Warped it on the side that matters least. That's the intake area, low pressure. Seal really needs to happen around the outside, not a lot of grinding done there.
Awesome video! I currently have a Twin M90 setup on a Small block chevy i fabbed up a few years back. I took my blower housings to the band saw and cut them off right at the back of the bypass holes. I then welded the bypasses shut and fabbed up flanges on the rear of the blowers to connect an upper intake to. I fabricated my lower intake on top of an old performer intake, basically welded a box on top of the 4150 flange, then funneled it up to fit the base of both M90's. I did all of the lower intake welding first so i could bolt the blowers down to the base before welding on the rear of the housings. I also did my welding with the blowers assembled. I feel you might have not had nearly as much warpage if the front cover was in place at the time of welding. Or even make a dummy cover out of 1/4 inch steel to hold the large opening in place while putting the heat to it. I am running a serpentine pulley on the crank off of a TBI, chevy truck (not sure what diameter that pulley is) with stock pully's on the blowers and it makes about 11-12 PSI at 6800 to 7K. I was running a 750 Mechanical secondary double pumper with 78's in the front and 86's in the back, but with a power valve block off... Unfortunately my lack of knowledge on setting up the carb ended in me running face of the sun lean and i melted a really nice set of blower pistons out of it... Really should have boost referenced the power valve properly.... Right now it's back together with a stock bottom end, and if my math is correct, at least from the Blower Shops equation, I actually need to bump up to a 1050 to feed what the twins are making....... It's so cool to see this stuff tested on a dyno while making all of these wild changes, Keep it up!!
@Mrshotshell it depends on how you rout it, and which m90 you use. I have seen it don't on a couple flat head v8's where the old hot rodder built it so the carbs were over the blower.
@@richardholdener1727 It's interesting you did this. I started thinking that it would be interesting to see, instead of drilling a hole in the top of the supercharger, somehow adapt a side draft carburetor in place of the throttle body to eliminate the elbow. The Impala I have has the L67 supercharged engine and it would be cool to replace the throttle body with that side draft carb and be able to close the hood.
Gota love this crazy stuff. I wonder if you could have found a peace of aluminum pipe and thread it in instead. But with fuel in the blower I am not so sure the distortion is that much of a problem.
I agree. I saw a vid on here if a guy who put an m90 on an olds motor. Used the stick cast iron intake with a flange jb welded onto it for the supercharger. If that works it’d 100% work with a carb flange
I had a yamaha 3 wheeler the previously mangled the mounts on the head and lost the rubber manifold. It ended up a jb weld abomination and behold the oxygenated gasoline made the jbweld melt!!! 😅 so no jbweld is a real temporary solution once gas with clorinated ether hits it
I always wondered how that would work out, waaay outside of left field on that one and over the highway! Right were my thinking goes! So damn cool to actually see this!
Use a milling machine and press fit the pipe with an arbor bushing after you apply loctite to the contact surface, then just use a cutter to precisely mill of the excess that protrudes beyond the inner case surface.
@richardholdner question sir. That blower is designed for a v6 and not really effective for feeding a v8 BUT if you run 2 of those on a v8 but have 1 blower for left side and run 1 for the right side keeping then separate ( 1 for 4 cylenders and thr 2nd blower for the other 4 Cylinders ) you would now see more Efficiency and easier power gain . . It's like your taking a turbo from a semi and putting it on a car ( awesome power ) but if you took a turbo for a car and put it on a semi it would lose power infact it would restrict power . Great video and keeping a open mind and search for knowledge and keeping the questions WHAT IF alive
Technically the blower is not designed for any motor configuration, but rather a flow or power output. It works fine on milder V8 applications, we have made over 600 hp with them. Twins are already in the works
best way is to do small increments 2 inch welds at a time , let cool , do it in 4 places around the circle then weld in between , this prevents warpage, it takes a little time
Wonder if low temp aluminum brazing rod would hold, they are "low temp" but not 200° low temp, they still need a bernzomatic to melt and its flame is waaaay hotter than engine temp.
I had no idea you were going to modify it to like a b&m mini blower or that the rotor pack would work that way .... I wish you were closer I could have run a boring head through the case to make it right after the welding .... Looking forward to the video on rear Mount carb which is how I figured you would do it ..... Crazy what you are getting out of this little supercharger
Im thinking carb on the elbow would work better , at least as far as fabrication is involved. On a SBC, you could run an msd short distributor with the crab cap and a front mounted ignition.
@@richardholdener1727 best way is to do small increments 2 inch welds at a time , let cool , do it in 4 places around the circle then weld in between , this prevents warpage, it takes a little time
Dude your my hero!! I’ve dreamed of doing this a hundred times but never had the guts...thanks for proof of concept! Don’t know if I’ll ever get to try but thought of grabbing a $100 283 sbc.. I bet you could make 400+ for under $500. You. Should do a 1hp per dollar challenge... also I wonder if aluminum mig spot welding would put less heat into the case and help with the warpage... YOU DA MAN!!!😎👍😁
you dont have to chop the supercharger. just make an elbow that bolts where the throttle body was, run a pair of SU44's, any decent side draft, whatever flows enough... on the bonus side, that means you get to fit an intercooler core underneath the m90. for a down draft you can point the elbow down or to the side and drop the carb... but that doesnt help velocity. aluminium doesnt weld right with spot welding. you have to break the protective layers otherwise it's going to leak like hell. short dashes might work, however. think 2 inch strips every 4 inches. heck, i remembered, there's the predator constant velocity carb, that thing has no float bowl, it might just do what a throttle body does just fine. if you find one...
Richard I Am David Bates from Montana I contacted you about a year ago about putting an M90 supercharger on a 2.3 l Ford Lima engine I still plan on doing it I want to learn more about the video where you had the carburetor on the elbow
@richardholdener1727 yes the video where you have the carburetor going in to the rear on the elbow I want to learn more about that one see I told you I was putting a two-barrel carburetor on mine and you suggested I put a 4-barrel carburetor on their I am a big fan of the 2.3 l Ford Lima engine I have a turbo motor I'm going to put in a 79 Ford Pinto now
Yes I have an Eaton M90 supercharger and a 2.3 l Ford Lima engine at first I told you I was putting a two-barrel carburetor on there you suggested a four-barrel
I remember a 24hrs of lemons car that had a 455 olds with two m90s mounted case forward with a plenum and a quadrojet. The article said that had an intake backfire which sent the whole assembly to the moon.
I think you should v6 that blower i have a vp ( buick v6) with a 6v71 Detroit blower and twin throttle bodies (some videos on my channel) not tuned stock injectors and it runs will be interesting once injectors and tune done. This did do alot better than I expected though
Doesn't matter if the air inlet is at the top or at the end. Almost all roots blowers, even big-boy 6-71s, 8-71s, etc., have twisted (spiral) rotors and they feed just fine from carbs mounted on top. But I agree, leaving that huge "dead volume" of the original air inlet path from the (blocked off) TB mounting flange to the blower case inlet had me wondering if this was going to work very well. Apparently it works fine.
I just googled Thunderbird m90 and it looks like the intake port is in the back very similar to the GM m90. It does appear they flipped the entire supercharger upside down so the exit port is on top instead of the bottom. Unless it changed by year and I'm just looking at the wrong one I don't see how it makes anything easier for Richard.
Time you invested in a good 3d printer. You could have ground off the ribs on top, and 3d printed yourself a blower to carb adapter and glued the thing on with some kind of epoxy glue.
Wonder about the low temp aluminum brazing rod, that stuff is actually gives a pretty strong bond. Can you build a carb adapter plenum to go in the original m90 inlet?
Holy cow, that was cool!!! What if, you used some form of JB Weld (or similar) on the Super Richie Blower? That should eliminate the warping. Also, do you think that tall "plenum" played a part in the torque numbers? This is nutty, I love it.
See now that would be perfect mod to do and place it in my 97 s10 with the 4.3 vortec like im wanting to do. The throttle body would be in stock location then. Add this to a 4.3 L35 please
I fabricated an adapter that doubled as a 90° boxed elbow to come off the rear of the supercharger. (Replacing the throttle body adapter) It located the carb above the supercharger. It worked fairly well on a sbc 350 but I'm not sure ot was worth all the effort. I had all the needed materials and if I worked for .50 an hour, then it was definitely worth it. 😂
Dang it. It’s turned into a suspenseful TV show. “ the adventures of Super Richey, TV show. “ Does the m90 catch fire ? Does the all aluminum 5.3 let go? Did he go lean for the last time on this engine? All this and more will be answered on the next episode of the adventures of Super Richey 😂
I saw a video of someone mounting an m112 from a Jaguar upside down onto an Oldsmobile. He showed some internal baffling around the gears that needed to be ground away to keep them well lubed. I don't know if the m90 is similar but it's probably something to look into.
@@TheInsaneShecklador you are correct I did also comment the link to the video and corrected that it was a m112 but it’s not there now 🤷🏻♂️ oh well. Think my brain thought it was an m90 because I initially had watched it I had thought that it’d be much easier to do with an m90 because you don’t need to flip it upside down
@@TheInsaneShecklador oh wait you’re replying on a different comment. Duh! I had brought up that video to another guy. Yeah he added some grease nipples to the bearing on the impeller shafts as he feared the gas, that wouldn’t normally be in the mix with a efi blower, would slowly clean it out
Another awesome video Richard. I had a related idea for an experiment you could do for us. What happens when you use a carburetor and an elbow instead of a throttle body and injectors on an LS truck intake? Are the LS truck intake EFI top end power gains over a dual plane carb intake due to intake geometry, even fuel distribution, or something else? Can a carb on a truck intake make similar power on the same intake that normally uses port injection? Will it be way worse? I assume worse, but want to see this for science, and to hear your thoughts.
Fuel distribution becomes an issue based on other testing I’ve seen. I think it’s because the carb would be on one end and the air mixture has to wind around a fair bit. Even with a dual plane it’s a pretty even and reasonably direct path.
Richie, how about making a AFrame style intake with a blower in each side? I suppose you could inverse that as well...... Though oiling could be an issue ....just an idea
It would have been lean because the power valves wouldnt have opened. With that little huffer pumping away furiously under the carb, the powervalve reference port in the baseplate of the carb would have been seeing much much higher vacuum than it would at WOT on an actual engine. Also, is there any reason you didnt just weld a 4bb carb spacer straight to the blower housing? (Mill all the ribs iff first, and weld it straight on) perhaps welding two things of a more similar thickness/preheating the blower housing "might" have reduced distortion. /probably not. At least then youd have something someone could then fit to a car. As lol/click worthy that tall stack is, its not really very practical in the real world.
@@richardholdener1727 need to externally reference the power valves with a boost signal. Id wager you must have a whole cupboard of boost modified carbs there?
@@TheInsaneSheckladoryes it clould work but i try to keep it cheap and simple, i dont like the idea of adding moving parts and weight.. i heard that you can reverse rotation some eaton but only few of them..

It's probably easier to build an adapter for the stock throttle body location.
did you watch til the end of the video?
@richardholdener1727 I did, but I was commenting while watching it. I have seen a couple old flathead running that setup for years.
That might not be an option because of firewall clearance especially on shorter motors. I had to cut 8 inches off of a m90 to fit it in an rx7

Just taking your time with the TIG probably would have avoided the warping. You get in a hurry and you build a bunch of heat.
Exactly what I thought
Some serious booger welds. Just tack it on and seal it with JB weld.
I had a yamaha 3 wheeler the previously mangled the mounts on the head and lost the rubber manifold. It ended up a jb weld abomination and behold the oxygenated gasoline made the jbweld melt!!! 😅 so no jbweld is a real temporary solution once gas with clorinated ether hits it

M90 will always be the goat here in Australia 💪🏾🇦🇺
I always wondered how that would work out, waaay outside of left field on that one and over the highway! Right were my thinking goes! So damn cool to actually see this!
AussieSpeed makes a part that just bolts up a holley carb where the original throttle body mounts. Was looking at it the other day.
I ran that config too-if you watched the vid til the end-I showed you
My bad, I skimmed through it@@richardholdener1727
Wow. That's almost some Fury Road looking work right there. Immortan Joe would be proud of you😆. '' You shall ride eternal shiny and chrome.''
I had my silencer ports welded closed and suffered a very very small amount of warping also. The M90 sounds easy 2x as good now.
This is awesome! These tests are starting to seem more like Garage54
Rich you have one helluva fun job, I bet it doesn't even feel like work most of the time.

Running the carb as a blow through seems better, then you can use an intercooler as well. Or twin blowers.

I hope this guy's boss never finds out what he's been doing instead of working
wonder if you could just cnc a flange directly on the housing
nope
First 👍's up thank you for sharing 😊
If extra cases are abundant, could you test another carb top mount? Would a top rear mount achieve more airflow w/same pulley? (more rotor)
Attach 2 m90 superchargers from the 3.8L V6 thunderbird together and make them produce boost
Why oh why didnt you just use the factory inlet of the blower and make an adaptor plate to mount a holly ?
see the other video where we did just that-same power results
With today's cnc machines I don't think it would be to hard to machine the top of the blower to fit a carburetor adapter plate that would bolt on .
you can't machine the top for a carb-there isn't enough material
@richardholdener1727 ahh that... blows .lol
I expect it'd be better to have that massive hole closer to the end that originally had the inlet, especially at lower speed. Spiral rotors.

I also ran the carb entering the rear of the blower
I seen. I didn't check any numbers though.
Hey Richie, if it blows up, it’ll be a blow through blow thru!!

Not very practical for most applications. Would probably hit most firewalls

Did you weld it with the housing submerged in water and cut your hole after welding the adapter on?
It's actually not impossible to have a flush fit with this. Nowadays these tools have become more advanced than what they used to be.
I think Super Richie has gone Super sketchy with this one.

Not much squirter fuel pull over with this particular Holley.

would have been good if you put it in a mill have a flat for tapped holes and make the top port even bigger again
there isn't room or material for that
@@richardholdener1727 im hearing lack of skill and a mill its possible
Another awesome video Richard. I had a related idea for an experiment you could do for us. What happens when you use a carburetor and an elbow instead of a throttle body and injectors on an LS truck intake? Are the LS truck intake EFI top end power gains over a dual plane carb intake due to intake geometry, even fuel distribution, or something else? Can a carb on a truck intake make similar power on the same intake that normally uses port injection? Will it be way worse? I assume worse, but want to see this for science, and to hear your thoughts.
Fuel distribution becomes an issue based on other testing I’ve seen. I think it’s because the carb would be on one end and the air mixture has to wind around a fair bit.
Even with a dual plane it’s a pretty even and reasonably direct path.
I assume that since the plenum inlet is at the front, the back cylinders would run much leaner.
this kinda of stuff is fun.
It's sketchy and I like it 🤣🤣
Couldnt you just run it to the back openening. A lightning eaton m112 would of just been perfect for it. Inlets in top.
Did you watch til the end?
@richardholdener1727 my bad I should know better by now. 😂
How many miles are on the test junk yard engine?
100K plus
With the stock pully on the 5.3 you made more power but when you rested it on the 4.8 the first time you made less right what was different here
4.8 is short stroke, 5.3, 5.7, 6.0 and i believe even the 6.2 use the same stroke.
@shadowopsairman1583 yes all true nothing to do with my question but true
that was timing
Richie, how about making a AFrame style intake with a blower in each side? I suppose you could inverse that as well...... Though oiling could be an issue ....just an idea
already done
It would have been lean because the power valves wouldnt have opened.
With that little huffer pumping away furiously under the carb, the powervalve reference port in the baseplate of the carb would have been seeing much much higher vacuum than it would at WOT on an actual engine.
Also, is there any reason you didnt just weld a 4bb carb spacer straight to the blower housing? (Mill all the ribs iff first, and weld it straight on) perhaps welding two things of a more similar thickness/preheating the blower housing "might" have reduced distortion.
/probably not.
At least then youd have something someone could then fit to a car. As lol/click worthy that tall stack is, its not really very practical in the real world.
spacer won't work-vacuum was high at wot
@@richardholdener1727 need to externally reference the power valves with a boost signal. Id wager you must have a whole cupboard of boost modified carbs there?
Do you thnik its possible to flip the internal of the m90 to run on a ccw rotation honda engine?
Could you mount the SC backwards and then run a jackshaft? That would let the SC internals spin in the normal direction .
@@TheInsaneSheckladoryes it clould work but i try to keep it cheap and simple, i dont like the idea of adding moving parts and weight.. i heard that you can reverse rotation some eaton but only few of them..
just backside the belt
@@richardholdener1727 Belt slip? Or not a problem?
Looks pretty crazy
And I have a press u can use for the m90
What in God's name 😂😂 that's ridiculous. Add a salad bowl and nitrous plate next
every motors needs the bowl
