Max PSI

Aaron_N55 · 08-18-2014, 07:17 PM

Hey everyone I was just wondering what is the max PSI you recorded on your N55 and your mods. As of right now I'm making 16.7 PSI on just Cobb AP3 Stg 1 Aggressive with BMS Intake, ETS Charge Pipe and 93 Octane.

AJF80 · 08-18-2014, 08:03 PM

Im running the JB4, BMS intake, VRSF Downpipe, & 93 Octane and pushing around 14.5-15 although I think I should be making more... What are you using to measure your boost? do you have a gauge or are you reading it off of the Cobb?

I'm reading it off the COBB. The real reason why I'm asking this is because from searching throughout this forum my reading seems abnormally high.

I've hit 17-18psi in older weather jb4 map 5. Car actually started breaking up in 4th gear from load. Catless, intercooler, filter, tune.

JB4 or COBB?

Nugget · 08-18-2014, 08:28 PM

21.6psi as that's the most the stock sensor can read.
That was FBO, Vargas stage 2 and e50. Map has since been adjusted.

I cannot imagine how hard that must pull. Is that your E82 N55 DBB VTT Stg. 2 on YouTube?

Johnny Boost · 08-18-2014, 08:50 PM

Aaron do you have any pictures of your car? I always wanted to see what those M-sport wheels look like painted

Aaron_N55 · 08-18-2014, 08:59 PM

I first had matte black then stuck with midnight blue. The rolling shot was after KW V3s. (Yes it is Plasti-Dip)

M.a.r.k.u.s · 08-18-2014, 09:12 PM

18.6 according to my last log with 5.5 gallons of e85 and fbo.

Knobi · 08-18-2014, 09:30 PM

18.2 with 40% E85 and FBO on sucky Florida weather (100+ degrees). Waiting for Boost Weather

MegaModder · 08-18-2014, 09:47 PM

I see 16.5 psi pretty regularly but only for a quick spike. 2011 335, Cobb AP3 aggresive map and a K&N. That's using the AP3 datalogging. Manifold temps go from 125 down to 110. My setup sounds similar. I've seen peaks at 19.5 psi but that seems like a bogus reading.

That actually looks a lot better than expected. Very nice

Map is still getting worked on, but even the map for normal petrol pulls pretty hard.

Car looks great btw, blue wheels work suprisingly well.

335iFFM · 08-19-2014, 02:36 AM

21.4psi in 102RON with Stg1 PureTurbo. Much colder in Germany than in the US.

Car is a E93 DCT. Map is still in development but I'm currently out of country. We will proceed in a few weeks

100+ Degrees and I'm complaining about 85 Degrees

That is a high spike! But it seems we're running about the same.

Yep! That's the car I was talking about. It sounds amazing!

I'm surprised the blue worked out well too. I thought it would look ricey but that amount of compliments I received made me stick with it.

21.4 seems pretty good with just a stg 1. I'm stuck between a turbo upgrade or just saving up for an F82.

Subaru335i · 08-19-2014, 11:27 AM

OP do a fucking log and see what boost you are actually making, I will give you a hint: you are not actually making 16.7 psi.
This thread has been made like 2000000 times on this forum, why do people not learn how their car works before they mod it?
One more hint, google "throttle closure boost spike 335i" and

weehe126 · 08-19-2014, 12:17 PM

20 to 12 psi E45, JB4 Map 6, 7" FMIC and CP. Asking for a specific psi value is pretty useless. Unless you are stage 2 or higher you will have boost taper and you will not be holding that 16psi at redline unless you are at least FBO stage 1.
