Steve,

Little has been done with the test stand turbo Renesis in the last almost t=
wo years.  I had satisfied myself that the Renesis with the turbo installat=
ion was reliable and plan to install it in my RV6A.  Before removing the NA=
 13B, I have been trying to address several concerns. =20

First is to achieve an excess of cooling capacity in the present installati=
on in anticipation of the added cooling requirement expected with the turbo=
 Renesis.  This is still ongoing.

The second concern is the input shaft of the RD1A.  Even though I plan to j=
ust turbo normalize, I would like to change the rosette weld to the pin of =
the later RD's.

Third, the flex plate should probably be eliminated and replaced with a fly=
wheel, also eliminating the damper plate with its aluminum rivets.   Appare=
ntly this is also a feature of the later RD's.

Finally, the turbo exhaust has a three inch diameter outlet which immediate=
ly transitions to a two inch tailpipe.  This transition appears to result i=
n significant back pressure at the turbine outlet.  A three inch diameter e=
xhaust system from the turbine outlet onward will be installed and tested.

Things always take longer than expected.

Hi there Steve Boese

Can you give us an update on your Renesis turbo test stand setup?
What have you learnt? What are your plans?

Would be appreciated
