Project E39 M5: K&N Filters and HPS Intake Hoses

by Martin Gonzales

In this installment of Project BMW E39 M5 we will test two very easy to install intake upgrades- the high flow K&N drop-in filters and HPS Performance Parts silicone intake hose kit. We will be doing individual dyno tests for each part to see if they can free up the S62's intake tract and yield some measurable power gains.

Nerd-O-Scope: Honeywell Garrett’s G-Series Turbochargers

by Khiem Dinh

The new Honeywell Garrett G-Series turbo line is the most exciting product launch since the infamous Disco Potato. Everyone knows the GT-Series turbos were getting very long in the tooth. The GTX launch was an upgrade with updated compressor aero and new families of v-band, T3 divided, and v-band divided turbine housings. The GTX Gen2 launch was a further improvement in compressor flow along with new compressor housing castings. But overall, the foundation of the turbos had stayed the same for two decades. Enter the G-Series which is a clean sheet design to address and upgrade every aspect of the GT/GTX series turbos. This is a true motorsports grade turbo for the masses.

Hondata's Land Speed Record Honda CRX

by Mike Kojima

A lot of armchair racers like to comment on Land Speed Racing saying things like "how hard could it be to go 200 mph at Bonneville, it's a big flat dry lake, all you have to do is floor it" or "I can almost go that fast down the freeway with my Civic with a turbo kit".  Well, all we have to say about that is to go try and find out just how good you are if you think you can.

Nerd Alert! Mazda’s Skyactiv-X Engine

by Khiem Dinh

As we are sure many of you have heard, the little car company that could, Mazda, has announced their Skyactiv-X engine with the technology to run Homogeneous Charge Compression Ignition (HCCI). Two major challenges to make HCCI work: timing of the combustion and smooth transition between HCCI and regular spark ignition. The HCCI combustion process has been researched for decades, but the technology to bring an engine using HCCI to market has been elusive until now.

So how did Mazda do it? We are going to take a few guesses, but as with most technologies, it didn’t happen overnight. In fact, we would say Mazda’s first big step was a few decades ago. The final piece of the puzzle is a technology Mazda has called Spark Controlled Compression Ignition (SPCCI), and we will exclusively get into how that ties into making HCCI work.

Project EP3 Civic Si: Fixing the @$#%! Steering for Good with SHG Motor Works!

by Mike Kojima

In our last edition of Project EP3 Civic Si, we thought we had fixed our car's bump steer and wandering steering with a roll center correction kit and a bump steer kit from Hardrace. Our car had serious issues since day one. When we first got it, no one wanted to drive it because the car would wander around on the freeway and everyone was afraid of getting pulled over for drunk driving.

So, we installed a bunch of suspension stuff and finished it with the Hardrace geometry correcting parts in the front suspension. With the car finally handling well, which is no small task with an EP3, we were finally having fun driving it hard. All was good for a couple of weeks, but then the wandering steering returned with a vengeance.

Top Lube for E85?

by Mike Kojima

Admittedly, none of us on Dai Yoshihara's Formula D team have much experience with alcohol. We all knew methanol was a superior fuel but highly corrosive. We knew it would require a lot of post event maintenance, which would include pickling the engine and fuel system by draining the methanol and running gas through the system to remove the methanol. However, we didn't expect to run into the issues that we did. We needed a solution and were recommended some things from other teams' crew chiefs that all came down to one thing.

The Tech Garage Low Cost Borescope!

by Mike Kojima

Just a few short years ago having access to a borescope was a luxury that few racers, engine builders, and hobbyists could afford. You would typically have to spend a few thousand dollars for one. They were not that flexible, in that you would either not be able to record images or would have to spend a bunch of money for camera adapters.

Project GD STI: Making More Power with Cobb Tuning and Precision Turbo Part 2!

by Mike Kojima

When we last left off with Project GD STI, we had just installed our drop-in ball bearing center section upgraded Precision Turbo. In our opinion, this is one of the best drop-in, non rotated mount turbos on the market for these cars, however, we wanted to be able to turn the boost higher. This brought the need for a tune utilizing Cobb Tuning's Subaru Flex Fuel System.

Project EP3 Civic Si: Can an Oil Change Affect Horsepower?

by Mike Kojima

A lot of people have asked this question before, and the jury has been out on whether this is something that is true or not. We have attempted to test to see whether certain brands of high-quality oil have a gain in power over others before with mixed results. Our dyno tests have always been inconclusive with the differences being too small to be considered or perhaps caused by variables such as differences in viscosity or sump level.

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.

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.

Project 5.0 Mustang (The White One) Building the 302 Coyote Engine!

by Mike Kojima

We were eager to get into our motor and install the Ford Motorsports parts that would basically enable us to rev to over 8000 rpm reliably and breathe better on top. The parts we accumulated would bring us to a spec about the same as the Ford Motorsports Aluminator performance crate engine and a little bit more than the Drag Racing Cobra Jet NA engine.
