I really could not believe what I was reading! If you think for 1 god damn second that you have ANY other issue for not hitting 24 psi. Then you sir are living up to your screen name. Not only that, but if you think a stock TMIC is efficient enough for a GT30 size turbo, you have literally got to be one of the most ignorant people on this forum!

Op, I dont know how else to put it other than this.... Get a big TMIC or a FMIC! NOW! and stop what you are doing! You WILL blow this engine to pieces using a stock intercooler! The thing was made for a tiny VF39, how in gods name do you think its fine for a GT30????

uhhhhhh, the stupidity in this thread has me raging!

P.s Leave the wastgate ALONE! there is nothing wrong with it, and NEVER EVER wire it shut!!

Oh, and you do realize the wastgate opening at any time after 14psi is normal. Ever thought of EWG's?? They open at spring pressure.... to relieve excess pressure that can cause over boosting. Ive got a 38mm EWG on my car currently that is set at 14psi. At exactly 14 psi it opens but I run 19psi. It was tuned for 22 but we brought it back down. I still ran 22 psi with no issues

The wastegate will open, thats normal, a tiny little leak before 14psi from it also is NOT going to hurt. Many people run 8psi springs on a 24psi set. Im guessing you are under the impression that the WG opens at 22psi or at 24psi. Thats not how it works....

Get a intercooler that is efficient enough to do what you are doing, not only that but a stock TMIC can not efficiently cool the incoming air of a GT30 turbo. YOU WILL blow this engine up if you continue to do what you are doing.

-I run Meth, I appreciate your concern.
-I'm aware the STI TMIC was ment for a VF39 + other STI turbo's.
-I know its not an efficient Intercooler, FMIC is the way to go.
-Wiring the Wastegate shut should yield me infinite boost. The fact that its not is not right. I did this for ****ing test purposes.
-I understand how a Wastegate works.
-This wastegate opens at 12 psi if left without a MBC.

UK-Wagon, don't be a douchebag. Don't jump to conclusions. If your going to read certain lines then yes, I'm pretty retarded. If you took your time, I tried explaining the steps I took to try to figure this out.

At the end of the day, if a new tmic or fmic will yield me the possibility of going above 22 psi then I'll upgrade. I don't think this is my issue. I'm sure I'm restricting the turbo somewhat but not to 22 psi limit. Again, yes the TMIC is not very good at cooling the air down, my meth kit does a wonderful job though.

Then why install a GT30 turbo and still use it expecting good results?????

Op, are you Trollin? Im beginning to think you are, and if so... you won, I lost hard! LOL

ATP says the STI intercooler is not the problem. I also did a pre intercooler boost test and it came out to about 22psi.

Yeah but what would ATP know, it's not like they built the turbo or.... oh wait, yes they did.

And if the TMIC was the problem then you'd see more pressure upstream of it than downstream of it. Same pressure on both sides means that it's not causing a measurable pressure drop.

Small TMIC + meth seems like a reasonable thing to try, in terms of overall charge cooling. When the boost issue gets sorted out, we'll have to compare logs to see what the pros and cons are of your TMIC+meth vs. my FMIC without meth.

Sure!

Just waiting on ATP before I try the ultimate test.

Gone to do the ultimate test.

Took the inlet off (completely). Went for a run. The ****ing car has balls!

So the inlet is robbing me of everything that's power related!

God it hauled ass. 25psi no problem in first gear. So much torque!

Time to make my AMR inlet work. Lots of work ahead of me.

Interesting, I would not have guessed it mattered that much. Which inlet were you using?

Also, are you running blow-through MAF, or SD, or what?

Using the stock 2.4" inlet (I believe I stated that earlier). Running a MAF, I had to unplug her for the test.

that is pretty interesting...i haven't had any issues like this when tuning a larger turbo with 2.4" inlet setup, but then again, they have ALL been aftermarket silicon inlets with aftermarket intakes so...maybe the non-smoothed path of the stock inlet and intake and the fact that it is 2.4" are compounding together. this is a pretty interesting and very helpful find for future reference.

It definitely felt aggressive. Went from 18 psi in first gear to 24 psi. Sucks that the inlet is going to be a pain in the ass to install (header/up-pipe shifted the turbo to the left by half an inch). Ohh Well, Gotta figure it out!

What did your turbo inlet look like when you removed it? Was it kinked somewhere in the middle... like maybe it had been sucked in on itself? I would have a hard time believing the 2.4" inlet was that much of a restriction. Not disagreeing its a restriction, just not that much of one.

No the turbo inlet was not kinked. It looks normal.

I'll make a log from a 1st to 4th gear pull with the stocker then with the 3" inlet. I have to put the stocker on first as the uppipe needs to be slightly modified to help me allign the 3" inlet.

Well, after a full day working on the car, modifying the up-pipe so that the AMR inlet fit nicely on the turbo, welding, bs, yelling, more bs etc it was done.

We had to modify the dp and didn't have any J-bends to complete it so we ran an it open. Car sounded awesome

Went for a spin, wastegate unplugged and the car only made 22psi in 1st to 4th then 25 psi in 5th. It was definitely better then the stock inlet which would have been 18 psi in first, 20 psi in 2nd, then 22 psi 3rd to 5th. So yes an improvement though not as good as the 25 psi I got in 1st without any inlet on the turbo.

I wasn't driving the car but it seemed to have more go for sure (with 3 people). I removed the stock filter and gained about 0.7 - 1 psi in each gear, did this just to make sure that wasn't the restriction.

I'll see what ATP says about this (they say the STI TMIC is not a restriction, just not efficient). I don't have any more money to fab a FMIC so I'll make due till summer. This is plenty of power for winter time, I'll try my BOV to see if the BPV is leaking to rule that out.

When I get the car on Tuesday with the Fabbed up exhaust I'll record a 2nd to 3rd gear pull to compare against the 2.4" inlet.

BOV helped, I can do 1.7 bar in first gear and get it to 2 bars afterwards. So it was a mix of problems. The inlet helped it breathe and the BPV I guess was slightly leaking? I dunno. Leave it at that.
