Now here's something you don't see every day.
Sprint Cars don't use a clutch or have starters, so they require a push truck to get them fired up. That's why it's a pretty rare sight to see one on a chassis dyno. This rig at Roush Yates Performance Products has been modified with a monster sized high-torque electric motor that's routed through a gear reduction drive and then spins the rolling drum with a couple of truck tires. There are only a few like this in the entire country, and it's a pretty impressive thing to see.
Even more impressive than that, however, is watching a fire-breathing Sprint Car strapped down and trying its best to get loose. The car in this video is in the smaller displacement 360 cid class, so I can't wait to catch a 410 car on there one day.
This video is a short ad I did for Roush Yates Performance Products, but I thought you might enjoy it too.
