Hi Paul,

                  Thanks a lot for that info, it sure helps. Hey if you ever decide to come on down to NZ, let me know, I have a hangar here at Tauranga Airport with accommodation built in (spare room) transport etc.
If you wait till I’ve got my Long EZ flying I can even fly you round the country, the scenery here is awesome (especially from the air).

                                  Cheers Chris.



Thanks. The same goes for us. We have an apartment above the hangar and if you come to SZP in CA you can stay there for awhile :)

Can you get Ford truck auto trannies in NZ?

Hi Paul,
         I haven't looked yet, I'm sure they will be available but they will probably be a ridiculous price here. Where do you suggest, E Bay ?

Good deal $154 US

Better yet $30 US.


Make sure it is the six pinion version.

Do you use a 3D program? I can send you a bunch of DWGs IGS on all this.



As I recall you have NC tools.

The best way to attach the sun gear to the input shaft is the same way I
did it on the turbo compound coupling. Much better than one or two pins
that go all the way trough the shaft and sun gear. That weakens the
shaft. Tracy did it that way and it failed in one of the higher power
engines. It is easy to get eight pins on any coupling. Eight times
stronger than one long pin of course :)

This is the same way you fix the ring gear to the housing.

It is much much lower cost than a spline and will fit all diameters.
IMHO a major
development in couplings of all kinds.

Also, if you drill holes in the heads, you can safety wire the heads
together to make sure they don't back out.  Locktite helps as well.

Hi Paul,
   Thanks for sending that info and the links to ebay, however they are for the rear set and I am going to use the 2.85 ratio (front set). I couldn't find any on ebay (maybe looked in wrong place). What gear box are they out of by the way ?
Those drawings would be helpful if you could send some that would be great. Haven't found anything here yet but still looking.
       Cheers Chris.


The rear set are more robust and they yield 3.17:1 which gives you more P-port  power.
8300 RPM instead of 7500 RPM and about 275 HP instead of about 250 HP.

Still not up to the 9000 RPM red line of the stock RX8 engine.

Your intake runners will be about 16 inches plus or minus 2 instead of 18 inches
plus or minus 2.

The high altitude cruise will be spectacular.

Put 20 gallon "bomb" tanks under each wing and you can make Sydney.

Long EZ's float if God forbid something goes wrong :)
