Got a boost gauge? Post your peak boost numbers!

nordique14 · 04-14-2010, 05:19 PM

Quite a few people are now running with a P3 boost gauge or some other kind of boost gauge. I would be interested in seeing some peak boost numbers. It would be a good way to compare stock vs the various tunes (JB3, SSTT, Dinan, etc).

This weekend I hit 10.5PSI. I have the the BMW Performance Power Kit. Temp in the high-50s and I am at sea level.

It can get pretty hot here in the summer. I will be watching the peak numbers to see how much the weather affects the boost.

I know for sure I've hit the 14.1-14.3psi range on multiple occasions. Might have hit the 15's once when I was really going full out on a nice cool day.

10.5 is not too shabby though.

themyst · 04-14-2010, 11:17 PM

Heh I've sustained 17.5 at most.

adrean8j · 04-14-2010, 11:51 PM

Just came in the house...hit 18.1psi on Stage 3+ in 3rd/4th gear starting at 3500rpm(around 56mph) to 5700rpm.....I think we should take pics to prove it!

nordique14 · 04-16-2010, 02:03 PM

Wow. 17-18PSI is high boost. Isn't that like double the stock boost?

Anybody have any stock boost numbers to post?

On a cold day, I've hit about 9.6 psi of peak boost during a shift spike. I have a 6mt. During my stock dyno run in 4th gear, I saw 7.6 psi of sustained boost at peak.

DBFIU · 04-16-2010, 03:31 PM

14 peak on map 5 JB3 2.0, stock otherwise.

Dackelone · 04-16-2010, 04:50 PM

How come on this N54 Tune Caparison chart, its says the JB3 runs up to 20 psi. ???

Jb+ @ Default Setting - 12.6

infinitekidM2C · 04-16-2010, 08:03 PM

Full throttle i usually hit 14.5 according to my boost gauge...my dyno says i hit 15.5 though

Mindgame · 04-17-2010, 09:01 AM

Jb3 1.4 Map 5

16.2 Psi

acivick · 04-18-2010, 08:55 PM

Got up to 15.5 today. Wasn't sure I'd be able to get a pic, so I took a short video instead...

and 1 · 04-18-2010, 08:57 PM

jb3 2.0, map 7, no engine mods...17.3 peak earlier this week. i usually only see a peak of around 16 tho

Irishace · 04-19-2010, 12:05 AM

16.1 off of a quick WOT burst on map 7. I am sure I will press 18 on a sustained WOT run.

I was actually a bit surprised to hit 18psi...

It's all in the mods. 2.0 with an 18ohm board intercooler meth straightpipes and intake I'm sure you can hit 20psi. Of course one of the biggest issues is getting those annoying little waste gates to hold the boost.

onefastman · 04-19-2010, 08:46 AM

I wounder what boost one would be pushing with 18ohm, map10, strait pipes, intake, and methanol?

jtsherri · 04-19-2010, 08:54 AM

17.8 - JB3 2.0 (Map 7), Injen Intake, cp-e non-catted downpipes & cp-e exhaust.

ridin135 · 04-19-2010, 09:07 AM

stage 3+ 15.4 but I have hit 26.5lbs of boost twice though that was due to faulty firmware that I uploaded.

nordique14 · 06-02-2010, 06:12 PM

Hit 12PSI a couple of times with the PPK this weekend at Laguna Seca. Temps were cool so that helped out.

Smac355 · 06-03-2010, 08:40 AM

so how accurate is this P3 gauge? I hit like 16 w/ Dinan ST II... didnt think it was pushing that much boost?

That was probably a shift spike.
