QUOTE(Maltese Falcon @ Apr 1 2020, 06:28 AM)  QUOTE(mb911 @ Apr 1 2020, 05:23 AM) Marty how does the fan rpm exceed the engine rpm down low and then drop 1000rpm slower the crank rpm up top? Ben, Excellent question for the Ludwigsburg brain trust (IMG:style_emoticons/default/smile.gif) The specs are from Porsche customer service (kundendienst) and even they need to be accountable for information passed to us. I figure that there are enough 935, 962, private engine building shops around today...maybe a few will chime in here. My thoughts was that the elasticity of the guibo was causing the phenomena of the rpm/ differences. Marty Interesting.. Do you have a picture of that part by chance? |

The RPM problem is a typo. The 7000RPM should be 9000RPM
The Giubo has the flexibility to absorb shock, but it does not allow slip. All of our 914's have a Giubo of a sort in our steering shaft; the rubber joint. Here is an example of a Giubo joint used on the 917 driveshafts. Attached image(s)

My bud Jim in SoCal who builds, maintains, and races vintage 935/962's can supply you with his race proven horizontal fans. He builds these in his machine shop...and they are as good as the real McCoy; possibly better as you would otherwise be buying a very well-used antique. Porsche factory Race Dept. NEW prices, possibly In$ane.

Thanks for flipping my car Marty. I can see that a trip to So Cal is in my feature.
Maybe you should do a black and white car show… |
