The right way to hook up MBC ????

[lilpastrana]

I pulled out a engine and dropped it into a body that had a mbc. I don't know where the vac. lines are supossed to go. Pictures please !!!

Tap the vacuum line going from the nipple off the compressor j-pipe to the wastegate actuator. So it should go:

Compressor pipe ======> MBC ======> wastegate actuator

Do not tap into the BOV line

Yep he is right do not tap through the bov. Actuator to MBC to j-pipe.

 

[lilpastrana]

what is the j pipe ? and there is it ?

 

[JayRolla]

It is the pipe shaped like a j coming from the turbo. It connects to the lower intercooler pipe. There is a small nipple with a vaccuum line connected that runs to the actuator on the turbo.

It's called the compressor outlet elbow. The J-Pipes are bought from Slowboy Racing and other companiesand re-rought the air to be able to run a FMIC setup on a 14b or 16g.

I have a question, when I had mine hooked up to the compressor it would spike to like 21psi and then SLOWLY calm down to 17ps. When I tee'ed it to the BOV LINE it spikes to 18psi for a second then holds at 17. I fully understand what you guys are saying but am curious as to why my set up seems to work better?
