Alright guys, I feel like such an ass for posting in the newbies forum, but I didnt think this belonged anywhere else.
I hooked up my MBC like I do in every other DSM I have ever owned, from the nipple off of the turbo "J" pipe to the input side of the MBC, then the output vaccuum line from the MBC to the wastegate.
It works awesome, and this is how I have been doing it for years. However, I just picked up the AMS kit (until my profec B can be bought) and the directions have the boost source coming from the BOV line to the intake manifold. (Where my boost gauge is tapped).
Now, here is the question, am I loosing out on anything by hooking it up the direct route like I did above instead of the BOV route. The reason I am asking is that line creates vaccuum, so does the MBC need that vaccuum to open and close the wastegate with more precision?
Obviously if I only hook it up to a nipple off of the turbo then there will never be a vaccuum source. My boost hits 15 psi faster than a raped ape, but tapers off to about 11-12 psi by 6k or so. Would hooking it up through the BOV line remedy this problem and keep me at a solid 15psi? I dont think it would, and I havent checked for boost leaks yet, which would definately contribute to the loss of boost at higher rpms...
Just thought I would ask to see everyones opinion, im guessing a boost source is a boost source, nuff said. The reason I have always hooked it up to that little nipple is because that is the fastest possible way to get a boost source (right off the compressor) which would hopefully actuate the mbc and wastegate faster and with more precision...I think so anyways.
Would the mighty car gods that invented ball bearing turbo's and titanium retainers please chime in...
