Turbos that runs more efficiently with better duty cycle will not have to work so hard to produce boost as a turbo lacking it using more duty cycle You will probably get the same gains as a DCI, but power on this setup will come much more earlier though in the RPM band I haven't completed my review yet, but I am very satisfied with how it's performing and I am no fan of DCI setups. So if your looking for price vs HP, then take it off your list as said before. If your looking for early power gains, and efficiency then this intake is well worth it.

Looking at the dino numbers on ECS website for this intake shows a loss of HP, with a almost stock set-up - not that convincing.
On the price comparison - I was looking to see if you think this is a better option than the AFE one you were previously using |

http://www.e90post.com/forums/showpo...5&postcount=89 You can see clearly my clutch was slipping from since the first dyno with the stock intake and when I got the ECS intake installed it got worse, not to mention the significanly higher temps and higher IAT I had to dismiss these tests results as not valid due to my clutch slipping. Now that I am FBO+ with a stronger clutch, I have to start over. I cant really say if its better than the aFe atm until after I complete the tests, then I can make the comparison |

Good posts, BuraQ.
I never really knew that you could use inlets with an airbox; I always assumed that they would entail a sealed filter. What is the benefit of running the inlets to the airbox? Wider, shorter, and higher-quality tubing? |

You want colder air pre turbos in order to reduce duty-cycle, and run the turbos at a better efficiency for more boost. |

Are these the ones you're referring to? Seems like a lot for some silicone tubing, no? http://www.topgearsolutions.com/vtt-...s-bmw-n54.html |

The good thing though its easier to install on the Z4 . The only difficult part other than having all the space in the world the radiator on the Z4 drops down to install the front inlet and you cant pull up the Rad like on the other N54 cars from what was understood Other than that, the good part about those silicone inlets they are 2" in diameter and you can maintain a CAI setup. The TFT inlets you can't and your gonna have higher IATs unless supplemented by meth To be clear I don't like the VTT owner, and he doesn't like us. Credit goes where it deserves though for the product, as there was nothing else better to compromise with |

I did notice that RB was working on a set that were 1.75" at the turbo, which made me think they might be a better fit. And the price point is more reasonable. But it's not worth it if you have to run DCIs. That was one of my biggest hesitations about inlets before I saw your setup. BTW, I think my buddy might have stopped by your shop the other day: VO 1M from New Jersey. |

Here are some Virtual Dyno results. I don't know how accurate the whp/wtq numbers are but they are very close when I last got on a chases dyno when the car was stock + tuned . However, I am more focused on the illustration of the power curve

Will leave this right here as my last iteration. Will need a dynojet chasis dyno to confirm numbers but am going to wait till weather gets cooler here in Florida
Here is the street log of the VT dyno below http://datazap.me/u/buraq/v22?log=0&...11&zoom=34-200 |

I am new to the forum, would you be kind enough to confirm that the AFE seal intake stage 2 Part # 54-82002 or 51-82002 will fit under the hood. I have 2011 sDriveI35 and was getting ready to buy when afe tech rep told me it won't fit under the hood due clearance. Thanks in advance

The oiled has better air flow, the dry filter is if your live in a very sandy dusty environment I am the one that verified this information for aFe Power when they had no idea the N54 was being carried in the 35/s models. aFe tech is assuming the wrong. Also you want to check out the Carbon Fiber enclosed intake if money is not an issue https://www.ecstuning.com/BMW-Z4-sDr...ake/ES2713282/ More expensive yes, but the carbon fiber repels heat better and won't get heat soaked like the aFe intake. I have them both and I know how they work |

SAE & STD Dyno
483-491 whp / 577-587 wtq SAE/STD corrected in 93°f temps. Waiting for colder weather to crank things up more to hit 500+ whp / 600+ wtq which will make it the most powerful N54 on stock turbos

Any updates on the intakes, which one you like better, etc..? Still looking at the aFe (want to see me your old one?)
About to put the RB inlets on and may as well replace the airbox at the same time... |

I favor the ECS CF intake You will have no problem using the RB Turbos. Here is the VTT 2.0" inlets with the CF intake system |
