OT: Flames in the exhasut pipe? Posted by MI-Roger [Email] (#882) [Profile/Gallery] (more from MI-Roger) on Fri, 5 Feb 2016 05:38:45 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Not my car but a general question.
Today was the second morning in the past two weeks that I have followed the same small red coupe the final 3-4 miles to work. Every time the driver shifts while accelerating briskly, I could see a puff of red flames in the muffler of the car. Leisurely acceleration does not produce these visible flames.
Today I got close enough to see the car brand, a Mitsubishi. I thought their performance coupes were turbocharged?
Obviously this car does not have a catalytic converter, and the exhasut system must be a straight through design for this combustion to be occuring in the muffler. I say the combustion is in the muffler as I don't see flames exiting behind the car like the Autorama exhibits, and there is only the short discharge tip attached to the rear of the muffler.
What has this owner done to his/her car to cause this? Running way too rich? A cam shaft with a lot of overlap that discharges unburned fuel/air mixture into the exhaust?
The car's license plate is an acronym for All Wheel Drift so the cause is deliberate rather than shoddy maintenance.
