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 was in the
hangar today looking at my intake, just under half done,
and saying
"wow, I really don't want to finish this now that I've seen
what the
Girrrls have coming..."
