Lessons in Turbo Technology with Garrett!  Lesson 1 - The Compressor Wheel

by Mike Kojima

Recently we were privileged to be able to take a look behind the walls of Garrett Turbochargers' research and development facilities.  We were able to get an insider view of the intensive engineering inside a Garrett Turbo and viewed first hand what differentiates it from your typical aftermarket fare.  We were very impressed by what we saw and we would like to share it with you by breaking some of what a World Class OEM supplier puts into the performance turbos any consumer can buy into easily digestible lessons that we will be presenting to you periodically. Perhaps the key part of any turbo is the compressor wheel.  Let's look at what Garrett does to bring you one of the best compressor wheels on the market.

Nerd's Eye View: The Dyson Mazda ALMS P1 Prototype

By Mike Kojima

I am old enough to have been around during what I consider to be the golden era of American road racing in the 80's.  In this time we saw the rise of IMSA with the outrageous GTP prototypes and the exotic sort of production based GTO and GTU cars.  SCCA had Trans Am and even CART Open wheelers were sporting awesome technology rivaling Formula One but with closer more exciting racing.  I was lucky enough to have been a fan during this time and later on in the decade a participant.

An Inside Look at mountune's GRC Ford Duratec Engine!

by Mike Kojima

The current engines used in today's GRC Rallycross racers are some of the highest stressed production based engines in all of Motorsports.  Only Import Drag Racing engines see more stress and perhaps no production based race engines not even Time Attack engines are stressed for as long a period of time as Rallycross powerplants.

Breathing through a 45mm restrictor that limits power to "around" 550 hp, the mountune Ford Duratec puts out 625 lb/ft of torque.  Because of the restrictor, the Garrett Turbo pumps in 45 plus psi absolute of boost to make that power, generating an amazing 3200 psi of cylinder pressure.  To put this in perspective, this is more cylinder pressure than the Audi LMP1 Diesel!

"My Girlfriend's" Miata: Part 5 - Keeping Cool with Koyorad

by Daniel O'Donnell

I had a dream. In this dream a man would drive a car on the track. He wouldn’t own this car, yet he would have all the joy and happiness as if he actually owned it. His expenses would be low and his debt modest due to his loving girlfriend’s trust and/or gullibility. This was a beautiful dream that would leave me slightly sad when I awoke. Surely I couldn’t become this man. With my awkward personality and face only a mother could love, no girl would date me, let alone be foolish enough to let me drive her car at speed. But this my friends, is America. Dreams still come true and slowly, the dream has started becoming a reality. First the girlfriend, then the Miata, then the rollbar, seats and brakes to get it track ready. The last piece of the puzzle was improving the dumpster fire Mazda calls a cooling system in NA Miatas. With the help of Koyorad, my vision, foretold many years ago, is ready to be fulfilled.

Fabricating Turbo Headers and Exhaust Systems with Eimer Engineering and Burns Stainless

by Mike Kojima

How do you make a good turbo system even better?  We did it by enlisting the help of Burns Stainless. Our subject car had a turbo LS engine.  Although the car made lots of power, it had issues with lag, a drop in top end power, a ton of weight in the nose that negatively impacted handling and a propensity to burn up everything under the hood.

Tested: Burns Stainless NHB Porsche 987 Cayman and Boxster Exhaust System

by Mike Kojima

The Porsche 987 Cayman has long been one of our favorite cars.  Built from 2006 to 2012, the 987 features a midship mounted 2.7 liter flat 6 or a 3.4 liter for the S Model.  The Cayman has always offered stellar handling, perhaps it was the best handling car of it's time.

Many Porsche snobs pan the 987 because it's mid engine makes it not a real Porsche in their eyes.  Because of this the 987 can be found for pretty reasonable prices on the used car market. This makes it a great buy in the eyes of the enthusiast who really cares about performance.

With that in mind, our friends at Burns Stainless, purveyors of some of the finest header collectors, high quality bends and fabrication supplies for most of the hardcore race industry, have set out to build what is probably the best performance exhaust on the market for the 987 Cayman.

Project STurdteen:  Building the Competitive Drift Car from a Pile

by Mike Kojima

Rathyna Gomer is MotoIQ's sales manager but in her other life she is a Pro-Am drifter.  We are in the process of rebuilding her 350Z competition car and due to its complexity the process is taking a while.  In order for her to have a ride for the 2016 season, we decided to do some upgrades to her practice car, an S13 with the venerable SR20DET.  For a practice missile car, her S13 is pretty decently built but since it is a missile car, it has seen better days.  The car has been worked over by a conveniently placed practice lot pole and by doing tandem with a random on a drift day.  That and Rathyna's habit of doing body repairs by backing her car into the wall at balcony has left the old S13 in a state of ugly.

Keeping the BMW E92 M3 Cool With CSF Radiators!

by Mike Kojima

Although the BMW E92 M3 is a fantastic car, one of the best performance sedans made, it does have a few quirks. One of them, like most late model BMW's, is that the car's systems tend to run hot. Running hot on the track is one thing, but when you peruse user forums you find that for some drivers the cars can even run hot during street driving!

Demystifying the Camshaft: Part 2 – Terminology

by Jonathan Spiegel

In the first installment of this series, we took a fairly in-depth look at valve events, which, simply put, are the actions that are caused by the camshaft with regards to opening and closing the intake and exhaust valves. Ultimately, these events determine the power characteristics of an engine, because they control the amount of air/fuel mixture that the engine ingests at any given rpm, and they also control the flow of exhaust gases leaving the combustion chamber. Hopefully, Part 1 helped you to understand the processes involved in developing a camshaft design, so at this point we’re going to discuss the terminology that directly describes the physical parameters of the camshaft itself.

Wrench Tip: Get a Jewelry Cleaner

by David Zipf

Cleaning small parts can be a real hassle.  If you’re rebuilding, say, a carburetor, with lots of little jets, needles, and pins and screws, it can be very easy to break or lose something.  Some parts refuse to come clean, even when scrubbed with strong solvents (brake calipers are a great example of this).  So what’s a car guy to do?

Extreme Engine Tech: Building the Ultimate K24 Part 1 The Cylinder Head!

by Mike Kojima

Modding late model Honda/Acura engines is somewhat problematic lately.  Take for instance the late model K series engine.  Once probably the best naturally aspirated inline four cylinder production engine by far, the K motor in it's latest variant, the K24Z7, is a neutered, decontented version of its former self.  Found in the current 2012 and up Honda Civic Si and the Acura ILX, the K24Z7 still boasts a decent 205 hp and 174 lb ft of torque. This is slightly better power and much better torque than the much acclaimed bone stock K20A2 that everyone knows and loves.

Can the late model K motor be saved?  We will give it a shot with help from the guys at Motovicity Distribution!

Project GD STI: Getting More Power with Precision Turbo and Cobb Tuning! Part - 1

by Mike Kojima

Our STI has been driving around as a daily for two years now with all of the typical bolt ons.  It has been reliable at 318 whp with good driveability and fuel economy on regular pump gas, in other words a hassle free car that is very easy to live with.  Of course if good was enough, more is better and we could not leave good enough alone.

Extreme Engine Tech, Building a High Boost 2JZ-GTE with Brian Crower and JE Pistons-Part 1

By Mike Kojima

Building a 2JZ-GTE is not new on the pages of MotoIQ.  Pablo Mazlumian documented the building of a pretty healthy 2JZ in his Project Supra chronicles over the past couple years. We like the 2JZ powerplant.  It is a strong, robust powerplant capable of sustaining well over 1000 hp and has been competition proven in everything from time attack to drifting.  It is still quite a viable engine 23 years after it was introduced.

Project 5.0 Mustang: Getting More Power and Durability with Ford Racing

by Mike Kojima

We have just about maximized the bolt on potential of Project 5.0 Mustang in our last installment with the addition of the Ford Racing Cobra Jet intake manifold.  Now, in order to attain still higher power levels from our engine, we will have to dive into the internals

We are big believers in the benefits of parts designed by factory engineers with factory technical resources for factory race programs.  Many of the parts we will be using for our build are straight from the Boss 302R Grand Am and Cobra Jet NHRA drag racing programs. Factory engineered and best of all factory validated and proven on the track is good enough for us.

Project Focus ST- Making Power with Cobb Tuning!

by Mike Kojima

It's been a while since we have done much with our Project Focus ST but that is about to change.  In the past installments we worked on upgrading our car's suspension.  With the suspension done it's time to focus on other stuff.  What a bad pun.  The other stuff is going to be handled with the arrival of a big pallet of goodies from Cobb Tuning.

Our stuff from Cobb is mostly going to focus on getting more easy and plentiful bolt on power from the engine with their Stage 3 Power Package with a few other goodies to enhance the car's handling as well.  Man we cannot get away from these focus puns.

Project 5.0 Mustang. Improving the Breathing With Ford Racing and Cooling with CSF

By Mike Kojima

In previous installments of our Project Mustang we had installed most of the common bolt ons for our 5 liter Coyote engine.  We had gotten a pretty decent boost in power but we had noted that our power would really fall off at higher RPM, more that what we thought a free breathing 4 valve motor should.
