Any Metallurgists Care to Explain this Video?
Can anyone explain this to me because I've seen a lot of car videos but never anything like this. American BMW tuner Dinan has bored the 5.0 liter V10 from the previous generation BMW M5 to 5.8 liters. According the video it makes 720hp at 8300rpm. What I do not understand is the exhaust. I've seen glowing exhausts before. It's not that weird. I've never seen an exhaust glow purple before. I assume its the alloy or type of metal used. Could it maybe be titanium?
