The issue here is heat.  Although a k24 may be able to put out the same
amound of boost, it would do so less effeciently and heat the charge more.
More heat=less dense, and I suppose more likely to pre-ignite.

Additionally, SJ suggests that the K24 housing gets real hot at high boost
and transfers a lot of heat to the charge.

Still, for combined street/track use, I love my K24.
