Answer to your question is yes. My question is why? 48 idfs are good carbs especially for that size engine, assumming that the combo matches. If your having tuning issues, list your combo so we may attempt to help u. Or is there something else? _________________ 2276 IDA's 86C 11-1 DD !

Well Im using this 1970 Fasty as a daily driver, and I want to remove a carb in an attempt to save a little more gas, since its ridiculous nowadays. I understand when driving a car like this, you can't really expect fuel effeciency, but things are tight, and anything helps. |

Gotta realize that removing one carb doesn't necessarily mean less fuel consumption. Dependant on the rest of the combo by just judging on the size and carb size/type, I don't think the engine is really designed to be a fuel sipper. The best of both worlds is to look for someone who's willing to trade up your 48s for 40s and maybe cash. Otherwise a well tuned engine can get you 18-28 mpg depending on driving style. _________________ 2276 IDA's 86C 11-1 DD !

Believe it or not, you can actually get better milage with dual carbs then a single when they are set up corectly. _________________ 2017 Street Comp Champion - Thunder Valley Raceway Park - Noble, OK

I get 27 on the highway with my 2442 and dual 49s....yes, 49s. Duals are much more efficiant than a single....[/quote] _________________ SEE YOU AT THE RACES!!!! |

So when you say, "set up correctly", what exactly should I be looking for? Im not extremely knowledgable with engines, so anything helps really. |

I once traveled 800 miles with a friend. He was in a 63 beetle with a 1776cc with dual single barrel solex's and I was in a 68 beetle with a 1904cc with dual 2 barrel dellorto 40's. He kept bragging about getting way better millage than me. but after the round trip I calculated that I got 44 mpg and he only got 30 mpg. I also spent less money on fuel and filled up less. He had to down shift going up hills and passing and I didn't, therefore keeping the RPM's down. |

If he had the stock geared 63 transaxle and you had the stock geared 68 transaxle YOU SHOULD have gotten better milage them he did. _________________ 2017 Street Comp Champion - Thunder Valley Raceway Park - Noble, OK

44mpg is very high, was this calculated of your speedo/odometer that was tested as accurate? _________________ (06:31:07) RoachGhia: "i drink dick way too fast" |

My engine only has 67K miles, and those 48s were brand new when the engine was built. Coming from someone with experience, how much do you think they're worth? And roughly how much should 40s cost? |

I know 44mpg is high. I didn't believe it myself. This was my first time travelling with this car. we drove down to the Great Canadian VW Show in vancouver. I live about 400 miles north. I made it about 300 miles before I filled up (I wasn't empty yet, and he only made it about 150 miles (he was completely empty). I drove into vancouver (about a 100 more miles), filled up the day I left, And then drove back home (another 400 miles). I actually probably drove a bit more than 800 miles with the driving I did in Vancouver. I remember only filling the car 3 times on the trip and then when I got back home. yes, this was using the odometer. |

Get your carbs dialed in first and get a shop to show you how. Or, go and read up on how to do it. You can get over 25+ mpg once u get them tuned up. Last ditch effort you can easily get 150$ + a set of 40s from the right person. But I implore u to get it tumed and synched first. There is reading material and thereafter a you tube video. _________________ 2276 IDA's 86C 11-1 DD !

carb sizing is the SAME for duals or center mount. A 48 IDF is HUGE and too big for most applications. _________________ It's just advice, do whatever you want with it!

Guys, he's trying to convert his Fastback, Type 3, to a single carb.
In a word.......no.
Dual carbs, in this application, are orders of magnitude better than a single centermount carb. BTW, with a 2276 and Dual 48IDF's what kind of fuel mileage were you expecting to achieve? Not being sarcastic here, just a straight up question. _________________

The person I bought this from put this engine in it. I was more interested in the car itself than the power, and the opportunity was just to good to pass up. I'm just trying to find ways to help my MPG out thats all. Anything helps. |

Do you know anything about this engine? Like, what cam it has in it? Type of heads, exhaust? I'm sure there's someone out there who would swap you some 44IDF's or Dellorto 40DRLA's for your 48IDF's - providing it's possible with your engine combo. _________________
