I ended up using double V-belt pulleys off an '89 13B for the eccentric and water pump, and then used Canton Racing's single V pulleys on each of my dual ND alternators. =20 If you need a large (4") multi-V pulley for an ND alternator, I have a couple that I no longer need after performing the change described above. They are modified Honda power steering pulleys. The modification consisted of removing the splines from the center hole so that it will slide over the alternator's armature shaft. This was done on a lathe, so the hole is still concentric.

I remembered last time I talked to Bruce Turrentine , he =20 said that I should replace the stock Cosmo pump with one from another =20 model engine, but I can not remember which? You 3 rotor guys may know =20 which pump he was talking about? Another thing: I still have the original serpentine belt pulleys and =20 wander if it is a good idea to switch to a double V-belt setup. And source for all the pulleys. Looks like my single serpentine belt =20 was slipping at high RPM Buly http://tinyurl.com/dcy36 -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net/lists/flyrotary/
