Say I would like to accelerate to a specific speed while going up a hill with a moderately steep grade. Which gear is better for fuel economy and which is better for the longevity of the engine?

Project Husqvarna TE610 Part 1: Dual Sport Adventure Bike Options
By Dan Barnes
Buying a semi-obscure Italian motorcycle and riding it out to the middle of nowhere may not seem to be a well-thought-out plan, but really, there was some thought. I swear. An off-road bike is ridiculous fun, but it's also kind of like having a track car that needs a trailer. The goal of this project is a go anywhere, do anything bike.

Project Civic EJ: Fast Brakes Rear Disc Brake Conversion Kit
by Chuck Johnson
After completing the install of the front Fast Brakes big brake kit, we knew that we had to do something about the drum brake lameness that was taking place on the rear of Project Civic. Project Civic had been retired to commuter car only status almost a decade ago and since then had only the basic maintenance performed. We were pretty suspicious that the rear drums weren't contributing any work in the whole braking equation since there seemed to be an abnormal amount of front brake bias. Never mind that the rear drums and shoes had not been replaced ever even after 260,000 miles of use.

How To Degree Cams
By Aaron Bonk
An engine works best when the right things happen at the right time. Say your spark fires before your pistons are in their right spots—you might embarrass yourself on the dyno. You might even end up with a scenic view of your bottom end. The relationship between an engine's crank and its cams is no different. The rise and fall of its pistons has to sync with the opening and closing of its valves, which happen to be controlled by its cams. This is even more important to pay attention to once aftermarket cams, adjustable cam gears or other mismatched components are introduced as well as once an engine's block or cylinder head have been resurfaced. All of this should be enough to make you want to degree your cams.

In part one of our series we spoke about the importance of good suspension which is probably the first major step in setting up a car for drifting. Although the suspension is really important, perhaps just as important is a good limited slip differential.

Physics Lesson - Friction
By Khiem Dinh
Fric-tion [frik-shuhn] frik-shuh n
Noun
1. Surface resistance to relative motion, as of a body sliding or rolling.
We like friction between tires and whatever surface they are riding on. However, there are two types of friction: static and kinetic. Static friction is when there is no relative movement between two surfaces. Kinetic friction occurs when one surface of an object slides across another.
