Every time I have ever seen a aftercooler upgrade for the Vortech supercharger they have come with a smaller pulley for the supercharger to make more boost to take advantage of the much cooler air charge. I have not seen any detonation issues on pump (92-93) gas with Vortech's kit. They seem to work extremly well.
