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!

Project Mustang 5.0 (White)- Reducing Understeer  with Ford Racing

by Mike Kojima

The McPherson strut suspension found in our Mustang has some good and bad points.  The good points are that it is simple, lightweight, inexpensive to produce and takes up minimal space in the car. This in turn allows room for more narrow shock towers so the wider DOHC Coyote engine can fit. The bad points are few but perhaps the worse is that strut type suspension has some compromises when it comes to geometry, particularly when lowered.

The benefits of lowering a car can be nullified in a strut car if the car is lowered by more than just a little.  Often lowering a strut equipped car makes the car handle worse, particularity in the front of a strut equipped car where over lowering manifests itself as increased understeer.  Some lucky owners of cars where there is a healthy aftermarket have off the shelf solutions to fix the front suspension geometry.  If you are a Mustang owner you are in luck as Ford Racing has a well engineered geometry correction solution available for you right at your local dealership's parts counter.

Project Lexus SC300 Road Racer: Part 2 - Mounting the Fuel Cell

by Erik Jacobs

When we last left our Project SC300, aka “Damnit”, we had just sat the new Fuel Safe/Radium Engineering fuel cell into the trunk area in order to mark out where we would cut. We had also removed the rest of the factory stock hard fuel lines to make way for our fancy new braided stainless lines that we will assemble ourselves. Now follow along as we mount the cell in place.

Project Autocross BRZ: More Nameless Art

by Bart Hockerman

We all know when Nameless Performance has an idea on how to increase the performance further on their designs they will put into motion a plan of attack and some awesome fab work. They are pretty much the most aggressive company I have come across in my years of dealing with manufacturers across the spectrum. Improving upon their design is one thing they are allowed to do when building parts per your order. You the customer get the most current fabrication of the latest, greatest part they can make at that time.

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.

Evaluating the HKS Max GT R35 GT-R Coilover Suspension System

by Mike Kojima

Not so long ago we evaluated HKS's new Max ST coil over suspension system on a Honda AP2 S2000.  The S2000 is a pretty decent handling car from the factory that is pretty suspension sensitive, the AP1 in particular has a lot of toe change with suspension moment and some wonky suspension can make it quite a handful.  

For our next evaluation we decided to try the other HKS coilover in the lineup the Max GT damper. While the Max ST is calibrated for the serious driver being set up like a hard core street and or weekend warrior track day shock, the GT is made for a mildly performance oriented driver that wants to lower their vehicle with a decent ride and have handling that is a step up from stock but with little sacrificed in the way of ride comfort.

Demystifying the Camshaft: Part 1 - Valve Events

by Jonathan Spiegel

As we all know, the key to making power is to create pressure in the combustion chamber - and to create that pressure at the right time. This pressure works to drive the piston down in the cylinder and cause the crankshaft to rotate. The more air/fuel mixture you can get into the combustion chamber, the greater your potential for creating more pressure, and more power.

Extreme Engine Tech: Building a BMW S52 - Part 2: The Cylinder Head

by Nick Betz

If the engine as a whole is the heart of a car the cylinder head would be all the supporting parts that make the heart pump. Without the opening and closing of certain valves of the heart you can’t get blood to flow into the atriums and out the ventricles. Just like the heart, a cylinder head has multiple valves that need to open and close at specific times to get air in to and exhaust out of the combustion chambers to keep the engine pumping.

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.

Project Autocross BRZ: Swapping The Feal 441's to KW V3's

by Bart Hockerman

Since the first installment some time ago things have changed with the BRZ. KW has graciously supplied us with KW V3’s for use on this Project BRZ. With that in mind the 2014 SCCA Spring Nationals was the last event for us on the Feal 441’s. So we went out and gave them the last “Hoorah”. We brought home a solid 2nd and 4th place finish at the ProSolo and another solid 2nd place finish for the National Tour.

Extreme Engine Tech, Building the Ultimate K24 Part 2 The Bottom End!

By Mike Kojima

In the last edition of our series, we had focused on the engines top end switching to a an earlier model K20Z3 head with Vtec on both the intake and exhaust sides of the engine and a removable exhaust manifold all big steps in getting more performance.

Now We will be turning our attention to the engine bottom end, fortifying it for turbo power! Like the head, our goal will be to use off the shelf parts available in stock at Motovicity in the build. This engine is not some super esoteric custom build but one anyone could easily duplicate.

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!

Extreme Engine Tech: Building a BMW S52 – Part 1: The Short Block

by Nick Betz

There comes a time in a project build when you just have to throw everything out the window and rewrite your storyboard. Over the years we’ve been bolting on parts to Project E36 323is and not seeing the gains we were looking for. Sure it’s been fun but it’s time to make some real power. We had plans for an M50 manifold swap paired with M3 cams, bigger air meter, headers and throttle body but as the old adage goes, there’s no replacement for displacement, so that’s where our journey has taken us.

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.

GTA Road Atlanta: #teamcanada is Coming

by Frank Ewald

Canadians are known for their love of hockey. We are known for having a Tim Horton’s Coffee shop on every other corner of some cities.  We are known for putting the letter ‘u’ in words like neighbour and colour and doughnuts. We are known for being the small country above the United States of America – your northern neighbour with a much larger land mass yet a drastically smaller population. We are known around the world for being a country of polite and respectful people – accepted around the world in more places than American Express. Canadians are known for great Time Attack builds and drivers – whoa, you say! Things were going okay until that bit about Time Attack!
