looking at your dyno sheet,your water temp was in the 138 to 145 range,any particular reason for these water temps vs. running the water temp at 180 degrees,more closely to the "normal" operating water temp.???
Just curious.....

I normally run the pulls at around 160 water and oil. Its really a habit from the EMC rulebook, where the 160s are the required minimums and I set the thermostat on the cooling tower to that level. The water cools pretty fast when the engine's off - I have 1500 gallons in a vertical tank behind the back wall. Normally I'll run it for a while under moderate loads to build temp. On this particular pull I was re-lighting it after checking valve adjustments & plugs and realized that I was getting darn low on gas - so I just smacked it as soon as I felt comfortable enough. I happened to have it nearby to scan 'cuz it was the last one of the evening...

Brett can confirm seeing some Hollywood numbers on some sites where water was at 110 or less...
