Un-Official Mechanical Boost Gauge Peak/Sustained Boost Registry

[shagghie]

Now that we have some real mechanical boost gauge options out there, I'd like to start a thread that simply logs people's peak and sustained boost levels that they are seeing, along with any hardware/software mods that would directly contribute to those numbers and the turbo model (1446, 1448, or upgraded X)

Example:


21 Peak
19 Sustained
Turbo: 1446
HW Mods: CAI, BOV, WGA, FMIC, Check Valve Mod, etc.
SW: MM ECM Setting #2

Hoping this will get us some benchmarking real-world boost levels, and also help tell the story on how much boost is leaked by the stock SMIC plumbing, the evac system, etc. And then also be able to see how the ECU reacts to HW/SW mods, too. I'd kick us off, but haven't installed my ATM BG yet!

Nice reference, thread stuck for ease of locating it in the future.

19.7 Peak
19.7 Sustained ( i think at least)
Turbo: 1446
HW Mods: HCI CAI, Check Valve Mod, RRM Hi Flow DP (wrapped with titanium heat wrap)
Data System: Torque Pro
Gear used: 3rd and 4th
Octane: 92
Elevation: Unknown but the ocean is only about 3 miles away

Now i did see sustained PSI of 19.9 when I was catless with peaks in the 20.?? range maybe even higher. I have not tried in 1st or second gear while logging with ESC off and may see a higher PSI.

I added data system used for logging and what gear the pull was in.

I was going to start a thread like this!!Thanks Shagghie

24 Peak
24 Sustained
Turbo: 1446 ( I have an early 2012 model so I believe I have this turbo)
HW Mods: Injen CAI, Forge BOV & WGA, MPx TB, ATM BG
SW: TMC ECM Setting@8
Elevation:9ft
Octane:93
Gear used: 3rd , 4th, and 5th

Ill update my reply as some time goes by and as well once I add more Hardware! Oh yeah lets see some numbers!

I just had my car on a dyno and we pulled boost as well so I will post mine.

22 Peak
20 Sustained
Not sure of turbo and I'm not near my car.
HW Mods: Injen Intake, Forge BOV & Actuator, Ryephile EVAP Reroute, MPX TB & UD Pulley, RRM High Flow DP, Magnaflow Catback
SW: TMC Box on 9

I will be putting a new box on this week as well as a couple other things and installing the ATM Boost Gauge. I will update once done.

[NORCAL SS]

you guys should include elevations.

[n00dle]

should octane too.

22 peak
21-22 sustained
Turbo 1446 (MY2013)
HW Mods Eurocompusion R3T V2 CAI, ATM BG
SW Mods TMC box setting 6
Octane 91
Elevation 300 ft

I have the check valve mod waiting to be done, and my TMC catless DP is being installed tomorrow. Will update with new results.

Thanks! Time to turn off the speed limit indicator

they all have a gt1446 model number but there is more than one part number that lists as that model. the newer ones have a different a/r ratio on the intake housing. no real difference. just a different/newer casting.

Had something interesting happen to me yesterday. I was ringing out fourth getting on the freeway and at about 5500 RPM my boost suddently cut back from 22psi to 18, it was somewhat jolting. Im 90% positive i was only at 5500 and not about to kiss redline. Could the knock sensor have kicked in? Or does boost start to fall off at this RPM? I didnt have enough space to replicate it yesterday but ill try again today.

Aside from the TMC and de-cat downpipe, do you have any other mods? Pedal Booster or GoPedal?? Anything like that?
