- Опубликовано: 7 май 2022
- 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-carrillo.com/
Total Seal piston rings: www.totalseal.com/rings/gaple...
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.com/product/8-7...
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/products/fuel_...

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!
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
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 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!
Nothing like.watching Finnegan while yelling at the kids to leave their mother alone and make their own breakfast. Happy Mother's Day!
Always love watching your videos. I work right across from where your c10 sat for a number of years at Scott’s hot rod shop and live close to where you guys filmed a number of roadkills at the cam airport. I’m happy to support your bad decisions
Ventura here!! 👍
You work near a spot where one of his cars sat for awhile...hell you're damn near brothers now
I'm a proud supporter of bad decisions and of global warming (big blocks with open headers)
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.
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.
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.
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
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.
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.
Love watching this stuff, learned so much watching this. Great to see the atomization and how that combines the air & fuel mixture.
I like this channel. Everybody is just so real. Mike learns as he goes and laughs at himself in the meantime.
Wow! Great video, thanks to Neuburg for always asking questions and Eric’s free flow of information.
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.
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!
Thanks Finn! This episode was very informative and interesting. Looks like we all learned something about injectors and bench flow testing!!!
That was Awesome to see the Fuel Injection flow bench test. Good stuff.
This is one of the best and most educational episode so far. 10/10 Mike.
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 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!
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.
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.
Been a fan of Eric's for a long, long time. Awesome stuff. Thank you
I really enjoyed watching y'all i get to learn something new every time I watch y'all. God Bless
Mechanical science is flipping awesome! That was a hands down, an anybody on earth can understand that, demonstration!!!
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 😂👍🏻
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!
Wow this is incredible learning about the injectors! That was very educational to see. Thank you for showing that
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
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
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 $$$
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.
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?
What an awesome episode 👏
Such a great video! Learned so much and great to see progress on projects you enjoy. Thank you!
Great video, just starting to learn about injection systems. Bought the edelbrock pro flo 4. Great things to look for when I go to fire up the motor. Thanks again
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.
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.
Eric and Pete are smart men that’s for sure.
Thanks guys that was an excellent video . I'm smarter today than I was yesterday thanks to you .
The fuel injector testing is so cool.
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
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 love the fleet you're putting together. Don't let people get you down with their complaints. 💯
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.
What's funny is Finnegan is actually like a teacher gold star lol 😂🤣
This is one of the best behind the success of finn speed and marine I have seen to date. Amazing.
Awesome to be able to get a visual idea of what the injectors are doing like that!
I wish roadkill would come back to RUclips, even if it's a few seasons behind.
Ain't anyone's fault but Morortrend's and RUclips'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 RUclipss nonsense like ads or pushing unwanted videos/content.
@@madmod I blame them for pulling the Roadkill back catalog and paywalling a series built on free access.
@@daniellewis1789 They are the largest automotive magazine that employs over 100 people. Someone has to pay the bills and with youtubes ridiculous, overly stringent demonitization policies, they had to leave for the better of their company. I agree a paid subscription is less ideal than free entertainment its hard to make content for free.
@@madmod They're welcome to keep pouring good money after bad on their tiny walled garden subscription. I'll stick with people who don't pull their previously released content.
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
I thoroughly enjoyed this ENTIRE video! Thank you for such enlightening and scarce information.
Glad you enjoyed it!
WOW Pete is a humble master of his craft! purebred machinist and builder!
I feel like a match race with Blasphemi and Miss Fitt needs to happen this year. #makematchracinggreatagain
Put that old block in a hot rod and call it "The spirit of blasphemi".
Many , many thanks. That was one of the best videos ever; right on !!!!!!!!!!!
Best lesson was 120/160 mix up! Glad he showed that and IT CAN happen to anyone! Good Job Mike!
Amazing episode. Really well done. Should have named it our fuel injectors are shit watch us fix them.
Crazy that is not the first time I've seen this. Thinking purging the fuel system to get contaminants out might be a good idea to prevent this, or they might be screwed from the factory. Given they are all the same flow rate :)
The last few minutes of this video are absolutely awesome!
GREAT EPISODE!!! More like this please! 😃
Wait did I miss something ? I thought the caddy was your drive around with family and friends street hot rod..if so why would you want to change the race dna of Blasphemi ?
There's just something about those good ol' boys from the south. They understand the big picture and know what's really needed and what's just junk. I grew up with my best friend racing open modified gocarts on the dirt tracks around North Carolina and spend many a night in a garage of a "guy" who's got a reputation as an engine builder, or another "guy" who welds Chromoly. The state is littered with smart, sensible people like that.
Most educational video in years. Thanks!
The fact you posted this shows just how passionate you are about cars. Made a mistake and kept on laughing. Thanks for staying humble!
Audi used to use diesel engine blocks in their 80s ralley cars because the gas blocks couldn't handle the power and torque. Maybe you should look at something like that as well?
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.
That’s some really cool info on injectors to be honest, thanks for sharing the video with us. Glad to see blasphemi coming back together, can’t wait to see the caddy get finished though to be honest.
Great video, great info. Learned alot on injectors.
Could you put 2 stroke oil in the fuel system before you store your injectors or engine? Whould that help?
I've heard is 2 stroke is bad for catalytic converters. and the oil thickens when its left out in the air. I've seen that on 2stroke carbs where the fuel evaporated and left the oil in the carb and clogs everything.
Use alcohol fuel lube, like guys that drag race alcohol cars use.
In all honesty you've blown up like 6 Hemis now. Maybe it's time to move on to a more reliable engine.
Go back with chevy.
Wow. What an educational video. Thanks guy.
Those dudes know their stuff! Very cool video!
Use me as a I hate amber heard button
My mind is blown, awesome learning episode!
Excellent video,glad you guys were able to make it so informative. Started my morning contemplating paying to have my 1150 dominators split since I need to fabricate a new top for the tunnel ram anyway but now really considering an E.F.I. setup. Happy to see you getting problems ironed out on the 55. Keep up the great work. 👍
I've always loved the efi setup over anything
Sunday night over here, sit down to watch some RUclips, Cleeter and Westen videos out, and yours pops up just as I sit down.
Monday can be dealt with tomorrow haha
I'm so stoked you got went with this shop, real life garage not fancy as shit feels more like home
Yost is a badass!! Love his car!!!. Awesome information, I know more about efi than I ever thought!! And question everything! Lol Awesome job guys 👍
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.
GREAT video! I love that y'all can laugh at yourselves
That was great,atleast you show your mistakes ,with all the equipment in the world we all make them 👍. Looking forward to seeing Blasphemi get it's fresh engine 👍👍
Killer information in this one guys! 👍👍👍
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 information on injectors. All the best for the rebuilt on the hemi.
Awesome video!!! - They always are, but this was fun and educational!!! - Thank you!!!
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 🤟🇦🇺😎
Wow that new block is amazing! 💪✌️🤙🇺🇸
Schoolboy error Mike. Good to see we're all human. Bless individuality. Very educating episode. Mick
Mike , great video. I learned alot. as always thank you for your honesty. we've all been there before. keep these tech videos coming.
Too many people edit out their mistakes to make it look like bad parts instead of teaching hey I screwed up don't do this
Awesome information thanks fellas!
Awesome video. I'm excited to see Blasphemi run again.
Another awesome and informative episode 👏
Great informational and interesting video about the injectors and machines. Then the hilarious yet not surprising discovery at the end!
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
Great video learned a lot you guys are hilarious Love Blasphemi And all the other projects two thumbs up Finnegan
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.
