Anyone have numbers about which length intake is best for an EK9? Everyone always talks about cold air, but the right length can make more of a difference.
thats the resonator box,dump it.
I don't have the resonator box. Just asking why the cold feed pipe is angled upwards at the open end. I think the mugen intake has this feature too?
well if you cant get 1 part correct, atleast get the other correct.
Length of pipes just shifts the power band curve while a Cold air setup garantees consistancy in making power.
Too bad you have to be cynical about it...let's try to keep it friendly, you agree? Only shifts? It can also make it wider. It took more than 0,5s off my 0-62mph time on my previous car. I haven't said that cold air doesn't make a difference, I've never measured or seen numbers that made more of a difference than the right intake length. Check this out: Pipe Dreams. The gain you can get can be much more than you lose in another rpm area.
And if you don't believe me...well too bad but I've seen, felt and measured it.
Why not measure and see if you can get BOTH? The right intake length combined with a velocity stack and CAI? You can take the piping, take the length that you want (eg, in the example of the website I gave I'd take 65cm), put a velocity stack on it, put it in an airbox and then a hose running to your front bumper for cold air That's what I want to try and I'll probably make a DIY airbox. Let's see how much I can gain for as little money as possible
(maybe I'll first try to save money for an EK9 though )
By the way, the results I measured with my Daihatsu were on the road with a G-Tech Pro, measured in several runs. You're right about that it maybe has a bad stock design, but as far as I can tell from experience, unless your car is a VERY expensive one, there is always room for improvement!
