    Thread: Boostvalve's Latest Dual Stage MBC Installed!!

      Many of you have heard of Boostvalve, some of you have actually used Ric's products, and others may want some more info. Well I just got my hands on his latest dual stage boost controller. Yes, for awhile I believe he had available a setup to use two Boostvalves with an electronic solenoid, but he just released a distribution block for them to clean up the install. I also decided to take it a step or two above just the simple low-high boost with the flip of a switch.
      What I chose to do is rig up a 3-way switch that could flip from low boost, to high boost, to low boost in 1st gear and high boost in all others.
      Here is the heart of it all...what a beaut!


      Boost from the turbo goes in thru the right side of that block. Not shown is the nylon barb that I didn't have screwed in when I took the picture. The air then goes thru either the low boost or high boost Boostvalves, controlled via the solenoid, and then out the bottom to the wastegate actuator. Pretty simple.
      This isn't gonna be a step-by-step DIY as I don't believe that this is a mod someone just getting into this should do. I highly suggest that you're someone who's actually done some mods to your car by yourself, and are familiar with wiring and taking off interior panels. You also need to have some technical know-how, unless you just want to G-rig it all up. But since this is my girls car , the install was done cleanly and "professionally."
      First I just gathered up some tools. Here's a lil pile of all my shtuff:

      First thing's first, take off the steering column panels and also the center console. There are threads on this in the Mk4 DIY section so go there if you need to. You'll need to pop up the shifter cover also.
      Here is where I decided to mount the MBC.

      Pick whereever works best for you. Used the supplied screws and also some 3M molding tape. Run your vac lines and connect them properly to the solenoid and Boostvalves.
      Start running your wires according to this diagram:

      I brought them thru the shifter console as shown here. Red is power and just goes straight to where I'll have my switch mounted. The yellow and black wires will be used with the 1st gear switch:

      Here's the 3-way rocker switch I used. I measured and used a dremel to cut out the square. The switch just snaps right into place:

      Here's the underside with the wires connected:

      Final mounting orientation and what the hoses and wiring looks like. The loom is used to keep it looking clean but there's no need to really use it.

      I hid the power and ground wires inside the loom I'm already using on the stereo power wire. I positioned the fuse right next to the stereo fuse.

      Now the trickier part. The 1st gear switch. You need to mount in in such a way that only 1st gear will click the switch, but 3rd won't. Reverse is fine since who needs 20+ psi in R? I had some spare metal and just cut and drilled and stuck together with 3M molding and bolted to the shifter ring. Made sure the switch was oriented correctly and screwed it into the metal. Then I made the connections:

      Here's 1st gear, and you can see the switch is clicked or in it's CLOSED position.

      And here's the finished product inside:

      Pretty straight forward install, just time consuming. I just leave it in low boost driving around to save gas. Also with the part throttle spikes you may see, it's not as bad when it only goes to like 11psi instead of 20+. Then if someone wants to play, I switch it to the right, the II symbol for all high boost. And then when I go to the track, I'll switch it to the I symbol for low boost in 1st to help with traction and then it'll go right into high boost upon shifting into 2nd.
      I tested it all out and now it's just a matter of tuning the boost levels, more so the low boost for 1st gear. Very nice upgrade to have, especially if you're used to flooring it on open roads and also hate filling up every 4 days.
      If anyone is interested, the switches were sourced from Mouser Electronics online...www.mouser.com. The part numbers are as following:
      3-way Rocker Switch : 612-R5DBLKBLKCF0
      $3.15
      Snap-Action Switch : 540-E21-50K
      $6.46
      Go check out Boostvalve.com and tell Ric you really want this new setup. [IMG]http://**********************/smile/emthup.gif[/IMG]
      One last thing to add: Even if you do not plan on going with this extravagant of a setup, Ric provideds EVERYTHING you'll need for a low/high boost setup. The switch, DIRECTIONS, wiring, connectors, hell even the zipties are included. He'll hook ya up! I was a satisfied customer when I bought my first boostvalve for my GTI, and now I'm satisfied 10-fold with this new dual stage.
      Cheers!

      awesome writeup [IMG]http://**********************/smile/emthup.gif[/IMG]
      the 1st gear switch looks kinda fragile, like if it could slip if you don't engage consistently.
      The install looks perfectly clean [IMG]http://**********************/smile/emthup.gif[/IMG]

      great write up and product! I am running the stage2 for 1 1/2 years now without any problems. I just wrote Ric an e-mail because I want to upgrade my old style installation to the new block version. Looks much cleaner. [IMG]http://**********************/smile/emthup.gif[/IMG]

      It does look that way but as long as everything is tight it works everytime. But if it WOULD miss, all I have to do is pop the shifter cover, turn the assembly a lil and retighten the bolt. No problem.
      Tizzle, you know how I do.

      nice find on the WOT switch, i know many companies put their logo on them and sell them for 35+ when they are on there for 3-6$.

      Yes they do! Got their catalog and it weighs probably 10lbs! Enginerd pointed me in the right direction on the 1st gear switch, just looked one up in the catalog and ordered it lol.
      So far, the drag setup does like it should every time. Switch is working perfect. Was driving home from my buddy's house tonight and thought of something that needs changed...I wanna find a 3-way rocker that will illuminate red, and rig it to the dimmer switch. I think it'd be cool to see the I, O, and II lit up on that. I don't want just a whole switch lit up, just the letters. The search begins

      Looks good. [IMG]http://**********************/smile/emthup.gif[/IMG]
      Pretty funny how first can only hold 12 psi before you break the tires loose.

      It holds 10-11 in first (low), but as soon as it hits 4k rpm, it rises to 16 or so. It's b/c the WG rod is cranked and it wants to hold 15 at redline so it's pretty nice, get some extra boost at the top of 1st.

      I'm sure you can use more than 11psi in first gear....
      What tires are on there?

      Very nice, only thing I would change is the location of the switch.
      I sold my bagged VW and bought a 5.0?

      Nice spot! I actually wanted it to be as close to the shifter and as accessible as possible while still looking OEM. That way you just drop your hand off the shifter and tap the switch ya know.
      As for the 11psi in 1st, that's only down low. B/c the WG is cranked, it holds 15 at redline so once I'm at 4k, it's at 16psi, not 11 anymore. We'll see but so far looks like I'll be able to about dump the clutch and not spin out. [IMG]http://**********************/smile/emthup.gif[/IMG]
      Oh and they're the OEM F1's right now. When I drag on go the 16in steelies with Falken Ziex 512 tires...not sure on the measurements.

      Yea, your switch is really easy to get to. The ones I put in are easy to hit, but sometimes I need to pull a CD or junk out of the way. My switches aren't for boost, so I didn't need them as prominent (you can't even see them when sitting).

      you are the man, very nice install and writeup. thanks for the part #s for the switches, this is something i'll be doing in a few months after i install the k04-20 among other things.
      two for you!

      Gracias! I'm still looking but if anyone knows where to source a 3-way rocker that looks exactly like the one I used, but will light up red, let me know. In daylight it looks like an OEM switch because the white and the font of the symbols resembles all the switches on the dash. If they could light up red like the dash, perfect at night!
