I took some pics of my wheel fans, how they mount etc.
Ill post them here instead of hijacking that 917 thread (IMG:style_emoticons/default/rolleyes.gif) This is the threaded insert that mounts in the wheel center. Attached image(s) |

Are these still made? Or do you need to bottom feed at the junk yard racers supply?

Tim,
Those studs look a little on the short side (IMG:style_emoticons/default/smile.gif) Thanks for the pictures, I never knew how those mounted..... |

That "fan" setup doesn't exactly look like it moves much air.

I would have to say that I think that the straight blades on these fans would be designed to create turbulence and not have to move large amount of air. Heat is discipated faster under turbulent conditions than it is under laminar flow.

QUOTE(Mueller @ Jan 20 2004, 07:24 PM) Those studs look a little on the short side ... now you know why he covers them up with a fan ! i think the straight fan blades work just fine - Porsche and BBS have access to wind tunnels for testing... i wouldn't count on them being super-effective all by themselves - but recall that they're used on cars that already have been equipped with substantial ducts to the eye of the rotor - that aren't quite enough. so there's a nice supply of inlet air - you just have to encourage it out, and i believe the centripetal forces would work just fine. even at race car speeds, they don't turn much faster than 3000 rpm - they don't have the issues turbocharger pinwheels do. as a side benefit (pardon the pun) straight vanes don't care which way they turn, and you can mount them on either side of the car - fewer spares, one less thing to get wrong in the pits ... |

Plus, they cool in reverse as well. (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/lol2.gif) |

I knew you guys would pick on my nuts (IMG:style_emoticons/default/ph34r.gif)
Im not sure what lug nuts they are, but I get 18mm grip,which is plenty, flush would look better though. Actually that type fan isnt that inefficient. Looks a lil bit like the fans on the -4 engines? I think these fell out of favor as brake technology became better. I havent seen these for 15in wheels, you could make them or check out swap meets. The 914 gets enough attention at track events here, having these on it makes it even more different (IMG:style_emoticons/default/beer.gif) |
