Some updates below (though I'm no more certain of anything than before...). Also, I want to point out that I'm not trying to talk smack about anyone here. I wouldn't have bought Sai's kit if I thought it wasn't going to be a solid choice.
Sai indicated that there are instructions that can be...
Thanks for the reply, Terry!
AFAIK, there are no install docs for the Sai Li Triple Pump Return system (I think it's new whereas before he only had the modified GT500 option). I have emailed the company to be sure though.
That said, I was using Lethal's return diagram as a basis and they...
I've seen a few articles talking about losses due to line length and how a larger diameter line will have a lower loss.
What I'm asking about here though is whether the restrictions at the FPR will have a negative impact on the system? My guess is that it will.
In the case of a Y-block you...
If you were to run -10an lines for the feed and -8an for the return, would using a FPR with -6an ports all the way around be... less than desirable?
One of the kits is setup this way and I would've thought it best to try and match the actual line size. I believe that reducing the size at the...
Does anyone know the size of the nipple/port on the back of the 2018 intake manifold that goes to the IMRCs?
Is the circled portion below a 3/8" ID or 1/2" ID hose?

To continue my virtually one-sided thread, it seems Occam's Razor wins again...
GFB suspects that the internal MAP sensor in the G-Force III head unit is bad.
I'll confirm here if it fixes the problem in the event that it's helpful for anyone down the line.
I swapped out the WG springs last night to a combo that yields 10.15psi and made sure all plugged ports were nice and tight [hey now!].
Currently, at the lowest duty cycle setting (10%), the ebc peaked at 8.6psi. I also datalogged with the X4 and saw peak load of 1.65. Inferring from what...
Small update: I set the duty cycle to 65% and did a 7400rpm pull. Boost controller peaked at 6.5psi. Something definitely isn't right.
It seems like it's only using WG spring pressure (5.8psi), I guess with a little overboost? That doesn't make sense though as I checked the plumbing...
MyLilPony When you got the wastegate setup working, did you find that spring pressure was equal to boost or half? I'm seeing both thrown around and not sure if this is also playing a factor.
I would love to be able to trust the values reported on dash but regardless of whether or not that's possible, I need to be able to rely on the reading from the electronic boost controller. I pulled the bumper again and verified everything mentioned above. It all seems to be per the...
Thanks 96gt4.6, for the confirmation on the readout.
Guess I'll be pulling the bumper to check everything one. more. time. :headbang:
Let me know if you happen to have suggestions of what else to check. Current plan is as follows:
Verify no kinks or tears in hoses and that all are still...
Thanks for the great discussion so far everyone. I thought about adding a mechanical gauge but there are some potential cons as well:
The obvious... buying and installing yet another component. Not the end of the world but it's already getting a bit cluttered.
If the ebc isn't reading properly...
There's a 1/8 line directly off of the controller which taps into a manifold vacuum source. The 3-port solenoid is connected per GFB's instruction for external wastegates (see pic below).
Forgot to add, the boost source comes via hose barb tapped into the "hot pipe", just above the WG which is...
Anyone notice a significant delta in the boost readout from the dash versus either gauge or ebc? I'm not expecting the 2 to be dead nuts, but they are quite a ways off. See below...
For reference, I'm running a StageII Procharger kit pulleyed @ ~15psi. Since I'm running pump (91), I added...
Small update: Installed GT350 tube w/MAF relo as well as replaced as replaced the spring diaphragm on Tial Q BOV.
Waiting on SCT Tuner and MAK Hurricane Pipe which are both en route.
Needs a tune but BOV is confirmed open at idle so that's good news. Hopefully it's all good after the tune...
So I revamped my diy smoke tester and still didn't see anything. I figured I shouldn't leave it to chance so I bought a premade and still no visible smoke coming from any vacuum lines.
It definitely seemed like a feasible scenario but I would've expected to see a leak if there was one.
Thoughts?
Smoke test was inconclusive. I don't think the volume of smoke making it through the system was sufficient for leak detection. Going to modify the DIY tester and try again, this time after pulling the front bumper so I can put eyes on the BOV.
The Procharger rep gave a rough rule of thumb of 1psi per 100mils/0.1" in pulley size. If that is indeed the case, then either the 4.63" on the low end or 4.5" would theoretically put you into the range you are after. (Assuming 6-rib based on 4.75" which isn't offered on the 8-rib)
