- The twin Eaton's finally made it on top of the engine over the last week or so, so before we go any further and start putting all of the wiring, brake lines, and fuel lines back into the car, i want to make sure this thing runs. Hooked up a fuel line, coil wire , and jumped the starter solenoid, and well.... it fired!
Its projects like this I want to be doing as I get the experience. Beautiful work. This is really inspiring to me as a young mechanic, showing me the possibilities of hard work and imagination.
Same here and I saw an 81' Firebird for sale that has a V6 and then an M90 Supercharger in another ad and this vid has got me thinking about putting the M90 on the Firebird and get the electronics from an 02' Pontiac that can with a factory installed M90 supercharger and stick it in that Firebird should I ever get enough money to buy it before it's sold
I LOVE IT! You fabbed something WAY cooler than you could ever buy! Great work!
That intake is nuts. Interesting work.
Your fabrication skills are killer!
Use an idler pulley from a Cadillac with a 4.9 v8. Used in like a 92 Seville. The pulleys have a ridge on the sides to help with belt tracking.
It's a Chevy, I've seen some crazy stuff done to them, there like a old dog, they love to please there owners. Killer looking setup! Keep up the good work.
WOW , that is one amazing motor. Well done. I love the look of it. You did a great job
Ive been wanting to do this myself for YEARS!!!! THANK YOU
You had me at mad max car....subscribed!!!!
Great job. I had my doubts it would run that well with the design of carb adapter to supercharger but seems okay at idle.
That plenum seems to feed the blowers well.
Love this sort of stuff!!! I run a tiny eaton m45 fed by a garret gt2871 turbo in full compound configuration on my 4ag powered aw11 mr2. It's awesome fun to drive.
I have a m90 that I will be putting on my holden rodeo 4wd, it has the 3.6 alloytec engine.
Blower whine, the best whine there is!
Wow that’s awesome......I’m guessing with a tune and fixing the pulley maybe 11 pounds of boosts. Just weld a washer on the pulley and your good to go. It looks awesome very nice build.
This is mental!! I love it!! I’ve just decided on my new project!
Great video.
I don't speak English so much by the motor in the car 2 super chingon. Mucho bueno👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Good looking power plant.
Most beautiful supercharger whine ever 😍
Never to much boost,just have to keep it sealed and correct air fuel management 👌 😎 and some robust interals,intervals, a very conservative tune,lol,nice little build,I love home grown projects.
4:24 The BEST procedure, is a squeeze bulb and gasoline hose, on the carburetor VENT TUBE, to push gasoline into the carburetor fuel bowl.
I wonder how much horsepower at 6 lbs of boost it adds to your engine. Definitely enough boost to feel something with the seat of your pants. Or butt Dyno as some prefer to call it. Lol. But love how it looks with the carb cover and everything. Looks F-N awesome
You’re my hero. This is awesome.
Now this is the type of content I like.
Fine piece of carrying on!
It looks beautiful !
Like Dr. Frankenstein said "IT'S ALIVE"!!! You might want to get some idler pulleys with flanges on either side to keep the belt from walking off sideways. I bet the blowers could build enough pressure to blow the head gaskets out but I have a feeling that carb won't flow anywhere near the CFM's you're gonna need to produce the full power the twin blowers could produce. The blowers can build pressure but if they are restricted on the intake side the blowers will starve for air and they will be trying to pressurize air they don't have. Looking at it only from the perspective of boost misses the aspect of total cfm through the entire motor from the air cleaner out the exhaust. The motor is just a big air pump and you could spin it with an electric motor without any fuel or ignition and just measure the total amount of air it can move in CFM. If it can move x amount of air without the carb and less with it then the carb is restricting the whole system. You might want to go to 2 carbs with one for each blower.
Awesome video mate, subscribed , just finishing our own supercharger build
Those superchargers are made for v6 grandprix gtp so you will need 2 of them to get decent boost. I think the 3.8 supercharged was a 231 cubic inch engine. I might be wrong but it looks great cant wait to see it do a burnout. And maybe a 0 to 60.
Cool build! Congrats on her firing right up!
Very Cool setup ... you should Line-x the whole car !!
You need to get back idlers with the side lips too help keep your belt on. That thing looks awesome.
Good work
Oh and one more question ....are you worried about the fuel washing out the internal bearings on the m90 ...either way
..this thing is cool as hell
This has to be in a next mad max movie
My 2nd favorite "pair" next to my GF's. But I wager yours might just be more fun.
I have two right now, I can only imagine a 305 built with efi n two of these. And yes I’m collecting them of them gtp’s😂
Dude...that is sick cool. My hat is off. Looks and sounds demented. I'm already wondering if I could do this on my lq9. Whew, that whine. Swoon. That is just so frikkin cool.
Looks great but tensioner goes on slack side not pull side
Great job sounds good ,from down here in on da bayou
NICE !!!!!!!! might need a cage to keep from twisting up the body ; like I did to my vega years ago .
drivers door was popped open and up about 3" at rear opp's hee hee
5:35 You had a real look of surprise on your face when you stared at the engine for a second believing it was gonna stall but was idling smoothly instead!
That is badass, good job!
I have an Eaton M90 off a 2000 Pontiac Gran Prix I'm looking to fab up for my Jeep 258. I see you did a draw thru setup which is how I'm looking to configure mine. I was planning on welding up a small plenum adapter to go from my Weber 38 to the blower and into the intake. A lot of people advise against draw thru but that's my only option short of fuel injecting it. Any tips or pointers? How did you set the vaccum up? Did you use breather vents or actually plumb some hose in? Thank you! Awesome build by the way...It's not everyday you see two blowers custom fabbed like that!
I used a regular chevy valve cover pcv valve to do my crank case venting. The blowers were welded up to basically be just blowers. Tips..... Not really, all depends on the application, just keep your base plate heavy and flat and the rest of the connections just need to be welded good and sealed tight
That's bad ass!
I'd say well done man.
Looks like a mad max car
That's freaking amazing!
So cool!
Amazing! Great job! Can't wait to see it on the street.
You are my idol sir !!! Couple of questions for ya ...was that a vacuum secondary carb ?? What CFM did you go with ?? And did you junkyard find the tensioners ?? Amazing build ..I've always wanted to slap some m90s on my carbd foxbody
6 psi is expected with stock pulleys. Go to a 3.4 inch and run 93 octane with a bottle of booster every tank. Will get you around 9 psi.
just space the idler pulley out so the belt runs more on the flat part of the pulley
Hi, did you boost reference your power valves? Ray Soto here on youtube did a similar conversion, He put a Jaguar supercharger on a small cube olds. He has a video on boost referencing the Carter / Edelbrock carb. He is running draw through like you. He said that he blew some stuff up before he figured out the boost referencing. You might find it interesting. He is very willing to talk about it. Hope it helps !!
That’s awesome
Please tell me that you’d sell me one of those intake manifolds
Get rid of the spring tensioner..it's on the pulling side.. wrong side..use a stationary adjustable tensioner..
Pulls safety catches while under lift then puts arm across top of carburetor after a possible "kickback" but need safety glasses in case the belt breaks. 🤔 Awesome project but lots of what not to do here. Keep up the killer fab work but please put your own safety higher on the list!
I also removed all the guards from my grinders, run the old Mill with a wide open 3 inch bell slapping around out back, and go behind the old Niagra shear while it's running . Hell, occasionally I stand on the top rung of a ladder too... Both latches need to be pulled to let the hoist down, they shouldn't have put them under there in the first place when they made the hoist, and if you ain't never been torched by a carb a little bit you ain't no mechanic. Worry about your own bobber bud, I got this. When I hurt myself you can tell me ya told me so. Thanks for watching!
@@rottersgarage I'd just hate to see something happen to such an innovative DIYer
You are using flat belts and you cannot guarantee that all the pulley surfaces and axes are true. Do what the Victorian engineers did with their line shafts and pulleys, machine a gentle dome on each pulley. Flat belts always run up hill, when they get to the top there is nowhere to go except stay there. No keeper plates required. not the same as timing belts. It goes without saying that accuracy in alignment will help. If you use domes and the belts fall off then look at the alignment. You have the expertise to build a test rig.
Thoroughly enjoyed your videos, I would like to see the Model A make progress to restoration.
Brotha THATS WILD
And also watch out welding a washer to that pully it may stop the belt from coming off but it may tear up the side of the belt and break it off anyway. So buy alot of belts lol.
Hell yea!
Your a 1/4 of the way there. Just 6 more super chargers.
I want to do this with 2 ported m112s and a six pack on top of a mail box between the inlets
shim that pulley about 1/4 and forget about it. nice car!
That's fucking awesome damn great freaking job bud cheers
Excelente información
Is there no bipass valves being used on these M90s? I love the imagination and initiative that went into making this.
I can't quite tell from this video, but how open is the air plenum that the carb is mounted to? I'm gonna have to watch the build videos lol
There are no bypasses. Years before i started this build i had gotten the superchargers, put them in my bandsaw, and cut them off right at the throttle body. The bypass ports were still there, but i did seal them off in one of the build videos. I appreciate the comment, it got cold up here and we are currently focusing on ice racing which will be starting in a week or two. Will most likely pick up with this project in spring when the temps go back up. Need to do some major jetting and a carb swap to make this thing right....
Also, the plenum from the carb to the blowers is wide open inside. Just a box from the barrels to the blowers, same with the intake plenum under the superchargers.
@@rottersgarage I just watched part 4 and caught all of that haha. Certainly is an awesome project. I had to do some modifications to the inlet of a cnc ported M90 to make work for the 3800 in my 2002 Pontiac Firebird. It turned out pretty good I must say lol. Everyone of course hassled me about LS swapping it because that's what f-body cars should have in them (and I would agree) but I wanted to try and have some fun and be different. The power to weight ratio of my car right now is about the same as one with a stock LS1 in it. I can easily keep up. I've actually pulled away from a 2010 Camaro that had a stock LS3, but those gen 5 cars are 1000 pounds heavier.
I’m doing this!!
sick
Just saw this in a burnout competition, would like to see more! update us on the build.
Soon I'll get another video up, Indy was kind of a flop but a great time, had fuel problems and basically drained the front bowl after the first 3 roundy rounds, oh well we'll get her figured out! Updates soon....
3 years ago? I've been waiting 5
Awesome!
Use a tensioner pully with a belt guid on it
Wow
Hell ya
After seeing the aston martin vantage v550 i started thinking how would this be on a coyote? Ngl i want to do a project like that.
Course it fired up only macking 6P.S in it
Good job, I wonder if using a m122h supercharger would be simpler instead of trying to route the belt around two m90 superchargers. Although the m122h is basically the same supercharger used on the Mustang GT500. I cannot remember the supercharger displacement of a m122h or what the combined displacement of two m90 superchargers.
Iv been wondering this same question. Yrs ago I made a twin m90 set up for my rx7 and I loved it but ended up selling the kit and now I miss the insta tq and I'm seriously debating a m112 set up but doubtful it flows enough.
i know this comment is old but the eaton superchargers had their displacement in their name. the the number after the m is how many cubic inches of displacement. m62 (62 ci) m90 (90 ci) m112 (112 ci) so on and so forth. thought it'd be nice to mention this for anyone else seeing this in the future.
How do I contact you to get work done on my vehicle. ?
Updates on the twin super
This is awesome !
I just got done putting one M90 on my Subaru 2.5L Check out the build if you get a chance.
Drop a link
I'll check it out.
I'm surprised you didnt mount a carb at the back over each blower inlet for a simpler inlet
I actually considered it. Had two big bore rockchesters mocked up on it at one point. Decided to go with the 4 barrel just to make it centered out and more easy to tune in the long run. Fab wise I'd say it was probably about the same amount of work considering you would have to do two separate inlets and have two separate carb mounting plates....
Needs to be mpfi, would make it much better
Can you talk about your carb set up, type, size. I’m doing dual m90s on a 351w. In the fence to do carb or Try to use pro flo 4 efi
Kurt, currently have a 750 double pumper on it, blocked off power valves and jetted up. Don't really care for it and my fuel system is too small... I'm thinking Holley sniper kit this spring, would like to take it to cleetus and cars again....
how is this project going, might want to switch the tentioner with the idler pulley, the crank naturally wants to pull down on the blowers , so a idler on the driver side will keep it tight.
Project is going good, currently wiring it right now as we speak.... Got the tensioner working good. Didnt move it, added washers on the first idler pulley. Seems fine, havent jumped the belt yet.... I will have a new video on it in a few days.
@@rottersgarage back before there was android and cell phones with cameras in them i built a duel m90 5.0 engine, used a peace of 3 inch square stock for the top manifold with some 45* angles and all that. then hooked up secondary injectors on a switch for the added fuel for the blowers. worked awesome on WOT lol then boom
Hi mate, I’ve a Jaguar XF 4.2 supercharged, about 420bhp as standard, been told I can get 490 max with a smaller pulley and a remap..
Maybe I’m mental I don’t know but think it’s possible to have 2 of the chargers it currently has ? My aim is 550bhp - 650bhp, everyone just says 490 bhp max but I don’t believe that, car feels like it can do a lot more
Cant you just machine a wider pulley and make it lipped? Maybe get custom wider pullers all over, bar the blowers that already have them, with lips. Wont take much to machine a few pulleys out of a piece of 4" billet bar stock. Pretty fucken cool bit of kit though mate, whish we could make shit like this in Australia. Well, we could make it; but never expect to actually drive it around with the nanny state we live have to live with.
I ended up Tig welding some plasma cut washers out of 18ga steel on the pulley and it has been working out great. Ran er over 7000 rpm and the belt has not launched yet! A little quicker than the custom billet pulley idea, but it was effective.... But now that you say it, solid aluminum idlers would look great on the setup....
@@rottersgarage It would look good, yes. However, your are dead right and I was complicating the shit out of the whole deal. If you can run that set up at seven grand and it holds fine, thhen you have done a fantastic job. I'm a fitter/turner and the machining parts instinct is hard to break. Fantastic project, I need to go and watch the rest of the series you have now.
How are the chargers holding up running fuel through them, i want to do a junkyard 112 charger on my sbc.
You need to run smaller pulleys once you get the bugs out
How much to build me a intake manifold?
Dont worry its just blower surge
Legit
Your tensioner is on the wrong side never put your tensioner on the pulling side of the belt
Why not run dual carbs?
It sounds like the starter keeps runnin' the whole time.
what kind of hp did you accomplish, been trying to find a way to supercharge my vg30 on my 88 N/A nissan 300zx so i can keep my headers, but a single m90 won't get more than 240-260hp
Never dynoed the thing, but from what my engine guy figures, and what a few people have figured in the comments, 10lbs of boost in a 5.7 l should be making somewhere around 600 to 650..... Now I broke the darn thing but one day when the engine is fixed we might have to take it to a dyno....
Is it a modified crossfire, with a plate?
Can ya weld some flanges on the idler?
I did, and it worked! Yeah that solved the problem. 👍
@@rottersgarage right on, new to channel! Thinkin of an m90 on a ford 200… gotta do something to get air in there ;)
Its a beast!!
MIN 07:06 the gasket is takin air
Make me a intake for a ls
i just subscribed to your channel and i have a question whats hei mean
HEI is the GM distributor used in the engine. Stands for high energy ignition. The ignition coil is located in the cap of the distributor instead of external.....
