first, down draft carbs are mounted upright (this is the common type, found in carb cars like 1.3 corollas), they suck air downwards

side draft carbs are mounted on the side of the engine, suck air from the side

twin carb (or dual carb) is a carb assembly with 2 "torotot" each

example of twin side draft carb:



so a 4 cylinder engine with twin side carbs has 4 torotots

Common brand name of Twin side draft carburator are Weber , Solex , Dellorto , Mikuni .

my project is putting a downdraft to a 4K engine to have better sound and little addition in performance, someone told me that twin-side will add more performance in 4k engine (1.3L) and it will become 1600cc, but it will sacrifice more gas consumption is that true? the down draft is good for daily use is that true also? my project is having 4k engine 5 speed, down draft, 4-2-1 with muffler at the end and put it in a owner type jeep, what you think sir?

[uls]

a stock 4K already comes with a down draft carb

what do you mean you wanna put a down draft carb on a 4K?

it's already there

unless you mean you wanna replace the stock carb with another downdraft carb

twin side drafts will give you more power and increase your fuel consumption

(kaya nasabi sa iyo magiging 1600cc)

they suck in more air and spray more fuel

but dual side drafts are harder to tune than stock carbs

[akosidom]

ah ganun ba, how about changing the stock down draft to mikuni or solex?
4K engine have a stock down draft and it is only 2 right? how about adding 2 more to make 4 down draft? do you think it still fuel efficient?.

since we're talking about carbs

this is beautiful



6 Weber carbs

12 torotots

it's a Ferrari

[akosidom]

sir. look at this one another 2T engine but what's carburetor is that a down draft right?

[uls]

yep

that's 1 down draft carb

other 2T engines have 2 down draft carbs (twin down)

--

slight correction lang sa sinabi ko yesterday

pag twin down or twin side, it means a 4 cylinder engine has 2 carbs, either 2 down drafts or 2 side drafts

twin doesnt refer to the torotots

sorry for the confusion

[akosidom]

yup sir. thanks ng marami yan i gain another one from you, that will be my plan installing a a bigger carburetor, one torotot at the top and exhaust system from nodalos.

[akosidom]

[akosidom]

sir. anu yung nasa valve cover ng video na hitman of caloocan, like a small filter? what's that

[mazingerZ]

Pardon my ignorance mga kapatid, wala kasi akong idea how a carb system works, pero judging from the pics on this thread, wala po bang air filter ang kada trumpet na yan? Because di ba me flying saucer ang mga carb engine?

Pwedeng open, pwedeng may filter. Pwede rin hindi flying saucer filter, kasi pwede lagyan ng tube papuntang cone filter na malayo sa carb. Pero syempre, K&N-style flying saucer FTW.

*4G33 question...

Matipid naman yung sa Lancer namin. 4spd, naka headers. Nung gumagana pa yung speedo, nasukat ni lolo na nasa 10km/L yung gas mileage nya.

Pix from the Interwebs:

4G32 with twin-down and something like a CAI


Stock 4G32 with flying saucer



Eto pa flying saucer, pero aftermarket

[mazingerZ]

Okay lang po na walang element ? Di naman nakakasira ng engine?

[roberto_minosa]

As much as possible, dapat may air filter. Pero ang ganda ng tunog pag open.
