Poor MINI.
Rebrn has all the gory destroyed engine photos and this calculation:
Using the numbers for an 02 mini Cooper S:
First gear = 4.167:1
Final drive = 2.74:1
Tire diameter d = 20.62 in
Circumference c = pi *d = 64.80 in
70 mph to in/min
70 miles * 5280 ft/mile * 12 in/ft = 4435200 in
1 hour * 60 min/hour = 60 min
4435200 in/60 min = 73920 in/min
Now, 73920 in/min * 1 rev/64.80 in = 1141 rpm wheel speed
1141 rpm * 2.74 * 4.167 = 13025 RPM engine speed, not accounting for any clutch slippage.
Diagnosis: FUBAR
Poor little guy. Probably kept up for a mile or so.
