EcoBoost... How much boost are you hittin?

[kel krst]

Did my first somewhat real 3rd Gear pull to 5500rpm and my Accessport said 27.33psi.
Just curious what other ecoboost owners are hittin,factory or modded/tuned....

Stock should be around 18. Mine, tuned, is hitting 22.

27.33 !?!? Are you sure ?
What are your mods?
I keep 23.5 / 24.5 psi until 5500 rmp, than tapers down to 22 psi at 6500 mm

Mine are pretty similar max out around 24.5 then tapers down to 22ish after 5500. Was this a one time thing or do you consistently hit 27.3??

Bone stock on 87 my car does 20.4 consistently. Feels pretty healthy for a stock car.

I got to 22PSI yesterday doing a 0-60. Time sucked at 6.1 with wheel spin. I have a K&N Drop In air filter, Airaid Intake Tube and Full-Race Intercooler. Not tune yet.

sh*t so is this bad? Idk if its consistent I jus got to about 1000miles on my car so have been driving conservatively but was doin sum data logging so i wanted to do a few 3rd gear pulls and it was between 26-27.33 the 3x. Mods are;
SpeedFactory FMIC
SpeedFactory CAI
TurboSmart BOV
CPE Charge Pipes
Steeda TB Spacer
UPR DVCC's
Tune+ Denso Plugs

Are you guys that are hittn 24psi still running the factory bov and worm clamps still though? Cuz I was just talking to someone from youtube that didnt even know that the factory bpv doesnt hold boost and i forgot who it is but someone does a test where they prove that it doesnt hold boost on a tuned car...

high 24, sometimes low 25. still working on datalogging though.

The factory charge tubing clamps are a known leak point and the factory BPV is a potential leak point, more so as boost is increased. If you're seeing boost spikes up to 27psig and you haven't made any hardware changes since your final tune revision, then either the load targets are set too high or the weather has changed (cooler) and/or a combo of the two.

The best thing to do is talk to your tuner, make them aware of any hardware changes you've recently made and have them adjust your tune accordingly. 27psi is quite a bit for the stock turbo, even if it's only a spike. It seems to me that you would want to turn that down a little bit. At your level of modification a 24psi spike that normalizes at 22-23 and tapers gradually towards redline with 20-21psi at 6500rpm would be ideal IMO.

I hit 25+ peak and average about 24 on e30 this is after oil is fully warmed up right about 85 degrees after about 20-25 minutes of driving. I have hit 26 for peak on e30 a few weeks ago as well.

If you are running 93 that's way too high for boost. It's even high for e30. Not sure about straight e85 though. I'd ask your tuner to review your logs as it could be over boosting which isn't good for a stock block on pump fuel.

It was def cold temps... It was about midnight and was a highway towardss the mountains. Sending the data log to my tuner today! Thanks for the replys!!

I hit 27.8PSI on cold runs (sub 70 degrees), 23-26PSI in between depending on temp and humidity on my setup. The weather has been crazy erratic here in MA this summer/fall 72 degrees one day, 84 the next etc.

I agree if that is stock no matter the octane you are running sub 100 octane that seems really high for the stock fuel system. While tuning my Precision we hit lean conditions just over 27PSI so we dialed it back to 24/24.5 now its 25.5+ on meth, but I regularly hit 27. What are your AFRs at that PSI?
