I am trying to determine why there is a substantial difference in lap records at Road America between the Pro and Club FA cars. In 2005 Tonis recorded a new Pro lap record at a 2:01.7 in a Swift 014a. In 2007 Keith Grant recorded a new Club lap record during the June Sprints at a 2:03.1 and Tonis's best lap for the 07 June Sprints event was a 2:03.3, Both drivers were in a Swift 014a. Correct me if I am wrong but doesn't the Club motor make about 20 more HP than the 2005 Pro Spec motor?
What are the main reasons the club 014a is still slower than the pro spec car 014a of 2005?
Inquiring minds want to know
- Level of Preperation and team knowledge of the 014a
- Level of competition that would take the same driver to a different level
- Tires (pro vs club)
- Grip levels during a Cart weekend
