BMW spent millions developing the E46 M3. I threw a slightly bigger, tuned engine into a 34-year-old shopping car. As a result, when racing said M3 though a series of roundabouts, all my coolant fell out.
Turns out the thermostat housing is warped from, I’m guessing, attempts to weld it, so it blew the gasket at about 7000rpm in 3rd. It sprayed coolant all over the screen and left a pretty impressive trail of steam behind me; the main point is I only lost a car length on him before slinking off down a side road to boil in shame…so technically I won*
*I did not win.
