M90 on a 454....yes please!!!

Man, makes me miss my Regal GS. Everyone runs the same LS set up these days. Gets suuuuuuuuuper old.

Yes, regardless of an engine's size it's power output is directly related to the amount of air it can process.

I remember when they told my 1.5l Ken e bell wouldn’t make more than 400 rwhp on my 4.64v yet here I am close to 600 rwhp the inlet restriction was the culprit on the early 96-98 cobra kenne bell kits. I re fabricated the inlet and boost went from 9 to 14 psi that was a huge restriction

thanks you for super high quality contents 👍🏻

Love it or hate it, the M90 is still a tough little boost beast ! With little more than a 3.4” pulley and cold air induction, my L67 V-6 responded with a very noticeable increase in torque by blowing the tires off sooner and longer compared to stock trim 🏁

The thought of an M-90 on a 454 has me thinking 🤔 Maybe this is the way I go instead of an LS motor with a turbo. I’m not looking for high rpm’s, just low speed grunt with some get up and go when I want it in a 6,000lb truck with 33” or 35” tall tires (haven’t decided which yet). Love everything you do sir! Keep up the awesome content

Could you put an m90 blower onto a 4200? If so I would absolutely love to see how and what kind of gains could be made. I think it could be an amazingly cheap and fun junkyard option. Although I think a centrifugal supercharger on a 4200 would be the holy grail of power, fun, and reliability.

M90 on a 4.3

I'd like to see the M90 tested on the 5.9 Magnum. We kind of know what to expect, but I think it would still be fun.

Great video, lots of words though, my question is how much power will thus add to my stock 2012 silverado.

Great video

AWSOME video

I like this video.

I problem I have with this video is most of these stated issues are not myths. Just quickly looking at the M90's compressor efficiency map shows that this super charger is indeed designed to operate most efficiently at relatively low mass flow rates. To get this thing to work at the ~650hp range you're trading over 17% compressor efficiency, which is expressed largely as heat, an awful lot of heat and wasted shaft power. Also, likely running the m90 at its max operating RPM. It works sure, but in every regard its far from ideal. Considering the time, money and effort to install and tune this setup its nothing more than a meme IMO.

I'd like to see what the SC14, you can buy one new for like $300 and its the same size as the m90

Richard I always tell you I want to adapt my Eaton supercharger M90 on a 2.3 l Lima engine that they put in a Ford Pintos

id like to try one on my Boxster see what it does i think the sound would be frikkin awesome.... er

Im trying to get Accufab to make me a custom 3 bolt LS1 TB. I have a 75mm one now but bought a 85mm Holley for my m90.

I REALLY REALLY want to see someone run one of these on a Pentastar.

the best part is the torque increase.

Hey I have a great video idea for you! Do a video on “torque boosters”, adding a wastegate to control a centrifugal blower. Do tests like different WG sizes 38/40/45/50mm. Difference in boost curves compared to a normal pulley combo. Adding the WG before or after the intercooler.

Hey Richard! Did you ever get your SC truck running right?

How about that same supercharger on a "destroyed" 400 SBC?? Let's say a 372, 377, or a 352 (400 with a 327 crank).

Still waiting on the m90 of a 2v non pi 4.6 video 👀 why doesn't anyone make a manifold for this 😭

In a future video could you try an asymmetrical turbo setup on the 3800 or 4.3 V6 like Saab used on the 9-5. I have always been curious what the dyno results would be for such a setup.

Put one on a 6.8l v10 😊

Hey Rich… I had a sbc 383 built in a 1991 Camaro with a Holley 650 with vortex 202 heads. I was told it made 450-500 hp but it feels like less than the 305 that it replaces. Please advise.

My shop teacher has a m90 on a sbc I think a 305 or 350

Hello Richard, I have a question. I have 550 lift valve springs and recently upgraded to another camshaft with a 595 lift would I need to replace the 550 lift springs for some 600 lift? Thank you

I wish I was ready to do an upgrade my supercharger on my 04 Lightning, just waiting on parts, I’d love to send you my m112 for free, to see what you would get out of it. Bought it new less than 40k on the odometer.

It would put a big boost on my Sirocco

Dual M90’s!!! Haha, it would be cool to see but probably not very effective.

can you do a video like this for the Eaton M112. I can't find where u did any videos on the M112

I want to see a M122 go though all these tests. Even remote mounted with a air to air intercooler. They are still fairly cheap considering.

Hey Richard, what do you think the differences of bolting a gen 3 m90 vs a gen v?

I love my m90 on my 04 Dale Jr Monte Carlo SS L67 3800

I just got my truck Norris cam in for my 6.0, what heads would you recommend I go with?

Richard if you don't mind I've sifted through the 5.0 videos here and other KZfaq videos and I'm still not sure, at the moment I'm installing an explorer intake and new shorty headers I'm contemplating a cam upgrade while it's apart, I have a stock 95 HO 5 speed what cam would you install now that will work good with just the intake and shortys but will work well with a future head upgrade like afr 165s or the new SVE 170s. 2.73 gears now but switching to 3.55s, it's my warm weather daily and just want more more than the underwhelming 215hp while still having decent drivability. I have had several cammed daily drivers in the past so that's not an issue. Any input would be appreciated.

We need a dual m90 454 on a dyno.

You can put a bigger impeller in it and make some good numbers

Used to call them hair dryers on my Thunderbirds

Here's another one I thought about. A Japanese V8! How about the VK 56?

Whatever ended up being the problem with the 5.3 that wouldn't perform well on the dyno with this M90 blower IIRC.

I'm curious to see what the M90 does on a motor that's smaller but more efficient than the 3800. Like maybe a K24, or a J-series V6.

Hey Richard, there has been rumors around that they’re no longer filming engine masters. Do you have any insight whether that’s true and if so what’s the reason? Thanks!

So, if you’re looking to cool the air through the intake, could you fabricate a intake system utilizing an AC pump so that the cold air is introduced to the intake, or would the cost of turning the AC pump negate any gain? Just thinking out of the box.

So what your telling is that when my mates are saying forget about a junkyard m90, it's useless, they are as silly as I was thinking when I heard them say that? lol. Maybe one would be fun on my little GMH 253ci v8 after all.

Is there any way to figure out the pulley ratio for a certain boost amount, like 7-9 on a 420 inch engine? And I’m going from a v belt to a serpentine belt via a jack shaft somewhere in the middle so there’s plenty of room for adjustment.

Could you put it on a 10:1 compression ratio small block Chevy 350

I'm still waiting for the 3800 big bang lol

Can you put a clutch or similar onto a supercharger in order to run NA at low throttle but initiate boost at a preferred rpm?

So if you put the M90 on a 650hp n/a motor, that should be at the maximum airflow of the M90 and we should see no boost and no hp gain? Right?

Could you put the m112 on a 3800? I'm wanting to swap my fiero and curious what benefit it will make

Agree with most of this with one caveat. The idea that putting it on a bigger motor is even better (less boost, more efficiency, less heating) works until you reach a blower speed limit. This M90 on a 492 for example, would have to spin 3x engine speed just to break into positive manifold pressure at WOT. At 6500 rpm engine speed you're already near 20k rpm blower speed and I'd wager you would be hard pressed to see gains spinning much faster. For PD blowers I like to see engine to blower displacement ratios in the 2:1-3:1 range. OEMs have and do go higher (LT4 is 3.65 and the LSA is 3.25) but they're usually more concerned about low end fill. Ford and Dodge are down in the 1.9-2.3 range and they have 1000+ hp potential on the stock blowers.

when are you doing the big bang

Do they make the intake adapter it run a M90 on a Ls3? Or did you make the adapter?

I'm still waiting on the m90 play adapter to become available

Does the blowet have less loss on the v8 because of the boost difference and how much do you think

Use two.

How would I be able to use one on a sbc 350? What all would be needed?

What was the problem with your truck with a m 90 ? It didn’t make power

How does it go on a smaller engine, say a 120ci straight six?

I am about to take my m90 off my supercoupe its been modified and rebuilt by magnum power if anyone is interested in let me know im going to do a turbo swap

I still think the TVs 1320 would be a better option than the m90 it’s a little bigger and more efficient at higher rpm’s and can be had for the same price as an m90

Can you run it draw through carb?

How much power can it make on a k24 Honda ?????

If only these were compatible with magnum/hemi

Didn't you basically create these myths in your original video corking the engine?

Will a centrifigul blower sized for a 4cyl K series engine make 500hp on an LS motor?

Keep in mind... Thats a 200$ blower..

nothing physicly stopping you. pushing it way outside its efficiency envelope with more speed is going to make low density hot air, still gonna get a boost number but not the power. engines don't run on pressure psi but air density lb/ft^3. air density takes into account everything including tempature and you can compare supercharger sizes and everything directly without being wacky about it.

hear me out m90 on 8.1

Thank you for your knowledge and videos USA 🇺🇸 TRUMP

so... can you do something stupid with these m90's and like... stick it on a chevy I4 from like a chevy sonic ? or cruze ?

Stop using the same colors for different configurations on your graphs!!!

still too small

@Crownvictorialifestyle

Well we could get Tom D to make an intake to put an M90 on LS engines, talked to him last week about tossing a 6-71 on one of my 6.0s.. Now what I want to know is how well a 6-71 will work on a 505ci Pontiac making around 700-730 between 6000 and 6500 NA. Oh yeah Tom D and I are friends up here in Michigan. Gonna put a hurtin on his Sonoma/S10 at the Fun Run dyno day.

I have a 6-71 and can't get past the fact you have to spin the heck out of the M90 OR IT BECOMES A CHOKE POINT
