Hi Paul!

      Here's a couple pics of the acrylic damper assem mockup.
   Presently,   the  original 6.9" diameter for the damper section
   looks to be a  little too  small when using the 1/2x1x7/8 blocks,
 as   there is  conflict with the large  washer ring. The image shows
 the blocks    standing on their 7/8 side, instead  of the one inch
 side, and it's    still a bit too large.

      What do you suggest is the next step?

      Ed Carver

      Looking good Ed.

      The shaft project has run into a snag. I need to get the
   material back.    Michael that owns all those big lathes was
 forced   to get a full  time  job to pay the bills. He just was not
getting
   enough biz to  keep the  doors open. I'll see if I can get in
 touch   with him  tomorrow after  his work. I may be able to cut
 them to   length with a  carbide chop  saw I have. Jim thinks he can
 do it   with his lathe.  Just not as fast  as Michael.

      As to the flex plate what rubber blocks are you using?
      I assumed we would use custom molded rubber blocks to fit.

      At least that is what I said in an old message in Sept.

      lots of snips....

      "Now it is possible to design the concave rubber blocks with enough
      expansion
      clearance so no axial force will be generated."

      ------------------------------******----------------------

      OK I think I have it figured out. What you are saying is the 1"
   by  .5"  rectangular tubing  is too big to fit the 6.9 inch diameter
   and  the stock steel clamp ring.

      I probably made a mistake on measuring the clamp ring diameter.
    What  number do you  have on that?

      We can do one of two things. Cut down the clamp ring plate in a
    lathe or  go up on the 6.9" dimension  slightly. What do you think?

      Paul Lamar

    It's why we made a mockup. The ring diameter is odd in that it
    extends outward past the bolt centers more than it does inward.
    Seems natural move the diameter out at least .200". The ring is
    5.115" OD.

    Is there in the plans something to contain the rubber on the inside
    diameter of the .5x1" blocks? The spline plate inward extension
   will  ride about .100" off of the e shaft.

    The spline plate as shown in my photo does not have the OD cut down
    to your spec. That is because I am not sure if I will use it. I
 am    going to use a longer input shaft, and hence, a different
 spline plate.

    Gotta do what you gotta do Michael. I'd be in the same boat if it
    were not for the mass of old porsches and parts I collected over
   the  past 25 years. Even with the bust of the Euro, Germans still
   want  their lawn mower engine powered old 911's back. (I will always
   tease  porsche lovers because they whine too much when they lose
 at the    track) ;)

    A chop saw will easily cut the alum shaft material. I may be able
   to  get the shaft bored in the EAA hanger. We have a couple lathes
   in  there, but they are on the small side and I would need to create
   some sort of bearings to hold the shaft at it's longest extension
   out from the chuck.

      Perhaps Michael can do it as a side job. Can 4.5" material fit
    into the bore of that chuck? The easy part for him would have
 been    turning the housing, which has a much larger diameter. That
 part is    probably out of my size range because it it too long for
 my mill.

    Ed Carver

    To cut it down to fit it must be 4.750" dia..

    What we have going for us is the large 4130 plate is .096 thick
    while the mild steel stock plate is .062" thick.

    I'll try to have another talk with Michael today.

    Here is flex plate rev 4 with with a 7.586 diameter.

    We measures Jim's chuck and we can get 4 inches in there no problem.

    Things are getting hectic around here so after Christmas is going
   to  be it.

    We have a pack of relatives staying with us.

   Ed,

    If you want to have fun with the Porch guys, stuff a GM LS3 into
 a   Beemer3. Use the T56 trans from the Firebird/Camaro and the diff
  from a Beemer V12 car. With a bit of port work, a cam change and
 tune it is 525HP at the rear wheels. Scare the hell out of the Porch
  and blower Mustang guys.

   Dale Davies

   How about a 690 HP p-port 4 rotor?

   Paul Lamar

   Yup, that would do it all right. The Government Motors engine
 might be a  bit  more torquey though for street operation. How would
 the four rotor engine  length be compared to the LS3? No problem
 installing in the Beemer as you  remove the I6. They tell me the LS
 takes 50 pounds off the front end as it  is  all aluminum and
 shorter than the I6 engine that has a cast Fe block, so it  actually
 handles better.

  Dale Davies

  It is about the same as LS1.

  Max torque is 442 ft pounds at 6200 RPM. Do you want to tow or do you
  want to go? :)

  Paul Lamar

 Well Dale, I have a llittle bigger aspirations, than that government
 engine. And as far as the T56 goes, that's old school now. I just
 sold the viper version i had. I wanna PDK 7DT doppelkupplung, based
 on the original twin clutch used in the 962C. Should be able to get
 one soon from a crashed panamera. It'z amazing how some monied folks
 love to crash their porsche. Just another fact of the civilized world.

 4 rotors are too much, gotta make em think they can actually beat
 ya; so a built 3 rotor turbo should be sufficient when coupled with
 a 7DT in the back seat of a 2200lb 914 porsche. And BMW?
 BringMoneyWith, cause you're gonna need it when you lose.;)

 I now consider myself a reformed engine enthusiast. Thanks to Paul,
 and the rest of y'all. So long to the ford/chevy controversy. Never
 owned a government car in my life. As long as we throw the bumdeal
 president out of office next Nov., we should all be able to expand
 developing these rotary things out to their true potential.

 Governmental tyranny will soon be extinct.
 Light the candles again!
 Happy Hanukkah!

 Ed Carver

 I am beginning to really like Ed :)

 How is the length of the 20B compared to the original boxer 4? Might be a
bit
tight. A little grease on a shoe horn has been used before :-)). Even a 13B
turbo p-port would be a rocket. 914 6 would take the 20B no problem due to
a
longer back for the Porsche lawn mower.
 Used Beemer 3's are reasonable in price. One fellow in Calgary has a
fordor
that beats blower Mustangs regularly. They go to the Porch track days and
lap
faster.

Dale Davies


You should visit the porcha club endurance events at night at Willow
springs in May, just so you can see the fire come out of the exhaust on the
old turbo 911s that use the original K-Jetronic injection. Talk about money
to burn. Guarantee ya, there would be no era correct stock bodied 3 series
bimers puttn a pass on a built up 944/968 turbo going around turn 8.

Its all in fun though ya know. Tons of money, club racing at it's best.
