Technical Induction kit help!!!

[ronnieronson]

Bit embarrassed about this actually, but I'm stuck!

Got one of the mpi induction kits off ebay - it came today, and naturally I want to assemble it as much as humanly possible tonight

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180204395772&ru=http%3A%2F%2Fsearch.ebay.co.uk%3A80%2Fsearch%2Fsearch.dll%3Ffrom%3DR40%26_trksid%3Dm37%26satitle%3D180204395772%2509%26fvi%3D1

So here's as far as i've got:

and here's what i've got left;

elbow:

What goes one here???

some sort of reducer thingy:

4 jubilee rings (Large)- 2 of which I can suss out - and I'm guessing the other 2 have something to do with the sleeve thing?
The smaller one I know joins the hose to the vacuum hose that i'll be pulling out of the bottom of my airbox.
Also two bits of metal? what's the deal here?

...not happy that the seller didn't include any build instructions, although the quality seems to be pretty good

Any help here would be much appreciated

remove your current airbox.....does the 90 degree bent fir on the trottle body? I suspect not, and that what the reducer is for. Theres another jubilee clip used for ya

Don't know what the hole is for, no idea. Surely shouldn't be there

thought as much... its sorta the right size for attaching the vacuum hose - but obviously there's already a bit for that on the metal tubing...

 

[GoBe]

The metal strips are security mounts and you'll need one of the 4 larger hose clips to hold the pipe to one of the strips.

That thin hose leading off the main tube is for the cam breather not a vac hose.

cam breather...vacuum hose... it's all good - I know where it's going
It's the hole on the elbow that worries me!

What do you mean about the security mount? where am I meant to put it before I clip it to the pipe?


Here's an update:

 

[GoBe]

Well this is a focus kit that someone worked out fitted the MPI Sei.

The metal brackets probably best locate to a bolt or something on the coil pack tray.

ok cool - will look around to see what lines up well enough on wednesday when i fit it.

What do you reckon the hole on the elbow is for?

 

[randomizered]

i don't think it should be there. You could just block it?


Kristian

 

[GoBe]

Some pipe on a focus that doesn't exist on a Seicento. I'd get a slightly to big bolt and screw it in then a hose clip it.

 

[Brooky]

Ram a fat screw in it and block it up

looks like hes upgraded the kit so you dont need the other hole with long thin pipe no more, but put it there anyway.
motorfactors do a blue conector that would fit that hole, be better used then block the other one i think

the think pipe goes direct to the throttle body doesn't is

Got my mpi inlet on the garage floor but can't be bothere to go ouside lol

The only problem I can see with the kit,is that pipes diameter are too large for the little 1100 engine, it is not good for air flow....

Actually, the Focus kit is very good indeed on the 1100 MPIs.

bigger pipe = more space = more airflow = faster combustion... within reason

nice one

Think dave has it wrong

The crank case breather has a black pipe connected to it.

The one output from this pipe goes to;

a)the intake after the main filter. This is the bigger longer pipe, and links to the long blue pipe you have

b)the manifold intake AFTER the butterfly. This still comes from the crankcase breather, but is the much smaller diameter tube. This should not to to that hole on the elbow.

Looking at the picture, the blue pipe joins the stock crank case breather pipe, so you retain the stock mall pipe connection anyway


For a neater installation, you could remove the black breather hose, clamp the blue pipe directly onto the crank case, and block the small nipple on the inlet. (you do this with the k&N i seem to remember) and I also did it on the 16V. Its not really required.

Just to get it up and running, block that hole with anything you have to hand. A screw wrapped in ptfe tape, a bit of duct tape. There will be no outward pressure there, as the engine will be sucking all the time or at atmospheric pressure at WOT.





With regards to pipe diameter, and induction. It IS an art lol. If you look a the gsr mpi kit, it has a very small section.

Smaller tube generates increased velocity, and larger tube creates slower velocity. All these factors affect the characteristics of the induction kit. I'm sure it will be better than stock, even if it isn't optimal

I also just have a largish tube on mine, too much hassle messing with hoses sizes and no way to quantify it.

Cheers,

Kristian

Bigger is not alway better
Fluid Mechanics can verify for anyone believe the opposite.....
Also the air need to have an optimum velocity (Dynamic pressure) when enters the throtle , with such a pipe diameter i doupt about it...

Also the less angles the better, i can see two angles with no reason , the only angle needed is the 90 of the big hose to the throtle body.

At the end of the day mathanas the focus kit, which this is, delivers most of the performance the GSR kit does but at around 1/3 the cost. Yes it's not ideal but it's certainly an upgrade from the stock airfilter.

got rr charts of the the focus kit, ? i would say it dont zap power away like a K&N but having the same gains as a grs :chin:
