FOR IMMEDIATE RELEASE – POWRi NATIONAL MIDGET REV LIMIT CHANGES

FOR IMMEDIATE RELEASE – POWRi NATIONAL MIDGET REV LIMIT CHANGES

Belleville, IL – After reviewing the data provided by on-track results from POWRi Illinois SPEED Week and races up until present day and comparing that data to information from the races earlier in the season, pre-current rev limiter rules, it has become apparent that the rev limit rules must be adjusted.

Effective immediately, POWRi will be going back to the previous rev limits allowed.

Gathered data has shown that with the two major types of engine designs (push rod engines and overhead cam engines), the rev limit rules have impacted the performance and slanted the table against the overhead cam engines. The present rules have not affected the push rod engines as much as the overhead cam engines because the push rod engines’ power curve is broader and comes in at much lower RPM range. On the other hand, the overhead cam engines have a narrower RPM range and work better in the top range.

“We thought this rule was a step in the right direction,” said Kenny Brown, owner of POWRi. “After reviewing the data, we realized it was not. The goal of implementing these rev limit rules was parity, to ultimately save money for car owners with increased time between engine maintenance cycles, and to welcome lower cost alternatives to current engine platforms. But it has become apparent over the last month of racing that the rev limit rules never actually accomplished this. We made a mistake heading in this direction and therefore, POWRi is going back to the previous rev limit rules.”

POWRi will continue to monitor all engine performance and will make necessary changes as needed.
