Running MBC into Cab

[tuby]

Can you run your mbc all the way to the cabin with enough vacuum line?
Is there any negative things about doing that?

you want to keep the mbc lines as short as possible. If you want to have it in the cab, then you need to look into the hallman mbc and get the in cockpit option.

You want the vacuum lines to the MBC to be as short as possible. You'll have poor boost control if you run them into the cabin. Think about it, the pressure has to go like 5-6 ft to the MBC, then 5-6 ft back to the actuator.

Get a hallman pro problem solved..

You can run the lines into the cab. I have run it on my DSM since 2001 this way. I have the controller coming through the coin keeper right in front of the shifter. I have great control of my boost from the cockpit with my home made MBC. I will post pictures of it if you want to see how I did it.

Yea I wouldn't recommend you running vacuum lines into the cabin. That length is to far for a boost controller. The hallman pro is the best option, or get a electronic boost controller.

All it does is bleed air off. What does it matter if it does it in the cabin or in the engine bay?

I have mine in cabin, would use more reinforced line but it is just a bleeder style mbc so when it bleeds it doesn't care how far away from the waste gate it is but that's my opinion. Reason to run a more reinforced line is if you turn the boost down, you are holding back pressure and if you blow a hole in a vacuum line you will run FULL boost and cross your fingers she holds together.

That is my point of view exactly. Especially for a bleeder type MBC. I very rarely drive my car without constantly checking temperature, oil pressure, boost levels, and a whole bunch of other things because I know if something fails it could be catastrophic if not caught in time.

I would love to see how you did it thanks!

I will snap some pictures and load them up so you can see how I have it done.

Get the hallman evo kit. Your mbc will be in the engine bay while having control through a wire from inside the cabin. I wouldn't trust an ebc. They used to leak around 25psi. Idk about now tho

Out of curiosity, why do people do this? How often are you adjusting your MBC to make this convenient?

I was just thinking on the aesthetic side of things. That is would look cool and I do think it would save you some time instead of walking back to the hood every time.

Hey man it was nice meeting you sorry I lost you on the cruise. Hope I see you next time. let me know if you go again

this + screen with dsmlink and another tune saved, +meth injection switch = +XXXhp.
Great for hustling.. and making stock v8's angry.

 

[tuby]

Multiple people have said it is bad and some people have said its OK. is there anyway to prove if its good or not? I might end up trying and letting you guys know the results

I turn it down just cruising around town , ill run 16psi then at the track first pass I run 18-20psi (making sure everything is good ) after the shakedown run ill crank her up to 23 or so..
I like to hit the cutout n turnup the boost if I need to get froggy around town..pretty fun no more popping the hood for ol pip

 

[2g spyder eclipse]

Yes, it was fun. I am out there every weekend. Most likely tomorrow

I have mine right next to my obd 2 port in my cabin on both of my 2g's. One has a hallman pro in the cabin, the other has a cheap ebay MBC in the cabin... Both work GREAT!! I will normally have my boost turned down to 18ish then when I wanted to play I would turn it up to 24 or so without having to stop and make adjustments before I even race.... my hallman pro I have to let off the gas, make my adjustments and then get back on it again to see the new results, and with my cheap ebay MBC when im in WOT I can turn it up and see the difference in boost as soon as the MBC clicks for the adjustment I made .. that is the coolest feeling ever, running stock boost with your buddy in the car and in the middle of WOT u reach down and turn the boost up 10psi and watch the look on his face priceless ... then they realize how crazy fast your car can actually be

So i ran my mbc into the cabin and i can't tell any different then how it was before. Logically it makes sense to have them as short as possible but i feel no difference

 

[boost97gst]

In theory if you used hard lines that didnt expand then running a regular MBC in the cabin probably wouldnt cause any problems and have minimal boost spikes.

IMO, I would just get the hallman thats built for in-cabin use. Only one line to run in the cabin and its small. Vs running from compressor/boost source all the way in cabin then all the way back to wg actuator. Thats a lot of hose to run. More places to leak.

 

[Pipnorcali]

On the Hallman in cab its not a vacum line that runs into the cabin

 

[boost97gst]

Im aware of that.........
