a street car driven like a street car, i wouldnt hammer it for long periods of time till you had about 5k on the engine at least, but still hit the redline time to time after about 500 miles, its what i did with my last engine, now i hit the fuel cut 1-2 times a day and drive it hard cold, i think there is about 60k on my current engine and ive beaten it for about 50k every day like that
i do compression checks before and after oil changes and i get about the same results depending on humidity and outside temps, no metal filings yet
