Look at my sig and avatar for what I drive.
Guess you missed the bit about the bored and stroked 2.0 type1 built from a 1.6 for over 80k in a hightop camper?
Sorry, but I speak with over 20 years of experience with AC engines.. and many others.. in extreme conditions.
2000rpm moves less air, but engine also generates much less heat then 4000rpm... fan doesn't need to move as much air because there isn't as much heat. I'm not suggesting putting your foot through the floor at 2000rpm on a long hill. I'm saying in slow traffic conditions, there is no need to rev engine... it only burns fuel. A properly tuned engine with properly maintained stock cooling system can idle for hours without overheating.

i wasnt referring to your motor but to the original posters question.
neither was i questioning your knowledge of Aircooled engines.
i was merely passing advice about not labouring an Aircooled wedge and dont be afraid to rev em
if i have put your nose out i apologise....

Run an econimical banger just for getting places cheap and try to use your van just for vanning or when it provides accomodation as well. If you only run a T25 think about it in terms of a big lovable dog: Eats like a horse and needs vet money too often but you love it in spite of all that.... Well you must mustn't you!

I wasn't referring to my motor. I was talking about rpm being needed to keep them cooling properly. There is no need to rev them to keep them cool. Other posts back up my opinion.
And my nose isn't out either.
Would be fun to tip a few pints and talk engines sometime.
