Very true.  Will the "right" cooling system please stand up!

My cooling system is too small for the power I wanted to be able to use.  I
could still outrun any 160 hp RV-6 and outperform those with 180 hp and
fixed pitch props.

But I was out-climbed by the guys with 180hp and c/s props and outrun by th=
e
200 h.p. crowd.

This should have been good enough.  Flying n.a. there were no cooling issue=
s
at all.

But I am starting to think that cooling is like money.  No matter how much
you have, its never quite enough.

My current plan it to go from a 2" rad to a 3" rad of the same or
larger surface area.  I will also add some fresh intake ducting, a cowl
flap, and spray system.

That should allow me to easily beat the 200h.p. guys....  but then there is
always the tri-aviathon...

Any suggestions?  :-)
