ARK Design MFD

Project EVO IX Part 5: ARK Designs and Mitsubishi Products

By Mike Kojima

Every car with aspirations of track driving needs accurate instruments, the EVO is no exception.  Factory gauges are very inaccurate, often lagging far behind what is actually going on.  In the case of the EVO, most of the important gauges are simply missing.  The EVO only has a water temperature gauge, ridiculous for a high performance car.  We installed an ARK Designs MFD To fix this.

Go fast Bits G-Force boost controller!

By Wes Dumalski

Our mates overseas at Go Fast Bits have been hard at work perfecting a new feature packed boost controller called the G-Force that has hit our shores! This cutting edge unit has all the bells and whistles any boost junkie could ask for. We recently put the G-Force through it's paces on Project 200SX in an effort to share our feedback with Go Fast Bits themselves..... Here are our impressions of the unit they sent us.

Project Miatabusa attack of the weight weenie

Project Miatabusa Part 3 - Attack of the Weight Weenie!

by Dave Coleman

Our Miata's stock 1.8-liter weighed 296 pounds. The Hayabusa engine, without gearbox or header, weighed 135 pounds. So it looks like we should have 161 pounds shaved right off the bat. But on top of that, we've managed to save another 73 pounds just by discarding the parts of the car that are really only required by the kinds of people who wouldn't put a Hayabusa engine in their Miata in the first place.

AEM ETI intake test

AEM ETI Technology Enhances Cold Air Intake Performance

By Mike Kojima

If you have been in the game of modifying cars for 10 years or so and got your start modding compact cars, you probably remember the good old days when adding a cold air intake was probably the first or second engine mod you did to your car.  In those days a really well designed intake could add as much as 10 or more whp to your car's output and even the most basic poorly designed ebay intake usually added at least a few dyno verifiable horsepower.  A cold air intake was considered to be a good bang for the buck modification and thousands were sold.  Even the most mechanically inept were usually able to install an intake with a few simple hand tools.

Project Toyota Tundra TRD Intake

Project Toyota Tundra Part 2, TRD Cold Air Intake

By Mike Kojima, photos by Jeff Naeyaert

In our last edition of Project Tundra, we discussed why we selected what is now our favorite truck of all time. We basically needed an office hauler, capable of carrying parts, carrying our staff and towing race cars all over the place under all conditions.  It had to tow like a diesel and be reliable like a daily driver.

The Ultimate Guide to Suspension and Handling Part IV: Reduce weight transfer

By Mike Kojima

Now that you have reduced body motion and improved steering response, and tuned out under or oversteer to improve the chassis balance, our next step is to reduce weight transfer. Weight transfer is the movement of weight from the inside to the outside wheels of a car under cornering.

Project Honda S2000 Stoptech big brake upgrade

Project Honda S2000 Part 3- Brakes that don't Break

By Khiem Dinh, Photos by Jeff Naeyaert

Although the Honda S2000 is one of our favorite all time cars, one of the parts we like the least about the car is the brake system.  Although they are perfectly adequate for street duty, the stock brakes do not match the excellent handling ability of the car and are not up to snuff for track day use. S2000s that are tracked heavily, especially on non-staggered setups running 245 or 255 width front tires, are prone to cracking front rotors.  The added traction from the wider front tires means more braking power and therefore more heat the front brakes must dissipate.  This added heat is simply beyond the capacity of the stock brakes’ design, leading to oft cracked rotors.

To see what else we did to project S2000 click here!

Performance Friction Brakes

Performance Friction, State of the Art Braking Systems

By Mike Kojima, photos by Jeff Naeyaert

Those in the know are very familiar with the Performance Friction company. Performance Friction brakes are found on most of the paddock at the highest levels of pro racing. IRL, NASCAR and ALMS teams go to Performance Friction as the brand of choice for their brake system and friction material needs.

Performance Friction is also a brand of choice in the tuner market. Many of the top Time Attack cars run Performance Friction pads and brake systems as well as a legion of club racers. Performance Friction pads are also a favorite among the staff at MotoIQ. We are enamored of the performance and consistency of the product.

Project 200SX - Track Ready?

By Wes Dumalski

It's no secret that driving your car at speed on a road course will bring to light all of the car's weaknesses. After sorting the motor and suspension we decided to take Project 200SX to a few track day events to put the car through its paces. While the car has proven dead reliable we certainly found its shortcomings.

Air fuel ratio and compression ratio explained

Suck, Squish, Bang, Blow part 3- Compression Ratio and Air Fuel Ratio

By Mike Kojima

In our last edition of our ongoing series on engine tuning and theory, we explained how the 4-stroke cycle works.  Now we are going to break down a couple of common and very important terms that you will hear all the time when discussing engines that you must understand if you are going to successfully tune or select parts for your motor.  This information can also help prevent you from getting ripped off by bogus speed shops.  This can also help prevent you from being steered wrong by SPE's, FFF's and other lameo guru types that inhabit various forums and online resources.
