Well unfortunately this is not about a Bonneville, but a pontiac none the less. I just spent the day racing with my friend at a solo event ( parking lot course). I can tell you one thing , he has a 2001 Grand Am gt and it kicked ***. He managed to beat a bmw 325, a couple of eagle talon'* that were turbo, some acuras, and other various makes. Nothing like pontiac power to show that you don't need an piece of rice to get things done. And the funny thing about it is that some of these cars even had r-tires ( racing ), and he had factory rubber.
Like I said it'* not about a Bonneville but thought I'd share it anyhow.
