Default Hmmm.

Someone just emailed me and told me my math was wrong.

7033rpm in 4th gear, with a 3.50 rear gear yields 2009rpm at the rear tires.
If the tire diameter is 27", that's a 7ft circumference.
2009rpm * 7 = 14063 ft per minute or 159.8 MPH.
Hmmm, wonder if my tire diameter number is wrong.
But even if it was 26", that's 2009*6.8 = 13661 ft/min or 155mph.

My guess is 140 is what the g-tech said...and the difference is tire slip.

In any event, she's zippy.
