reversing air flow


Ren? Pohl

who said it is a bad idea to reverse the airflow? Actually the Amphicar
factory was trying such experiments themselves, found it to be a better
solution, but unfortunately changes never went into production! But you
would have to change the in- and outlets on the bonnet, find a suitable new
opposite fan and ... - and this is the major problem - find a solution for
the transmission cooling. According to the factory experiences the
transmission went much hotter that way, so you would have to add an extra
transmission oil cooler. Some German drivers tried to cool down the trans by
cutting in air intakes in the upper part of the side panels right under the
rear windows. The effect was doubtful, however no good idea in rough water.
So all those holes are taped over meanwhile.
Installing an extra trans cooler shouldn?t be much problem, if you take an
electric oil pump from scrap out of a modern car (the Audi turbo got such
for example). Use the plugs and oil level points to fit the hoses. But you
know, if you drive it just for show, it might be not worth all the
Generations tried to optimize the Amphicar, but at the end after many years
playing around and uncountable changings and tries, they all restore it back
to originality!
