I'm still interested as well. The only thing I am still uncertain about is what type of air metering to use. Still have some concerns about using the AFM upstream of the SC due to turbulence effects. I may still be coerced into going with the Vitesse MAF kit if I have to (price issue only).

Excellent -- drop me an email or PM and we'll see if we can get something lined up.

You've ruled out a MAP approach?
Oz distributer for Rotrex is fairly local too:

Unfortunately it doesn't look good for an S2 kit from Carl - as I don't want to be cutting and modifying to install (and I want to retain the headlight mechanism) as per the current design. AC will have to go though.

Planning to go with the Raptor still at this stage (support the local business).
How does the Rotrex rate with adiabatic efficiency?
Yeah - it would be good to catch up with you and Mark.

OK here's a brain dump:
I plan to use a 944 turbo airbox, AFM and intercooler. Bolt-in. Turbo AFM has enough capacity for the hp I'm after. Pipework very similarm to 944 Turbo. Haven't decided where to mount the throttle i.e. stock location or between the AFM and supercharger. Between the AFM and supercharger is "better" and can be done simply.
I don't like cone filters or K&N's so the turbo airbox solves this problem and looks factory (stealth?? heh heh...)
I would like to use the Raptor (good price and great support) but don't see how it would fit. The Rotrex is notably smaller.
Plan is to use the Bosch 759 injectors and go with the Turbo FPR with either rising rate FPR on return line or stick with the 3.8 bar S2 FPR, tune to suit in either case. There's a Motronic guru up north who does all the BMW's for the E30 race series.
Cheers,
Mike

Mike - didn't realise the Raptor would not fit with AC removed. What is limiting the fit - is it the radiator hose or the air intake pipework?

Don't quote me on that - if anyone can get it to fit, Carl can. I want to put the supercharger in place of the A/C head unit, and it doesn't look likely that the Raptor will fit between the block and the side rail. I would need a Raptor unit to confirm.
Plenty of room down there for the Rotrex.

Published figures should be taken with a pinch of salt.
I can believe that the Raptor is more efficient than the Rotrex. The proof of the pudding is in the eating, however.

You guys been in contact with Peter on the UK forums who has s/c'd his S2?

Reviving an old thread with some further considerations.
Looks like the S2 AFM has sufficient capacity to meter a supercharged engine with around 7psi boost. So may reconsider keeping the AFM.
Has anyone mounted the SC in place of the AC before? I can see how mounting it up top (and moving the alternator down) can work, as it uses the same mount points as the alternator bracket and you can then mount the alternator of the SC bracket.
I can see advantages in locating the SC down low, as it should make the inlet piping easier?
Any ideas how you would mount an SC where the AC is mounted. My concern is it would not be rigid enough.

Henk,
Does the rotrex bracket also support the alternator?
I'm also curious as to why you cut the hole to get the intake back up to behind the left headlight. Why not just put the cone filter behind the bumper cover? This is one of the benefits I see in mounting the SC down low, as you could then run a bend up from the SC and locate the cone filter behind the left headlight area. I'm not sure it is possible to get the air filter up high with the SC mounted up high as per your installation without cutting of sheet metal.
