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.

Pictures of the concept & prototyping phase...








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.


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.




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.

Hello Hyde and everyone. Im jumping out of my skin as I read this because I just got my 1994 318i vert back from my sis in California and I have been drooling over the DASC set up for years but just too much $$$. My cars only downfall is that it's an auto with the GM 4L30 trans which said thank you after I did a fluid and filter change at 90k. I did not believe that lifetime fluid crap. Anyhow, Im SO DOING THIS and most likely with the M65 because why not right and are plentiful. Tuning has always made me wonder since its OBD1 1994 BUT it sounds like u got people for that. To think I was considering an LS swap when all I wanted was some low end torque and the thing not to get smoked by a Prius. Ill gladly guinie pig for you if you need one but all good if not I just cant wait to see the end product and happy this thread is new too...
