Good place to tap for a vacuum source for EBC/Boost Gauge/anything else

[blackdragon0731]

First of all, I don't know if this is exactly the right section for this post.

Secondly, I haven't read this ANYWHERE on this site so I figured I'd share, if I missed it someone let me know.

After doing some reading and looking around, I've come to the conclusion that for anyone wondering where a good place to tap for a vacuum source, for installing gauges or an electronic boost controller, try putting either a single tee (if you only need one) or even using a vacuum manifold in-line with the brake booster vacuum line. That's a pretty damn strong signal and there should be no reason that teeing into it properly should do any harm, just make sure you splice it in before the check valve in the line (that should be no issue, the check valve is pretty far back).

I'm going to be trying this on this upcoming monday for my GReddy EBC so for anyone wondering how this works just stay tuned

For anyone worried about possibly causing a leak in the line and losing braking, just remember the brake boost is an ASSIST and merely assists the braking action. The check valve in the system keeps enough pressure to allow you brake normally until that retained pressure is lost, but you can still brake!

If this is deterring you, there are already a few points in that vacuum line that are coupled together from the factory, with clamps and everything, you can merely replace this inline coupler with the T-piece you want to use and reuse the factory clamps and everything, you should have no reason to have any vacuum leak.

EBC = fail on this car, IMHO. There is no way the EBC can read load and make the necessary adjustments to keep your engine safe like the full capabilities of an ECU, either stock or with a sensible tune. That's the same problem that MBC's have. Yes, you can set boost and control boost, but you can't read load. Consider a tune. AP, Standback or at least the Hypertech, which is a nice, safe way to build power without going zoom, zoom, boom. And please run your BPV in full recirc.

It's in my sig, running on a Cobb Protune.

I'm running the EBC and a Cobb Protune on the AP. I know to run full recirc, but running a tune and being able to adjust all sorts of parameters running a hybrid BOV won't hurt a thing. I definitely don't run VTA, I know that you don't do that on a MAF metered car. But running an EBC and keeping the numbers sensible for this turbo setup won't be putting me in the zoom zoom boom club. If anything I was getting more boost creep and funky boost targets running the Cobb out of box maps than I am now.

EBC will get me a one way ticket to the zoom zoom boom club when I start overboosting, which would be obviously stupid of me. I keep my boost levels sensibly over stock, well within the range this turbo can handle, and have had it properly tuned by a professional. If he wasn't worried about it, then I have every confidence in him that my car will be just fine, especially considering they tune MS3's regularly.

If I wanted to properly read load/boost and make necessary adjustments I'd go with a true EMS and have it tuned on that.
