My G-Tech Times

The following times are made with a G-tech pro performance meter. They are on the same track, same g-tech and same driver and verified with multiple runs. I live in the mountains at 4500 feet in elevation therefore times are slower for n/a cars. The GTP has a supercharger and runs very close to sea level times at this elevation. See the sea level corrected times below for comparison to other cars. (g-tech mph is actual, not trap speed from a dragstrip)
