The above statistics clearly show that weather does make a difference in the
performance of blown engines. We will continue to evaluate performances and make
changes as needed. Changes will be made carefully and reasonable time will be
allowed for testing. No changes will be made for the Amalie Summer Nationals.
However, statistics from Cordova will be compiled and evaluated. Adjustments to
keep the Nitrous and Blown motors equal and competitive will be made as necessary.
