I'm 828 miles in on mine. I've heard the raspy metal on start up a time or two.
But - the noise that I have at 1800-2k RPMs under slight throttle sounds exactly like the "piston slap" of the Coyote Gen 2/ Voodoo Gen 1. I am less than a fan. I've not tried it in park revved to 2k yet. I'll test...
I'm enjoying seeing all of these updates! I just got an estimated arrival date of 8/31-9/6.
Not sure what the original order date was as the Husband ordered it for my birthday gift, but Order Confirmed on 4/11, went into production on 8/3.
My birthday is 9/9, so fingers crossed!
