Eventuri VAI Carbon Intake Kit for the Z4M details

Hi guys, Chris ( crfine88 ) and I have been sharing some ideas on creating more room for the WP under the elbow and the routing of the coolant line equalization tube.

For the WP Chris and I collaborated on a way to create more space by lowering the mounting bracket as well as canting the mount angle.

The mounting bracket is mounted with two 10mm screws.
The WP itself is on three rubber grommets which simply side up to remove.

Once off two extension tabs were added to the bracket, which lower the mounting position.
The tabs where given a slight angle bend which does two things;
it cants the top of WP towards the fender and gives clearance for the screw heads. (I used counter sunk heads)
If you are making tabs, use 25mm center to center on the holes.

These pics are from the trial fit.
They will be cleaned up and painted black to match the OE bracket.

Next was the coolant line.
Chris and I both felt that running the line in the OE location really detracted from the beauty of the Eventuri intake.
My first inclination was to make a new line and re-route it.
Chris came up with the idea of just rerouting the existing line w/o need to disconnect it.

One concern that we discussed was whether it was OK to have a droop loop in the middle.
This line is not used for flow; the function is for pressure equalization, a breather tube so that coolant flows back and forth between rad and expansion tank freely.

We speculated that any pressure build up should blow by any condensate or coolant that may find its way to the bottom of the loop.
This is further corroborated by the fact that blower kit installs also re-route the line in a similar way.
We will continue to monitor this mod.

At the tank end the two nuts were removed and there was enough play in the tank to lift it up and lower the tube below the tank. ...dont mind the dirt :rolleyes:

the rest of the Eventuri install notes apply from this point onwards :)
 
I'll be interested in hearing the results, from different sources to the ones already available. Personally from what I've heard on existing videos I'm not a fan of the GruppeM sound, it sounds too artificial and imho purely from the videos it doesn't do the engine justice, and I honestly prefer the natural engine note to that. Interested to see how this pans out :thumbsup:
 
Nice to see new stuff coming out. Looks like a quality piece of kit. It should open up that intake sound nicely. 8)

It is a difficult one, the noise from the M, and appears to be a very personal thing. For one, I like the 'rasp', others hate it, but it's one reason I won't change the stock exhaust as to me most aftermarkets lose the rasp and just add a louder drone. Modding the air intake seems the only 'halfway house' option, it'll be interesting to hear what the Eventuri sounds like in a proper video.

That's exactly how I feel Andy. Mine is being fitted a week today so I'll try and get some videos up as soon as poss although those going to the open day may just beat me to it if they buy one and have it fitted on the day.

Yes I agree - most intakes give negligible gains - until now for the reasons above:)

Sound is an important benefit although we consider that to be a bonus over the improvement in power and response which the Eventuri delivers.

Open day has been confirmed : Saturday 28th March. 9am to 12.30pm

Hope to see you all there!!

Damn! Just seen this and I'm only up the road, but can't make it. Would of been good hear what this new intake sounds like.
 
Good man,

Why wait, get it bolted on....lol...

Are you doing before and after power runs ? Any mapping ?

Because I'm useless at fitting stuff (plus I don't have any tools or spanners)! :rofl:

I had a dyno run a couple of years ago but nothing since. So it won't be very scientific but I'll probably do another one after it's on. At this stage no plans to remap so it will be 100% stock with the exception of the intake. I'm doing it more for some nice induction noise really. Any power gain would be a bonus.
