I'm pondering how the hell I keep a speedo when I go to a 915 tranny that was setup for electronic speedo? I've seen an article on a 915 conversion for an older 911 and they welded a speedo drive gear to the pinion shaft, but I don't know if this is feasable when using a Wevo tail piece?? Has anybody BTDT??? I guess maybe I'll need to learn to live without a speedo, but it would seem really cheesy to me to have that big non-functioning gauge in my face all the time (IMG:style_emoticons/default/mad.gif)
I've seen a few really nice 3.x sixers with 915s and I imagine someone has figured this out. To run the electronic setup after flipping the R&P I would think I'd have to mod the case side cover for a sensor since the flip puts the emitter on the removable side of the case??? What do the "hotrod" guys do? Is there a aftermarket emitter for the axle or something? They usually have some trick aftermrket setups for street rod stuff. |

If the 915 is the cable-speedo type, then no issues.
If it's the electric-speedo type, then run the wires to the speed sensor and use the speedo from that year 911. The rest is details. Non-trivial details to be sure.... --DD |

Tranny experts keep me honest here, but I believe a 915 with a flipped ring gear will not drive the stock electronic speedo pickup since the magnets that trigger the pickup are on the ring gear, which is now on the *other* side of the case.
I'd still suggest using an electronic speedo instead of recreating the mechanical drive nightmare. Here's how: http://www.914world.com/bbs2/index.php?act...c%20speedo&st=0 |

John........Schweeeet, That's just what I was looking for! I've been lurking on a 911 speedo on evil bay, but wanted to see if it was feasible.
THANKS!! (IMG:style_emoticons/default/pray.gif) |
