A Look Inside the Mackin Industries/Turn 14 Distribution FR-S Pikes Peak Car

by Mike Kojima

The Evasive FR-S with its wild aero and wide body had been shipped to Japan for a time attack battle at Tskuba Circuit leaving the team without a car to compete in.  Instead, for this years Pikes Peak Effort, Evasive teamed up the Mackin Industries to run their FR-S up the mountain in the Time Attack 1 class. We had previously worked with Evasive and Mackin on setting up this car at Super Lap Battle so it was reasonably dialed in.  However, it needed another round of upgrades to tackle Pikes Peak. The work was done on a super low budget in quick order.  Turn 14 Distribution was an essential part of the effort donating many parts and helping with the budget. 

Lets take a look at what was done to the car prior to the event!


 

EVENT COVERAGE: Street Driven Tour - Virginia International Raceway

by Martin Gonzales

The grand majority of MotoIQ readers have been to some sort of motorsports event. Whether participating in a track day or simply spectating at a pro event, we're always looking for ways to get our motorsports fix in. Until now we have always had to make a choice between being part of the action or just watching. Not anymore! The Street Driven Tour is a motorsports bash with something for every gear head. You want to watch some road racing, they've got it. You want to go on a drift ride along, they've got that. Want to play some drift-soccer, they've got that too!


 

Radical Canada

by Frank Ewald

You likely have your perceptions about Canada - the country north of the United States that is full of mountains, forests, and calm, happy people. So I am sure that the title Radical Canada may make you wonder. Perhaps you have read some of my other articles and realize that, on the race track, there are some pretty radical Canadians. Here, however, my focus is upon the Radical sport racer.


 

Blacktrax Performance S2000 Motorsport Makeover: Part 4 - Final Bodywork, Second Engine Build, Testing, and First Races

by Edward Hu

In our last update on the Blacktrax Performance S2000, nicknamed “Irene”, we covered the basic motor internals, exchanging the rubber subframe mounts with solid pieces, and the rubber suspension bushings with spherical units. We had made some body modifications in order to fit the new wheels and tires, and also for the final aero pieces, which will be covered first in this update on Irene.


 

Project Lexus SC300 Road Racer: Part 1 - Intro and Fuel Cell

by Erik Jacobs

This is Damnit. All of my cars have nicknames, but this one earned its name long before I ever picked it up. I could write a book about everything that’s either been wrong or has gone wrong during the previous phases of this build. That being said, this is my first “real” race car. I intend to use Damnit targeting NASA Pro Racing’s ST2 class. Super Touring is a power-to-weight class with fairly open rules. Pretty much as long as you don’t move suspension pick-up points you can do a lot of things. ST2 is limited to 8.0:1 (lbs per horsepower) which, with a ~3200lb SC300 limits me to ~400WHP. Power, engine and other info will come in subsequent articles. Today, we're prepping to install a fuel cell.


 

Sneak Peek: The Indy Cars of Team Lotus

by David Zipf

We've shown you lot and lots of brand new IndyCars lately, but what did the racing world look like 50 years ago?  Lotus decided to enter the 500 in 1963 and they did so in their own unique style.  We got a chance to look at some of the cars that not only turned Indianapolis upside down in the 1960s, but helped cement Jim Clark as one of the most talented and legendary drivers to have ever lived.


 

Project Professional Awesome Time Attack Evo: Part 3 - Fuel System

by Daniel O'Donnell

At Professional Awesome Racing, we take pride in thinking through problems and coming up with solutions that are as efficient and reliable as possible, all while fitting into a modest budget. We try not to do things that other people do just because “it’s always been done that way.” As you can read in our previous articles, this has lead to unique designs with our chassis/roll cage and powerplant. We like to think this same mentality translates into our fuel and computer systems and that’s the topic we’ll dive into today. So enjoy reading while sitting on your favorite throne or perhaps fire up MotoIQ at work with a finger quick to pop up a spreadsheet if the boss walks by.


 

PZ Tuning's 660WHP Awesome Civic

by Frank Ewald

There is nothing like seeing a race car in action. Even more, there is nothing like watching a race car move from a bare shell into a Global Time Attack Unlimited Front Wheel Drive class winning race car. William and Noreen Au-Yeung welcomed me into their store, Point Zero Audio and PZ Tuning, then opened the shop doors so that I could follow along on the build of this Honda Civic.


 

Extreme Engine Tech: Building the Ultimate K24 Part 3 - The Finished Goods!

by Mike Kojima

We have been working with Motovicity for the last few weeks to demonstrate the building of a potent Honda K24Z7 motor, built completely from in stock and off the shelf parts available from Motovicity themselves. We chose the K24Z7 as it is currently the OEM engine for the Civic Si and is relatively difficult to modify due to it's emissions bound cylinder head.  Our goal is not to build a dyno queen or a drag motor but to build a strong K motor all from off the shelf parts with the intention of getting the most power possible on pump gas with the widest most useable powerband. 

In the last two editions of our series we focused on the cylinder head and bottom end of our K24Z7. We swapped to an earlier model K20Z3 head  to get Vtec on the exhaust side and and removable exhaust manifold and installed Skunk2 camshafts, Kelford valvesprings and Supertech valves better suited for turbocharged use. For the bottom end we added lower compression JE pistons and stronger K1 rods, removing the problematic balance shafts while we were in there.  

Now it's time to finish off our motor. 


 

Nerd's Eye View: Mazdaspeed Mazda 767B

by M-P Spierer

The Mazda 767B is the third of four IMSA GTP predecessors to the iconic 787B that took the overall race win at the 24 Hours of Le Mans in 1991. The 767B was first raced in 1989 and is widely considered a success due to its reliability and for the part it played in progressing Mazda to the top of the podium in '91. This heritage is important because the 787B marked the first and only overall Le Mans win thus far from a Japanese manufacturer. It is also the first and only overall win using a rotary engine. So let's celebrate that heritage and take a closer look at some cutting edge 1980's technology.
