'Seems you could turn up the pump and cool down the engine nicely,

'especially on the track. That is "if the temp drop is based solely on

'capacity and pressure variables".



I been running their WP336 pump since July, but I made my own adapter plate.
There is a small discussion going on the RX-7 forum currently.  Some pictures of
my setup as also uploaded to the forum.

My winter project is to build a PMW controller for the fans which will also
switch the pump on and off and keep both the pump and fans running when the car
is shut-off hot (until a preset temp).  I have the circuit designed and the
IC's, but need to find time to solder up the board.
