On the stand, nearly in, i have the nitrous bottle painted to match
Std 2l 71mm stroke crank
96mm B&Ps to give 2056cc capacity
H beam rods
Eurorace II grind cam
44x38 heads with dual springs
9.1:1 compression ratio
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
No leaks!! He's a witch burn him!!!!
I reckon with low profile filters you could get some twin carbs on there
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!

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.

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.

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.
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...
Is that Ironmans?
That will pull like a train from low down
Newly rebuilt 1641 twin 40 dells vintage speed exhaust it will do for now until I obviously want more power like yesterday
Here it is! Should turn the key tomorrow!
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.
