Practical Streamlining

This is a video about the effects of streamlining released by Chevrolet in 1936. It’s a pretty good primer for a study of aerodynamics. There’s even some good shots of turbulence simulated by water and aluminum powder flowing around objects inside a neat little paddle wheel machine. You can see that the most aerodynamic shape is a teardrop. This was figured out early on by observing a water droplet as it fell through the air. It naturally took the shape with the least amount of drag.

Fredric Aasbo at Formula D Long Beach 2012

Torco Oil posted this video of Fredric “The Norwegian Hammer” Aasbo from Round 1 of the 2012 Formula D Drift Championship at The Streets of Long Beach. He drives the Papadakis Racing / Need for Speed Scion tC. Aasbo took over the ride after Tanner Foust left Formula D to pursue rally and his spot on Top Gear USA.


MotoIQ got an inside look at Fredric’s car as it was being converted from a NASCAR V8 to a turbocharged 4 cylinder engine. They’re currently using a built version of the 2.7 liter engine from the Toyota Sienna minivan. It’s set up with a Borg-Warner turbo with built-in wastegate and blow-ff valve being fed with E85. Head over to MotoIQ to see the rest of the pictures of the engine and suspension.

Basic Rally Techniques with Colin McRae

This is a vintage video of Colin McRae teaching basic rally driving techniques to what appears to be a reporter. As with all master of their art, McRae makes everything look effortless. He’s able to instruct and hold a conversation while flying through a fairly narrow and technical dirt road in the middle of a forest. They cover a lot of basic concepts that will allow you to appreciate what rally racing drivers do if you are not already familiar with the sport.


Let me add one thing to the section on left foot braking. McRae says he likes to use his left foot to hit the brakes because it’s faster than transitioning his right foot from the gas to the brake. Most rally cars are set up with a strong rear brake bias. The reason they do this is because it allows easy drift initiation while braking for a corner. In front and all wheel drive cars, you can be on the throttle with your right foot and drag the brakes with your left foot to slow the rear wheels down more than the fronts. Left foot braking in this case gives the driver a lot of control of the sliding and weight balance of the car. There’s a good shot of Tomi Makinen doing this in the Best Motoring video I posted a while ago.

Lawless Electric Rocket Sets Drag Bike Record

Lawless Rocket Assembly at OCC via gizmag

Lawless Industries of Ohio teamed up with Orange County Choppers to produce this drag racing bike, the Lawless Electric Rocket. Larry “Spiderman” McBride piloted it to a record 6.94 second 201 mph quarter mile run at Virginia Motorsports Park. The Rocket uses a 13 inch DC motor, a 355 volt lithium-ion battery pack from A123 systems and a 4000 amp Zilla controller. The bike is listed at 1350 hp, but can probably put down more based on the voltage of the batteries and the current rating of the controller. Here’s a video of the run. The engine noises at the beginning are from a car in the background.


Head over to gizmag for more details and pictures of the bike.
