HI-performance?

Post by joe porsche » Tue Mar 25, 2003 1:44 am

this sounds like just what Ive been looking for......the wevo xt 915 tranny ... this thing sounds like its the best you could get.the best shifting at only 2 inches from nuetral.they claim shifting can be 4 times faster than the stock 915 tranny. dont know how to bring up the sight so its www.wevo.com I wonder how bad this thing would make my wallet scream.........

Your wallet would scream very loudly. You'd have to buy a 915 tranny ($$$), get it converted to spin the other way ($$$), buy or fabricate mounts ($$$), either convert to a 911 electric speedo with associated wiring or adapt a mechanical speedo sender onto the 915 tranny ($$$, unless some 915s used a cable-operated speedo??), work out the clutch issues ($$$!!), and then buy the Wevo shifter setup ($$$).

Wevo is working on something for the 901 transmission that the 914's tranny is based on. You might wait for that and see if it will work for 914s. If it works for us like the 915 version does for the 911 guys, it might just be worth making your wallet scream...

Frankly, there isn't anything currently on the market that is a significant improvement over a side-shift linkage in good working order. If you get all new bushings, and do the work that is needed to make sure that everything is in tip-top condition, the shifting will actually be pretty decent.

Most of the extra work involves the "castellated" bushing in the side-shifter console. It often moves around in its hole in the flange, and the rear shift rod is often a loose fit in it. There are various things that can be done to the shift rod, the bushing, and the flange. The idea is to have the rod slide smoothly but with zero slop in the bushing, and to have the bushing stay put in the flange.

There are cable-shift setups available, but some talk with people who have them indicates that they aren't a real improvement. And they're pretty expensive. Their main use seems to be to allow the 915 transmission to be used somewhat more easily. But some re-work of the cable setup is evidently still needed.

If you have a tail-shift transmission (70-72, some very very early 73) then consider a swap to the later side-shift setup. If you have a side-shifter already, go through the whole linkage and make sure it's all nice and tight.

After that, all you can do is wait for the Wevo guys to finish up their 901/914 setup. Or fabricate something yourself.

I have to say that just replacing all the bushings made a complete difference on my 74.

Don't forget the ones in the rod itself-- I replaced mine "on principle" ( I thought they were fine---They were actually powder inside) and jb-welding the rear one in place (tranny hole was VERY sloppy)

Actually shifts nice now, period.(Not just for a 914)

Still has room for some slight improvement--looking for thinwall polyamid tubing for the rear to go over the rod.
(turn down, glue on is what I'm thinking)

Piledriver...are you looking for this tubing to use as an antifricton bushing? What wall thickness do you want to end up with? If you just need a very slick, built up surface, try eteched Teflon. It is teflon sheet that comes in various thickness, and has one side chemically etched to accept the adhesive of your choice. Very slick, very cheap. Come in thickness from about .008-,035" Ray

Sounds good, but I worry that Teflon might not have the mechanical toughness required.

Same idea. but polyamid--- think kapton tape. 10x the wear of teflon (or more) and some flavors are 100x slipperier. (is that a word?)

Ah. You are looking for impact resistance as well. Yes, teflon is soft. I do have some torlon rod, but it may not be big enough in diameter. I know where to get it in Dallas. They have lots of odds and ends left over from other orders. Torlon is awesome. 600+ dgerees...slickerer ( nice word huh?) than teflon by far. Highest impact resistance of them all. Let me know if you want some to play with. Ray

You can use the Wevo with a 901. You will need a 915 shifter base ( $190.00) then send it to wevo and they will machine it for the 901 gearbox.

How about a Five speed from a VW Fox, or Audi 4000?

I'm not sure either of those would hold up any better than a 914 trans.

I saw the Wevo setup at the SSI swap meet this weekend. Man what a sweet setup!!! cost some money but will really do the job.
