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!
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!
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
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.@@hydrocarbon82
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.
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 RU-vidr 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.
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.
@@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)
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.
@@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!
@@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.
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.
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.
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?
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.
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?
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.
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
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
@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….. 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 👍🤘👏
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
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!
