1) What carberator are U using?

 

2) How well dose it work off road?

1 Current Weber 32/36 DGEV

2 Works great offroad. The only difficulties I experienced were when I was still working the bugs out.

 

1 Stock Hitachi carb

2 Compared to the Weber, it didn't have as much power at any RPM. Never gave me any trouble though.

1) hitachi, removed emissions

2) no real off road, but does great in snow and street 20ish mpg

Weber 32/36

I have it jetted rich for my engine, its going on a new one, that should be in and running friday, it seems to do really well, but dosn't like backwards to anti-clockwise cookies

You already know but to get it in the open, Carter/Weber Single Barrell off a ford inline 6. Tons of bottom end torque but like a motor to 6 grand.

1. Stock Hitachi

2. Not much real off road - putzing around - does fine OK on highway but no real dynamo - wish I didn't have to contend with IM, I'd have a weber on it in a flash

Matt, why don't you convert to a Weber but save all the Hitachi crap to put back on to get it I.M.ed?

 

It would be a snap if you had a spare intake manifold, then you could just swap complete intake setups in a matter of minutes.

I got a Hitachi

 

Doesnt really have too much problems.. My cutting out on left hand turns stopped happening.

 

Other then that it works fine..

 

Soon to be de-emissioned

we already had a weber on matts car, and that ford carb is doin' us alot better in the hills(dont have to worry about the deq people)

i'm runnin a hitachi that works good unless the venturi is fallin out(thanks to adam and some tape it works better now):burnout:

here everything differant

 

first the gas is very expensive - about a 1.15 $ per liter!

second, the exzhost reqwayerments are much easyer.

 

i never had any problems in sloaps.

 

i will check the carb 4 detales.........

i love my hitachis. after trying two webers, and having nothing but trouble, im gonna stick with the stockers.

It don't

My Brat w/EA81 and a 32/36 Weber with some exhaust work pulls very well at low RPM.

Remember, carb is only part of the equation

for

if you put it in, you must let it out.

hehe is that a 4-barrel skip? sure looks like it, lol hmm time to mount a 650 edelbrock to my hatch, lol...

 

 

my ea81 hatch has a stock hitachi.. 32+ mpg

starts, runs fine, no offroading in it..:D

So no one has tried a solex off of a bug?

Not Solex but 40DCOE weber40.JPG

 

Somebody mentioned trying twin SUs or Strombergs?

Still on my list as I have several of each.

 

Didn't Holley make down draft 2 barrel they called

"the Bug Sprayer"?

500 cfm orsumtin?

  • Author

Yup! Don't remember the size, but they are "Unubtaniom" now.

Hows that side draft workin' for ya?

I ran a Solex 34 for a while, which was better than the Weber but still not as good as the Carter.

a four barrel WEBER!! none the less.

Mounted on a modified SPFI manifold.

Rock and way too radical

 

pic please!:eek:

giant parts washers! how could a 4 banger ever use a 4 barrel, will you have to solder all the jets closed? 4 barrels on a subaru has to be some sort of joke, concidering without a turbo, you can only get up to 150 hp tops. thats alot more cfm than you need.

please explain skip

heh... if skip can run it, then it will work on a soob. lol you should know that by now..

 

my question is, how am i gonna mount a 4-barrel on my hatch? hmm..

 

although i am partial to my 32+ mpg.. me thinks with a 4-barrel i'd have my foot in it too much gettin about 12mpg, lol..

The trick is picking one with very small primary throttle bores (like this one) The small bores allow the in coming air to move plenty fast enough through the main venturies. Jetting the mains is just the same as jetting and air correcting one big venturi.

Mike W's using a big ONE and his tip on using the larger dia. SPFI manifold helps cut down the restriction in the manifold thus allowing more air flow.

I believe the Holley I mentioned above had the two monster bores connected via a common shaft. Read both barrels open simultaneously, causing a much lower vacuum to be formed at the venturi. (It had a monster accell pump to over come this).

The secondaries open via linkage on this carb. I do not tramp on it or it would fall flat on it's face. One would have to incorporate an AVS (Air Valve Secondary) to do this or a double pumper design. Evan then your comment on engine volume requirement comes into play -large time.

With this

you have to "sneak up on" the secondaries.

Allowing the air volume the engine is requiring to be high enough

to keep the air moving through the seconday venturis high.

Jetting/air correcting them is the same. Plug cuts and testing.

Thus the comment "It Don't" Off road, as this carb would be the pits.

As for fuel econ, stay off deep jabs with the loud pedal and it's not much different than a 32/36.

Now we move into the arena of variable venturi multicarbs, SU's or the like, these were found on many "Blokemobiles" TRs, AHs, Jags ect.......

I hope to experiment with these soon.

 

 

I sure hope Al S. chimes in here.

Weber 38/38 DGES on modified SPFI manifold on stock EA81 with free flow exhaust. Makes lots of torque down low. I still haven't corrected the jetting so it's running rich and therefor the fuel economy is currently dismal. Should be getting mpg in the low 20s when it's tuned right. This summer I'll probably put a 32/36 on the car to pass emmissions and at that point I can do a halfways scientific comparison of the two styles of Webers.

Stock carb!

 

Has problems restarting on a STEEP side slope.

I Wish mine was injected!
