Double 2150's on 200 log - linkage question

I'm looking for help in setting up two 2150's on my 200. I think I've figured out how to mount them reasonably well (found a machinist who will fabricate a 1/2" base plate that I can mount directly to the log) but I haven't thought about linkage yet - or at least not in much detail.

Ideas?

Sketches?
 
Feeding the log with a pair of 2150's is too much airflow in one place. You'll need to divide that plenum to get decent velocity thru the carbs.
 
:cry:

Crap. That would mean too much modifying for me.

Well, I guess I'll have to stick with just using one 2150.

(Multiple carbs just look so cool :cry: :cry: )
 
I totally agree. It's sort of like making a 390 cfm carb into a centre squirter with a one to one linkage. Jack is on to it. If you service the engine as two 3-cylinder 100 cubers, then the .98 venturi 2100's will be fine. You just have to do some networking with PonyCarbs or the Schjeldahl bros at http://falconperformance.sundog.net/about.asp.

The jets, in the original 221/260 installation are looking for around 110 or so net hp to supply, and unless you are looking to make a 220 hp log burner, then you'll have an oversupply of fuel by about 30%. If you could profile each of the main jets to discharge about 220 cc/sec at wide open throttle, you'd have avery pleasant ~160 hp engine. The idle jetting may be too rich as well. If you could do the mods to fit two Holley 54 jets, then you'd be onto a winner.

If anyone here is aware of how to re-jet Motorcraft carbs stang200 could be yet another pioneer in making the log cut some lumber!
 
As far as I know, you can not re-jet the motorcrafts, at least not down in size. You can go up in size, but you'll only be able to do it one way. SO you have to make sure you do it right.

But then again, I don't know.

:hmmm:

If you had a jewler as a friend, then drilling each jet, and bushing with a new brass insert with the sugested hole diameter, and 90 and 60 degree chamfers with the correct throat length according to the charts in Holley carb bookes. When anyone drills a jet, the taper entry changes, the flow often drops.

With a set of jets in an around the 50 to 60 call sizes, you could measure the dimensions and chamfers min thou and degrees, and duplicate.


Sorry to get technical.
 
Hey guys, I have two 1.08 2100's. Do you think if I mount them to an adapter, say a Clifford type 2x1 (tunneling effect), and place them at cylinders 2 and 5, wouldn't this work. I mean the V8 guys use spacers and high ram intake manifolds to increase air flow and create a better fuel mixture before entering the cylinders, right? Or am I off?

Slade, maybe those .98 would work as you mentioned. Wish I had some to play with. :lol:

Now how can I divide the log without ruining it....hmmm....
 
Check www.vintage-mustang.com

Post in the wanted section, you'll probably have a couple of replies by the end of the week for .98 venturies.

Personally, I would mount them using a cliffy. too much air flow restriction. You are right about the risers, but that is different then the adaptor. the risers don't restrict the flow like the adaptor does. If you are going to hack you head, might as well do it like geezer did. make an adaptor plate for a 2V, let the entire carb feed the log.
