Ever see how the horizontal fan works on a corvair? Maybe something like that could be done... and better engineered and driven from the bottom. http://www.ponyespresso.com/turboengine.jpg
What about ditching the belt driven fan and running a electrical motor driven fan? Sure would get rid of a lot of monkey motion.
The one change I will make to the 993 is to have a horizontally mounted cooling fan like the original 912 engine. I'd appreciate any thoughts on how to do this. I have seen some photos of more contemporary flat-6 Porsche racing motors with a horizontal fan - anyone know how this is driven, and what shrouds might be available?
Mark, thanks for your reply - sounds like there are some 917 fans on this forum!
Howard, in response to your post - yes, this is an aluminium tub, but only from the firewall forward. The rear of the car is still a tubular space frame, approximately fitting the original 917 chassis, but designed to exactly match the original car's dimensions.
Any other 917 builders out there?
what your looking for is a 935 fan. If you could find a 935 parts book, its all there. I belive its almost 200 separate pats to make this up.
Thx Fran, but I certainly can't take credit for the pic. You did catch the link to the others, right?
I've seen the openness of the 962/956 engine bay but can't confess to having seen that of a 917. I'd imagine it's a bit tighter around all the tubes...
