That is interesting. I'm just waiting to see if any of these improvements make it's way into the ZL1 before it's gone forever.

Since the 2.65 L Escalade blower LT4 only makes 14 more hp than the CT5V BW LT4 and similar torque, I'm guessing they used the larger blower not necessarily for extra power, but for the tow capacity rating. The larger blower will have better intercooling of the charge air for those long WOT runs up hill towing a boat, RV, or whatever else people in $150k Escalades may tow.
Towing at capacity in a truck/SUV may require WOT for several minutes (or more) at a time, and the smaller intercoolers in the 1.74 L Eaton likely don't have the capacity for that to maintain reasonable charge air temps, thus, the larger blower w/ larger intercoolers. As far as the intercoolers on the LT4: I've long theorized that the intercooling is slightly inadequate in the 1.74 L Eaton supercharger even in a stock LT4 for long WOT runs (>13 or 14 seconds). It works OK on a track because WOT is intermittent so they can keep up with an on boost/off boost duty cycle, as well as at a drag strip where it will be off throttle within about 12 seconds or so, or less. Obviously, with a 2.65 L blower the LT4 could make quite a bit more power.
