- WHAT MAKES MORE POWER, CARBS OR EFI? WHY NOT RUN BOTH? CAN I RUN A DRAW-THROUGH CARBURETOR ON MY M90 BLOWER? CHEAP, JUNKYARD M90 CARB MODS MADE EASY! CAN I COMBINE CARBURETION AND EFI ON MY JUNKYARD-BOOSTED LS? CAN I TUNE THE CARB WITH EFI? DOES A DRAW-THROUGH CARBURETOR LOWER THE CHARGE TEMPS ON A BOOSTED APPLICATION? IS THE LITTLE M90 BIG ENOUGH FOR A 5.3L? CHECK OUT THIS VIDEO WHERE I RAN THE M90 ON THE CAMMED 5.3L WITH HOLLEY HP EFI, THEN ADDED A 650 HOLLEY CARB TO THE BACK OF THE BLOWER, THEN COMBINED THE TWO TO DIAL IN THE A/F MIXTURE.
okokokok.... twin m90s and dual quads. You'll be the coolest kid in the neighborhood
You mean dual-dual quads right?
Richard is one of the worlds greatest mad men 🙂
“And now this weeks answer to the question nobody asked!”
I love it
a carb on the back of a m90 is something only its mother could love but by god i want wayyyy more of it.
I hate to say this BUT THATS ONE OF THE COOLEST THINGS EVER! If someone told me that they were going to do this I would have said no way it would work. But you have proven me wrong sir. I love it. The only thing is do you think it would run on the street. Would the gas kill the blower?? I love this!
It might eventually put some wear on the rotors
Why would you say it wouldn't work? People ran carbureted supercharged engines for years b4 EFI ever existed! Why would the gas kill the blower or why would it cause any more wear than the EFI would? There is other fuel to run that that craptastic E85. You guys have some really strange ideas. It seems to me that you are all hung up on issues caused by the electronics not the carb. Again some really fast cars ran without any electronics. Wow, just wow!
The blower will develop frost on carbed e85...also, it will strip the coating off the rotor pack, to no Ill effect. First hand experience with both.
sounds badass
How did the bearings on the blower hold up (miles?) I heard the fuel may wash the bearings and fail. Thanks
No bearing problems to mention. Ten thousand miles put on that combo without worry.
Wish this was done on a modern direct injection motor that is fuel limited from the factory, like the early 3.5 ecoboost. Add on carb, e85, and a centrifugal supercharger feeding the tiny turbos could get crazy.
The only problem is you need a special (aka old-tech) carbon seal turbo instead of the common dynamic seal (piston ring style) turbo used on pretty much everything since 1990. The fuel gets past & interferes with the thrust bearing lube.
Is that an e85 problem or a general fuel issue? My first thought about adding fuel to starved direct inject engines was propane, but I only know enough to get into trouble.@@hydrocarbon8272
You can't make the engine leaner with fuel injection assisting the carb unless you have a controlled vacuum leak that the computer runs based on the O2 readings-like a large IAC. Speaking of, another CZcamsr is selling a product called Carb Cheater. Which I believe is exactly that, a controlled vacuum leak. I would love to see you test it on a carbed v8.
there is no vacuum leak at WOT
Using both (efi and carb) could be a relatively good way to add power on a direct injection setup. A carb would be cheaper than the high flow direct injectors/pump/etc and add a bit of charge cooling.
Richard I am so thankful you made a video like this I Am David Bates from Montana I've been thinking about building something similar for a 2.3 l Ford Lima engine I have spoke to you about it before first time about a year ago I'm so happy thank you
TWIN M90s!!! triangle supercharger hat for the ram.
NEARLY DONE
@@richardholdener1727 As much fun as your having with these, we should have known.... I am curious if the seals in the blower are gas safe, I know the coating really isn't on them if there is alcohol in the gas..... There was a Fiero runnign around years ago with a 4.3 buick v6 swap with two of the chargers on it.
That’s exactly what I was gathering parts for on a 351w in a foxbody before my health took a crap. Had everything for it but never could work on anything due to health issues. Hope to see it on this channel!
It would probably be better to have one supercharger feed the other supercharger.
Boost loves boost. 😎
@@michaelgarrow3239 Running one roots super charger into another roots one wont make more air mass. A roots supercharger displaces air, the intake compresses it because the engine can't use all of it. If you used two of the same roots style, there would only be pressure from heat build up between them.
Hay I love it! Now this once again, is Super Richie engineering at it's best.
I think it would be worth it for a cheap easy way to run meth/alcohol injection. Methanol/alcohol only to the carb before the blower with pump gas efi below the blower. Obviously the carb would have its own fuel system (running a different fuel) so shutting the pump off turns on/off the secondary injection, which could be controlled by an ecu setting that was also changing timing (added for the alcohol/methanol to make the desired power) at the same time. Carb(s) would always be used as the throttle body. This would be really cool to see on a drag & drive or street/strip setup.
I would love to see this, honestly it's a brilliant idea
@@mross302 I would too, & honestly I may give it a try on my first gen rx7. I've been thinking about possibly twin charging it anyways. (Supercharger & turbo)
Might as well just go with two-stage fuel injection, like the fuelers and floppers do. You'll get the cooling effect, and maintain more control.
Rollin Rollin Rollin keep them horses Rollin 😮😮😅
Great stuff Richard! I don't know how you think to try some of this stuff, but I'm glad you do!!
The science no one asked for, but the science we didn't know we needed
fun is important too
How about using throttle body fuel injection to get the advantages of charge cooling and precise air fuel control? I've always thought TBI was the best as long as you can package it and get good fuel distribution... that leads me to wonder how cylinder to cylinder fuel distributing was with that carb setup...
Theres supercharger kits out there with a 5th injector pre supercharger for some extra cooling. Not as efficient as WMI, but a very simple solution to integrate on an already fuel injected car.
this.... this is just too awesome! even had the supercharger idle surge!
Oh yeah! That is hysterical 😂
K&N use to offer a spacer with efi injector & ecm, price was comparable to a TBI like FiTech tho. Funny cause I had the spacer idea some time ago, glad to see it worked.
Coolest test I’ve ever seen
This vaguely reminds me of my buddy Matt Tinnin's M122 Cadillac blower. He adapted a methanol dominator to it, and it made a ton of power on a 6.0.
Love it! The set up is awesome! Love the data!
Thunderhead 289 has a product out he calls it carb cheater. Its a metered vacuum leak basically keeps optimal stoic ratio. Was a pretty big deal last year but have not heard much since. Could you do a video on it?
you don't want stoich at WOT
Reason for asking, I'm thinking of a Frankenstein Design on my 565, 8-71 bbc. Going to a Holley twin super stealth 4150 efi TBI’s and thought it’d be wild to blow through those while they’re on top of the 8-71 lol.
I had a 32mm carb on a 232cc bike with tiny jets. Had a ecotrons efi kit and all I used from it was the injector and o2 sensor.
I don't remember what board I used but all it did was read the o2 sensor and use the injector to try to level it out.
Was a good learning experiment haha.
Ummm, maybe the lot of you are too young to remember but there was a time, long before EFI ever existed, that the only fuel delivery system that you could use, with a supercharger, or without, was a carburetor! We even had indoor plumbing to take a whizz on your break from building! I swear, it makes me laugh when people think/act like they invented something or are the 1st ones doing something that us old hotrodders were doing decades ago, lol!
You missed the point of this video-Which was about adding a carb to this specific M90 (V6) blower that originally ran with EFI. It was not a universal statement saying this is the first time anyone has ever run a carb on a blower so stop making things up to then complain about and just enjoy the videos on boost
Makes sense. Run the carb lean intentionally and let the efi add more fuel
Yeah.... WAAAAYYY more sense than running a proper EFI.
Time to put the elbow and carb on a truck intake. ELBOW RAM!
YOU'VE GONE MAD , I LIKE MAD 😂
First 👍's up Richard thank you for sharing 😊
This is great stuff Sir!! ThankYou
I always wondered if you could run a blow through turbo carb on top of fuel injection as a intercooler.
YES
thats absolutely insane im on board
Richard…..
I’ve always wanted to see a gasoline example of a twin charged engine on the dyno.
I’ve tried to persuade many people to do this… Seeing this Eaton setup on this ls would be a perfect attempt.
Put a single turbo on it, and blow through the butterfly into the supercharger… what does it do? Is it worth it? What’s the benefit?
Please!!!! Lol 👍🤘👏
please see the 3800 compound video where we used a turbo to blow through this same M90 blower
Ok 👍
Just watched it. Pretty impressive what it did there… just so hard to imagine or estimate scaling it up. It’s the same thing, but at the same time like comparing an apple and a banana lol.
Talking 9.2L big block and a 7L blower lmao.
I’ve searched the entire internet and can’t find a decent example. Besides an 8v92 Detroit lol. Which is also way off… 🙄@@richardholdener1727
CARB CAM FTW!
Ok so I have a question, what if you ran that carb setup on a efi Intake by itself? Would it work with blow through? Or perhaps you could try a compound setup with a turbo on top of this combo?
More ls content. Great..
No,twin M 90s and twin carbs,do it please and thankyou
that is a sweet rig job. :)
I wonder how it would be to run a small amount of castor oil in the fuel to keep the gasoline from eating the coating on the impellers
Stock cam supercharged cathedral port 4.8 or 5.3 versus cammed square port 6.0
I wanna see what this supercharger will do on a smaller engine. Like the pontiac trophy 4 cylinder.
Put two of those on a cross ram intake. I guess you’d have to make a new lid.
im curious to see EGT on each exaust befor lean specialy w dhis set up
I was going to run a carburetor on the back of my m112. Good you did a video on this. I was told it would not work because fuel washing out the bearings. Could this work with an intercooler.
Any comments on bearings?
Hey bud can you test 4 to 1 long tube headers vs tri y long tube headers? On a LS or LT block please?
The test would only be those specific Tri Ys vs those specific 4:1-there is not a universal change between those header configurations
Now you just need a Mad max boost toggle and swap between the 2 fuel systems with different fuels.
What if you pair one of these with like a rear mount turbo, would the turbo blow up the supercharger ?
I have compound (m90/turbo) videos up
Yay MOAR Super Richie dicking around silliness!
Does anyone know if there's a company that makes an adapter plate to put the m90 on a 4.3 vortec? I briefly searched it, but only came up with unreliable forum junk and one cool story in "LSmag" about some guy named "Richard Holdener" who made an adapter plate to put one on a 4.8.😂 That last story sounds familiar!
Love this
12:18 Have you ever evaluated the carb cheater by ThunderHead289?
I asked the same thing then found your comment. Great minds think alike.
never heard of it
@@richardholdener1727 It's an electronically controlled vacuum leak to lean out carburetors during rich events.
I had a 1985 Lincoln Mark series 302 high output engine coolant temperature sensor signal change and throttle position sensor change 33.3 Mi to the gallon
SENSOR CHANGES WON'T DO THAT
@richardholdener1727 installing a resistor inline with the ect & iat sensors will in fact change things. Was my tuning method in the early 2000s for bolt ons. Project box with rotary switch to switch between resistors for tune-up for temp change. Can't cheat it much, but it does work
Richard can you please do a 7.3 idi video and even turbo it please and thank you!!!!
diesel? I don't run them on the engine dyno
@@richardholdener1727 damn. I was hoping to learn some as I dove back into my 7.3 idi
@@richardholdener1727 thank you for the response sir!
I would think the fuel from the carb would keep the supercharger cool
I probably missed it, but how do you identify the different Gen of blowers!
inlet size, discharge size, throttle body
@@richardholdener1727 I was hoping that it was the casting number or something, lol. Thanks
Are you going to run an E-85 carb an just for the hell of it the low rise intake?
the low raise makes less power
@@richardholdener1727Yes, but by how much would be cool to know.
Was it blower surging at idle?! People pay good money for that sound...
You can fix that with the correct power valve…
Was the boost curve same with efi & carb ?
yes
So whats na numbers
3:45
Science 😅😅
Didn't you post this already
THIS CARB IS ON THE BACK OF THE BLOWER-THE OTHER WAS ON TOP
@@richardholdener1727 I realized that after. Torquer monster
Your teaching kids terrible safety habits The way you cut that tubing was ridiculous You should be ashamed
and yet
Your species would never have left the cave…
@Richardholdner you are my idol bud
