Looks rather cannon prof.
What is the overall length? Should be kept to 15 inches to fit in most cowls.

Paul Lamar



For a test item it may yield significant data. If it shows promise we can always try
lightening it. The drive itself is just under 13 inches.

Milo

That is a nice sun gear spline. Where did you get it and the mating female part? A bit
overkill for only 300 foot pounds.


Paul Lamar


Paul,

We have enough pieces now to get good measurements, so far no glitches.
Milo

The critical measurement is from the bell housing mounting surface to
the prop flange. If you are using a Mazda bell housing part of the PSRU
must be recessed into the bell housing which I think you are doing.
Is that a Mazda bell housing?

Paul Lamar



Yes it is a Mazda bellhousing, but it is not the one I want to use.
We are still shopping for a RX8 automatic bell housing, if you or
anyone else has one, please lend it to us.

Milo


You should build the box to bolt to Jeff's adapter plate
as that has built in motor mounts. RX8 auto tranny bell housings
are hard to come by and if bought new very very expensive.

   Paul,Milo,
I was under the impressiom that the 93-95 RX7 and the 90+ Cosmo 13B & 20B auto trans
    bell housings are virtually identical to the RX8 auto housings.......

   The 93 to 95 RX7 are even more rare than the RX8.
   Same goes for the 90+ Cosmo.

   The best thing to do is use Jeff plate and forget about a bell houising.
   Sooner or later you are going to need a motor mount. Our universal motor mount is designed
   to be used with Jeff's adapter plate. It is the lowest cost way to go.

Milo,
There appear to be 2 rx8 auto trans bell housings available on car-part.com <http://car-part.com>
