N55 Intake Idea
Anyone have thoughts on doing this for an N55? Im so tempted to try it...so..so.. tempted. But as far as I know the N55 much more sensitive to all changes on the cold side compared to the N54 correct? Input please. Thanks!
if that works for a F10 550i i will do it with you lol
1. Why would the N55 be more sensitive to changes on the cold side? And what do you even mean by that?
2. These types of intakes are only beneficial if your turbo is causing negative pressure in the pre-turbo intake while boosting. To see if this will have an effect, you need to do some manometer testing on the intake along several points. Otherwise, all you're doing is marginally cooling down the intake air and letting more sound out.
This setup is actually pretty stupid. There is no need to add a filter on the end of the secondary intake hose. In fact, you're defeating the purpose of this hose. The hose should ideally face forward in the front of the valence with a scoop to collect air while driving. The idea is to pressurize the airbox with as much air as possible to prevent negative pressure. Adding a filter here is redundant and counter to the original purpose.
Here is a better setup. This was from my Volvo days. Not my pics, but I had a similar setup. Another engineer and I did extensive testing to see gains. Even running a tune with 21 psi of boost, it was less than you would think.
^ I believe the issue is MAP vs MAF.
Also, I know what you mean in terms of the filter bring redundant but I guess it was for the purpose of filtration. You're increasing air intake but retaining the same amount of filtration, so I supposed the guy who made it figured why not stick a filter on it as well. In California, we've been hitting high 90's-100's consistently. Considering it costs less than $30 in materials(if not including the cone filter), I wouldn't mind doing it.
so the question is....is there anyone in vegas that could do this? And does it have a sound difference
