mbc,bov,ex wg, boost vac gauge hookup

[dsmreck]

damn I just rerouted the boost controller to the upper intercooler pipe tonight. This is the reason I asked this question, because it seems everyone has a different perspective on how to hook this up the right way. I didnt drive it or anything, but I did put the 1g bov back on and now I have a bov that actually works again. As far as using the side port i've got that hooked up. To my understanding the top port is to keep it shut longer. i.e. 10lb spring plus pressure in the top equalls >10lb spring.

With an MBC, just use the side port and leave the top port open so that it can breathe. You never use the top port by itself, the top port is usually used with an electronic boost controller.

Most people run stockish turbos off the compressor outlets and bigger turbos off the intake manifold. The best spot would actually probably be tapped into the upper intercooler pipe, right before the throttle body, but you rarely see that. In that spot you would have close to intake manifold boost readings(which are better than the ones coming right off the turbo) and then don't have the vacuum of the intake manifold.

It really doesn't matter a huge amount though.

Ok starting to make sense except with a gm maf do i want to tie in before or after the maf.

[Shane@DBPerformance]

MAF has nothing to do with it.
