On your Recommendation I spent an hour on the phone yesterday with Carl
Adams... of Adams Pumps..
Carl is a LSR fan... and a Nascar Cooling specialist... it was a fascinating
conversation and I look forward to hanging out with him on the 28th....
He was saying what we needed was a Minimum of 35 gallons of Flow per Minute
and that the Water Must in fact Flow through all the Block.. not just the
Front... Back cylinders are often stagnant.... He was a BIG FAN of
Thermostats.... saying they need to be VERY HIGH.... like 190 or so.... he
wanted the Water Temp to be in the 210 range to Make Power... saying there
was 80hp difference in one of his applications between 160 and 210
degrees...
His other Big Comment was that the Pump needed to be Measured not at the
Pump but through the Block.... at the outlet.... anything else is just
guessing at what the actual flow through the restrictions really is...
I can't remember all the conversation but like you John... I was very
impressed with the guys knowledge of Cooling.
