To '69, the cold-start was a second solenoid on the pump itself that threw a super-rich mizture.

70,71 had the squirter/fire starter in the stack

72-73 had a squirter in the bottom of the stack

Me too. been looking for these for a long time. I will definately play.

Sounds cool! I'm in if you do the amber fiberglass for a '73 mfi motor using original plastic stacks without needing mods. Keep us posted.

Me too. Put me down for resin.

Tom,
When i had watershields on my plastic stacks i had to drill 2 holes in between the intakes to mount the base plate. Not a real big deal, but you do have to take the stacks off to do it.

When did you get "Gretta"? You do realize that the name would work better if it was a Jetta.

MFI watershields
 

I would also be interrested in a set of mfi watershields for my 2.2! I also have the early spray-type cold start mechanism and would need a way of integrating that.
Please keep me in the loop too!!

I am also interested in the amber resin and if possible some way to integrate the 70-71 cold start system.

As an aside, has anyone tried the snorkel replacement that is advertised in Excellence for the early cars? Kind of expensive for a plastic "donut", essentially.

Oh, and my 69E ROW car has (had) the squirters as well.

Any ideas of pricing for these assembies?

Andrew-
How's the progress on this project? I'd still love a set.

Progress is ok so far - I have molds for right side (basically standard base plates & covers) now I'm doing up the base plates and covers for the 69-71 mag stacks - then the 72-73 plastic stacks. I was planning on doing a lot of work this weekend, but the shop I'm using is closed until Wednesday. I'll keep you posted!

No one mentioned an alternative to the K&N filter elements themselves. Is everyone satisfied with them? (I'm not; mentioned that numerous times). That was a rhetorical question. We have enough pro-con K&N threads already don't we?

I'd like to see a filter housing that could accommodate alternative filters (paper, foam). Alas, in my search for paper alternatives, not too many are interchangeable with the Watershield housing dimensions. However, you could design the molds to accept a wider range of filter diameters and maybe still fit MFI engines. Foam filters can be ordered to any size, but that'll require some inventory expense.

Andrew,
I am with Sherwood on the K&N filters. I actually use them on 3 cars right now, but I am interested in alternatives that offer higher levels of filtration without the high restriction of most paper elements.

If I recall the left side dimensions from my experiment, the filter element will need some mods on that side also. Is that what you are seeing? Are you providing for clearance on the microswitch actuating arm also?

If you need photos or measurements from a 2.2 liter S engine, let me know...

Thanks for the effort, long needed (this could be a commercial product, I would think.)
:cool:

As an aside, it may be worthwhile looking for a manufacturer that would make a paper airfilter that would be the same dimensions as the twin K&N replaceable units . Then others with watershields could put in paper if that's their preference.

Regards,
AM

It looks like K&N uses a metal clip to fasten the ends of the filter after determining the circumference needed for an X" diameter element. Other manufacturers could do the same if the potential sales volume is there (probably not). Foam filters can be glued together, which is what I did on my Amsoil-adapted filters in Filtron housings (similar to non-Watershield K&Ns).

Sherwood

How about those IGT (or is it ITG) foam filters?

cheers,

Jeroen

From previous posts, it appears they (ITG) recommend purchasing a blank baseplate, then create the three throttle openings, but offset from their regular centered position to accommodate the MFI components. The price point is a little north of the Watershields, but a lot of people use them. The unshielded top may be more susceptible to excess moisture (rain), but I'm sure a shield of some sort can be fabricated to block out most of it.

Sherwood

Any progress on this project?
 

I've got my car half torn apart for other projects. Just wanted to know if there is any progress being made on this project. Would rather spend my time and hard earned money on this instead of some of the other projects I've got in mind. Let me know!

Of the many FRP parts that I make, and that have been adapted to MFI with a cut and a metal brake line inserted for cold start...http://forums.pelicanparts.com/uploa...1065717995.jpg

the K & N style cover will suck 5HP from 6200 - 7200 on my 2.7RS so they are not a good idea. What I did was make my own flat covers, incorporating a cold-start squirter system. This is needed on pre-72 MFI systems (they were mounted on the filter assembly). I used a piece of brake hose, with one end crimped off. I drilled three tiny holes in it for squirters, just above each intake. It is held in place by 2 pop-riveted P brackets I made. It works fine, I have a manual switch to squirt instead of the thermostat (I hate automatic operations that we can do better ourself). Also only have it on the left side as both sides are not really needed, but could be added to the right side just as easily for starting in frigid weather.

I have modified my rain shields with a hole so that they can fit over these flat plates for driving in the rain. (these plates have the cold start so I must leave them on). The screws are JUST long enough.

Have fun!!!
