Specs.. Are they legit?
There is a lot of Talk about speed specs. An with Racing aircraft that race reno there can be some real variance. The basic airframes used from a Shoe String to a SnooShoo or old Cassutt 11m often stays the same but different modifications and how hard you run the engine makes changes in top speed. I'm going to present Specs that I feel are honest and represent real world numbers and no hype. Top speeds represent running beyond traditional RPM's Performance is based often on keeping it light and clean.
