Since you have a manual, I think your 4th gear is equivalent to my 6th gear in the 8sp auto trans. Can you do a log in 3rd gear? It will probably be more like my 4-5th gear. My WGDC in 6th gear is around 60-65% @ 5k RPM making 22 psi.

This log covers from about 55mph to about 140 mph. I would say it shows about everything it is gonna show. I only say that because regardless of what gear I am in, the ram air intake's advantage is a function of speed. As speed increases, ram air intake will help WGDC. So that is basically all there is to it. I don't think what gear I am in will change that. The slower I go the less impact it makes, the faster I go the more impact there is. I hope this helps.

Here is a 3rd gear log to redline. This log shows about 485 whp. I'm on e30 but running a pump gas map. Boost is turned down in 3rd to keep my HPFP happy.

WOW your WGDC is really low! You don't get too much air/lean codes? I know someone running the AFE intake and he gets lean codes. He put back his stock intake and no more codes.

Does your intake require removal of bumper for install? Count me in for one of your RAM AIR CAI!

Sounds good! No need to remove the front bumper.

Anytime you make any changes to how you feed the motor air, you are going to need to adjust fuel accordingly. You'll need a tune for this or the MST intake but it is well worth it.

David Shoup is familiar with this intake from a tuning perspective.

Any concerns regarding the low RPM cyl 6 timing corrections, and the timing on cyl 4? It looks like the issue goes away at higher RPMs

I was told not to worry about those at lower RPMs and 5-6* is considered
within a "normal" range.

When you get into the higher RPMs that's when you got to watch it.

I have noticed I periodically get some minor adjustments on a random cylinder on lower RPMs, not always 6.

It's something to watch.

Makes sense!

Here is another log where you can see two 4th gear pulls and barely any timing corrections, each pull has blips on different cylinders (none on 6) but they clear up in higher RPMS... I think the DME is just doing what it's supposed to do and I don't really need to worry about anything... ¯\_(ツ)_/¯

THAT IS ONE CLEAN LOG! Go you and go David Shoup!

[BimmerHausPerformance]

here is another log where I went through 4th 5th and 6th to redline... pegged the speedo! I have started to sell these intakes if anyone is interested.

congrats bro... good work, maybe I'll pull thre trigger one day on this from you

Not sure how you extended the MAF wiring, but I MIGHT have found adapters that work.

They sell both the male and female end, you just gotta crimp your own wires or buy the pig tail version, but tbh I don't really trust their wiring and would rather spec my own GXL wires. The housings came in today and I will be test fitting them later.

Thinking about this but the mst one is looking good too

I appreciate that! I just sourced a MAF extension set up that will be custom made with OEM bmw parts so on this particular part I am good!

It all depends on what you are going for. MST probably looks better under the hood, not gonna argue there, but mine is all the way to the inlet and is proven to make more boost. Plus it is louder since the filter is literally outside :-). Sorry for my bias opinion lol

It isn't cheap but again it is from the inlet forward, the inlet alone just the part is 83 bucks. So the whole set up is 650 plus shipping. Other intakes do not go all the way to the turbo so it is not a fair price comparison. Here are some videos with sound and links.

I can hear that howling noise that I was telling you about on my car.. not as loud, but then again, my intake isn't where yours is either.. but I can definitley hear it

Funnily enough, the male part of the adapter is actually an OEM BMW part. Just verified their adapters work

[95blkmax]

NICE! what about the female side (the pseudo-MAF)?
