If you're tired of keeping your power steering reservoir clean all the time a solution is to change the gasket along the cap however that isn't the definitive answer. If you will examine, your PS reservoir has a vent hole which spews out power steering fluid vapor which in turn coats your reservoir with this black greasy grit. The solution, a quick vent tube that directs the vapors elsewhere.

Parts
BMW Vacuum Hose P/N11727545323
1/8" to 1/8" male to male fitting


Directions
- Clean your messy reservoir
- Attach one end of the fitting to the hose
- Attach other end with attached cable to vent hole (You may need to trim the fitting to get it to fit since it is not exactly a 1/8" dia.)
- Route vacuum hose to your place of choice. I chose to vent the vapors to the pavement. The meter long vacuum hose is more than ample enough to reach.

Looks pretty original if you ask me and you will no longer have a dirty reservoir to clean anymore




Wow cool idea!

I'm assuming what you are talking about torque and power as a function of pipe diameter, yes? The old myth that says:

Wider pipe = less back pressure = more power/less torque
Narrower pipe = more back pressure = less power/more bottom end torque

This is an myth that only has a stay in motoring because it makes sense intuitively. The fact is that narrower pipes, when designed properly, increase the exhaust velocity (venturi principle). Greater exhaust velocity leads to lower pressure in the headers, and ultimately scavenges exhaust gasses from the combustion chambers more efficiently. It is not back pressure that increases bottom end torque, it is the scavenging effect.

It follows that a wider diameter pipe does not reduce torque due to less back pressure, but rather because it reduces the exhaust velocity, and thus the scavenging effect within the combustion chamber/exhaust port. The benefit is that, because of the lower exhaust velocity, wider pipes allow the same mass flow rate with less kinetic energy in the expelled fluid, which means more top end power.

Someone correct me if I'm wrong, but please provide supporting info.

Additional 12V Power Sockets and USB Charging

So this really isn't a new idea, but I can't remember where the idea came from, but here is my first DIY. I searched to see if I could find anything similar on here, but couldn't find something exactly like it. So if there is another like this, feel free to let me know, and I'll ask a mod to remove the thread!

Mod Name: Glove box charging!
Mod Cost: Depends on the outlet you choose
Mod Benefit: More outlets and USB charging

Finished Product:




Part List:
Add-a-Circuit (Direct Wire Fuse kit)
Inline Fuse Holder (Radio Shack) holds 5x20mm fuses
6.3A 5x20mm fuse
sheet metal screw
20 Gauge wire
18-22 Gauge butt connectors
3M Double Sided Tape
Outlet (the one I used)

Instructions:


Step 1:
Remove the glove compartment.

Step 2:
Prep the adapter. Cut the wires, find which one is positive (use a multimeter) and wire in the in-line fuse to the positive wire.




Step 3:
We need to find a fuse that only gets switched on with the ignition. I chose Fuse #26 which is the Garage Door Opener. Place the 'add a circuit' in the fuse slot, and then add the original 5A Garage Door Opener fuse along with another 5A fuse to the two open slots on it.




Step 4:
Drill a small hole in the right bracket by the fuse box to make a ground. Make sure your drill bit isn't cheap, because the metal is pretty strong. Attach a ground cable using a eyelet.




Step 5:
Run the wire from the fuse box up, behind the whole fuse module and then do the same with the ground - make it as neat as possible.


Step 6:
Attach the wires from the fuse and ground to the postive/negative leads coming from the outlet module using the butt connectors.




Step 7:
Attach the outlet module to the metal top using the 3M tape, put the glove box back on, and viola! You now have extra outlets in your glove box!

I don't understand. Aren't you fusing the same wire twice?

No, I believe one fuse is for the original fuse (the place that the add-a-circuit took) and then the second one is the one for the wire.

Partially correct. The fuse is also acting as a voltage regulator and preventing an over voltage on the USB circuit board. The source was a direct tap to a switched fuse on the board also so there is no other fuse present.

Just better to be safe than sorry!

completely correct. its all about exhaust velocity, and not backpressure. still surprises me how many ppl profess otherwise.

Free mods / cheap mods under $10 DIY

Can we all agree to stop asking if your car supports the golf tee mod? Just ****ing walk up to your exhaust and look inside it. I think roughly 70% of this thread is people asking the same damn question.

You dig up an old thread and get mad about something that hasn't been asked for months? Lol.

Bumper Mods

Considering I had the ugly non sport front bumper with the large black number plate holder & long fog lights, I cut the bottom of the black plastic number plate thing to look like the number plate delete strip ($25AUD?) & added yellow headlight tint to the fog lights (seen on many e30's and such).
