Don't remember exact numbers, but running a water pump uses less horse power than running the fan to cool the relatively�small displacement, low�HP engine.� A 10% increase is a big deal. This was stated in a car mag in their report on the new powered Vanagon in 1983.� Maybe a dedicated list member could Google it...
Not sure if this was the reason,�do 1.9 Vanagons have much more power than the air cooled?� I'm a VW noobie (8 years), not steeped in the rich tradition and lore of VW history.� Still doesn't explain why they didn't go to a in-line 4.� I'm sure there's more to this story.

So my basic question to this list -����� does anyone know about why
VW decided to create the WBX, instead of changing to inline-4 in 1983?

Here is what I have found so far:
"The switch to water-cooling for the boxer engines was made abruptly
mid-year in 1983 because VW could no longer make the air-cooled
engines meet emissions standards"

Happy driving
