So far the only vehicle's I've taken to 150K miles were flogged relentlessly that were performance oriented were my 1995 and my 2001 Trans Am's. They both did amazing, engine wise! The diff on t he '01 WS6 did give out ,though, but really, it's a known issue. The transmission was doing alright except for the T/O bearing, which I replaced and noted the clutch had a LOT of life left, at 80K, and reverse's syncro was starting to really suck (a known issue with the T56). The 1995 Trans Am had the transmission destroyed at 120K miles before I bought it, as well as an axle sheared in half (neutral drops, I bet...). It went to 170K miles for me, with just a heater core replacement. Both engines were running strong with very minimal oil consumption, and no smoke. The LS1 burned the same amount from 70K miles when I bought it, to 150K when I sold it. About 1/4 quart per 4K miles. Both ran amazing the day I got rid of them.
Now, the other cars I have experience with, a G20 (SR20DE), I took to 145K miles, and it was fine 100% except the transmission went out a few k after a fluid drain/fill at 115K miles. IT wasn't acceleration induced failures. I flogged it relentlessly, too. Ran great.
Multiple police cars, my Dad and I b eat the [censored] out of them, AFTER the PD's did for 60K miles. We averaged about 220K miles out of the 4.6L mod motors. By then they were using a fair amount of oil where you poured a quart in at every fill-up. Pretty lame. Not a Ford fan.
My 2015 CX5 constantly got t he stick. Everything was flawless to 106K miles when the fuel pump and fpr both died at the same time, 5 minutes after fuelling up...also a diff I flooded during a stream crossing at flood stage. Neither have anything to do with WOT usage.
I guess in short, I have not yet found a problem with going WOT in a vehicle, ESPECIALLY from a roll where the diff,etc. isn't stressed.
Maybe it's after the 200K mile mark that it matters? Oh, well. So much more that can go wrong with a car than the drivetrain to worry about that, specifically.
