dual carb

[82charger2.2]

I was wondering about a dual carb set up. Wouldnt that be too much for a little 2.2? What are the positives and negatives?

[allmotor]

I ran them on my race car. the positives are i made a lot of hp. negatives is you need to balance them, they are not for street use and very expensive.

why not for street use? The whole carb thing is confusing, I think I'm just gonna go get a turbo engine, mod it up, then stick it in my car and get it over with. I think it would be easier and more cost effective to build a turbo car with loads of power than it would to have the headache of the carb.

If thats how how feel then sell your carbd charger and buy a factory turbo car. Its so much less work and hassle if you start with a turbo car. No offense intended but you dont seem as seasoned as some of the other guys here and I dont think you realize what you may be getting into. Like I said this isnt an insult as Im a novice as well having only 5 years experience w/ these cars, both turbo and non. After making a few mistakes myself and w/ the guidance of a few more experienced TD guys Ive realized that your better off buying a car thats close to where you want it then starting from scratch. At least until you get real comfortable with these cars.

I disagree with them not being for street use. I run a pair of Weber 45 DCOE's on my SC with a big valve head and solid lifters/cam. It's my daily driver and I rarely have to do anything to the carbs. If they're synced right in the first place, they shouldn't need to be tinkered with.

i'm running a .600" lift custom schneider cam, 103lc and 270°@.050", 14½:1 compression, dual 44mm webers. this in not streetable by any stretch. i lugs horrible below 3000 rpm so running 5th gear is totally out of the question. for the originator of this post, doing stuff like we did is way over his head.

yes, this is way over his head. but if you start a project do it with the newest/best technology. carbs are old tech, I would never use them unless it was required for a race bracket, not that I would race and if I did i'd find a better bracket. we don't run drum brakes on the front of our cars anymore either.

If you would run a more street worthy cam and less compression, it would be streetable. I think this fellow was suggesting a street setup as opposed to your race setup. I just wanted to say it can be done and it can be dependable. By the way allmotor, I bet that thing really screams up high in the revs.

it safely turns 8K, power drops off @ 7500.

I'm getting on here trying to see what would be best for me to do to my car for hp and still be a daily driver. What I wanted to know was if I could run the dual carb and still be a street car, not everyone wants a race car only. I'm looking for power and reliability. I'm new to these cars, I just purchased this car 2 weeks ago, so I dont know much about them, but to say its over my head is just kind of rude. Didnt mommy ever tell you that if you dont have anything nice to say, dont say anything at all.

82charger2.2-To answer your question, yes, it is possible to have dual carbs and have a dependable daily driver. Here's a pic of my setup when I was setting the cam timing.

Do you have to do a lot of modifying to get it to fit and run right? Is there any clearance problems?

[dcoe4me]

I went with the later, ZF power steering pump as it's a bit smaller and gives a bit more room on the passenger side. I use an air cleaner housing that I built myself, but there are plenty available on the market that will fit just fine. With the filter it is tight near the firewall, but I don't recommend you drive without one. Also, all the computers and emissions stuff are long gone. I use a Mallory Unilite distributor and an MSD 6AL to fire it. Not things that are a necessity, but really cleaned up the engine bay and added some performance.

[82charger2.2]

Thanks for actually helping me out. The engine looks really clean. How much power are you getting? Gas mileage must be hell with the two carbs. I was searching for a supercharger, but I think I might go with this instead, little cheaper and looks really mean.

Just out of curiosity, what does a stock carb flow CFM wise?

Continuing on.. a stupid question arises here.. would two carbs be what a single runs X 2? If thats the case, could i [theoretically of course] run one carb with the same CFM equal to that of running two carbs?

confused? me to i think lol
