Testing out my Olympus ME-51S external stereo mic with wind muff, mounted in the engine bay of my Time Attack / Autocross Mazda RX-8. It is mounted near the passenger firewall, near the windshield washer fluid reservoir. It does an excellent job picking up the sound of "spinning doritos revving to the moon" (courtesy PCA autocross announcer).
Unfortunately, i was trying out a different shifter for this event and on both of my flying laps i mis-shifted from 4th to 6th gear on the straight, costing me quite a few tenths i imagine. Otherwise, i was pretty close to lap record pace. Going to swap back to OEM shifter for the next event...
Back in 2021, i ran a 1:39.6, and predicted to beat a 1:38.7 (the T4 lap record) the next season:
• SCCA Time Trials | #51...
For 2022, i added an STX-legal cold air intake, pulleys, Racing Beat springs, big front swaybar, and a max-camber front alignment and was able to get to a 1:38.9 with mis-shift, so i definitely was on pace to beat the old T4 lap record.
And yes, these are the same Kumho V730s that went on at the start of 2021 for a full autocross season and a busy track season. Still at about half tread. Still have decent speed. But still costing me probably 1.0+ seconds at the circuit versus A052 or RT660...
