I'll just leave this here, Duke. I know you're reading this in your wooden shoes and shit.
On Top Gear you see flames come out of an exhaust, usually on Ferraris and Lambos when they take them around the track. Is that misfire...backfire? Or is it simply unused fuel being burned on the next ignition cycle of the pistons? Or is it all the same thing?
And is it necessarily bad that it happens? And do you need a race exhaust (or something equally as unrestrictive and free-flowing) in order for this to happen?
You hear the stutter at about 12-14 seconds? That was only at about 4500 RPM. Why??!
