well, it's finally done!
M90 supercharger fitted to our little 4 pots.
Goals:
- 7 psi for about 190hp
- keeping it reliable
- buy only what I can't fab.
- keeping the engine clean looking
- keeping it simple
Since I wanted to keep it as simple as possible, I opted for the DASC sytle design
here's the build in pics...

I didn't want to pay 150$ for a K&N filter with the bracket adapter and wait for the part to arrive in I don't know how long, so I made my own 3" filter bracket for the AFM...
3" aluminum pipe and 1/8" AL plate

Find hole locations and then cut

Fibreglass the peices together through the interior and then once it's dry apply 2 layers on the outside

Then trim and paint! no picture of part alone...
To keep it simple, I used the power steering pump as the tensioner, but before I dissabled the pump as not to move extra fluid around.

Onto the building part!
a common sight to most of you...

I didn't like the idea of a 25lb wight just hanging from the head, so I added an extra steel bracket that bolts right where the alternator bolts on.

Manifold on!

Blower on!
(http://i729.photobucket.com/albums/ww298/B318M42W/29-09-10_2305.jpg)
In order to keep it clean looking, and also for space reasons, I tucked all the piping under the manifold and elbow, in the large hole right beside the starter
(http://i729.photobucket.com/albums/ww298/B318M42W/31-10-10_1550.jpg)
Rest of the intake on!

For the details
- #40 injectors
- stock internals
- LC-1 WB 02
- bosch bypass valve
- modified rad hose
- 1:1 pulley ratio giving 6 PSI
- estimated 185hp
- no intercooler
- cooler plugs
- 255 lph TRE fuel pump
- Tuned chip by midnight performance (great to work with!:D )
- relocated P/S reservoir
- stock throttle cable and TB
- 3.91 LSD Medium case diff
- 17" rims
was it worth it? YES! the torque is amasing! a little too much for the stock clutch to handle so it's on the wanted for x-mass list. It's really great to drive around and play with! best of all, it drives really great around town when getting lazy shifting gears. She has a really nice purr at idle however can't hear the charger under load (pulley ratio and loud exaust).

very cool!!
and not to be a dick but those wheels....
not feelin them! lol
-
That is really, really cool. ;)
-
Nice work, man!
-
what car did this supercharger come off of? did you convert it to vbelt?
-
thanks for the comments! The charger is off an early 90's thunderbird acording to eaton, but it seems to be almost brand new! It's still in V-belt but i'm considering going to serpentine in the spring

looking good,how does it run.
-
you should fab a few more intakes.. im sure someone would be interested in them :)
-
It runs great! it runs just like if it had no charger and when you step on the gas, it just goes! lots of instant torque, when you want it.
As for the manifolds, I guess i could fab some base ones, but not 100% done since charger bolt pattern and position differs from model to model.
-
your welcome /\ hehe :P
-
in case anyone was wondering. it looks like this is an m90 off of a jaguar because of the short snout.

True, but i sent an email to eaton with serial # and this is what they answered
Dear _____,
This unit is from an older Ford M90 from the 3.8L Super Coupe.

Pretty sure fords are easier to find than Jags :p
-
So you're on the stock motronic? All you have is a wideband 02 sensor and a chip? Seems like a better option than a turbo:p, you can find thunderbirds in the junkyard all day.
-
Yeah stock ECU with a tuned chip, WB O2 and #40 injectors.
-
very nice, it would be cool if you could make some more intakes.
videos?

Sry but no videos will be availible before a few months. Car is stored for winter :(
However, I'm working on putting a kit together, just like mine, but an upgraded version. It would have all the peices needed to build including a tuned chip, but NO s/c. The only reasons I would not include it is : it weighs 25 lbs, and i see no point of shipping it twice. and 2, a practicly new factory? rebuilt one costs 850$ or you can find a used one for a lot less money. option up to the buyer. (but has to be just like the one i have)
The kit is still in the project stage. If I see there is interest, I'll go forward with it. For more information, pm!

estimated price? I would be so down for one.
-
estimated price at this stage is 2300 can$ + YOUR supercharger , no tax, not fixed yet. As a price indicator, the DASC went for 3400+tx, usd. My kit will include important tuning/monitoring components NOT included in the DASC kit.
Thank you for your interest!
-
I don't speak about fluid dynamics in that manifold... :eek:
it's too slim to have that square form.before you start selling these you shoulf check INDIVIDUAL AFR IN CYLINDERSVIA 4 WIDEBAND SENSORS IN THE HEADER.then you'll see.
dasc manifold is not this slim and it's not square inside. Ever heard about vortex?
example, your is a lot more poor than this...:
(http://i34.photobucket.com/albums/d101/keatonstanley/CDF%20intake/T2_1.jpg)
I bet you have to work a lot to obtain a ready to sell product and optimize some things....
nothing against you, want to save you the hassle of customers screaming for blowing engines.
If you check there is space for intercooled version, don't ask, I know ;)
-
I agree with nuvolarossa, make some research(google) before doing something.
-
working on it, thanks for the heads up! might design a new manifold that will allow the use of an air/air intercooler.

As long as you are working on a more refined kit, I would suggest working on a part-throttle bypass sytem as well.
I am interested, even with the current design. Keep me/us updated.

I would like to read more on this subject, can you guide me?
-
How are you driving the supercharger? You still have A/C and power steering and all that?
-
She's driving pretty good! I need to keep an eye on the belt tension and looking to upgrade it to a double belt set-up. I'm using the P/S pump as my tensioner... pump is disabled (had issues with the system before the build) and A/C is not driven. With the double belt design, no A/C will be possible.
-
But with the single belt setup A/C is possible?
Could you try and get a clear shot of the pulley/belt setup? I'm interested in doing an SC setup if I could keep the A/C, even if it means sacrificing my PS.
-
I can't get anything from the car at the moment, as it's stored for winter. but yes the single belt drive and A/C is possible. the crank pulley has 3 belts on it: 1 for alternator/water pump, 2 only a/c, 3 only p/s (and s/c). I think that it's better to sacrifice p/s (even iy you can technically keep it) but it will add some resistance and belt may slip early on the crank pully. Anyway the E30 318's drive fine without p/s.
Depending on your power goals and blower selection, belt slippage/tension will be an issue for single v-belt. depending on your budget, you could always look into a serpentine belt conversion to avoid those problems.
-
I'm so glad to see my old blower put to good use! Good job!
-
UPDATE: after a few thousand miles, some issues came up... the s/c belt streched and after re-tightening, boost level was up to 10 psi. 3 psi OVER so AFR a little tooo lean (but pulled reallly hard!) turned out that the belt traveled down the s/c pulley groove. just 1/8th on an inch down forces a lot more air in (oversized s/c). remedy: get a 1/2in industrial belt OR just stick with an automotive pulley...
next issue: alternator belt needed replacement, but couldn't loosen all the way since i have a bracket installed there. needed to pry it into the groove.
all in all, still very worth it! just a little heads up for anyone trying to do the same as i did.
oh and next move: intercooler with a tunable setup! (variable boost from strap tension!)
-
op have you race any other car to see where you stand at?
-
once, but didn't master the clutch for the extra hp (bad shifts = slipping clutch) but even with massive clutch slippage, a mid 90's 626 wasn't a problem (only had enough room to get up to about 40 for next red light). Didn'T build it to race ricers, did it for fun and easier overtaking...

why you have ricer wheels?
-
needed summer tires and had the deal of the year and just couldn't pass up.
-
If you were starting over would you stick with an M90 or try to find something smaller like an M62/M45?
-
I'd try to find a short snout M62. why? blower speed is slow and can't hear the much apreciated "whine"(on M90), and I'd have more room for stuff along with hood clearance. On the other hand, I think that the larger M90 produces a little less heat than the M62 (doesn't work as hard)
-
My main thought was concerning packaging, although neither of those I mentioned are that much smaller. The secondary thought was how an intercooler/piping would be routed. Speaking of which have you had any time to consider intercooler plumbing? Thanks for answering my rather open ended question.
-
I have given it a thought before building and found that it was much easier to run without given it was under 8-10psi. Then i became addicted to the power and considered IC piping using my existing setup. but, if i had to start from the ground up, i'd leave more space between sc and lower manifold and also move it down a little. this would permit me to still bolt it to the sc manifold but have an air path that leaves a little under the lower manifold runners towards the front and through the belts or to the left under the sc. and then have the IC air flow run on top of the fuel rail and enter the fabricated manifold in the middle. Not sure if you understand what im trying to explain...

Hello all! I am new to the forum, from Calgary, Alberta, Canada. After recently purchasing a 1995 BMW 318is from auction, I have decided to Fab an intake manifold for the M60 supercharger I have also purchased, came from (2000 Pontiac GTP) I have already done some minor upgrading to the car, cone style airfilter/removed cat & resinator, 2.5" exhaust... I still cannot find out if it is an M42 or M44. Is there anywhere I could find the layout of holes and ports in the head to start planning and designing the fabrication prints, as this is my daily driver at the moment, and would rather not remove the intake yet... At least I could start basic fabrication of the flanges, as I am a ticketed welder/pipefitter, and can stay late at work to build it, and have access to an unlimites supply of scrap!
And a couple questions... I see you are using #40 injectors, and WB 02, sensor, where could I find these? Do you require the bosch bypass because your M90 does not have the bypass port? Or what exactly does the this bosch bypass do? I will be contacting Midnight Tuning for chip info!
After a lot of research, these upgrades seem like the most bang for your buck!
-
a good way to get a decent general bolt pattern would be to order the paper gasket. I found the injectors from another member and the WB02 with gauge off ebay. you REALLY want a bypass valve if there isn't one incorperated into the blower you have. it allows for normal manifold pressures at idle and cruise. Dont forget the blower always pushes air into the engine even when it doesn't need it, that valve prevents that ( example: afr @ idle without valve 17-18:1 and in normal you should have 14.7:1 )
hope that helps!
