325 E90 with Arma Supercharger

ZShift · 07-04-2011, 01:44 AM

hey guys,

I have been off this forum for a bit since i have been busy playing around with a 911T 6MT that was shipped to Beijing about half a year ago.

Recently, I have decided that my 325i 6mt (N52b25) daily driver is a bit of a bore especially with the ac on in summer days. Unfortunately research shows that not many SC kits for this engine. (Perhaps due to the lightweight magalum block?) There is only one manufacturer that is based on taiwan called Arma.

Having no better choice, I decided to go with it since I never had a chance to play with a sc'ed car. The kit was shipped here direct from Taiwan. Out of the package, Arma seems to have done their R&D quite well. The sc, intercooler, piping, etc.. were molded nicely and installed without issues into the car.

Upon starting the car, the sc sounds lovely. The beautiful whine makes the entire car come alive.

I took it for a test drive but was told that the car is in break in period and would not show significant results until after 500km. I was also told not to go past 4k rpm until after breakin. Also, I was told that my eisenmann race exhaust is not high flow enough for their system and recommends that I use their specially designed exhaust. Is there any sc experts that can help me with this logic? Initial response feels that the car is quite slower than my previous setup. The car seems to peak at 100km at around 4k rpm. I think that my car may be in limp mode as obd shows that there are lambda (afr) errors. Arma will send me an ecu bypass and hopefully we will be on track again. Will keep you guys updated. Also any techinical advice on the sc setup will be appreciated.

Sorry will get more pics posted as i am now in the office.

here is a link to a video clip of car

Whoa cool man. How much HP are you suppose to get out of that?

ZShift · 07-04-2011, 02:11 AM

Finally we have a review!

What kind of error you are having?

ZShift · 07-04-2011, 08:45 PM

for now, the obd diagnostics shows an air fuel ratio error. arma says they will send a chip to clear it up... the yellow engine light came on as well. not sure exactly what that means though for the error? anybody care to help out? fuel economy is riduculously low... 20 liters per 100km. hopefully all this will be fixed up.

Engine errors can be cleared and computer learning can be reprogrammed if you know what you are doing, too bad I am no longer in Asia or else it would be interesting to visit Beijing and see your setup. I could have helped with some of the diagnostics on the car.

But I'm sure ARMA will slowly fix it, it's giving you errors cause their piggy back tune is not 100% completely integrated and in sync with the MSV70 ecu.

SLAMMED335 · 07-04-2011, 09:09 PM

Nice kit + setup, good hp number's. Is that WHP? Or is it at the crank?

thanks dimsum... arma is working on the errors and you are right about the piggyback tune. i will need to be patient. they also claim my eisenmann race is not highflow and will ship their own custom made exhaust. my desutschland bmw will soon become made in taiwan. hopefully arma doesn't let me down

Are they shipping it to you for free?

If not, then it could be a marketing scheme. The supercharger and longevity of the engine will not be affected by a more restricted exhaust. The increase in performance is probably what their hinting at, in which case the eisenmann will be sufficient, I have no doubt.

Congrats on the system. Could you take a startup video from outside the car? I would like to hear the system on startup.

Hope you enjoy it

i paid a deposit... they also told me that after the full kit with exhaust installed, i can dyno it and they guarantee at least 30% increase or a full refund.. so i am anxious to get the exhaust and follow through with their instructions.. after all.. what are guinea pigs like me for?

wow, that's a big bump. They must have designed a dependent system around that entity.

If there giving a refund guarantee, then I guess they're confident in the system. More power for you

Anyways, when you get the chance, I really would like to see the startup video if you can. Thanks man

i updated my post with a youku link... take a look if you like

nice video... anxious to see dyno!

issabmw · 07-05-2011, 01:29 AM

Nice video!

I can see the fault with the A/F that you were talking about. The car is not pulling sufficiently. Hopefully you get that sorted.

tamster00 · 07-05-2011, 02:06 AM

this looks great!

AlpineSwift · 07-05-2011, 03:21 AM

GAWD DAMN!!!! THAT CAR SOUNDS FAWKING AMAZING! What exhaust is that!? The supercharger makes it even better.

c_jeong89 · 07-05-2011, 03:33 AM

yeah that vid was pretty sick.

CobraMarty · 07-05-2011, 05:18 AM

What is the piece near the differential? Is that a secondary fuel pump?

uweric5985 · 07-05-2011, 07:09 AM

Hi ******,

Have you consider supercharger from a company called YJK?

They are Rotrex base charger and also claim a similar gain in performance.
