I just put a new 1955cc stroker motor in my bus using my stock carb.
Some Specs:
90.5 mahle B stroke p/c
76mm crank
stock cam
stock heads
stock carb
Vintage Speed Exhuast
this is in my 1965 Bus so the added torque is awesome. I have only had it finished for a few days but I'm loving it.
My engine compartment is not as clean as LHG but I'm working on it. He was the inspiration for my engine choice.

What kind of MPG's do you get with it? |

I haven't even run a full tank of gas yet. I drove it for the first time Tuesday night.
I will try and figure it out but my speedo is not correct so it will be a guesstimate. It runs about 10 mph fast (reads 75 running 65). |

Don't know how easy they are to find in the US but there are quite a few VW engines running on single SU carbs in the UK. Including a 2007cc in an offroad buggy for quite a while. Favoured for ease of tuning and supposed to be very good for torque and smooth progression...

Well if you are into VW Stuff you are into it to have something to fiddle with. Just like an old Harley. Thing is tuning engines just takes time, who said you can dial in one engine fasten than another especially when you have more carbs, more testing to deal with, oh yea, and expense, jets.... Point is it takes time to properly tune a engine.. Now if it is exactly a copy of a previous engine build you have built before, you may save some time.... Thing is you have to remember we are into VW's for the fun and rewards.
My 2110 w/single 44 Weber...... Hopefully will be a high milage engine do to build, Single Heavy Duty Valve Springs, 5,500 rpm limit... Note chassis intrusion that that does not allow Dual Carb application.... RB

Just for the record......a single IDF or drla is a dual carb.
That being said I have a 2275 SP in my rail with a single 40 kadron w/32 vent 269 duration 1.25 rockers 40x35.5 heads 8.5:1 compression. Pulls like a frieght train till 5000 RPM. Very reliable.
I have built a couple 1914cc engine with 34 pict carbs with great success. So much so That I no longer find it doable to build a 1600 for folks as the 1914 is just so much more fun and just as reliable and only a couple dollars more to build. Fuel mileage on the 1914 with the 34 pict is similar to a tired 1600.

Gary- What do you use for cams in these 1914's? Any porting work at all? I'm looking to build a low rpm torquer for a bush buggy and this sounds like it fits the bill, so any advice is appreciated. Al

I'd like to know this as well. The concept is very interesting and I may want to build one myself. |

Hey Alb I use the FK-41 Engle. We did a 1914 for Jason in the office here with a stock 34 pict a 009 and an Empi 2 tip and it ran great! he put 60,000 km on it with zero incedents and just regular oil changes. He hed just 1.1:1 rockers with the 34 pict but when he goes to dual carbs he will add the 1.25 rockers to really wake it up.

I hope someone can help me with my engine! I have a 69 bug with a 1914 cc motor that was in the car when we bought it, so I don't know everything about it. It had a stock carb setup--and ran fine--but we were advised to put a bigger carb on it. I bought a single 44IDF weber, since I was told that the duals were hard to keep tuned in Virginia.
I was looking for some power increase, but have felt zero % more power! Actually, my low end power is worse. Also, it would not start all last winter except on days that got over 40 degrees, which happened maybe twice. Also I seem to be getting maybe 14mpg. btw, I do not have heat risers, and if I remember correctly the guy who installed the carb said I didn't have to get different jets. It came pre-jetted for a 1600. Would the jetting be the problem? Should I get a different carb? My husband would be less than thrilled. |

A single 44 IDF is a good carb, difficult to tune and poor on cold starting compared to a stock carb, but a great carb none the less.
a 1914 with one of these should give you loads more go than a stock carb and the fact you are only getting 14 to the gallon should tell you that it's set waaaaay rich.
Have a look at what jets you have in it as you will need to re jet it, as sure as eggs is eggs. Whoever told you otherwise was telling pork pies (er, thats cockney rhyming slang for lies btw!)
your low end will suffer if the venturi in the carb is too big. You should be looking for something in the region of 30 - 32mm (should be stamped on it so you should be able to see if you look down the throat of the carb. then let us know what jets it does have and we'll go from there.
The reason they don't like cold starts is because they don't have an electric choke mechanism. Until the manifold gets warm, all the fuel condenses on the wall of the manifold and the engine runs lean. If you have proper manifold pre heat (see the aircooled.net manifold as a f'rinstance) the idle smooth out after a couple of minutes. When starting, try pumping the accelerator pedal 3 to 5 times before you turn the key as this is usually enough to get the juices flowing.
Best thing to do is go and get another carb and have 2 44's  Having duals would solve the idle problem certainly  but then you'd need bigger heads etc etc. Strictly speaking, a 44 is too big but seeing as it's only a single, you can get away with it but you do lose the bottom end a bit. It would have been better with a 40 but you don't need another carb, you just need a small venturi in there and appropriate jets. you jet to the venturi diameter, not the engine size

your jetting is so rich your plugs are fouled, that's why it won't start when cold.
I guarantee you the carb is improperly setup. Also, is your intake getting hot? Are the preheats hooked up?
A centermount is MORE work than duals to setup, because it MUST have proper preheat and intake if you want it to work. Duals do not have these issues.

I would not take any answer of mpg from anyone as useful unless they can also tell you fuel air ratios there running.
Most people with vw's seem to spend all this money and they just guess jet them.
I would bet over 30mpg is attainable but most will be getting low 20's due to lack of tuning , no manifold preheat, weak spark and overly thick engine and gearbox oil.

Thanks, it was rebuilt by a someone with quite a few years of experience rebuilding them from his garage. It has 1.25 ratio rockers with a TCS10 Tubo cam and a single dual barrel IDF 40. Lightened flywheel, full flow oil system, just added a ceramic header, Gene Berg oil pump, rebuilt stock heads, 8 dowel German 69mm crank counterweighted, Aluminum push rods, Empi Bolt on valve covers, Stage 2 clutch. AS21 1974 style case. |

If you go with a Single Weber or Dell you would have to keep the Vents smallish to get good velocity I think. This is the problem with a single. Had one a 1641 with 28mm vent did all the mods, drilled the throttle plates played with the jets and timing and got it pretty smooth with a small hesitation at tip in. Throttle response is slow with these and therefore a flat spot. It would be a good thing to get the Weber Manual by Tomlinson as it has a good article on setting up a Weber to run as a single. I would imagine though that a single Dell would be better as they have a superior progression port setup for the idles to mains. This I think would make it much smoother. There was a guy that posted here that had this very set up an said it worked great. Search for that. I would go no smaller than a 44 IDF or a Dell at 42 though and go to a 32 or 34 Vent. Most likely a 55-60 idle and a 150ish main, 165 airs. F7 Emulsion.

So has anyone successful built a 2017 or 2110 engine with single Pict 34 carb and have experienced great all round torque/power and good MPG?
With oil prices currently not going to go south, this would be a great option for those who want a stock looking engine upgrade that has a lot more go.
I’m sure many have built this kind of combo and care to share the modifications done on the PICT 34 to make it work on these bigger engines.
Thanks

In-ter-esting question!
I think from a general perspective making the engine larger ought to make most single setups work better!
The long intake runners are more suited for low rpm.
The main problem with many single setups is low velocity in the manifold.
Making the engine bigger fixes that low velocity problem.
As long as you want good power at reasonable rpms(lower than 5000 or so), the big single will be awesome.
Marv-I think in America single means one float bowl(americans make no sense at all)
(key to jetting single IDF/DRLA=small vents, divided manifold, special e-tubes SHuush! secret) |
Special e-tubes.. Tell me more! |

There is a picture in my gallery of the e-tubes I am running in my single dell
I do not know if it would work for all applications, but it was what it took to make mine work right |
