[V8Vairs] cooling

check out these 18" fans, they pull a lot of air. Wire size is important!

My  16" shrouded electric fan doesn't have a footprint big enough to cover  
 
the entire backside of the 31"wide 19" tall radiator, but still pulls  
enought  air thru to cool nicely.  Checking for full voltage at  the fan 
(as  
mentioned by others) is important too.  AND, I  found I had initially wired 
 to 
the wrong wire on my electric fan (it  was the slower speed). 

I changed my exit air from the fender wells to  the bottom of the trunk, 
and 
put a Camero front spoiler on to help force  air in.  I was on the road  
racing track last April when the  fuse blew on my electric fan.  And at  
speed 
I had plenty of air  to keep the water temp at 190 degrees even without the 
 
fan.   Shrouding on the front of the radiator (to force all the air thru 
the   
radiator) is important too.

Having enough timing advance helps (but  not TOO much our you will have  
detonation).  Higher octane fuel  helps too.

Water wetter helps (but is more effective in lowering  temperature if run  
with straight water than if run with an  antifreeze/water mix).

I am running antifreeze/water mix, and I am able  to have a temp of 170  
degrees (and I fought cooling problems for a  long time, ultimatly finding 
that  
corrosion from the engine water  jacket had plugged up my then new aluminum 
 
radiator).  Figuring  out what is the problem with any particular setup can 
 
be a real  bugger, but keep after it; you can solve the  problem.

Engine   compartment heat is not  a cooling problem...  only has to do   
with 
your comfort....




Airflow  thru the  radiator  is the killer!   Underside of the LM  is a 
high  
pressure  area!    It has to be forced!
