1 little design flaw on this thing that I found today.

Sometimes, if your boost comes on strong enough, the BB can push past the outlet nozzle. Plus, the way most of our MBC's are installed (mine is this way at least) the outlet is pointing down toward the actuator, so gravity can pull the BB out of the main chamber.

What happened to me today was the BB got jammed in the outlet nozzle, keeping me stuck @ 0.65 bar regardless of how far in I wound the bolt. I'm lucky I found it tho cos if it had come out while driving, that could have been a huge boost spike.

So, make sure you dial UP from low boost to high. If you go PAST your desired boost level, unwind the WHOLE thing and reassemble it, checking the BB is still loose and in the main chamber.

**EDIT**

Also, I didn't bother to check if anyone else in the last 80-odd pages had figured that out. If so, consider this a reiteration.

umm not to keen on reading 80+ pages thought sum1 might be able to help, this MBC is from turbotech right? i checked on their site and cant find anything, although we do deal with them at work, if i ring them up and just ask for a 'turbotech manual boost tee' is he gna be like,' yeh mate we got like 50 different types' or is there only 1 type, is there anything unique about it that i can explain to the guy? it uses a ball bearing or something?

lol flame suits alredy zipped up :/

Update, i installed it, took me 15 min, tightened the nut, car runs 10.5 and eventually reaches 11 by top revs. Extremely happy. Just what i wanted. Thank youU!!

hi mate got any pics and instructions for installation ,gauge and controller ? cheers

sorry to bump an old thread but is he still doing the sau deal?

I think on the first page of this topic you will see a picture that explains to you how to install one. Very easy. Im not very good back yard mechanic but i still managed so you will be okay i reckon. If you need a hand, im in west of melb. :banana:

I've got me one of these, but on checking the pipework, I've found the line to the wastegate is T'd off the vac signal line to the charcoal cannister?? Will this work?? What should I do?

Hey boys i just got this today hooked it all up, Pretty good product considering how cheap and easy it is to install. Have a question though when i hit high rev range my exhaust is fluttering and i feels like i lose boost ? Im running around 12 psi - 13 psi at 0.9 Bar. Im not sure if im not used to it and its hitting the limiter or is theres some sort of issue ? This happens when i rip through the gears but when i drive normal its great. The boost is just crazy lol power from no where.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
