With the additional flow path lid, similar to Dinan, they didn't gain over DCI's but was it comparable? I don't think you can improve over the flow of DCI's, but if it can be equaled with something that is aesthetically better, there may be buyers. Did they have an idea on target price?

Search for "BMS air intake concept, a spectacular failure" on their forum, its from Jan 2008. According to them they doubled the volume of the lid.

$500 for an airbox? Thats insane! I was seriously thinking about doing this MOD but I think I will go the DCI route unless I can resource a used airbox cheap.

I have no interest in purchasing a kit with something so simple, but I would like to request a DIY from Mr. 5. (mostly for the parts list)
Thanks.

if the inlet size is the issue then we could cut a hole in the lid (or someone could fab a new one) and add a 2nd tube and route it to behind the headlight - no filter needed b/c it's feeding the panel filter. i personally like Mr. 5's better with a seperate filter & tube feeding beyond the panel filter, and i think it would look cleaner.

has anyone tested vacuum in the box? i've seen this done on ram air systems to make sure there's enough air available. sorry if this has been talked about before and i missed it. i'm wondering how much additional volume may be needed for a tuned engine...

[i2iSTUDIOS]

so anyone up for the job?

[midlife]

Looks aside - are you guys saying (what I have thought all along) that the UR cai concept having the air filter drawining in cold air from below the headlight - is the best intake ?

Because a new plastic lid with piping output would cost about $50.000 to make the molds for it...I would say it is worth it, but most vendors think it doesn't.

as we could see. the Mr. 5 solution is as good as DCI's and as the new Dinan intake.

Is there a vendor who is interested to develop such an optimized product ? Unless there is nothing to argue I'd prefer the filter(s) behind the driver side headlight and compatibility with various charge-pipes ( DV's and BOV's ).

IMO such an intake would be easy to maintain and to be removed ( in case a cover would be content of the kit to close the hole in the stock airbox ). Keep the space behind the fender for the BMW performance kit.

If you don't have the Power Kit, you can buy a Stett intake and separate the upper part of it (its connected with a silicone coupler and clamps) and connect a silicon elbow to enter the airbox. It would be very easy and I would do it if I wouldn't have the Power Kit which makes the Stett unusable.

For cars with the Power Kit, something flexible instead of hard piping would be best.

Here is a picture of how can the Stett + stock provide such an intake

[Kelvin1000]

Great idea.

Stett can do it and just change the one part after the coupler for those who don't mind altering their stock box...

[cstavaru]

I just read the BMW 335is will be announced these days at NAIAS. If it has the upgraded air intake found on the Z4 sDrive 35is (and it must have it) I hope we can just buy a 335is intake and fit into our regular 335i cars. And maybe it also has an upgraded intercooler we can fit in our cars

You guys still realize this showed a loss of power over the DCI. If you want a CAI, just buy the STETT.

Did you see Mr5 piping? could be much smoother then that --> better flow--> same power. (of course it has to be prooven first)

It was proven by Mr.5 that his intake is slower than DCI. I am telling you guys that the stock box in any form will not flow sufficiently for higher boost levels. You just need to come to grips with this reality.

Not everybody likes DCI's, not everybody likes WAES. Even at the cost of power. It's as simple as that. I'm not looking for maximum possible power, I'm looking for a well balanced tune ( in this case, reducing the overall boost parasitic loss ), keeping the car as close to stock as possible.

Mr.5 intake did 60-100mph at 4.39s. That is quicker than DCI (4.71s).
However, DCI was quicker at higher speeds. All in all, there was just a couple of runs, so you cannot make any definitive statistical analysis out of it.

Do you have any data about the amount of flow of the stock box? I'd like to calculate if it flows enough or not for "the higher boost levels".

Edit: DCI is an excellent choice though when you have upgraded FMIC and meth to keep the IATs low.

I don't think anyone here is talking about the stock box. Its about the stock airflow PLUS a stett-intake airflow. It will sure beat the Stett (for obvious reasons) and I'm sure it can beat the DCI in a summer...the test was made in the winter.

e.n335, I respect what you have to say and always have, however what you are talking about it safety too. You are accepting inadequate flow from the intake to support the needs of your turbos. What you are accepting is increased turbo rpm and increased wear on your turbos to maintain the higher boost levels. Your wastegate duty cycle will go up to prove this. It is time to debunk the theory that you can run above 13 psi on the stock intake without detrimental effects.

No it will not beat the STETT. I have one of the largest deltas (increases in power on this forum) and I am running the STETT intake. I have over 170 rwhp gain from my car with zero boost loss at high rpms. My wastegate DCs are well within safety specs. On the stock intake you are out of safety specs. If you don't believe me that log your boost and see what happens at high rpms. There is a reason people have to run special tunes to get fast times on the stock intake.

[marconi118]

with stock airbox there is low pressure (vacuum) building in the intake pipes going to the turbos. To obtain the same PSI at high rpm the turbos have to spool faster (the wastegates are closed longer)

I think the only proven test should be to measure this vacuum in the intake pipe.

Is someone with tune (JB3 procede or flas) willing once to hook up a boost gauge with negative scale to the inlet pipe (the rear one near the dashboard) where normally the oil breather is connected and measure this vacuum under full boost at 5Krpm????

Then we could compare with the DCI vacuum that should be nearly zero.
This is the only way to ,measure how restrictive the stock air box is (even with Mr5 or Dinan snorkel).

In my advice we have to find a complete new piping starting from the turbos inlet... but difficult in a tight engine bay.

[i2iSTUDIOS]

so is anyone working to make this or should I start making my own?

[Sniz]

make your own, I agree w/ Former Boosted on this. Get a true CAI with as large a filter as possible (UR or Stett) and move forward.

I was running I believe the 1st UR intake sold in the US and loved it from day 1. Only thing I would do is wrap it with heat wrap or thermal coat it and enlarge the filter they provide for you.
