not very well lit but right above this is the turbo nipple and you may need to use a long screw driver i came over with another hand from the other side and push pull technique. not that hard then route everything up top. i used 10 ft total on tubing cut them even its almost even then shorten after you place your mount but this will give you plenty of room to zip tie and tuck away from hot parts. if you have have anyquestions let me know . then of course go out and test it and set your boost. most will have you start with it at the bottom or least boost setting. 2 turns out for the turbo XS then i endend up with 2 additional turns to get at 20.

 

Your approach might be a good one, I never even thought about getting it done from the bottom..... The connection off the blower rather than off the hose between the intake and BOV is definitely different. The pressure right off the turbo has to be different than the manifold pressure.... I'm almost positive that the pressure losses throught the IC and all the piping must make a sustantial difference. OTOH, it probably does not matter much if the pressure losses are taken into account and the MBC controls whatever boost you set it at. I guess bottom line is what your boost gauge reads and how steady it holds.

Actually, I've removed my MBC now that I have the AEM EMS After all, now I have a $1500 boost controller I guess it works very well, but I cannot tell since the new Greddy gauges are not working all the time... Funny, weird thing. They sometimes work and sometimes not?

 

I am going to hook a a line between the BOV since this is easy to reach and see if there is any difference in the boost pressure or how the boost is maintained . it will be simple to do back to back runs and then i will post my info . hopefully tomorrow if i get off work early. I wonder why the manufactures give such different ways to install it if there is a better system. you are correct about it doesnt matter which side of the pressure system you are following as long as you monitor the total boost , since the boost gauge is coming off the Manifold, there may be a more consistant or even faster responce from one side to the other . i will let you know.

 

Hey fellas,

Can some one help me out....I did the install to the Tee on the directions that SilverEvo8 wrote but I CANNOT get the wastegate to hold more then 11psi...which I know is factory. what can be the problem? I have tried everything to figure out what's up but just cant get the wastegate to get any kind of signal.

1. T fitted to the BOV/Manifold line, connected to the IN on the MBC

2. capped Turbo inlet, intake inlet, both open nipples on the stock BCS

3. Ran NEW line from wastegate to out on MBC.

made runs this entire week to try and get it to boost more then 11psi, but ZERO luck. What can be my problem? I've check all hoses for leaks, kinks, and made sure the MBC was going the right way, but just can't get it to boost anything more then stock. I'm beginning to wonder that not all EVO's will work with the way that you guys have it written??? or am I crazy???

 

which boost controller you have...

If you have a hallman,I had to use the strong spring... the one that comes installed with the boost controller is too weak....I intalled the strong spring and got my 19-20 psi..

Just in case you have the Hallman Pro RX

 

It sure sounds like your MBC is not holding any pressure at all. It's as if it was not even there Maybe it's a weak spring or no spring at all.....

 

 

well i tried the bov vaccum and now im loosing more boost than before........this is crap im going back to the turbo nipple.........oh by the way just to throw it in there....the type s sucks ***

 

afaik you dont want the wastegate to see vacuum, thats why you hook it to the turbo instead of a source that is in vacuum at times.

 

so then whats the verdict........off the turbo or off a vaccum source......????.........im a little curious on why the instructions would say off a vaccum source and then you call and they say something else......thats a little strange.....can any vendors chime in and give us some feed back...???

 

How many pills are in the stock lines between The turbo outlet,wastegate, and solenoid? I read that there is one between the tee and the wastegate and one between the tee and the solenoid, is there one between the turbo outlet and the tee also?
I ran a new line between the wastegate and the outlet for the MBC. I capped off the line that originally went to the wastegate and used the other end that goes into the solenoid for the imput on the MBC.

This works fine but it spikes 21-22 lbs and then settles to 19, I hit the fuel cut off this morning so I presume I spiked even more. This happened while I rolled into her(building boost), When I go WOT from the start I see 21lbs then drop and hold @ 19, so after reading the posts I realized that I left the pill in the line between the turbo outlet and the MBC so this is probably why the spike is so high, before settling. Any opinions on this?

 

I believe that you have the inlet and outout lines reversed check your directions, The wastegate actuator should be connected to your inlet on the MBC.

With the Greddy Type-S it helps with some of the drivablility issues to take it apart and remove the smaller of the two springs that are in it.

 

What do you use to cap off the nipple on the turbo and whatnot?

 

the hallman instructions say to use the turbo nipple as the inlet on the mbc and the wastegate as the outlet.
Not only that but since you have potentially 3 objects (mbc, bov, boost controller) running off the bov line you should experience more lag, as you would if you increased your vaccuum hose length. In addition, the turbo nipple now runs nothing, and so would be optimal to use for the mbc.
