I actually fly out of Indy on Wednesday to go down to Daytona for the 500... so I will try and post some pics for all those that don't get to experience Cup racing the American way. haha!
I do find rally racing very intriguing though. Racing is actually how I got into engineering... My brother races sprint cars (also a blast to watch) and my dad is a car owner and crew chief for him... but I never got into racing as much as the technical side of how the cars work and so on... So I love watching those WRC cars and how well engineered they are... But true marvels of engineering are the Japanes GT series cars... those things are nuts!
If you like dirt racing check out the World of Outlaws... whipping around a quarter mile DIRT track in 12 seconds is pretty F'n crazy... those cars are the exact opposite of engineering marvels. They're just American Muscle... 900 hp with a direct drive shaft... and one gear... GO FAST!
