Anyone have experience at Mid Ohio?
We plan to run our SR3 RS 1500 there in a couple of weeks, and I was wondering what we should run for a gear ratio in the GDU.
Looking at my data, with the 3.07's at Road America we were doing 135 at roughly 10,250rpm. According to the chart, 3.07's should be good for 145.49 at 10,500rpm. Don't think the extra 250rpm is going gain another 10mph. Anyone have data on what the 3.07's will actually do at 10,500rpm?
How many actually run to 10500 or do most short shift?
