HI everyone these are my 2projects completely different set ups and drives but roughly the same power the d reg one is undergoing a transformation as we speak

Nice and love those Euro bumpers.

Wow, super clean! I love em..!

Beautiful cars. Specs on the engine?

[bungles27]

The d reg car is running a ms1 with 30lb injectors with a decompression plate set @8.1 with a six branch manifold and full system eaton m90 running 6psi and a 75bhp of nos but is undergoing a charge cooler set up with water injection

[bungles27]

And the b reg is a almost standard high compression engine running a rotrex charger with a custom intercooler and pipe work and a g tech pro x ecu

[bungles27]

I've just built a stage 3 head to fit on the dreg car and hoping to turn boost up to be near 350bhp

[bungles27]

This was my first dyno with mega squirt hoping to make a lot more power this time as car had massive air leaks and my bypass valve wasn't working properly

What color is that?

[MasterC17]

Car looks great!

Nice, hp must go above 300!

Alright fellas , I'm new on here so hello to you all, apologies in advance if I make a tit of myself as I'm new to forums as well as BMW's. I have just picked up on the supercharger thread and am pretty interested as I have picked up an 85 e28 m535i , all in pretty good order (79k on the clock ) .
I've been working through it putting right all the dodgy bits and it all pretty much works now and is running well.
So , inevitably I'm now looking into squeezing a bit more juice out of the m30 if I can .

Bungles27 , I've been looking at your SCer setups and really like the look of your Breg setup for its relative simplicity.( I say simplicity as if I've done heaps of supercharging - which I haven't so feel free to put me right whenever )
Turboing a RHD seems like a ball ache what with the steering box/manifold issues and your Rotrex unit seems to all fit in neatly with what I imagine to be less hassle.
A few queries if I may,
-Have you gotten rid of the AFM altogether or is it hidden down low somewhere?
If you don't have it at all , how do you manage the fuel - i.e what sends the signal to the ECU .(and how does this plug in ?)

-Do you have a bypass setup (as on the Dreg ) for low rev's, or do you somehow manage to get around this another way?( cant see any bypass tubing in the pics)

-Finally (sorry for the essay ) now you,ve been running this setup for a while have you found any major issues like idling problems or anything related to normal road use that is a pain in the arse (Mine will be for road use only )- seen lots of info/builds for turbo's but just wondering why there aren't so many SC's , as yours looks great and it seems like a less hassle way of gaining a decent chunk of power.

I'm pretty keen on your SC setup but want to check that it is in the realms of reality for me to do myself as I have a car which is now running really well (albeit standard)
and from the little experience I have , I am aware that it can be a fairly short step to ending up with useless bag of bits if I go in with a head full of HP figures and no real clue of how to achieve them .

Again apologies if any of my questions are somewhat dim-witted but i'm still at the paint by numbers stage .
Any info much appreciated.
cheers
