wth why dont they even attempt to put a box around that?
shoot my cousens 1991 has a better intake then that(homedepot, office depot).
those numbers are so low!!!! why??

[AznBeemer23]

On some automatic transmissions, the computer will automatically change the gear on the dyno. The BMW 330 was one such vehicle. Fujita tried to get the car to hold a 3rd gear run but the car continued to upshift and or downshift automatically. The piece on my car now was a prototype piece made in 1 day just for the SEMA Show. My car is going back to Fujita to develop a production piece which will be quite different. A new air mass fitting has been produced which was new to the 06 E90 chasis. I was told the intake final would come in either chrome or wrinkled black finish.

I know everyone has his/her's opinion about stuff, but give Fujita a chance before making your decisions on the product. They haveover 12 years experience in the intake market.

[Guess]

I spoke to Ryan @ Fujita, and yes, aznbeemer is very much correct. The dyno didnt work as the car attempted to shift for itself.

I was also told the same, that this is just a prototype, not even a production model or anything. I would expect a much better design from fujita, as they are a very high profile company.

if the product's not ready for production maybe we shouldn't see pictures of it yet, it makes the company look bad

Ah, a voice of reason. Good point Ward.

[AznBeemer23]

It was made for SEMA in one day........
it was just a proto type if you read what I posted.


I bet your 325 is STILL stock WARD.

I also bet it will STAY stock AZN

[a burrito]

and i bet my stock 330 will beat aznbeemer's 330...whats the problem with stock cars?

[LOLrance]

i bet his car will stop way faster then all of us with his big brake kit

Not neccessarily. A big brake kit may give you a better brake feel and it will give you a more constant brake performance when you accelerate and brake hard all the time (such as on the track). But it will not normally shorten the braking distance in regular driving conditions. The stock brakes will usually not fade even in the most spirited street driving and allways have more than sufficient braking power to lock up all wheels from all speeds.

As long as the brakes do not fade (loose braking power due to overheating) and have sufficient power to lock up any wheel, the braking distance is influenced by other parameters:

- Either the pedal feel and therefore the ability to regulate the braking very closely to the point of lock-up (but still rotating) where maximum deceleration occurs OR in case of a full panic ABS stop, the quality of the ABS regulating mechanism (meaning how well does the ABS keep the brake pressure as close to the lock-up pressure as possible without actually locking up)
- The point of gravity of the vehicle (height and longitudinal point)
- The tires and the road surface
- The flex in the tires
- The suspension (in multiple ways: how much weight shifting under braking does it allow, how well does it keep the tires planted to the road, how does the suspension hold the tires relative to the road (camber etc.))

Reasons for getting a big brake kit would be:
- Very big (and heavy) wheels: If you go wild on your wheel and tire combo (say 20inches with 285ers on an E90) you may be increasing the rotational mass of your wheels to a point where the stock brakes might not have the power to actually decelerate those wheels to the point of lock-up from higher speeds
- Track driving: The one thing the stock brakes don´t take too well is track abuse. They´re simply not built for that. The pads are relatively soft so they will grip immediately even on a cold brake and not be too noisy (the soft pads are also the reason for the excessive brake dust on BMWs). So on track driving where you simply have way more full braking maneuvres per mile than you´d ever manage on the road, the stock brakes simply might overheat and loose braking power
- Optics: Big brake kits with fancy rotors, steel brake lines and colourfull calipers simply look Esp. If you have really big and "open" wheels
- High load driving conditions: Not really a typical E90 scenario, but if you´re in the habit of regularly loading your car up to the maximum loading capacity, hitch up a trailer with a load that uses your maximum towing capacity (say with a boat on it) and then tend to drive up and down the Rockies with that combo, then the same as with track driving may apply. The stock brakes may not cope with that load thermally.

Under normal driving conditions though, a big brake kit may actually be detremental to your braking performance.
Best case: You get the same braking distance as with stock (both systems simply have more braking power than the rest of the setup can use). Only if the stock system is underdeveloped (as it is on some cars, but not on the E90, at least not the 330), a big brake kit can improve the stopping distance
Worst case: You get a big brake kit that is tuned for certain (racing or tracking) conditions, has very hard pads and needs a certain operating temperature to function well. Then the stopping distance in an emergency stop (which usually means cold brakes) may actually be longer than with the stock brakes.

Now wth did trigger this incredibly long post? It´s not as if anybody had asked for it. Sometimes, I just can´t help myself.

Short answer: If his car DOES stop faster than ours, it´s not neccessarily because of the big brake kit. More likely the lowered suspension and more rubber to the street.

yup, your right. just read about that bbk theory over on e46fanatics.com. soooo my cars still faster right ?

Your 330 is the fastest car on the planet. And your the fastest driver of all. Second only to me of course

[lux.sh]

lol @ fastest car on the planet.

Yes, "BBK = shorter distance" is not true, or not always true.
Under constant*(key word) and consistant hard braking, car equipped with BBK WILL decrease the braking distance compare to stock.
BBK however, requires higher temperature to operate at optimal range and show its true potential.
In normal daily driving condition, BBK kits, really, aren't needed. In this particular condition, BBK won't really stop better than stock brakes at all, and even sometimes, added weight from BBK will DECREASE the performance of your vehicle, even braking.
Its matter of how fast it will start fading.

[QUOTE=lux.sh]Saw this few days ago.

At least it gained some power thats good news. QUOTE]

Couldn't that also be attributed to different days too? When I was pretty big into my mustang, I dynoed it quite a bit. One week I had 490hp, 505hp the next week with the same setup with differences in the torque curve as well.

Yep. thats why manufacturer's dyno "proof" aren't very trusthworthy. They could've done the base line dyno on a hot humid day, and ran intake dyno in colder condition. who knows.
Reason why I still haven't bought fujita intake yet, I want to see someone else's dyno with accurate numbers. Especially under same conditions. And using which dyno also matters, different dynos post differnet numbers.

I think he means the variance is between individual runs on the same dyno.

[clubspec330i]

yeah...

My '03 330 Step dyno 197HP at SP Engineering in City of Industry.

It seemed like Fujita design is VERY SIMILAR to that of Injen intake.

[shragon]

that's a terrible intake design. i'd stick to stock before putting that thing on.

[e90kid]

Were can I get one of these intakes? Would it void the warrantee?

[lux.sh]

ebay. an intake shouldn't void warranty in mechanical aspect, however, dealers won't care. they can do anything(including voiding your whole engine/tranny warranty).

[ACZakka325i]

so are we saying that this intake does not actually give us a gain and that these dyno test results are unsubstantiated?
