Driving Again & Performance Test

I drove the Mustang around tonight to make sure the rattle sound from the rear hubcap was fixed. The sound does seem to be fixed which is good.

I drove around the neighborhood some and then drove on the highway. What I thought was road noise must have been the rear wheel bearing as it is much quieter at highway speeds.

I had the new G-Timer in the Mustang so I decided I would try a quick 1/4 mile run. I spun my tire (no posi) quite a bit when I took off. I shifted at 4,500 RPM. The timer is suppose to flash when it completes a 1/4 mile. I hit 90 and then started to slow down and after slowing down, it flashed and said my top speed was 80. Not sure why that would be but these are the numbers it recorded:
1/4 Speed - 80.4 MPH
1/4 Time - 17.00 Sec

1/8 Speed - 65.6 MPH
1/8 Time - 10.9 Sec

60' - 2.63 Sec
0-60 - 8.93 Sec

I'll try again another time before replacing the carb. I think the wheel spin likely impacted my time. I'm not sure the carb will help much without rear gears to keep the RPM high but we will see.
