How to Build a 5.0 Coyote Engine on Any Budget

by Mark Gearheart

Many people look at the 2011-current Coyote 5.0 engine platforms as a complex and expensive engine to build. In reality, they are actually very cost effective and can be tailored from mild to wild with ease. Want to make 350 horsepower or 1,500+? No problem. In this article we are going to explain the different levels of Coyote engine building. We teamed up with a host of manufacturers and L&R Engines to build us a Coyote engine for road racing duty on Project BOSS 302Revival.

Nerd Alert Part 2! SKYACTIV-X: Were Our Predictions Correct?

by Karla Pestotnik

When Mazda first announced its infamous, new SKYACTIV-X engine, we made some preliminary guesses about its workings before any information was released. Guesses are guesses, but now that Mazda has released more official information about the all-new and exciting Homogeneous Charge Compression Ignition (HCCI) engine, it seems that we weren’t too far off. We recently got to poke around and even test drive their ten million dollar prototypes!

Project Porsche 991 GT3 RS: Dundon Motorsports Headers and Exhaust System

by Mike Kojima

It's tricky to attempt to improve the engine performance of a supercar, especially when its one that puts out 125 hp per liter like the Porsche GT3 RS does. When it comes to NA power, only the Porsche 918 hypercar and the Ferrari 458 Speciale have more punch per liter. With its screaming 8800 rpm redline, titanium internals and a sky-high 13:1 compression ratio, there isn't a whole lot more that can be done without serious engineering, beyond what most tuners can do.

We Test the Bimmerworld Exhaust and Epic Motorsports ECU Tune for E90/E92 S65 V8 BMW M3

by Pablo Mazlumian

When the S65 4.0-liter V8-powered M3 was released, enthusiasts loved the power, thanks to its 8000-plus RPM capability. However, many also deemed it not torquey enough for a V8. With this exhaust setup and tune, an M3 will make some torque, as shown in our testing at Modified by KC.

Improving Dai Yoshihara's Formula Drift Engine Wear With WPC Treatment!

by Mike Kojima

The world of Pro Drifting is a brutal place for machinery. Since I started my involvement with Pro Drifting 10 years ago, I have been amazed by the appetite for parts a pro car possesses. In all of my engineering career, I have yet to be involved with a motorsport that eats more expensive stuff on a regular basis.

Project S2000 AP1: Deatschwerks Fuel Pump Install

by Vincent Soto

All was not right with our Project AP1 S2000. It was making some louder than normal sounds that were coming from the fuel pump. The car would struggle to start as if the car had low gas or no gas at all. After some forum research and some diagnosing with a fuel pressure gauge, we had come to a conclusion that the fuel pump was bad.

After having the car for 5 years now, it was expected for it happen eventually. Since we got the car from the auction for 3200 dollars, there were no records of the fuel pump being changed or of any (well there was some records for tires bought in 2003) maintenance at all. With that being said, we started to look at fuel pumps on the market. In the end, we decided the go with Deatschwerks DW200 fuel pump (9-201-1000).

Building an FA20 Race Engine for Michele Abbate: Part 1- Planning the Internals

by Mike Kojima

We have known Michele Abbate ever since she was a college student doing track days with her trusty Mazdaspeed Protege and have followed her career as friends as she has progressed up the ranks from recreational driver to a Scion Sponsored driver in SCCA's GT1 class. 

Up to now, Michele has been running her car with a bone stock FA20 engine at a very low boost street blower drive ratio. Although this is decent power, she needs a lot more to be competitive in one of SCCA's fastest classes for production-based cars.

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.
