At 2:30, you can see the boost bypass valve is not fully closed, which is causing a large amount of boost to bleed off. The boost bypass valve is also not properly referenced, leave the lower vacuum line disconnected for this test. You can tell it is referenced incorrectly because when you let off the throttle, the flapper arm does not open. For the purpose of just running the engine on the dyno and not in a car, re-make the plate so that it does not have a passage for the bypass valve which will eliminate the variance in boost. Alternatively, you can also make sure the bypass valve is properly adjusted so that the arm is putting pressure on the set screw. You want the butterfly valve to be parallel with the supercharger. There's more to it than this, but for the sake of a short comment and just running an engine at WOT on a dyno, this will suffice.
I would like to see what the blower with a tiny pulley would do
I’d be happy to make him a custom pulley, I doubt the aftermarket ones available for the 3800 series are small enough for this application, but he will likely need to really tweak the routing to get maximum pulley wrap if going smaller. Makes me wonder why nobody runs a separate pulley and belt just for the blower, and run a cog belt like they used to, serpentine driven blowers making big boost are always fighting with slip... a cogged (toothed) belt solves the slippage.
Robert Ambrose the Saleen 4.6 2vs manage to get 390hp out of these
TexasRoadWarrior probably a combination of smaller blower pulley and larger crank pulley. I bet they are using every last bit of air you can manage from an m90
the pulley is actually large lol, dropping several pulley sizes would definitely help along with a different crank pulley
theres a aftermarket for the 3800 s/c setup so getting them wouldnt be hard
Jacob Burskey I doubt the aftermarket pulley options for the 3800 go small enough to make the kinda boost you need to feed an engine that flows twice as much as a 3800 but I’ve been wrong before. I know the 3800 guys still have trouble with belt slip when they up the power.
I too would like to see what an Eaton m122 off a gt500 could do on this same setup.
Or the 112 from the Terminator cobras
Definitely m122 gt500 blower. Twin m90s would be cool though
Seen lots of those set ups. They do well.
I have a MP112 which is the Eaton m112 head unit. Makes about another 100-150hp at 6psi depending on your set up.
imgur.com/a/jxNtd7L Just got it put together a while ago. It's an M122 on a 408 SBF.
Just got home from work. Poured a beverage... youtube notification. 17 minute video of Richard testing a blower that the internet says is rubbish on a V8. Life is good. ☺
That’s awesome, I actually thought about pulling junk yard blowers for ANY car and assumed it would make power. Never thought about the restriction of air flow. Great test!
How could you never think about the lack of air flow, ???
I’ve been really curious about doing something like this for a long time now I am so glad that you put this together!!! (Also yes you need to test the M 122 and a double setup!!)
"BOOM! We lost a bunch of power!"
You lost power because your not using the correct set up superchargers do not run on factory drive assemblies the crank pulley is too small and that supercharger pulley is way too big for a V8 application the Eaton M90 powered the rough mustangs to 400+ HP for years
@@patrickmonroe9062thought that was the m112 that did that?
@@patrickmonroe9062 mustangs used a bigger eaton supercharger. they used the m120, no the m90
Do a twin charged episode
I thought the same. Twin sc with slightly bigger pullies. Pretty sure I have seen that at a lemons race 😂
Ben Dodson smaller pulleys*
@@WS6xMASTER I was thinking larger since the SC was meant for a 3.8. Larger pullies would equal close to factory boost with the 3.8. Test it, then swap for smaller and see how much boost it will make.
Although, the 4.8 breathes better than a 3.8 so a larger pulley swap probably wouldn't be needed.
I have a 5.3 with twin m90s
Agreed, there is an actual benefit too dual blowers in that you dont need too spin them as hard too support the HP and that helps keep IAT's down. Would love too see the hard data
The supercharger Bypass was OPEN.
REMOVE the supercharger valve.
Plug to hole in the plate.
This M-90 will boost a 5.0 engine.
THANKS for all your hard work.
That has helped me.
THANKS
Something is likely wrong since these m90s make max boost by 2000 engine RPM and the starting power is below even the stock 3.8's 240. I don't think the displacement is what matters as much as the CFM. Go back to 2000 when GM was making these and the n/a 3.8s had higher power output than ford's 4.6 modular since the heads flow more.
Love the test !! I’d like to maybe a GT500 blower or terminator blower on the 4.8L though. Might make the ultimate 1/2-ton truck trouble free upgrade (we all love turbos, but we all should be able to admit that an roots blower with modest demands its generally more maint. Free)
The blower would make good low end torque for a truck. I'd want to sandwich a heat exchanger in there though.
You will eventually blow a spark plug out
Would love to see a twin M90 setup. Blown junkyard build up on the cheap! That would be super cool to see.
I am planning to do just this. Ive got a junkyard 302 out of an explorer going into a mercury mountaineer. Its the same motor, and the one already in the car has 1 m90 on it already. Hoping to make 400hp under 1k
Why would you even use them wimpy blowers for such a big engine....I bet you can make more HP with just a cam and headers and tune then you could with two of those wimpy things.....them little superchargers barely even bumped the horsepower up on the 3.8 V6.
I have seen it done and it looks awesome
Your videos are awesome! I would love to see a video with a smaller pulley and then a follow up with a 112 blower. I think gradually getting bigger and badder would be fun
That was definitely something I have always wanted to know owning a v6 supercharged engine before.
I’d say stock motor and stock blower. At this point let’s see a smaller pully since the motor has work keep it going.
Definitely go for the twin M90's. I had a friend when I worked at Eaton that put twin M90's on his Ford drag car in the late 1990's. It was a wild-looking thing. A single M90 on a 4.8L engine just can't supply enough air. You basically summed it up when you said the M90 was good for about 300 HP. The situation in this test would have been improved if you had just taken the belt off; then it would have made close to the NA power, with the supercharger windmilling in the breeze.
If you can get two M90 5th-Gen's with the coated rotors, that would be even better. The coated rotors improved efficiency that added 20 HP to the supercharged 3800. I tested M112's and M122's at Eaton a lot. M122's weren't much of a step up from M112's because the intake port was no larger. The TVS series was a HUGE jump in performance because of the large intake port and improved port timings.
I love your vids. All the different combos, and goofy concoctions, that I think about during the day.
So glad I watched till the end. I wanted to recommend the compound set up of a large turbo blowing into the m90, but I see you already thought of that. There used to be a Hellion kit for the Terminator Mustangs that added twins that blow into the stock SC. Sucks that the m90 is too small for this. I still think it would do good on a 4.3 in a rock buggy. Keep up the awesome work Richard!!!
I'd like to see you do this in stages to overcome this problem, smaller turbo wheel bigger crank wheel then if that doesn't work slap on a second m90 and go through the gauntlet again. Great content, looking forward to seeing how this one plays out
Would love too see what that m90 does with a smaller pulley(
Great episode once again! I always learn things from your videos!
Dr. Frankenstein I love watching you build your monsters. Build them all. Who knows one of your creations might surprise us all. Awesome stuff .
That intake still has longer runners than most supercharger manifolds! I like it
This was a cool test. Smaller pulley, twin superchargers. Was literally my first thought when the video started lol. I bet this engine could put down 580-620hp with two. Depending on pulley size. If you built a box design intake, you could even run three superchargers. One on top and one on each side. Would make a sweet looking rat rod engine.
Very cool swap and test Richard! I love this swap for power stuff, great idea!
You're nuts man...and I love it. Glad I found your channel after I saw you on MT Engine Masters.
Yes do more testing with the M90!
Your videos improve every time i watch them and the information is presented very nicely.
What about volumetric efficiency? Does this come into this test?
Overdrive that thing 50%+ and see what happends
Great content rich. Keep up the hard work!
I just found your channel. I love your videos. Thank you for making them. It's no wonder you have such a magnificent like/dislike ratio!
Welcome!
I would like to see this continue. Twins would be amazing just to see.
Would you be interested In letting me ship you a full stack intercooler a set of pulleys 3in and under and a way bigger throttle body with an adapter
Good god someone pin this comment!
^ This please!
👍👍👍👍
And add some race fuel + bigger size injector that combo ! 👆🏼
I’d be interested
My friend Bobby Calhoun has two M90's on his 1UZFE (4.0 quad cam). Seems like they move enough air, but this answers my question as to whether they're worth running a single or not. Haha
Thanks for the info, and quality entertainment! Keep up the good work man!
yep, keep going with this kind of tests Richard!
Thats badass backyard engineering! Even if didnt work...... forget twins and go w triplets for freaky lookin old skool effect!
Man I'd love to see a terminator cobra M112 blower on there or two!!! 🤘🇺🇲🦅
Rocketboyjerry those aren’t much bigger. The cobra motor is only 4.6 liter and revs to the moon
Just posted the same. Or a GT500 blower
@@BustedWalletGarage True but its for a v8 and flows more cfms than the one in the video. Plus you can port the termi blowers easily for a good bump in air flow. Worth a try!
Rocketboyjerry the gt 500 uses an expensive throttle body and needs an intercooler. By the time you fabracobbled all that together you could get a good used complete Procharger system. I think the point of this video is “ garbage in, garbage out “.
BustedWalletGarage for the $5,000 that “good used” system cost you could build a legit reliable turbo system. The point is, I can buy a GT500 blower right now for $300. I think they normally go for $750? $900? Idk about a $4100 throttle body.
I mean.... if I could buy a pro charger Complete (yea... more like supposed to be complete, but rarely is) used for $1500, that would be the deal.
Junkyard parts testing... Exactly what I would be doing with access to a Dyno 👍. Love it!
Thanks for doing the m90 ive always wondered how this would go.
1. Verify the lower pulley size on the 3800 V6, maybe this m90 wasn't spinning fast enough.
2. Definitely try a twin setup, guys will only do it if it works.
3. Give us the pricing numbers so when it does work we can make the cost analysis against an Ebay turbo.
Great content Richard, keep it up!
Reminded me of the late 90s and being on the Geocities site reading about Mike Sitar's thunderbird with twin Eatons! )
i like this concept, although i don't like the v6 throttle body used here. that is likely a restriction on the v8. this is something i would willingly attempt
@MrJohn613 Budget Builds I know a guy that put one of these on 3.0 V6 in a Dodge Shadow, stock injectors with a Vortech FMU for fuel, no timing adjustment at all and went in the 12s on slicks. I totally agree having a much bigger throttle body and porting the blower would help!
Www.toohighpsi.com
The website is still around.
@@lilsammywasapunkrock Yea, the difference is that Mike now works for Magnussen and the project car is his son's. For a while, he was an engineer for Eaton, and way back in the day his dad had a mustang with twin turbos off of the 2.3L fords while Mike had a bunch of different combinations (turbo and supercharged) in an 80's T-bird.
What about the high ram on just the spray?? That would be interesting to know what that power output is compared to n/a and blower, and blower&spray.
Here's what I would do: Smaller pulley until the belt slips because there isn't enough pulley for it to properly grip. Then maybe twins but if so with stock pulley size and then with the smaller ones. After all that, weigh it and figure out if the work is worth the weight as compared to a turbo set up with similar results if it actually makes more than the NA configuration. Awesome video! Thanks!
I would like to see the affects of water/meth injection on the some of the boosted applications (pre charger/post, intercooler/ pre ignition reduction. Air temps ect. )
The "Junkyard Dogg" channel is building a twin m90 5.0 in a fox body. Y'all should go check it out.
Love the channel man !
I just put a ford m90 on my Subaru, its pretty wicked on a 4 banger !
On a stock 3800 s/c (l67 engine code) the crank pulley size is 6.95 inches, Would love to see more tests done with a 3800 and to see some of the platforms myths busted too! plenty of interesting tests could be done but im not sure if the fan base here would be interested in seeing v6 stuff sadly.
They can make 600+ hp with a turbo for those semi curious
Hey my favorite engine finally came up in your videos! I build these 3800's as a hobby. They are very stout little fellas. Currently working on my own little turbo 3800 right now. Aiming for 700hp.
It'll blow up
@@snoopy5736 got a forged rotating assembly, oversized head studs, and a whole bunch of strengthened valvetrain parts. It's definitely not gonna blow up.
@@DeagledSmeagol Anything can be destroyed by the tune/r, get somebody competent to do it!
@@Aseutester I am a tuner. 😃 This is just one of my side projects. Current output is 600bhp on 18lbs of boost.
This one was particularly tricky as the MAF runs out at around 9lbs and there's no 2bar OS, so fueling after about 5000rpm has to be done with PE tables.
I would love to see a compound test. I have a 4.3 V6 with twin turbos compounded to an m90 drawing through a predator carb and does pretty good. I’m mixing race gas for about 102 octane. 18-20 lbs boost .haven’t had it on the dyno yet
All can be see on my page
I've been waiting for this test
Keep up these superb videos Rich.
Richard, try a Eaton TVS 1900 from a 2010 Jag V8 😁
See how far you can go to optimize the 1 m90, that's something no-one EVER shows
First saw you on those Engine Masters episodes & thought you were sufficiently knowledgeable (and just corny enough) to do your own channel, & boy was I right. I've had a youtube account for probably 15 years, and youre the 1st & only channel I've subscribed/bell'd/etc, just because youve got crazy content for free. Not that you asked, just wanted to share. & say thanks. So, thanks!
& to answer your question: do it. All of it. Smaller pulleys, ported blowers, better throttle bodies, TWIN BLOWN. Yes. Double Yes.
I really like your videos your doing a great job. Videos on different turbos (gt45, cx racing, summit junk yard turbos) and different cost effective boost controllers would be great.
Where's your ported LSA BOOST-O-MATIC? They are super cheap nowadays compared to buying a new one.
Richard, I’d love to see you max the m90 to see what power it will support. ZZP makes a lot of pulleys
Hittman1422, without porting, chasing power will be a battle between boost and heat. More so, to the point of where the M90 is efficient. M122 is where takes over where the m90 maxes out to and does so more efficiently without the heat the M90 generates.
I was thinking of doing the same project you have just done. However I have a M90 Roush supercharger from an F150 with a 5.4. Any thoughts?
I’d love to see two super chargers , I love to see straight junk yard stuff being used.
I vote more testing with the m90. At least see if theres any gains to be had.
Id like to see a stiegemeier stage iv ported m112 on there!
Richard, Thanks for your videos very interesting, I think two m90 Will be Better just look to solve belt slip
I put a m90 on a jeep wrangler 4.0. With that in line with 5.5 pounds of boost. It was a beast. M90 works awesome on jeeps inline. Just won't unless modified on 05 an 06. Anything below a 05 the m90 is a beast
I’d like to see the m112 off the lightning then the M122 all on the same motor individual testing then dual M90 blowers. Like junkyard dog is doing to his 5.0
That would be cool, but your not finding those blowers in the junkyard lol.
allanb3222 right but the M112 you can pick up for 450-500$ and the M122 you can get for 650-700$ which is relatively cheap compared to a Weiand.
And the people who would be interested in making one of these blowers work would most likely be able to fab up a lower intake and or do like B&M back in the day and make a plate to bolt to a 4150 flange then to a blower bottom plate.
@@allanb3222
M90 are in pick & pull yards
@@nellyfarnsworth7381 yeah but not m112 or m122, like he is wanting.
The blower was probably wore out. Remember when david freiburger dynoed the blue impala with the blown crusher camaro engine at westech. He went smaller and smaller on pulleys with little to no gain in boost
I'm surprised it didnt make any boost. I'm guessing the 4.8 consumed all the air before any positive pressure could be made/used?
Hi i saw your jetta hybrid project that was a nice work!
Interesting! I have 3800 that was superchargered and i pulled blower apart and blocked it off and slapped a turbo on it... 3800 loves turbos... aint no ls but its ok
Use BOTH
Supercharger and TURBO.
It works.
Drove a 8v-92 Detroit Diesel, the the FACTORY made.
The TURBO blew into the supercharger. TWO CYCLE DETROIT DIESELS MOVE ALOT OF AIR.

Loved my 3800 Grand Prix even stock
Would love to see the compound setup with a turbo blowing into the m90, been thinking of trying this myself
Not efficient, the m90 is a choking it at that point
I may just do it this spring. Already have a ported m90 on my car, and a cheap 50/60 turbocharger lying around.. but turbo would be mounted in the trunk. Im doing a mod that requires the spare tire well to be cutout, so would be quick & simple!
Zenithskull mine is not an Ls it is a 3.8l l67, and it’s not stock ,2.7”pulley ported blower and heads cam etc and made 400+ rwhp ran best of 10.88 @ 122 so blower is pretty much maxed
Can you redo this with a smaller pulley?
Or try a gt500 m122 blower?
Hi good show. I like to knw what would you recommend for 03 stock suburban 5.3 flex fuel ls ?
Curious, many years ago people ran Eaton blowers on Rover V8s, genetically related to the 3.8 in the big picture, but anyway, there were issues with fuel distribution and I wonder if those rear cylinders are getting less than those closer to the opening. Any indication of this due to the orientation of the fitment even if you used a larger blower?
I'd guess since it wasn't able to make boost there's little restriction to where the air is going, only from where it comes.
Rover V8s are essentially Buick 215 V8s. Theyre super small so it makes sense on that application.
I'd like to see the 2 m90s, you can use the alternator in between to get good wrap on the 2 blowers.
Since cfm is dependent on rpm, and this blower doesn’t flow enough cfm to support big hp numbers upstairs, can you optimize this setup for low rpm power? 7,000 rpm power is moot for trail jeeps , but sub-3500 power is king. Maybe the factory cam, a heater core intercooler, and a tiny pulley?
How much timing do you typically pull per pound of boost on pump gas (93)?
I'd try twin M90s before getting into the trick parts. It's pretty obvious it's way too small... but let's spin it until it blows up lol
The "Junkyard Dogg" channel is building a twin m90 5.0 in a fox body. Youl should go check it out.
They can spin 16k rpm reliably, past that they are just inefficient, but I've seen as high as 20k rpm before they grenade lol.
It'd be hella cool lookin' too
The only reason it is seeming too small is due to the 3.8 inch pulley. The 3rd gen m90 blower reaches 90% volumetric efficiency at about 12k~rpm blower speed. Assuming his stock crank pulley is similar to that of a 3800(about 7.5 inches) he's under a 2:1 pulley ratio. That means the blower didn't even reach peak case efficiency until nearly 6000 engine rpm. The benefit to a small roots blower is its ability to turn more Rpm. Take into account that this same blower has put a 3700lb fwd car into the 10s. I think if it were to drop pulleys down to a 2.8, he could get enough volume of air to pass 400 crank hp with no issues. These have supported 400 whp in fwd auto combos aswell and he could throw an ati super damper and pick up even more blower speed. Also this combo could retain an alternator with zzps 100$ belt wrap kit that would keep tension for the blower and alternator both.
@@madmod regardless of that cars' weight, what engine was it? Even with pulley swaps, the M90 can only produce a certain amount of air. The faster you spin the blower, the greater the amount of heat produced which will ultimately cost power.
lets see an eaton m112 off a mustang. very similar unit but displaces more air.
I love these experiments, junkyard goodies and backyard engineering. Try compounding two m90s stacked up for a parasitic 570ish HP.
"Makes me wonder what would happen with two superchargers... But that's a test for another day" *quickly searches through the videos for that test*
I'd imagine that the 4.8L can breath more air than the M90 is able to push into it. Would be interesting to see a M112 or M122 off the Ford Lighting / Mustang GT500 would do on a 4.8-5.3L. Would be interesting to see if they are efficient enough to actually produce some boost.
He ran that test, did you watch it?

Back when I was in high school I really wanted to put a m90 on a 4.3 s10. Never happened.

@@bluenecross It's been done, the intake is the issue since the firewall is in the way
Would like to see m90 on a 2.8-3.1 v6. Those cavalier z24 60 degree heads have canted valves like a big block.
Im currently fitting 2 gen 5 m90's to my Z31. Slowly....
I'd like to see more videos on this with different size pulleys and maybe some form of intercooling.
Right now I'm torn between welding up a full intake with inbeded intercoolers, but I'm not sure if I can weld aluminum good enough for that yet. Or having the sc's hover slightly above a low profile plenum and have the boost be collected at the base of each sc and sent through a fmic.
I was ok with old school chevy 350s i knew how to get power but now i am trying to learn the LS stuff and it seems like i am starting all over again.I like your show it has the best info on the internet .I would like to see how you would put 2 blowers on that motor
I'd like to see it tested again with a gen v m90 and the smallest pulley available
yes and a v8 throttle body. that v6 throttle body is so small likely restrictive
ZZP recommended the northstar throttle body for higher performance 3800's. Still seems a little small to me when you're starting point is 375hp.
@@s1mph0ny the Gen 5 is already a 75mm inlet, so the Northstar isn't an upgrade on a Gen 5. Porting the hell out of the inlet and adapting an LS throttle body would be cool to see, though.
Confirm that your superchargers actually spinning at the correct speed before you make an assumption you didn't even know what the pulley size was for a stock 3.8 L V6 on the crank what is kind of important determine the RPM of the supercharger
I always wanted to run a whipple blower on my 3800. With a Gen V m90 I managed a little over 420fwhp in my Bonneville but a whipple would have been crazy.
I see this being a new episode of engine masters soon! 🤭
Whats going on with the plenum floor at 5:00 minutes? The front 4 runner are covered in oil. Blower puking oil? Maybe run your headers with 8 O2 sensors and see what air distribution looks like if the oil stain is any indication of where the flow is travelling.
typical of the blower-the discharge of a roots blower is always offset to front or back-oil residue might indicate something
@@richardholdener1727Just a guess here - With the motor pulling more air than the blower can supply (as the dyno runs showed) the plenum goes into a vacuum state and pulls oil past the seals of the M90. Now the 4 oily runners could be that the oil is heavier than air and doesn't want to do a 90 degree turn to the rear runners. Or is it so choked down that the air is just following the path of least resistance from the M90 outlet to the front half of the plenum. Maybe have a look at the plugs and see if anything was leaned out. Keep up the great work.
There's a CZcams guy, junkyard dog I think is his channel, that put twin m90s on a Ford Pushrod 5.0
I saw his stuff-cool
I gotta check that out!
not running as far as i can tell, btw i subscribed.
@@richardholdener1727 since you mention it, that does seem like a lot of work instead of a big cheap china turbsky
Was that in the Thunderbird? I remember that and there others who ran M90s on 5.0L fords.
Off the top of my head, a 3.8 l67 crank pulley is 7% smaller than a LS truck pulley. FWIW, my twin 5.3 will see 5psi at idle with the bypasses shut. 15-16 under full throttle. Also what gen blower do you have? That will make a difference.
Throwing my hat the M122 test hopeful. The 2007-2009 supercharged mustangs are rated at 500-600 hp!
Beating the air by Spinnin’ it waaaay up just adds a ton of heat.
Watch out guys, Captain Obvious just arrived
Yeah this setup needs an intercooler
Do twin superchargers plus twin turbo for all the boost!! :D
You might be disappointed. Often when you combine turbos with a positive displacement supercharger the supercharger gets you quick spooling from the turbos but the supercharger becomes a restriction at high rpm/boost.
@@177SCmaro I knew that but never saw results of the combinatio.
I was interested in spool and how badly would supercharger fail in high rpm hahah
Matej Šimek I have that set up on a 4.3 V6 and it works well
@@gotmilke1 hmmm
What is the peak rpm of the engine?
Matej Šimek rev limiter set at 6,000 but mostly drive it below 5,000 I try to be conscious of that because I’m worried about breaking the crank (4.3V6) turbos make 8 lbs combined 18-20 lbs
Better than cable tv! Thanks guys.
I have an LG4 305 that came factory in my 85 Monte. And I also have a 2004 Impala SS with this same supercharger. Question is, if someone were to fab up an intake with port injection that would allow this supercharger to be mounted on a gen1 305 with smog era heads, would it make boost or is the 305 still too big for this supercharger?
if you spun it real fast it might work-better to use a different one
Gtp my first hotrod Lmfaooooo
I’d take it off the ls and put it on a 2.2L ecotech 😋
That makes entirely too much sense

What power does it make without the m90 and the same wet fogger just curious
Yes keep doing m90 testing. I have seen truck guys do a dual setup
Why couldn’t you run a smaller pulley spend the supercharger faster
Because out of the efficient range. These blowers are 54% at best
why would you do a m90 when there's a ton of m122s for 500 or less that are actually made for a v8
@Pizza baller there's companys that make them for m122s, tvs1900s, tvs2300s
id go tvs 1900. you can get gen 4 rec port to cathedral port adapters for like 200-250. m122 plates are 1300-1400 and the tvs1900 is better then a m122
awesome test keep these weird tests coming
You had my hopes up for a minute.
