anyone tried in-cockpit hallman mbc?
I was just wondering, instead of purchasing the adjustment knob thing, couldnt you just run the tubing into the cockpit and install the mbc either in the dash with the knob sticking out or behind the glove box or something? it would solve the issue of getting the attachment or getting an ebc. Is that possible or is it just me?
If you run a MBC with long vacuum lines into the cockpit...it will work like crap. You will get very very big boost spikes becuase the signal takes so long to get to the controller, then to get back to the wastegate. Im talking spikes of say 8-10psi.
The hallman evolution works great as an excelent comprimise of manual controller simplicity and in car adjustment of EBC.

yea thought of that... but do you really think it would be that dramatic? So by that theory my boost guage is off by a good amount too?
p.s. I dont think I'd hear the vaccuum, the boost guage vac. line goes right up on the steering wheel, by my head. (at least I dont think I would)

Trust me you will hear it.
FYI, Hallman makes an in-cockpit controller for an engine compartment mounted boost controller. I'm not sure if this is the same thing that you are selling or not stevevo8. I had a a hallman mbc w/cockpit mounted controller in my last car and it worked flawlessly and had no noise assoicated with it. The vac lines and the mbc itself are in the engine bay as usual, but he runs a cable to turn the adjustment screw into the cockpit and mounts a knob on it so you can adjust boost from inside. Worked well for me.
I have the Hallman Evolution MBC which is the one that you can adjust in cockpit. No problems at all with it. It is routed through the gormet on the passengers side and attached to the passenger side next to the shifter

your boost gauge works differently becuase it's a static pressure / no flow situation.
the boost controller has twice the distance of line as your gauge plus it is not a static situation.
