===================== Edited on 13/07/2021

Welcome to my thread, this will my ultimate guide to doing a budget DIY supercharger build for all the M4x engines found in the 3 series & Z cars. Starring Red Rudolph the Ti.

About the Setup:
We will be building around 4 different superchargers. Yes, Four.
First the Ogura AMR 500 (~500cc) and SC14 (~1430cc), Next the Eaton M45 (~740cc) and M62 (~1015cc). Those are the rough displacements of the superchargers. All of them can be had for next to nothing, around $150 for the AMR 500 band new, and Around $400 for an SC14. The Eatons go cheaper and abundant, usually you can grab the Eatons for as low as $50 - $100 from yards or parts places all over USA, Canada, UK, NZ, Europe.


Now if you remember from the list,
DASC Used the M62 and GDK IIRC uses the M45.

Enter the HMW M.O.A.B. - The Kit itself will maintain the AC, The Alternator, the Power steering. The SC14 & AMR500 will retain the stock manifold, while the Eaton M45 & M62 will require you take off the top part of the M44 Manifold as well as needing to either raise the hood hinges slightly in the rear or use a low profile hood scoop to clear the hood a little. They are all roots based blowers so all the power is available low end.

DASC Used the M62 and GDK IIRC uses the M45.

The Eatons and SC14 also use their separate belt drive while the AMR500 incorporates the oem belt drive. For M42 guys, you must go with the M44 Manifold. The Eaton brackets should also be able to support an smaller M90 (Jaguar or Thunderbird) but support is not official, however in the future if the project takes off well, then we will incorporate the M90 as well as the almighty Eaton M122H GT500 blower on these cars.


Boost will start from around 5 - 8PSI if using either the AMR500 or M45 and upto to 10 - 20PSI with the M62 or SC14. Making these setups good for 200 - 300HP's + if your motor can handle it. :wink:


Tuning I am not a tuner, but from my research on these motors, So far majority have been doing it using an old school method of the rising rate fuel pressure regulator, thats for most people running upto 6-8PSI. However a proper tune has always given so much more. The M42 will likely have to be done by Ostrich II type piggyback, While the M44 will need a bench flash, its easy enough to build a bench flasher but the tune from a tuner and data logging is going to be the key. I have spoken with Barry from Midnight Tuning a while ago, and he will be whom I recommend for the tune.


A little bit about this project, after returning from Germany this year, I bought this Red 318 Ti from a local club member in NZ as a daily. I got it at an offer I couldn't resist. On my way back which was a 3hr drive, I was grinning the entire way, just the way this car felt, it has a character of its own, I couldn't help but fall in love with the car.

I have been supercharging BMW's for a good part of a decade now. And have my setups have gone around the world from races to shows. For those of you who have seen our work they know it to been mostly for the bigger engines as the M5x (6 cylinder cars). So I thought its time for a 4 cylinder project. I have first hand overseen this V4 project and worked on it with nearly a hundred man hours on the final prototypes. After I am done here, the 3D & CAD modeling team will take over, once they are done it will enter semi production stage in the factory. I estimate another 3 months before these are publicly released.

A teaser of the crazy things we do. Here is the HMW M122H KC. :wink:

A quick video to go a bit more into explaining the prototyping and all. (the youtube button is not working it seems I will just post the video url)

I know DASC & GDK have both offered SC kits at a stage for these cars, those used a custom manifold. The HMW kit will be the largest and most comprehensive yet. Now you are no longer limited by one type or supercharger, you have the option of using a much larger SC than anybody else, you can even inter cool it! and best part, the kit will be priced around a grand or so, that's including the custom sc manifolds, belt, idler pulley's all powder coated & shipped anywhere in the world when it hits the market.

Now we finally have the ability to bolt something on and make far more power than the typical 6 cylinder swap while being affordable for you all.

I want this to be a community project, when the time comes I will pick few from here interested to try the setups. Till then this is the thread I will be posting updates and progress in. So drop a line, some encouraging words, perhaps some feedback, give us a cheer, tell us what you think. :smile:


Best Regards,

Following! Very excited. Cash in hand, too.

Couple questions: how are these blowers compared to the one used in the DASC (flow).

Have you reached out to Nick G./TT about tuning? He also several tuning options for the DASC; could this work also?

Following this too.

Oh DASC used the Eaton M62 Supercharger, we support the M62. GDK UK was using the M45. We support that too.

In addition the SC14 is nearly 500cc larger than the M62 Eaton, more flow. We use those on the bigger 6 cylinder cars with nice results.

Haven't reached out to them, but maybe in the future. :smile:


Definitely! Thank you! :biggrin: :cool:

This is looking great!


I only wish this was available ~2.5 years ago when I swapped in the m52! Maybe I should swap back. :tongue:

Which of those superchargers will support the 300hp? Would that setup need intercooling, and where do the stock injectors max out?

Well, :biggrin: maybe its time for more power, you could try the SC14 to make a small bump, or even an Eaton M62. or the M122H to blow the motor up. :tongue: We have a lot of setups for the M50/M52/M54 actually. :wink: Will throw in a discount down the line if you ever want that route.

300HP at the crank or rear wheels? if crank then thats no problem with the SC14. I would definitely say some larger injectors like #30Ibs or even #42Ibs will be something for anyone aiming to hit 300. Thats what we do for the 6 cylinders. The kits will all support air to air intercooling as well. Most we have seen from it was 360rwhp on a S52B32 motor in the american endurance races, our team won 3rd place there.

On a small 1.9L M44 though if you can build it then you can really seek serious power. I intend to try doing a M122H (GT500) setup on it as well with help of my Chief Engineer, Keith in NJ. If we can manage a M122H on the M44 then it will push 30 PSI + and put you in 400+ HP. But that setup wont happen till these are done. Here is what the 6 Cylinder M122H looks like :wink:

https://hydemotorworks.com/wp-conten...-Full-Kit.jpeg

Some progress today, some more trials with the concept then its almost done.
Just wait, we will do something great for the Ti community.

Just educated myself a bit on the SC14. Pretty excited to see where this goes. The clutch that lets you switch it on and off is especially appealing to me. 300 crank would be terrific! Hopefully that's attainable on an M44 with just head studs? Edit & re edit: reread original post

Unfortunately for us guys with an eye on FI the M44 has been engineered for N/A performance and can't really handle much boost stock. From the research I've done so far the consensus seems to be 6-7 psi max, much more can lead to various failures pretty rapidly. The M42 is slightly better off as it has a forged crank but again to run more boost you'll still need to lower compression initially and then build the engine from there.

If you've never come across Metric Mechanic before, I'd highly recommend checking these guys out. They really know how to build an M42/44 and are pretty open with what they do

Awesome thread!

If you ever need a test monkey M42 in NJ, im your guy ;) hoping to save a little cash and play with this kit. As always it looks great on that little motor haha. Im really enjoying watching this progress and I appreciate your support for the 4 cylinder crowd.

You have my attention. I will be sending you a PM with some questions.

:biggrin:

������all money in

I'm super super stoked about this I can't wait to get in I would love to be picked from the bunch I definitely want to be the guinea pig ear

Just looking at the list of SC's, will you be doing one for the M90?

so far I've been doing a little research in the best place I seen to get the sc14 supercharger is off of eBay do you have a better source or do you know of a better Source can point me in the right direction I'm interested in going big or going home

Eaton M45/M62 final drafts done
 

Hello Everyone,

After many days of labor, as of tonight the Eaton M45/M62 based designs final technical drawing whiteprint drafts are complete. Next week it is going to our 3D modeling & CAD team, then the final prototyping. We should be able to release the finals by late August. I will get back to you all at some stage tomorrow. :smile:

Far the days come..

Do you need a downpayment on one to help the process? :)

Boy oh boy
Can't wait to see this happen
And I love the fact that you're trying to keep it at a great price point that way you can get a lot of people involved in purchasing this kit

Will there be a significant difference between the cost of a kit that uses the bottom half of the manifold for the Eatons vs one that retains the stock manifold fully?

������this is great
I was wondering the Same thing too

Hey again guys, thanks for all your support, So let me get back to the questions. :smile:

Hey there, an M42 and near NJ? I think I will take you up on the offer, I was looking for a few folks to try out different superchargers. Tell you what, I would like you to try the Eaton kit and use the M62 (same SC used on the DASC).

See if you can find the M62 from a Mercedes Kompressor from local yards or part guys, they are plenty usually.

Meanwhile, if you cant, we will supply you with a unit to test. Now you are about an hour away from the HMW K.C. workshop in Vineland, NJ. So we will just double check if we have one laying around, if so you can go pick it up from the chief engineer Keith there. :wink: Just be sure to return it afterwards.

If you like then drop me a line and we will work it out.

Thank you my man, I got your PM, I have some suggestions to make most out of what you got instead of spending more money(anywhere including us). I will write to you later today.


Hey Ollie! Well the M45/M62 brackets are actually an adapter away from the M90 from the Jag or even something larger. I haven't got plans to incorporate it till maybe later in the year depending on how these setups go. But really its about mounting the M90 adapter on top of the current brackets to make it work. The M90 used should be the ones from the Jaguar, Aston Martin or the Ford Thunderbird as they are short bodied. Also you will certainly need a hood scoop for an M62 or m90 as it will sit quite high. Maybe one of those muscle car hood scopes will go well with these cars. But if you are making more power than a Z4 3L. Why not.

But yes if you like, we could work something out. :wink: But watch out, The other downside is the M90 is slightly larger (40-50cc or so) than the SC14 and about 10% more efficient. You can easily blow up our little M44/M42 with them if you are not careful.

What kind of a car did you have there? I could use a few testers. I can take you in. We can work it out late July.

There are a few sources, we usually supply ours from the UK but airmail takes a hit. On Ebay they come up time to time, this is a store who list them often at good rates - http://www.ebaystores.com/foreignengines and we have bought from them before.

There is also AliExpress - where I suggest anyone looking for the AMR500 grab theirs as they are going at a good rate ($180 shipped)
https://www.aliexpress.com/item/32289771813.html

There is also the TVS Eaton
https://www.aliexpress.com/item/32662649749.html

the TVS R410 is around the same size as an AMR500 (~500CC so only good for maybe ~5PSI at most) But more efficient and used in the new Volvo twin charged engine. This should work with our Eaton M62/M90 brackets if adapted, but not yet officially supported just like the M90.


That said, if buying the SC14 from Aliexpress, ask for the actual blower's picture so you know the condition. Of if you are really interested let me know and we will work something out.

Thank you! We want it to be something that is realistic, affordable and anyone can do, making great savings while we can still make a profit to keep offering the public what they want.

Hey there! thats quite alright as we finance all projects ourselves. But much appreciated. That said however if you would like to test things out, I can offer a 50% off when I have the final prototypes and supply the kit, you grab the blower.



Hey there! So there wont be any difference, all will be priced the same just around a $1K-$1.2K shipped all powder coated with accessories. I intend to make the AMR500 kit cost a lot less as it has less parts we need to manufacture.

But overall there will be 3 main kits, one for the AMR500, second the SC14, both of them retain the stock manifold. If anyone who bought the AMR500 eventually want to upgrade to the SC14, we will cut down the price half and upgrade them) so that way they dont pay more than its worth.

Then the third setup will be for the Eaton M45 & M62, for the eatons we will be using a mini plenum adapter (hence only top half needs to be removed for eatons) Anyone who wishes to try the M45/M62 will get a kit that fits either one of these.


------------------------------



Anyone here have any GM M90's locally? I think they are abundant and if I could make it fit, it could make things easier for a lot of people in the future who want even bigger power although I dont say take the boost any more than 8PSI on a stock motor, specially not without a proper tune.

Count me in. Need me to PM or email you?

Done, Drop me a PM when you have the time, I cant take more than 3 testers (as then I will have to make more final prototypes and lose money).

Once I have the brackets and do some testing of my own and approve, then we will talk about payment and shipping (late July). But I will try to keep it at $500 -$600 shipped and all just to cover production and shipping. Grab yourself a blower locally (the yards sell the eatons very cheap- just need the right one) and then do a log. That's all I ask.:smile:

So, 1 In. I need 2 more testers. Aiming for Late July. Want M44 and M42. :redface:

Acquiring a blower before then is probably not likely for me :( ill keep an eye out for a good deal however. Sounds like a good time playing with one of these kits

We can supply an M62 at no extra charge - should have a spare, use it till you find your own? But I will need you to try it on the M42 of course. If that works and you can do some quick bolt on tests and later a build. We can work it out. :wink:

Im in, whatever I can do to help. Im sure we can work something out.

You've got me tossing up whether to take you up on the offer of testing for you vs my original TC plan :confused:

My biggest issue is SC sizing. Ideally I want to run around 350rwhp but with the possibility of turning the wick up to some where around 450rwhp even for just a short time. I will be running an IC, and any other mods needed to support the power.

I'm not speaking from personal experience, but at those power levels you might want to consider if it would be more cost effective to do an M5x swap and turbo it on stock internals, as I'm pretty sure you're going to have to do an all-out engine build to support that power on an M42.

Now that you mention it, it just so happens I've got a spare M44 and an M47 crank sat in my shed [emoji6]

Right now on YouTube there is a E30 on Boost with stock internals reaching 316 horsepower 280 ft lb of torque on stock internals it's called the everything guy E30

https://youtu.be/kTIQ3pTk68U

Check it yall
Let's keep this awesome thread very much alive

Alright, lets be in touch and I will have it sent your way towards the end of July.

Well, I kinda was going to say what bimmernut was saying, I mean to get the M44/M42 anywhere near 400HP would be a milestone built. Some will say you will need 30PSI, I would say 20-25PSI from a M122H would do it, since we are working with a motor that makes maybe sub 150HPat the crank. Now 450rwhp is more so asking 500 at the crank. Depends how deep you want to go into building that motor, know you can stroke it to 2.1L or so but even then, I dont know, for that kind of power you may be better off going with a 6 cylinder swap. The only setup that could do that would be capable of those levels is the M122H. We could work something out if you really wanted. I can adapt the M122H KC Discharge pan, to fit the current gen Eaton MOAB Brackets, but it will be sticking out of the hood a good few inches for sure. Also comes down to what you spend, I mean if you can do the work yourself, maybe a few grand and a lot of work will get you going with the TC setup. Totally your call.


--------------------------------------------


For the testing:

So far I have got

thenjnick - M42 with Eaton M62 Build
niceguyeddie - M44 SC14

I myself got an M44 here I will be testing on, I will do the M45 & AMR500. Unless anyone else wants to go into testing, Lets call it. :cool:

I ran 10psi and 125hp shot of nitrous on my stock 168k engine for 2 years, 160lbs of nitrous through it in that time. It's currently on a stand as a emergency spare if I blow one of my built motors

Very interesting, so at 10PSI, what did your tune look like? certainly larger injectors were dialed in? What size? Was it a M44 or M42? Some more info helps us all in the long run with these motors. :redface:

Yes larger 42lb injectors on that setup and I was running a modified tune for the DASC. It's an m44 in a 97ti tuned the ecu for 10 psi and soft on the ignition table to account for the nitrous, then turned the nitrous with the jetting. It wasn't the best way to do it but was working with what I had at the time. I don't know if anyone has actually found the limits of the m44 or maybe didn't want to try. Well, I'm slowly working on it with my new build, it's the same supercharger setup with a turbo to compound boost, and eventually bring back the nitrous. There's a thread on here about the build. I've briefly did some street tuning at 30psi but had 2 1600cc injectors stick open and flooded it out. So for now I'm back on the 1200cc and 24psi

Are you tuning these yourself? Stock ECU bench flashed? The biggest limiting factor seems to be the tune on most of the setups. That and the fact the 4 Cylinder motors dont get enough love and attention they deserve as you too notice. I like them very much. they are nice little guys.

Maybe if we ever do a M122H setup on a 4 Cylinder, you could try it out since you are into High HP. that thing by itself will put out more than what the current setup combined does. ;)

Yes, I've been self teaching for a while only recently been taking classes for tuning. Originally I was using a stock ecu and flashing it, then I found a piggyback unit that I could use to add some features, but ultimately I went with a haltech elite 1500. When I start playing around with the e85 or e90 fuels I can really start to turn it up. I rolling anti lag launched it on the highway at 60mph in 3rd last week and it spun the 305 tires. Working on a functional rear diffuser for it now cause it was sketchy.

So is your a M42 or M44? I think the piggy back will only work with the M42, not M44. What were you using to data logg? post some more info, I am sure some will find it useful including myself. I wonder if you could be of help some of us guys here to get some base maps started. Most will use the stock ecu as you know.

Both of my ti's are m44. I used the det 3 from ECU masters. They didn't have a diagram for the m44 but I had it wired in to crank, cam, maf, vehicle speed, and the output from a AEM wideband afr gauge. I could only modify the timing about 5 to 7 degrees without setting a dtc but I could completely modify the maf signal witch I stepped up to a 4.8is x5 maf housing with the OEM sensor in it I think it is about a 3.5 to 4in housing. It also allowed me to add a launch control/2 step on it, but it would throw cam plausibly codes if used. But since I already had s supercharger tune in the ecu it worked for me to make more fine adjustments on the fly, and it also had a data log feature and street dyno feature so you could get an idea of improvements. I was fairly impressed for what it could do, but I am really liking the haltech elite with it being obd2 complaint. I can set all the same failsafes of the original system and more it throws p codes and can be read by a normal scanner. I can also plug a bluetooth adapter into the obd2 port and use my phone on a mount for additional gauges while I'm street tuning.
