MG MGF Technical - FAO Rob Bell, re air boxes
|Hi Rob, i was looking at your excellent site today and spotted the stuff about the Rover 820i air box, (though interestingly i can't find the page on your site now...), i wondered if you'd got anywhere with fitting this? You may remember i made a metal semi-enclosed housing for my K & N after being inspired by your 'chimney'. I was wondering how the 820 box could be mounted and what air tubing it would need (at both ends). As i said I already have a 57i with its connections if these could be recycled. |
I've never seen the ITG kit insitu but looking at the photos it looks like it comes with some kind of a mounting bracket, any idea where this mounts? Does the bracket then form one end of the filter housing? This MS supplied Viper kit (again from the photo) doesn't seem to have any sort of mounting for the filter housing, just sits on the intake like a 57i, does this tie in with what you know?
This all may be a bit passe now as it seems TF excitement has taken over..., and i see you WANT, WANT , WANT one...*grin*...only kidding. Anyway with someone with infinity time on their hands like me i'm looking for the next F project, the painted headlamps now being complete.... Any thoughts on the air box thing?
the page is not linked from the main page yet- and is, as you guessed, work in progress! LOL Direct link is http://www.mgf.4mg.com/new_airbox.htm
There are a couple of problems to resolve before fitting the box into the engine bay. These are:
1. making space for the air box. The diameter of the 'box is 180mm (200mm with the lid in place). Therefore it will fit- as my chimney ducting was 220 mm in diameter, and fitted with only a little 'squashing' However, to fit this 'box, I think that the original airbox support bracket will need to be removed, and the fuel filter relocated. Carl's done this for his airbox (as seen on Dieter's web page)- and should be reasonably straightforward. But after a brief inspection, the fuel pipes appear to be of rigid steel construction, so I wonder if Carl might shed some light as to how he moved the filter?
2. Induction pipe- between filter and throttle body. Tube will need to be 70 mm in its internal diameter. I reckon the 'box will need to be rigidly mounted (a' la ITG) so the tube will need to be a flexible one. Therefore two options: reuse the original soft rubber corrogated inlet tube or obtain some of the same stuff that ITG use for their filter kit. The latter would be preferable. I don't know where that is sourced from? Anyone know?
3. Pipe from nearside airvent to airbox. I can't recall the internal diameter for this pipe, but the K&N supplied ducts are too narrow. Needs to be something like 80 mm I think. Something suitable from Wickes? (Our old friend, the ali chimney pipe again!)
4. How to attach the air box to the car. The lid has a central vacuum hose sender for the MEMS unit. Obviously redundant in this application, so I have popped it out, and plan to use it to pop a bolt though to a simple bracket where the standard bracket currently resides. Since the lid just snaps on/off, removing the filter for cleaning will be a simple case of popping off the 'box from the lid after some simple disconnection of the induction pipe.
Should be pretty easy- but I currently still have the hard top on the car, and no where to store it at my flat, so this work will need to wait until I return to my folks place to store it in their spare room!
Yup, I definitely *WANT* ;o) the new TF on the basis of the test drive last weekend... but it doesn't stop me playing with my MGF ;o)) Besides, looks like we'll be buying a house shortly, so no funds for new TF :o((

Pretty much spot on Paul. The MS Viper and Yvo's Hurricane are of sufficiently light weight not to require external support- and therefore a more elegant design. BUT the problem with the cold air supply pipe means, as Gaz found, the pipe has two rather severe turns in it- shaped like an 'S' For this reason, I would argue that the side inlet airbox is a better design for the MGF's engine bay.
The ITG does mount onto a bracket. I haven't had a very close look, but the bracket appears to replace the existing OE filter-box bracket, with a re-location of the fuel filter (ie the same kind of work I alluded to with the Rover airbox above). Not sure whether the bracket on the ITG forms one end of the housing or not II think not, but am not sure)- might be an option for the Rover airbox mighten it?
|Thanks for the thoughts Rob, appreciated. I'm continuing to think about this. Might try and get hold of an air box from a scappy if i can persuade the wife to take me...*smile*. If the ITG filter does need relocation of the fuel filter we need someone out there with a ITG to tell us how this was done (or where the mounting bracket goes if not at the original location). Anyone with an ITG out there?|
