S/C tuning progress
I installed an RMS kit this spring (bought from Max forum). The instructions from RMS were total crap, but my father-in-law and I muddled through it. As some of you may have seen at the April BMWCC school, I had to remove the drivers headlight (depo) because the projector housing was to deep - that's about where the the MAF sits. Any thoughts on this? I was thinking of moving the MAF further down and fabricating something to fit behind the headlight...

Anyways, the kit I bought did not come with a chip. The S/C is currently installed on a 93 2.5L OBD1 motor. I put the stock chip back in and the car ran ok - but not well. After a couple of calls I started working with MarkD on some custom tuning. We are still working through a couple of things, but overall the car is running great. We went out for a couple of spins last night, with several updates made on-the-fly. No dyno time so I can't give you quantitative numbers - but I've driven plenty of cars and I'd say this is much faster than a NA E36 M3. Not up to e46 M3 power though. Somewhere in between. That will change soon though!

It should fit. Here is my setup with a 3.5" MAF

I see - you have a small piece above the MAF. Mine connects directly. It looks like it sits quite close to the sc pulley. I'll look into this. Thanks

look forward to see the final product.

Extend it down and the filter will sit right behind the brake duct/air filter.

I returned the car yesterday, it's all done. You can see it at the BMWCC driving school next weekend. I won't be there as I'll be out of town.


P.S. I didn't need a MegaPiss or piggyback! ;) *rockout*

Car is running very well now. I got one final update from Mark to make some adjustments to the maps above 6k RPM. We were seeing ~7psi of boost as we approached 7k redline and the car was pulling strong. I'm also very happy with the linear power delivery.

Feel free to drop by and say hello this weekend at Mosport. I'll be there Fri-Sun. One thing with the Vortec is that it is NOT quite, so this is certainly not a sleeper setup. You'll hear me coming!

could you maybe just grind a bit off the back of the headlight housing?
