Numbers look good but they are on race gas. That car is a train wreck, it has been on fire, and alrady had its engine and transmission rebuilt/reinforced. Hell, I would not be surprised if numbers are fake for YouTube views.
But I gotta hand it to her, Amelia has gone where nobody has taken their C8 before. Hell, I don't even think anyone in Canada is coming close to doing the twin turbo stuff that she's doing.
What you see is exactly what you get with Emelia, there is no BS involved. IMO she is the most down to earth YouTuber out there and the numbers are certainly possible with the amount of mods that has been done to that engine.
