I'm not so good at searches, but after looking for quite awhile I didn't find an answer.
I'm trying to get a feel for how hard I'm stressing my motor, and how much longer I should tempt fate. So, I would like to know who has beaten their stock 2015-2018 Voodoo, and how hard, and for how long, with no major failures and ... obviously ... who's had a less fortunate outcome.
I have 61,100 miles on my 2017 GT350R, which I took delivery of in July 2017. Most of those miles have been cruising highway miles, with the balance in-town. Except for a Ford Performance passenger side oil separator, Caliperfection front caliper studs, and with the factory wheels used only for track days, the car is bone stock. I change oil religiously before 5,000 miles. I have, in the past, occasionally mixed a tank of roughly E30. We now have Sunoco 94 here in the Dallas area.
I've tracked the car on three separate days: March of 2020 at 35,000 mi (COTA); July 2023 at 53,000 mi (Eagles Canyon Raceway); March 2025 at 61,000 (COTA). March 2020 was cool and humid. July 2023 was brutally hot, 104 degrees. March 2025 was 80 and dry. I always prep the car, especially the brakes (been tracking my cars since the late '70s), and I always run race gas at the track (101 octane). [Try not to hijack the thread on the race gas issue; I have plenty of experience with my cars, a number of years as an engineer, and have discussed this with Ford Performance. I have my reasons, and my track experience has proven them out. If you want me to explain, I'll be glad to elsewhere.]
BUT: I beat the absolute snot out of the car at the track. Sometimes I shift at say 7800, and sometimes right at 8250, and sometimes much lower when I don't need the ponies, all depending on various circumstances. And though I'm not one to ride the limiter, I have bounced the car off the limiter from time to time. And there are always some sectors where I might sit at 8,000 for a few seconds (i.e., the essess at COTA). But all in all I have to say I don't really take it easy on the motor at the track. This is by far the highest revving engine I've run and, hey, this is what the car was made to do. Like my wife says, "do it while you still can." But it screams so high that I can't help but think it will someday take revenge on me.
I remember some sad tales in years past where Gen1 Voodoo's failed at the track. I'm not expecting any definitive load cycles to failure data, just collective experience and any informed words to the wise.
Many thanks.
