Event Coverage: 2017 Indianapolis 500 Qualifying

by David Zipf

Week one of “The Greatest Month in Racing” started with left and right turns, kicking off with the IndyCar Grand Prix last week. This week, the right turns are abandoned and the focus is on nailing down the fastest time at one of the fastest tracks on Earth. One week of practice leads up to two days of qualifying for the 101st running of the Indianapolis 500 Presented by PennGrade Oil.  


Tested: Radium Engineering Coolant Expansion Tank

by Vince Illi

Recently, Radium Engineering released a kit to easily install their Coolant Expansion tanks onto 2011+ Mustangs. We test it out on our Grey Project Mustang 5.0 and discuss how an expansion tank works!


Lessons in Turbo Technology with Garrett - Burst Containment

by Mike Kojima

What is burst containment for a turbocharger, and why is it important?  A turbocharger is a system that has a lot of potential to cause a lot of bad stuff to happen to drivers, spectators, and surrounding equipment.  Why, might you ask? Well, a typical turbocharger can spin at up to an unfathomable 200,000 rpm for a small frame turbo and a still amazing 90,000 rpm for a large frame turbo!  That is a ton of potentially ass-kicking force. We will show you how much later and it's enough to make you cringe.


Project STurdteen: Installing Progress Sway Bars

by Rathyna Gomer

To run sway bars or to not run sway bars? That is the question. In the drift world, there's been a reoccurring debate if there is any true benefit to running sway bars. Sometimes it comes down to the driver's preference and sort of drift "style" they're aiming to achieve. As the debate continues, we opted to run sway bars. Sensei Kojima tells me there's no other way!

How do they make so much power?  We get a MotoIQ-exclusive, close-up look at the fascinating engine details of the 2012 Championship winning Matco Tools Top Fuel dragster driven by Antron Brown.

Project EP3 Si: Going 5 Lug with Wheels from Enkei and Nitto NT05 Tires

by Mike Kojima

Now that we converted our EP3 Civic from 4 to 5 lug hubs and added big brakes, there was no going back.  In order to drive the car, we obviously needed to do something about our wheel situation.  Our goal was to stuff the biggest tires we could into the stock wheel wells.  Unlike our hellaflush brethren, we want big and we want traction, not stretching a narrow tire on a wide rim and stupid amounts of negative camber.  


Project Infiniti G37S: Advan RZII Wheels & Nitto Invo Tires

by Aaron LaBeau

More than many other modifications on a project car, we suffer over wheel and tire choices the most. Mistakes are costly and easy due to sizing choices, but also aesthetically, it's really hard to get an idea of what a wheel will look like on your ride before it's installed. Or, you go down the road someone else has, making a guess on how much you want to trust someone else's judgement.


Japanese Cars That Don't Suck

by Mike Kojima

I pissed a lot of people off with my Japanese Cars Suck article a few weeks ago, where I expressed dismay at the boring state of the Japanese car industry. Japan Inc. seems to be producing either the uninspired transportation device or the trying too hard, over the top stuff that seems like something out of the Fast and the Furious or Transformers franchises.


Project EP3 Civic Si, Improving the Brakes with Fastbrakes, Stoptech and Willwood

by Mike Kojima

In the last edition of Project EP3 Civic Si, we explained how we went about converting our car from 4 lug to 5 lug hubs. We did this for two reasons: one to take advantage of the larger selection of 4x114.3 bolt circle wheels available on the market and to take advantage of the larger RSX Type-S wheel bearings and axles to stiffen up the bearing system in anticipation of performance fixed caliper brakes and more power from a possible engine swap.


Turbo Tech: Calculating Turbocharger Compressor and Turbine Performance Advantage with the New Honeywell Garrett GTX Gen2

by Khiem Dinh

In our Turbo Tech series, we have covered a lot of segments of turbocharger performance. We have looked at various aspects of compressor efficiency and performance, turbocharger mapping, and turbo sizing and matching among other things. This time around, we are going to do some more calculations on the turbine side, calculating pressure ratio and wastegate flow along with estimating power gains from the Honeywell Garrett GTX Gen2 turbos over the first generation GTX. You better get your Excel spreadsheets warmed up.


The Blackbird Fabworx Morpheus Miata!

by Mike Kojima

The cars created by Moti Almagor of Blackbird Fabworx have always caught our attention. More for less has always been the theme his creations. The Blackbird Fabworx cars have always eked amazing speed out of stock, very low powered engines. Lightweight, meticulous care in chassis setup, balanced brakes and carefully thought out aerodynamics have had a harmonious interplay in developing incredible speed from very little horsepower.


Testing Meguiar's Two Step Headlight Restoration Kit!

by Mike Kojima

Any car that has the newer plastic headlights will experience weathering and yellowing eventually. This is caused by UV light exposure degrading the protective coating on the surface of the lights. Once the coating is eroded, UV light makes quick work of the clear plastic underneath, and the light becomes cloudy and yellow. 


How To Do A 5 Lug Conversion the Right Way! Project EP3

by Mike Kojima

As we finally start to mod our much-maligned shop EP3, the car that everyone loves to hate, we came to the realization that the car had pretty big wheel wells. To us, big wheel wells does not mean room for offset, slammed to the ground ride height or dumb camber but room for big grippy tires!


Testing Radium Engineering's Advanced Self-Draining Catch Can!

by Mike Kojima

Having proper crankcase ventilation is critical on a performance engine, especially forced induction ones that have more blowby past the rings by nature. The pressure needs to be relieved. Excessive crankcase pressure can blow seals, cause severe smoking from the turbo and affect piston ring seal causing smoking and losing power.
