Id imagine the left hand carb should clear the eber Get someone whos allready got twin carbs to have a measure up for you so you can see if your likely to have clearance issues The most common upgrade for twins on type 1 engines is weber 34 icts Better can be had for more money though
Is it your own work? If it is then i salute you If not you must tell us whos work it is as this sort of thing makes me moist in my modding fingers
If i could do this Paradox, i would be a happy man, unfortunately not, this was the work of Darryn @ DC Customs, Dudley, i did the re assemble, not quite a claim to fame
Loving the tinware. Do tell us your engine spec, we lawnmower powered bus owners get some ribbing on here.
Air Cooled Type 1 2110cc motor, Increased bore & stroke. It can go a lot faster than you would want to drive a bus at. I have never been overtaken by another camper in it! It won't beat a scooby bus off the line or for top speed, but it won't suffer water related breakdowns either! 80mm counterweight crankshaft 200mm stock weight flywheel 90.5 barrels & pistons Total seal piston rings Mofoc0 40x35.5 valve heads Balanced crank Web III camshaft Scat cam followers Balanced conrods 8 dowel flywheel to match crankshaft Barrel spacers Swivel feet valve adjusting screws Dual Thrust Cam Bearings, steel backed 200mm clutch centre disk 1700lb kenedy clutch cover plate Full flow oil thing External Oil Filter Built by Harry Harpics who know what they are doing, i don't! Standard Heat Exchangers (for now) VW Speedshop Stainless Steel Turbo Muffler 2 ½" (for now) Twin Dells Engine set up on rolling rd for optimum performance between 2-4k revs, rather than full on speed 20 mpg (once at least) 100s of smiles per gallon I'm hoping to come to Techenders this September. If you are toying with the idea of an aircoled engine upgrade then i will happily take you for a spin.

1641 with progressive carb and preheated air using slightly hacked stock air cleaner. And JK stainless single quiet pack exhaust. Tuning using permanently fitted PLX wideband sensor. Full flow 26mm oil pump HP-1 filter and 12 plate oil cooler in underbelly air scoop with mocal thermostat sandwich plate. Fitted to help clean up the metal filings left behind when I left the flywheel gland nut undone and ended up with an eight dowel crank because four holes were elliptical. Crack in engine block oilway actually blocked with JB weld ... 70mph in 30 degrees C air on autoroute to Bordeaux last week, oil at 115 degrees C.
2007cc (78X 90.5) Engle 110 cam 40IDF carbs heads are semi-hemi cut 041s with 32x35.5mm valves, three angle valve job, by John Maher heavy duty rockers and pushrods stock balanced conrods bottom end dynamically balanced 200mm clutch with stock disc Deep sump, Berg 26mm pump and cover, Fram filter, Mocal thermostat and 16 row cooler under the cargo floor with high power fan Welded and balanced fan Home made breather box Stainless 4-1 JK header with single quiet pack Built and installed by Harry Harpics. This has been a gem - after 10 years and nearly 50k miles, with only a flywheel oil seal and new float valves and spindle bushes in the carbs (which were second hand). It pulls a 4 wheel tilt bed trailer with a car on it all day at 60mph (e.g. to Germany and back in a weekend) and when not towing it will out accelerate many smaller modern cars. Fuel economy isn't much worse than stock either: 22-24 on a run if you keep it at 70. My only complaint is the noise - despite lots of soundproofing, on a long run it is tiring and if you play music, when you slow down you realise its at deafening volume. If anyone has an exhasut system which flows better than stock but is quiet, I'd be interested to hear about it. I also keep thinking about building my own airbox using blow through turbo carb covers. CSP do any airbox, but for £800 I'd want a totally silent van afterwards!
A previous owner built the motor in my bus. He got in touch after I put it in eBay last year in a moment of madness and gave me a list of spec on it but unfortunately I've just looked and it seems eBay don't store messages for that long so it's gone it's a T1 and I remember him saying it had big valve heads, and a 2litre type 4(?) gearbox, as well as the twin 40's, some fancy dizzy and coil (I think) and that it's been bored out to 1676cc (again, I think). I had it set up on a rolling road due to a fuelling issue and it dyno'd at 88hp so it shifts pretty well for a lawnmower motor and isn't horrendous on fuel...about 26mpg
This motor is sitting as I write this in my garage awaiting fitment of newly powder coated tins. 96x71mm bore/stroke (2056) 41x34mm valve size to keep the low and midrange as strong as possible, bigger valves will only gain in upper rpm. 8,5-9:1 CR JPM custom designed cam JPM 7075 billet dual taper pushrods IDF 40mm, 28mm main venturie. Phyton CSP 42mm exhaust. I think its going to work well! Should start tomorrow getting it all buttoned up. Should be running by next weekend hopefully...
Newly rebuilt 1641 twin 40 dells vintage speed exhaust it will do for now until I obviously want more power like yesterday
This seems a bit small? It'll be torquey but run out of puff above 4500rpm is my guess. I think you'd get more power with 30's.
I am actually now looking forward to the end of summer as I am finally going 1776 for my . Some good inspiration here.
