Sorry, but I was correct. Springfield is just over a mile in length. 1.03 miles in length. Lap Time was 24.710, which is 150.061 MPH, on June 7th of 1998. The last WoO show, ever on a mile plus,track!
You are right in the fact of 170-180 MPH on the straightaways. Champ Cars are doing close to 160 at DuQuoin, on a GoPro with MPH on.

I don't post things, like World Records, unless I know my facts. Especially when it's about one of my All-time favorite drivers.

Thanks.
