On a sidenote I just figured I'd add that it's amazing how prone these set ups are to heatsoak on the full stock sealed LTR set up. An external reservoir is an absolute MUST. After five dyno runs my temps stayed pretty stable and my horsepower losses were within 10 HP on all of the runs. I'm tuned, so that does come into play, due to calibration limitations within the factory flash file, but still.
No real cooling mods either.. just some water wetter and an LS3 thermostat 3 degrees cooler than factory setting.
