In this vivid demonstration of how steel differs from aluminum, we see how a junkyard-turbocharged Mitsubishi V6 eats one of its own pistons.
This Dodge Shadow, which won the coveted Index of Effluency trophy at the ’09 Goin’ For Broken 24 Hours of LeMons race, showed up to the Buttonwillow event with a hooptily installed remote-turbocharger setup (complete with intercooler in the passenger-seat area) force-feeding its Mitsu V6. It worked just fine… for several hours.
Hey, what’s that terrible noise? Better come in for a pit stop!
When the team got the head off, they discovered that the #6 piston was just gone. The rod and wrist pin were still there, but the aluminum piston got vaporized. Hey, maybe it ran a little lean?
The only remnants were some tiny metal particles on the other pistons. Yes, racers, ghettocharging your engine can result in unpleasantness when your kludged fuel-delivery system doesn’t work exactly right.
