned a lot. New doesn’t mean good. Take it to this guy and you will know for sure
Really enjoyed the info and hilarity with the big twist at the end Roadkilled AGAIN!!!!🤣🤣🤣🤣
I didn’t realize that fuel injectors were sensitive like this, Nor did I even think that they would flow differently due to something as simple a dirty fuel line. This puts perspective on something I’ve been trying to understand for awhile.
All together now…
“And Because Roadkill”!!!
Just dying!!!
I thoroughly enjoyed this ENTIRE video! Thank you for such enlightening and scarce information.
Glad you enjoyed it!
Since a holley injector driver is used. Write your control program for fixed pulse width but also variable pulse width. So it cycles from 250 pulses a minute to 5000 pulses which would be 500 to 10,000 rpm. Lastly write a program from 250 to 1500 then 3500 pulses like you are staging. Coming up on the 2 step then launching. Set it up to run that cycle 3 times in a row to check the volumes..
Find silicone orings. At least 2 per graduated tube to allow you to adjust the oring heights to see if the injectors flow differently.
I wish roadkill would come back to TH-cam, even if it's a few seasons behind.
Ain't anyone's fault but Morortrend's and TH-cam's.
@@daniellewis1789 I dont blame them at all for stepping away from youtube. They are a big content creator that should and now do boast their own platform. Its affordable and you have access to everything Roadkill and Hot Rod without any of TH-cams nonsense like ads or pushing unwanted videos/content.

Killer information in this one guys! 👍👍👍
Finny, you know that I LOVE Blasphemi, but I'm REALLY digging on that LS twin turbo Continental.
Continental or Cadillac
Loved the injectors test found out a ton of information about the magic of the injection systems
Great to hear!
Many , many thanks. That was one of the best videos ever; right on !!!!!!!!!!!
What an awesome episode 👏
They mentioned rob, I visited his house few times in bowling green when he was working at Holley. Cool guy and it’s awesome you know each other
I love the fleet you're putting together. Don't let people get you down with their complaints. 💯
Great video. Like the fact you show your mistakes. Hopefully we'll learn from it.
52:25 latent heat of vaporisation, The fuel injection is taking heat out of the air charge below the rotors instead of above. just like a blow through carb. That's assuming you're spinning the blower the same and you're not just making more power with a lower driven but more efficient blower.
Both could be true.
I was thinking the same thing
Inside the blower after the air is pressurized, adding the fuel should “cool” it denser and lower the “boost”.
So cool!
But running all the fuel through the blower is taking up space in the blower that you’d like to be oxygen. That’s not a good thing in a class with a size restricted blower. While cooling is good, stealing air is bad
Pretty well established by roots blower guys that fuel on the intake side cools your IAT down much lower than injecting at the port
@@Turbochargedtwelve The nice thing would be if some were above/level with the rotors, and the rest below. It would act as an intercooler without taking up space in the blower.
Also, the extra fuel could be doing a better job of lubricating the blower, making it more efficient.
That said, I don't think this would make a big difference.
Nice to know "it's not just me", stupid mistakes can happen to people who know far more than I. Can't wait to see what car will do at drag week 2022!
very interesting and relatable. all I/C cars do run injectors and it’s nice to see a resolution to the problem.lesson learned keep your fuel system clean.
That's definitely something because I have an alloy block, alloy heads and bolts instead of studs and it's heavily supercharged - no issues.
Great content...I have plenty to consider before going fast w/ aftermarket parts. Thank for making me and hundreds of others feel better about wasted $$$
For us. Just because of our aviation background if we have injectors we know will be sitting till the next service or even our cars now we change injectors every 6 mths no matter what and we always will leave them sitting in engine oil in a bag. Keeps everything lubricated it’s clean minus the install but just pull them out 20 mins before you install let them drip off on a rag and they’re perfectly fine by the time you toss them in. Never had an injector hang or clog in any way in over 15 years
Wow. What an educational video. Thanks guy.
I'm so stoked you got went with this shop, real life garage not fancy as shit feels more like home
At 54:58 the look of Finnegan's face is priceless when Bigun told him that some were 120s and some were 160s. .
Hey Finn just wanted to mention something that might help. The closer the injectors are to the cylinders the better it is for power since the evaporating fuel pulls out heat. That’s why direct injection has a greater power potential compared to port injection. Intake air temps obviously have an impact as well but in terms of the fuel path the technical term is latent heat of vaporization. That’s one of the mechanisms that the better fuels like E85 and methanol bring to the table over regular gasoline.
Checking each injectors dead time and voltage offset was the best thing Iv ever done to help my idle and low pw flow numbers.
Ok... that Injector test setup is slick!! Mike, dump the boat in the water... can't wait for more Game Over videos!!!
Our hero’s are human after all…absolutely great video
53:48 I never knew that injectors, that you could clean them just by blowing through them in reverse. THAT IS SO COOL.
I learned a lot about injectors and the biggest thing being to read the numbers on the side of the injector to see if they are all the same! 😂😂
