rad and coolant

[Mario Tito]

Ok, so INCREASED flow thru block is bad (danger of cavitation)
Incrased HP creates more heat than oem.
Only choice: increase radiator efficiency.

 Normal flow thru block:
   (this represents coolant passages thru the block)
----------+-----+----+
pump>>>   [ > > [  > [
          [v    [v   [v         Coolant passes equally thru all parts of 
block (utopia).
to rad<<< [ < < [  < [
----------+-----+----+

Increased flow (removed therm. or bigger pump{?})

----------+-----+----+
pump>>>>> [ >>> [ << [
         V[v    [v   [^         Coolant not passing equally, and pulling 
some the wrong way.
to rad<<<<[ <<< [ >> [
----------+-----+----+

Ok, maybe the cavitations make only 'little swirlies', but the idea is 
the same- heated coolant gets caught in its own circular pattern, 
creating hot spots.
Excusing the ascii art, have I everyones' agreement? This does not 
explain the plane 160 deg vs 195 deg therm difference (does it?), tho....
