Maybe you can use V2's hacked up intake manifold for a start on the plumbing...just a thought.
|
that little guy is probably short enough to mount on top of the AC bracket.
with longer blowers (Jag M90 included) part of the problem is interference with the driver-side engine mount "arm" to the point I was considering making a whole new one. there is tons of space in the 944 bay once the stock airbox and intake manifold come off but that arm cuts potential blower space down big time. re: my manifold, i do intend to have a different intake manifold made so the ready-to-run box type i have will be for sale. if anyone were interested in taking it off my hands that would speed up that process, lol. nothing wrong with it, this box manifold was the one that blown944 used on his supercharged 944 drag car years ago, i just don't like the aesthetics of it :eek: |
Perhaps but the MB SC uses a hexagonal hole for the output rather than the square one the American companies use. First thing is just to get the thing in my hands, see how the bearings are and grit blast it and make it purdy. Then this winter I will get under the hood and take off stuff to see how it might fit. I'd prefer to keep the existing stock manifold if possible.

you really want to put the TB ahead of the supercharger when using an eaton/roots, though i guess if you keep the clutched pulley on the MB blower you can put it after the SC...but that limits your boost options a lot for the future.
|
Yes I have seen it argued both ways on the endless "hot rodding" forums. I was hoping that I can use a bypass valve arrangement to get this to work with the TB after the SC. Could that work?
I do not plan to use the clutch. I will remove it and replace with a quick-change like pulley thingy. Edit: After more research I will try and mount the TB before the SC. |
In the bmw tuning World, rotrex is wery popular, they run With the sc And a bow.

Spencer, What were you planning to do about fuel? What injectors? Is there a higher (3bar) fuel pressure regulator for early 944's?
|
i have VEMS ECU so i can use whatever injector i want.
i have a set of 55lb/hr and a set of 72lb/hr on the shelf. i'm sure there's a 3 or 3.5 bar FPR that will fit the NA rail, haven't looked too much at it since these injectors are more than big enough to work at stock 2.5 bar. |
I’ve been searching for the S2 with a 968 supercharged engine built by 9meister which put out 350hp and I found the old ad but not much more. Anyone have anymore info on that car?
9meister supercharged 944 |
I've been running a Rotrex supercharger on my S2 for 5 years now. I have been running it hard on the track for all of this time. You can find details in my thread. It's not hard, but takes a lot of time and thought to get it right.
I wouldn't run an Eaton. |
I had superscharged (procharger C2) S2 and it was fun car to drive. Around 350hp with E85 it was quick enough. After that i couldn't even consider NA versions of 944. Now that engine is gone and there will be 1.8T in the engine bay before next season. I think any right sized supercharger will make 944's a lot more fun to drive. In case of self contained supercharger the installation is pretty straight forward.

no question the rotrex/etc are superior for higher-end HP. great choice for bigger engines like S2 (or all the common V6/v8 cars) that are fine down low but could use more top-end.
2.5 944 needs all the low-end help it can get, but no centri will give you that like the eaton will. I don`t agree. A racecar needs mid and top end power. But for a daily cruiser, it might be the litle extra. |
