After reading many many topics here on the Samba, I'm getting the idea that the Aircooled Vanagon isn't getting the love and appreciation it deserves. Many believe they are slow, unreliable and can't climb a bump in the road. On top of that they are heavy drinkers. So far the believes ....

Here is my story.
Last week I went on a 700 km trip from the Netherlands to the Belgium and French Ardennes (and back). That's the place in Europe where they didn't adapt the roads to the cars ...

With an almost fully loaded Westy we did extreme U-turns, climbs of 15 tot 21% and it never came below 70km/h (in 3rd) and almost always could hold 80km/h in 4th. It never gave a glitch or lost any parts.

The first half of the trip it did 8.12km per liter on regular gasoline (19 mpg). In the Ardennes I changed my vacuum curve a little with the result that it did 8.94km per liter (21mpg) on the second half. I must admit that the last 150km were down hill or flat Very Happy

Yes I did some work to the engine but it's all finetuning and decent maintenance. No major changes.

So if you give your Aircooled Vanagon a little love it will give you a lot of Aircooled Love back. Even without breaking the bank (Very important because I'm Dutch Cool ).

It sounds like you've really got that AC engine dialed in perfectly.

Yep.
Super smooth running engine with torque over wide rpm range. Starting at 125Nm @ 1500rpm, 148Nm @ 2500rpm - 3500rpm and 125Nm @ 4500rpm. Horses peaked with 82HP @ 4300rpm.

Nice report, sounds like a great trip. Good to hear the air cooled is treating you right.

You get back what you put in. I feel like more people need to learn this.

Wow! 82hp in an aircooler!?! That must have been big $$ for that build. My stock aircooler (67hp) does struggle with grades, especially when loaded.

To the OP:

Here in most provinces and states in North America, we would not be permitted to replace the EFI with the dual Weber carbs due to emissions testing. The air-cooled engine gets additional cylinder head cooling from the evaporative cooling that carburetors provide. The Ardennes and other locations you are lucky enough to travel to are all generally much cooler climate areas than, say, Southern California, just to name one major area of Vanagon Westfalia vehicles. You also have much better fuel quality in Western Europe, especially higher octane petrol, which allows a tune with higher compression ratio and a more aggressive spark advance curve or map. In short, those locations are where the air-cooled engines experience ideal operating conditions.

Over here, the fuel, ambient heat, OEM design features (like EGR, very lean AFR in the EFI system), lower quality gasoline, and the high speed expectations of freeway travel all conspire to make the air-cooled Vanagon experience a short-lived and slow one. It is truly shocking how much difference ambient temperatures can make to the air-cooled Vanagon.

Your torque and horsepower figures are excellent! Could you share more of the details of your build for those brave enough over here to try a performance 2.0 AC build?

This is the best thing I've read on the internet today! This post makes me want an orange Bay Window Westfalia with your same motor.

My setup:
    - untouched shortblok (original hydraulic CU cam) because this was already overhauled by previous owner
    - new AMC heads with stock (39/33) valves (because the originals were cracked and valve guides came out by themselves)
    - completely disassembled new AMC heads, checked all parts (all OK and within specs), only gave the valveguides a bit more clearance (too tight)
    - ported heads and manifolds and reworked combustion chamber around the valves
    - reworked valve and valve seats (3 angle)
    - compression ratio to 8:1
    - new valve train geometry with new pushrods and Porsche swivel feet adjusters
    - short CSP manifolds (To let it all fit under the decklid)
    - Dellorto's DRLA 40 with 32 venturi's with vacuum connections (because the original Solex's where leaking all over the place and one housing was severely cracked)
    - velocity stacks
    - original heat exchangers
    - Vintage Speed exhaust
    - MSS Central Airfilter (Expensive, not absolutely needed, but takes the breathing noiselevel down and looks cool Cool )
    - 123Ignition Tune distributor (with vacuŁm connection) + Bosch spark plug wires + NGK BP6ET
    - Dellorto's and distributor finetuned on rolling road
    - Vacuum curve finetuned during last 2000km

Some pics and info can be found here: http://www.shoptalkforums.com/viewtopic.php?f=1&t=143948 posted under the same name.
