My original vacuum location was the brake booster vacuum line, which comes right off of the intake and goes the master cylinder. it should have worked pretty well, BUT my gate was being ornery, so I moved it to right under the TIP sensor, since there is a 1/8 NPT threaded hole on the EcoPowerParts pipes in that location.

Brad used the TIP line itself, which is pre-intercooler, and also pictured earlier in the thread. It is a stock reference on the pipe from the rear turbo to the intercooler, which should help with the gate opening since it would have a bit more pressure than any post intercooler references.

IMO, I would ask him to be sure, but would start with that reference. You can run a T off of the stock line back to the charge pipe, and then out to your gate.

As for the gate, is that a knock-off F38? Looks to be, so you should be able to buy TiAL F38 springs for it (I assume its a 38mm), unfotunately you are looking at ~$30 per spring, so make sure you know the gate works first. Would test with the 13PSI setup you have first to make sure the gate opens and what not.

Just realized from looking at wastegate springs , half of what you pay for with wastgates when you buy name brand is the assortment of springs.

it is a knock off, not sure of which one. i figured that not being near the heat of the exhaust it really wasn't that big of a deal to not go top of the line. brad and i have talked about reference line placement and decided it should be off the manifold not off the rear turbo tube like everyone else is using. because i plan on dialing the waste gate in with an mbc rather than buy new springs. gonna try this to see if i can get a consistent result first. if it doesn't work then i will regroup and figure out what springs i will need to buy.

i looked last night on the actual intake and didn't see a good spot to attach a reference line directly from the manifold. that is why i am asking about the reference off the tube i posted above. i can weld it myself so it wouldnt cost me a dime.

Brake booster vacuum line for reference. Z

[derfdog15]

For extra reference for anyone interested.

As ZSHO/Myself Have Mentioned in the past/this thread, the vacuum line for the brake booster uses a 3/8" hose, so if tapping that you need a T with 3/8" barbs to insert.

The TIP reference on the piping from the rear turbo to intercooler, uses 1/4" hose, so you would need a T with 1/4" barbs.

For the wastegate itself/ most wastegates/most BOVs they recommend 1/4" hose as well, and that is what the supplied nipples usually support. 6mm hose works as well.

f8tlSHO, my only concern with that location is that with the gate open, it may be too close to the gate and have a pressure drop causing the gate to chatter/oscillate between open and closed. But go ahead and test it out if it isn't too much trouble for ya, would definitely make line routing super easy.

Even easier to take the car in for service. Pop off put noise thingy back on, done.. I just drilled and tapped a hole in the pipe. I will attempt this and see how it goes

Great overall Discussion by far,sticky anyone?  Due LMK. Z

Slightly off-topic (as I tend to do), but I'd just like to say that I REALLY appreciate the ingenuity of people on this forum and their willingness to experiment and collaborate.

I would be more than happy for this to be stickied if you see it fit!

For sure let us know how it works out/post some logs if you can. I am also interested to see how the smaller combination of springs + MBC using the actual pipe as reference will work out. I assume you are going to use the same port, or another on the same pipe for the MBC when that happens?

I enjoy the tangents! And wholeheartedly second that this forum is great and full of quality people. Glad to be a part of it.

Derfdog15 the port will be used to run to the mbc then to the gate. Only 1 port needed. I will definitely post results and logs for the masses. I still have to get a 1.5" hose to connect to the noise thingy port. I have the tune already from bradley. It snowed here last night, so I have to wait till the roads are all cleaned up to do a "full" log.

Got it! Good luck. Also for reference, I bought 1.5 feet of hose from Autozone the other day, they apparently sell it by the foot from a 50 ft. roll. It was only $1.59 per foot plus tax, and the guy cut me 2 ft and charged for just one. Pretty awesome IMO.

I was looking for a boost reference line directly off the intake ( not intake piping) didn't see anything I could use....

I am putting the wastegate on, was wondering if I could just weld a fitting right on the tube attached to the wastegate. See picture, where the black dot is. Just wondering if this would be good or bad being so close to the wastegate

Interesting flange interfaces on that guy, particularly the connection to the bottom aluminum housing that contains the diaphragm. If you end up with any leaks, maybe consider reassembling with some RTV and thread locker on the screws.

While I wouldn't try using that in a traditional application, it may be just fine in this (much) less severe environment. Definitely interested to watch this evolve.

Do you have additional pictures or a link to the gate you bought? Curious if my idea for a Tial preload adjuster might work for this one as well. If so, might be a less expensive alternative to an auxiliary MBC. Could you take a couple of pictures of the internals as well, when you get a chance?

I believe it a replica/similar design to the TiAL F38 which is the predecessor to the MV-S MV-R line. The two bolt flange was the design practice a little while ago, then Vband took completely over.

Here is the F38: http://www.tialsport.com/index.php/tial-products/wastegates/40-f38

Here is the gate he has, I believe: https://www.amazon.com/External-Exhaust-Manifold-Wastegate-Silver/dp/B00N1B66P8/ref=sr_1_2?s=automotive&ie=UTF8&qid=1483726767&sr=1-2&keywords=38mm+wastegate

here is a precision 38mm gate using the 2 bolt(i think it their current 38mm gate): https://www.amazon.com/Precision-Turbo-External-Wastegate-SPRINGS/dp/B00BNAJNA4/ref=sr_1_1?s=automotive&ie=UTF8&qid=1483726767&sr=1-1&keywords=38mm+wastegate

Precision uses a V-band on the rest of their gates, but 38mm retains a 2 bolt AFAIK.

Nice thing with the two bolt is that there are readily available flanges in whatever material you want, and easy to buy dump-pipes etc. such as: https://www.amazon.com/Rev9Power-Rev9-AC-004-38mm-Wastegate-Dump/dp/B00SA3PLEO/ref=sr_1_3?s=automotive&ie=UTF8&qid=1483726767&sr=1-3&keywords=38mm+wastegate
