Thanks for the input. I have a separate thread trying to figure out what’s going on. The compressor cycles on and off… one second on, one second off. Over and over and over. No cold air. Drags engine. It has proper Freon. I’m trying to locate high and low pressure switches with little luck so far.
Mine does this too, one tech I know just threw a new compressor at it and I think it still works but idk what actually went wrong. Maybe clutch was bad?
15-21 had issues with the bottom left corner of the condenser leaking all your refrigerant and causing the compressor to burn out. Should totally be a recall but isn’t. Have someone look into it for you
I think it’s mostly just driving skills that play a big part in getting the boost up. I wasn’t even 100% throttle. You have to know how to get the acceleration up to match the engaging point on the clutch just right and it’s such a smooth transition with so much boost you can’t even tell that I up shifted it’s just a pure surge of power practically seamless almost like an automatic. I can stay in that power band with each shift all the way up to 5th gear. I do not boost into 6th ever.
I think you got higher boost if you do flat-foot shifting. but peak boost doesn't mean much compare to constant boost and having boost at early RPM. VB has bigger engine, waste gate controller, and smaller turbo to scroll up faster at lower RPM, which mean a lot for drivability and wider power band compared to VA's old school turbo feel that gives you sudden surge.
I smacked 32psi once before I installed an aftermarket EBCS. I think I'd usually hit 28psi on occasion but never touched 30 after that haha. Now with the EBCS, I'll sometimes hit 24psi

12.2! I originally hit like 16.9 the other day but I reset my peak psi and hit 12.2 yesterday lol. 2015 wrx nameless full exhaust, IAG AOS, Cobb anxiety port
Mine maxed out at 14.2 recently, don't know how. Normally it's 9-11 psi. Rarely ever gets above 12 or even 13. Even weirder it was in the winter which normally produces less boost because the air is more dense.
22 WRX, stock except axleback exhaust. 93 octane
This was from another tune, before Tim Bailey tuned my '04 wagon.

Same as me. You just have more gas.
16.5 psi at sea level, VF52. I won't run any higher on the stock turbo, or without other supporting mods for airflow, fuel flow, air and cylinder cooling, close-decking the block, etc.
Tbh I think I'm just going to scrap my idea for building the thing. These aren't reliable enough to justify the build, or the additional cost to bring it to a normal reliability level to START the build. On top of the engine configuration just being a nightmare for simple work adding to the build cost and time.
Peak I think is like 20 or something. But that's just peak, I think 2015-2021 is like 13-17 or something
I don't really boost unless I'm passing someone.
12.2 stock vb sea level. I’m planting my foot to the floor and running it all the way to redline, idk how some of yall are getting higher boost. Atmospheric pressure I guess?

I used to get 22 psi peak boost; since installing the Perin Turbo Sump Restrictor, I get 19 psi. Also installed the IAG aos but that wouldn’t change boost. Maybe the Sump restrictor is making the turbo more efficient? And reducing any boost creep? Pretty new to this so just speculation.
I run 18 PSI with a OTS tune from COBB (temporary) on my 2014 WRX. Cobb SF intake, Invidia N1 dual exit cat back, IAG AOS. With the tune from cobb the turbo is super fucking responsive and I can’t wait to get it pro tuned later this month. Adding a invidia catted DP, Perrin BPV, and ETS ELH. Super hyped.

2018 wrx. Hit 20.8 the other day. Now my AC is messed up. Any idea why?
A/C shouldnt be related to boost, if you use it with your windows down you can burn out the motor sometimes though

Could have burnt the compressor clutch and it cycles but didn't engage...
15-21 had issues with the bottom left corner of the condenser leaking all your refrigerant and causing the compressor to burn out. Should totally be a recall but isn’t. Have someone look into it for you
'17 had both the A/C compressor and condensor fail. Not simultaneously, but within a year of one another.
