backfire is cause by incomplete fuel burning while coming out of the exhaust, any car that doesn't have a catalytic converter can back fire. sports cars are often tuned to run rich to reduce detonation so more fuel is likely to escape unburned through the exhaust causing backfire.
but it looks like the car in the video has a flame thrower kit, its not backfire.作者: 鸡__蛋 时间: 2012-6-12 10:40:11
