YES, a centri isn't getting any cooling effect when not moving, but it's also not generating any real heat like a PD. Granted that the centri isn't cooling anything in the lanes, but neither is the PD. Fluid is circulating, but there's no air movement across the heat exchanger, so the fluid just gets hotter and hotter (heat soak). Heat soak is going to be much more prominent on a PD car than a centri. At least on the centri it starts cooling as you go down the track and you're essentially starting with ambient. On a PD, you're circulating hot ass water as you go down the track! LOL! I've had both and I think a PD makes a LOT more heat, both on the street and the track.
Edit: Obviously, a PD with an A/W with fans, huge reservoir, bag of ice, etc. will cool better, but that's not what ANY of them come with from the manufacturers, so that's a moot point. I'm talking about how they come in the kits.
