I know there are some fairly
reliable overall estimates of the drag of an RV (CAFE reports and others), so if
an reasonably estimate of cooling drag could be calculated then we could sort of
determine how much cooling drag is or is not affecting your overall
performance.
Thanks for the thoughts. I would be interesting to
know just how much is at stake, in order to make better compromise decisions
with regard to cooling. I'd have to know that there was a lot to be
gained in cruise speed before I'd accept marginal climb
cooling. At the moment, I have bigger drag issues that need
to be addressed first, but some of these have to wait for the completion of
Rev-3, to see if I have to reposition the
cowl.
Your radiator cooling capacity would
certainly appear to be more than you need given your low coolant temps (assuming
they are close to the money) with your current set up. But, the 2.85 and
higher rpm producing more power will eat up some of that.
Don't
worry, I'm not doing anything to reduce cooling capacity until I get
the C drive and prop installed and tested. If there's any capacity
left over, there's always rev-4. I have a feeling the new
motorcycle hobby, and depressed market for my RX-7 will keep me from
buying a $2000 supercharger.
Cheers,
