Re: Re: What is MEVI ??
You know what? It's not on page 2. Little typo needs to be corrected.
Anyhow, to find the info, pull up the link below, at the top of the thread, on the right hand side, click "show Printable version." Once your browser has finished downloading the entire 40 pages into one long thread, use Edit->Find(On this page) and find for MEVI. The info will pop up. Do a find again and even more info shows up.

I think it means Middle Eastern Variable Intake. What it does, is at lower RPM, your intake will function with less airflow, and at higher RPM, it will open up a little door letting more air flow into the manifold. Correct me if Im wrong, but I think that's how it works.

If you people could search around for 5 seconds or read all the FAQS it would be much easier then waisting bandwith with usless threads.
What is the MEVI ?
The MEVI, Middle East Variable Intake (Don't know the official name) is a 4th Gen thing...
The Infiniti I30 is sold in the Middle East (Bahrian, Saudi etc) under the name Maxima, and it has a specially-designed intake.
It's not a true Dual-Plane intake (like the Taurus SHO, or the 3.8 SPI from the later model Windstar/Mustang) which has two distinct air paths from the air filter to each cylinder (one long, for low revs - one short for high revs). Instead, it's a Dual-Plenum design that has a second plenum directly above the lower intake, providing a shorter path for the Dynamic Supercharging effect (described below). The second plenum is 'activated' by opening a set of butterfly valves. These valves are opened by a vacuum actuator at the appropriate engine speed.
Dynamic Supercharging is the concept that when the intake valve closes it causes a pressure wave to travel from the outside of the intake valve back towards the air filter. When the pressure wave reaches the plenum (the common part of the intake track between the throttle body and the individual runners) it bounces back towards the intake valve. If the intake valve opens just as the pressure waves gets back, then more air is forced into the cylinders and it increases the volumetric efficiency. There is a specific engine speed at which this Dynamic Supercharging effect happens, and the length of the runners changes this engine speed, because of the time it takes the wave to travel.
Intake spacers change this effect to a lower engine speed (because the wave takes longer) giving the engine more bottom-end grunt (marginally, and at the cost of mid-range grunt)
The dual-plenum design gives the engine TWO speeds at which dynamic supercharging happens - at high speed the upper plenum valves open and the shorter path to the upper plenum gives the dynamic superchargin effect at higher engine speeds, increasing breathing and prolonging the powerband.
That's it, in a nutshell.

it's not about knowing wether it exists or not, its about finding out where to get one, there were a lot of posts that explained what it was but none of them said anything about where to find one.
thanks superblack for the link..
