Is there anyway to check the boost on the e55

E55Pilot

Yeah get a boost gauge

Marcus Frost

Depending on when you want to read boost - for me it was easiest to drill and tap a fitting. There isn't any easily accessible boost source from the factory on these cars.

Maybe while driving. I just wanted to see if the car is boosting as it should. Where did you drill for the fitting

alphanumeric

thats an idiot answer , but to answer the op... it has to be after the intercooler.. so around the intake manifold area

anyone do a boost gauge? i have been toying with the idea, not sure where to tap for a good source and not sure where to place the gauge itself

Vadim @ FD

You can read boost through OBDII scanner or tap a line into one of the intake surge tanks. They are the ones with AMG log on top.

You have a boost gauge?!?! What a ricer.

JK man, why don't you organize a Chicago meet already? It has been too long!

2 questions regarding this.

1. If I tap a source after the IC before the TB, what boost levels should I be seeing on a stock 55? I know they are rated to run .8bar (11.5 psi), but what type of loss is seen in the intercooler?

2. If I wanted just a temporary source, is there any available temp sources? MAP, FPR, etc...that could be used for a single pull just to monitor the levels? Obviously, neither of those sources are good sources, but I hate having to tap into something permanently simply to monitor the boost for one pull basically. Same for why I would not install a gauge, I will simply tape this to the window, or drag a vacuum line into the cabin temporarily.

Thanks,
Scott

Very funny. No, I don't have a boost gauge, it's so I can measure boost on the dyno. Have you seen how many times my before/after boost chart has been used on the forums lately?

I agree with it being too long since we met, maybe we should try setting something up.

Thanks for the info
In order to read it from the obdII port do I need a generic obdII scanner or do I have to use star.

E55Pilot

No it's not.

Marcus, do you have any pics of your boost gauge setup... thanks

Marcus Frost

I don't. CPT did it for me.

aleksandar1099

I mean where did you mount the gauge inside the car?

Thanks

E55Pilot

Mine is in the glovebox

Vadim @ FD

Either one, as long generic supports CAN bus.

Thank you once again

Alexandarr,

I don't have a gauge in my car. We put it on for tuning/dyno purposes - so when I strap onto the dyno we have an easily accessible boost source. I could put a gauge on it but boost is fairly static with parasitic superchargers - it's not like a turbo car...

sorry if I came off rude, it just seemed like a sarcastic reply "a boost gauge" duhhhh lol

aleksandar1099

I see.... I was thinking about putting one in the car, I thought it would look kind of cool, but not the ricey kind of gauges....

alphanumeric

I put one in my 2000 c230 Kompressor.. it reads a whopping 5.5lbs of boost hehe, tho I think my boost gauge looks cool in the c230, I don't think its appropriate for the E55, its to elegant.

aleksandar1099

Looks good in the c230

I was thinking of a smaller one in the ash tray....

alphanumeric

what would be nice is boost, oil pressure maybe oil temp and a\f ratio if you are tuning, tripple gauge in the center console like the w201 190e 16 2.3 16valve .

or a single digital gauge that reads all.. i think that would be best for the modern sophisticated e55 kompressor.

right here works great.,, find a place where it will not interfear with TB or any thing then remove either side the manifold drill , tap it what i did was tighten the fitting into the maniflod ,,then count the thds inside sticking through,, remove the fitting, grind off those thds so i had a smooth surface inside, . good luck,, have fun . I made my own pillow pod,, found one that almost fit heated it with heat gun and remolded it to fit,. jim
