Ya theres no doubt the intercooler has helped dramatically. I also don't notice heat soak like I used to.

Up to. You have up to 90lbs that has to be rotated at a distance of 1' from the center. I say up to because the weight is distributed across that entire distance and is not held entirely at that 1' mark. The weight of the wheel centerpiece needs to be taken into account.

I suppose to calculate it precisely, you'd need to perform some integral calculation to determine the sum of the weights across the span.

A much easier method would be just to do two runs, one with stock wheels, one with the 24s.
