IMHO this is the most successful 13B cooling arrangement so far flown.
The rad is a custom double pass 533 cubic inches by two inches thick.
The rad fits in a stock RV6 cowling. Note there is no
room under the PSRU for a starter with the rad in this position.

The throttle body and K&N filter is under the intake plenum.
The stock Mazda ignition coils are back and down from the filter.
The remote oil filter is down in there too.

Congrats Chuck on a beautiful installation.

Paul, have you got a picture of Chuck's cowl?

One of the things I forgot to do. Stock RV6 cowl with a chin intake for the
rad. The left cheek intake is used for oil cooling and the right is open
for engine intake air.
