Difference in Weber Carbs??

[Osiris]

Ive read thru the search on the Weber carbs and ppl are constantly talking about 38 DGES, 32/36 DGEV and some other stuff. What exactly are these numbers and which one is recommended for my car?

:sadwave:

The numbers are the size of the barrels at the throttle valve. The E in DGES and DGEV means electric choke (A would mean water choke). On the 32/36, the primary barrel is 32 mm and the secondary, 36 mm. It is a progressive type carburetor, in that the primary opens first, then when the primary is 2/3 open, the secondary opens up. This type of carb is good for gas mileage, low speed driveability, and performance on stock type engines.

The 38 DGS carb is a dual 38 mm barrel carb, where both barrels open at the same time. It has more air flow capability at any rpm, and can make more power than the 32/36 (assuming it's not oversized for your engine). The engine has to be built to take advantage of this carb (IHE and cam. Higher compression ratio a plus). This carb works on the street, but you have to use your foot to control the throttle opening at low rpms to keep from bogging the engine. At mid to higher rpm, it outperforms the 32/36. Hope that helps.

About 300 cfm for the 32/36 and 360 cfm for the 38.

DAMMMNNNN! Its like the clouds parted and the sun broke for the first time and i was enlightned. :bow:

:lol :lol :lol

Seriously tho that is a great explanation. I was thinking i would have to read post after post to understand it. Thx.

At the risk of sounding stupid tho, A20A1, what is cfm's now. And what do you recommend, 32/36 or 38/38 carb?

[A20A1]

Waco... why does that sound familiar?

CFM is Cubic FEET PER MINUET... Cubic feet of Air, rather.

basicly how much air the carb can flow per minuet.

LMAO. Waco is probaly familiar for two reasons. Remember 90's, Branch Dividians, FBI and all that crap. It happened here. Now some big name college basketball player is missing from Baylor University which is also here. Breathe easy tho, because im not from here. Military brat. (military child to those not familiar)

Still didnt get a recommendation on which carb to get tho. Plz help.

And thanx for the timely info.

[A20A1]

is it WAY-CO or WACK-O?

[Osiris]

I say wack-o. :lol Its really an ok town for older folks. Kinda slow but whatever. Im here for school (computer networker) and me and my family will be moving. BTW, i graduate next month from Texas State Technical College.

PS- Still need a recommendation on carbs to get.

[A20A1]

depends where you're moving... :D 32/36 is better for emission controlled states. where as 38 is good for kewler states.

[Osiris]

Its either between somewhere else in TX (dallas probaly) and Atlanta GA. Do you know if either is an emissions controlled state.

And the 38 seems to be trouble. Something about holding the gas to control throttle or something.

[A20A1]

no trouble... the 38 is actually a much cleaner throttle for the carb... once and a while the 32/36 might get stuck up and the secondary won't open all the way.

all he's saying is you need a little finess when you press the gas pedal... and turst me you'll get used to it after a while.

[Osiris]

Texas an emissions state? GA?

[A20A1]

What? What?

[Osiris]

Sorry, Is texas or georgia an emmisions state. Meaning can i get the 38 weber carb in TX or GA? Also which is recommended for a newbie to carbs? Or is a carb a carb?

[79EK1]

You can buy either carb over the internet, so availability isn't a problem. Whether or not you have an emissions inspection and tailpipe test in Texas is something you'll have to find out. In California, neither carb is legal. It will fail the visual inspection immediately and they won't bother with the tailpipe test. If you don't have an emissions inspection program where you live, then you can use either carb. Which one depends on the mods you have to your engine. If it's basically stock, or if you have an intake and exhaust, or you want better gas mileage, then go with the 32/36. If you have a header, exhaust, hot cam, higher compression, a stick, and don't care about gas mileage, try the 38 DGES. The other thing to think about is that there are more people on this board with 32/36 DGV carbs than the 38 DGS, so you will have more support for that carb. Finally, the 32/36 carbs are less expensive and can be acquired in kit form. The 32/36 DGV is a great carb for newbies. I would say that the 32/36 is your best bet. Good luck.

Thanx 79EK1. Probally will take your advice and get the 32/36 and maybe get the other one later.
