what if i get someone to custom-make the stock airbox if its possible? so instead of using the tiny heat shield, the custom airbox will seal it..get my point? sorry for my bad english, but i'll try to have this done when i go back to indonesia..autoshops there do all kind of stuffs at a cheap price |

That would work, but try using a material the doesn't conduct heat as well as the plastic used in the stock airbox to get better gains. Also check out the stock design and see if you could make it better for more efficient airflow. If you ever get one designed and made at a reasonable price, I'm sure that many people would be more than happy to buy them.

hopefully i'll be able to go back to indonesia this summer if not i'll ask around for help in columbus too, my friends know more about engine parts than i do..perhaps i can get some local help but cant anyone here help us out though? dtmkarbon should be able to do this, he can make an oem cf hood so a custom box should be easy if he has a sample. i'm wondering if fujita's and britalman's size is similar. if its of the same size, someone should make this custom airbox! and give me a commission too for my idea in the meantime i'll ask around..time for me to go offline, 2midterms tomorrow and 1 on wednesday peace out everyone |

Very good point! [/QUOTE] Hey no love loss bro. I am good people and I don't want anyone to think I am some kind of scammer. I will address the TQ #'s with the dyno shop and maybe they can give me some free runs with the hood down. |

anyway, no, i'm not asking you to do anything more. i wasn't aware that you paid for the dyno run. since creative is trying to sell this new product, with your help, i figured creative paid for it. put what's posted is posted. it's a public forum, where anybody that has interest in e90's can come together and discuss things about our cars and other things. i'm not trying to knock the product and telling others not to buy it, they can form their own opinions. i'm just stating mine going by what was posted in this thread.

Wow, that took a while to catch up. Interesting . . . I haven't formed an opnion quite yet. While gains are possible and probable, I do see justification in the questioning of the numbers. Part of me really wants to get one and another part is still a skeptic. We'll see I guess.

Well, actually you should dyno a car with a hood up, it becomes more accurate then with the hood closed. Why is that? When your car is sitting on the dyno instead of blasting down the highway, you're missing about 60mph of cold wind blowing through your engine. No matter how good of a fan you got in your shop, it is not going to be able to replicate that one factor (not to mention most shop got a small shop fan sitting in front of the car "simulating" real world condiion). Counting out other factors, this one variable in air flow already plays a major factor. The car is running a lot hotter than actual road condition and probably sucking in less air, because hotter air equals less actual air molecules to mix with the fuel, thus ECU will compensate by adjusting timing and such, which cuts back power. So you see, that dyno only reflects how the car will react under that type of simulated condition, which is a far cry from what your car will be running at in the real world. So what I'm suggesting to everyone is not that the intake is useless and that hp gain is fake, but simply that you shouldn't make your decision on purchasing the intake based on that dyno result.
Also, a sealed cold airbox would definitely be better than just that thing sitting in the engine bay. And dyno aren't that expensive... about $75-$100 for about an hour.

You are correct. There are no such things as 60mph fans, those are only present at wind tunnels. I had my 325I 6MT dyno'd last year. And let me tell you first hand.. this dyno sheet is pure bullshit. Something tells me the car was never dyno'd at all. Why? Because when Fujita was dyno'g azian beemers 330I automatic.. they couldnt get the car to stay in gear, it constantly wanted to downshift once you gave it. Here is my dyno sheet.. its actually proper. Here are more pics (as posted before) from the dyno day: http://www.kwlt.net/dyno/ Max power is at 6200ish RPM, and its 201WHP. Wheels make nominal difference on a dyno. My dyno was done at Spitfire Performance in Missisauga, ON They do nothing but build race cars and street/race cars, producing some major power. Dyno is regularly checked and tested, as it needs to be 100% accurate when dyno tuning a 1000+HP race car.

Fisrt off I know the TQ and peak RPM numbers off but that does not make the Dyno result bullshit. I could post pics of my car rolling on the dyno, would that make you happy? We were having the same problem with the auto tranny as Azian in forth gear the car would kick down to second right before redline. This is partly the reason we got peak HP a 5000 because we had to do the runs in 3rd gear, this may have contributed to the TQ numbers as well. The HP numbers are consitant with your 325 and you don't have the loss from the 20" wheels and auto tranny. I any of you would like to call the dyno shop to confirm this please feel free, thier info in in the GP thread. |
