My car got hammered in at least one test drive - me. I didn't know it would be the only SWP on the lot that day

I am a subscriber to hard break ins. My car is also boosted at 10-12 PSI and has been for 30K miles. It has zero issues. None. Doesn't burn oil. No weirdness in the oil. No loss in compression. Not a single itsy bitsy problem and I am at 62K 10 months in.
So - it's not a big deal. Now - doing drops and shenanigans like that CAN be an issue. But, just properly warming up the car and revving it high and driving it like you would normally? Not an issue IMO.
