Without a water pump you are asking for detonation from hot spots and
localized over heating., steam pockets and a whole bunch of other nasty
things. If you refuse to run a real water pump at least precharge the
cooling system to 20 psi with air so you have some hope of getting down
the track for more than a mile at a time. I can pee as hard as most of
the electric water pumps and they do little to pressurize the engine.

Hi Sparky
Great you fired the big rat!
Were the temperatures you quoted with the rat idling or reving with no
load?
Things will probably be a little different under load at full tilt.
I remember when you stopped by you mentioned that my water tank/aluminum
radiator setup held more water than yours and you are making, oh,,,
about twice
the HP I am.
Mine went from 180 to 220 during a short squirt down the Texas mile but
I
don't have any circulating pump like you do in the tank. I'm hoping the
size of
the tank will offset the lack of the pump. Maybe I should install one
just to
be sure. Any thought's out there?
Looking forward to seeing you again.
Otto
