Turbo Tech: Compressor and Turbine Map Details
By Khiem Dinh
We have previously covered compressor wheel technology and also how compressor and turbine maps are generated. Now we are going to dive a little deeper into the details of the compressor map and all-mysterious turbine map. Furthermore, we are going to see how compressor wheel and turbine housing A/R changes affect turbine flow and efficiency.

Since we opened up the back part of our exhaust with Greddy’s 85mm in diameter RS catback exhaust system, it was natural to next look for a better downpipe. After evaluating what was on the market, we decided to use the AMS Wide Mouth because of several unique design features which we felt made it stand out above the rest.

Project 370Z: Part 1 - Testing the AEM ETI Cold Air Intake
(Video Inside!)
By Mike Kojima
Nissan’s 370Z is a pretty damn good car. It is a nice improvement over the already good 350Z; it is more powerful, handles better, is lighter, stiffer and faster. We wonder why it doesn’t sell all that well as we feel that it is a class leading car at a reasonable price. Perhaps in this sluggish economy, the market for a mid priced two seat sports car, which for many people is a second or third car is too much of a luxury.

Project Evo X GSR- Testing the Greddy RS Catback Exhaust System
By Mike Kojima
In our last edition of Project Evo X GSR, we tested the K&N Typhoon Cold Air Intake with excellent results. Since the next logical choice in the path to modding our car is to free up the exhaust, we went to our friends at Greddy to get one of their RS exhaust systems to evaluate. The Greddy RS is a new line of exhausts that are constructed much like their race only systems. The main differences in the RS exhausts are that they allow the use of the stock catalytic converter and do not feature exotic titanium in their construction.

Basic Control Theory and Engine Management Systems By Vince Illi The modern internal combustion engine is a marvel of engineering. Compared to engines of the early and mid twentieth century, today’s engines are more powerful, more efficient, and orders of magnitude more reliable. These breakthroughs are mainly due to one thing: the engine management system.

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?
