Basic Performance Upgrades. These modifications are: A full length three inch down-pipe (with or with-out high flow cats), 3″ (75mm) or bigger cat-back exhaust system, raised boost (18psi), and the required boost cut eliminator (GReddy BCC) needed to achieve that boost without activating the factory fuel cut-off at 14-15psi. These are the modifications that have proven to provide the best HP-to-$$$ ratio.
The ads GM is running, including those they ran during the Summer Olympics, reflect those necessary changes. Another aspect of those ads, that very few people are aware of, is the Cobalt gets better EPA fuel mileage ratings than the Aveo. The Cobalt is a larger car, weighs more and has a bigger engine. The engine is the same basic design as the Aveo. Why does it get higher MPG? Because the profit margin is higher!
To remove this part of the car, position yourself under the vehicle, until you are facing the catalytic converter price guide. You will see pipes that bolt into either end of the converter. Unbolt the system starting from the back, moving forward. You may find that the bolts themselves are rusty, and will need to be forced open.
Kilowatts – A measurement of power. The more kilowatts, the more power – and in car speak this usually means greater speed. 1 kW = 1.341 bhp (brake horsepower).
One of the major contributors to the recent rise, and then drop in fuel prices, was the part played by the futures and commodity traders. A disproportionate percentage of the bailout moneys went to those who played the market up, took huge profits and then were playing the markets down. Many of them were skimming so much off the top, they went bankrupt in the process. If you have enough clout with the powers that be, Goldman-Sachs is a good example, you can get the taxpayer to bail you out after you’ve already fleeced them. Henry Paulson, the Secretary of the Treasury, was one of Goldman-Sachs’ major players and CEO’s.
Torque – measured in newton metres (Nm), torque is a way of measuring the force with which the engines turns. That force is translated into forward movement. Simply put, torque can be thought of as how hard the car is shoved forward as you put your foot down.
A flickering warning light is serious. A light that is showing a clear pattern of off and on is your worst case scenario light. This likely means you have a severe emission control failure and every time that light flashes your catalytic converter is being damaged by a misfire. This means your catalytic converter is overheating and can start a car fire. Pull over and get towed. This is not a time to try and make it a few miles to your destination.
