Just along the lines of this thread.......

Where is the best boost source for a boost controller. I have my forge MBC sourced of the same line as my BOV. I have seen others use the nipple by the tubo. Is there a difference?

thanks alot it help alot!!!

the buttom fitting off the MBC goes to the turbo nipple or you can tee off to the BOV line then the other fitting off the MBC goes to the wastegate nipple.hope tha makes sense.Or go to LANCERSHOP.COM then go to how to install.

There seems to be a difference of opinion.

If I was running an MBC, I would use the turbo nipple method
instead of the BOV method.

However I use an Xede, so I don't use either method.

Are there any notable pro's or con's to each method?

I had mine T'd to bov line at first.
I was getting incorrect boost readings but spool up was slightly faster.

This past week, I connected the boost source directly to the turbo nipple and I get correct readings on boost levels but the spool up is just a tad slower.
I am tuned on 22lbs of boost BTW.
When I had my line T'd to the bov, I was getting a reading of almost 25lbs of boost which freaked me out at first but after I connected directly to the turbo nipple it reads correctly @ 22-23lbs peak.

It's a very simple install either way you do it.
Just takes some time and patience.

I've tried it both ways. To be honest it really does'nt make any difference. Right now I have it "T"ed of the DV line.

1. for ease of routing the vacuum lines
2. Boost felt to be a little more consistant this way

To be honest though eiather way works fine its up to you

Man there is a lot out there on this.

I personally used the how to on Hallman's site and there is a link to it posted above. It is BETTER to connect your MBC to the nipple on the stock LICP right by the turbo outlet for two reasons IMO. One, you wont have any pressure drop through your FMIC and piping from the turbo outlet to the boost source. This could be why some people get incorrect boost readings. And two (the most important) it is better to have your boost source as close to the thing that is actually making boost as possible. Think about it. If you had a leak anywhere between your turbo and your new boost source (ie your BOV to mani line) then you could be reading 22psi and the turbo could be pumping out 30psi. Now I had to run off of that line because my Buschur LICP does not have the nipple but if you are still running the stock LICP then use that nipple as your boost source definately. Hope this helps.

You guys keep talking about innacurate readings but that doesnt really matter with a mbc. A mbc doesnt take any pressure reading and when setting it you should be refering to your boost gauge that is hopefully sorced from behind the throttle body.

it made a difference on my car.
When I had it tapped to the bov line, my peak boost was almost @ 1.7bars.

Now I have it connected to the turbo, it does not read over 1.5bars (close to 22lbs).
I really don't know why it makes a difference like that but it just did on my car at least.
