Vendors just love it when people don't ask discretely back channel (where's
the sarcasm smiley?)
Its a work in progress. Finished up to the point of everything on the hot
side. As we said earlier it will be a complete solution, not something that is
going to leave you with having to figure out the other half on your own. In our
case this has meant effective implementation and mounting of the alternator(s).
We are also using the renesis water pump which adds several new wrinkles to the
mix.
-even with underdrive e-shaft pulleys you will be considerably overdiving
any automotive alternator in cruise. Our calculations worked out the need for a
4" diameter alternator pulley(s), confirming Mark's choice. Unfortunately Mark's
chosen vendor has discontinued the pulley. We were not able to find another
vendor making a 4"OD/15mm ID so we had our preferred vendor (us) make them since
we needed 2 for our engine, 2 for the spare and 2 for the show mockup.
-The Samarai alternator fits on the renesis mounting boss but the pivot
bolt is smaller, Rather than drill out the alternator the boss should get bushed
out with stainless bushings. This aligns the alternator with the water pump. The
alternator is flopped over to the cold side, this improves the wrap of the belt
and lowers the top profile.
-the renesis alternator/WP combination does not align with e-shaft pulley
by something less than an inch. We are machining a spacer to move the whole WP
assy out the needed distance and all pulleys will be aligned. We have a few
renesis front covers to work out the CNC tool path for separating the WP housing
from the front cover. Its sort of a hairy job to do with a large bandsaw and a
couple of hours with a die grinder to clean them up. If you have renesis front
covers available we would be interested in buying them to use as cores.
-This will determine the placement of the second alternator over on the
cold side running off of the forward e-shaft pulley. Then we can machine the new
side mount for the second alternator. The mount will be available in two
configurations, one for a single alternator installation using the eshaft pulley
closest to the front cover and in this dual alternator configuration using the
other pulley.
-finally this will determine what room is left for the plenum and throttle
body on the cold side. Convoluted getting there huh?
-availability. Going to make it a priority over the winter to make some,
also have the gasket for a 20B to work out the flange for it.
-Beta testers; ever notice they don't call them Crash Test Dummies in
aviation?

I posted this publicly to try to get their egos going. =D I
was in the

saying
"wow, I really don't want to finish this now that I've seen what
