by Vince Illi

You use your brakes a lot.  But do you really know how they work?  We test out Hawk Performance’s new HPS 5.0 pads and DBA’s 4000-series rotors and examine how brake pads and discs work together to stop your car!


Event Coverage: ChumpCar Canada

by Frank Ewald

Newly formed on January 1, 2015, ChumpCar Canada is now a distinctly separate organization from the Optima Batteries ChumpCar World Series. Months of planning, working behind the scenes, and a lot of sweat, tears, and laughter resulted into the roar of motors firing up as forty-two cars participated in the inaugural race. Held at Ontario's storied Canadian Tire Motorsport Park, you could sense the excitement in the air. Photo-journalists from several publications, yours truly included, were present to witness this new race organization's first race.


Project Ford Fiesta ST- Making the Jump to a Race Car with SPD Motorsports Part 2!

by Mike Kojima

When we last left our Project Ford Fiesta ST it was being converted into a race car by the capable hands of SPD Motorsports.  As progress continues, SPD  is working on installing a crash resistant fuel system using components from Fuel Safe, Deatschwerks, and Aeromotive. Other details like Lexan windows, brake ducting and the interior are coming together as well.


Extreme Engine Tech: Technosquare's Monster Naturally Aspirated Toyota 4AG - Part 2

Extreme Engine Tech: Technosquare's Monster Naturally Aspirated Toyota 4AG - Part 2

by Mike Kojima

In our last edition of the building of Technosquare's monster Toyota 4AG, we mainly looked at the details of the bottom end.  Now we will finish our tour of the bottom end and delve into the engine's cylinder head which is the heart of any high performance engine.

The 83mm x 83 mm stroker motor gives 1800cc.  The 200 extra cc's makes a huge difference, fortifying the 4AG's notoriously narrow power band. The engine cranks out over 250 crank hp, more than the most highly developed Formula Atlantic engines of yore and 30 more hp than the previous 1600 cc version of this motor. Here it is, re released again for your reading pleasure!



Nerd’s Eye View: Erik Buell Racing 1190RX

by Khiem Dinh

When your average guy thinks of a sport bike, typically Honda, Yamaha, and Kawasaki come to mind from the land of the rising sun. For those with more means, Ducati, Aprilia, and MV Agusta from the land of love are the crotch rockets of choice. Even the Germans have jumped into the fray in relatively recent times with BMW launching an assault on the established players from Japan and Italy. When it comes to America, Harley Davidson comes to mind with big rumbling V-twins in big hogs. But there is a glimmer of hope.


Vetting the Vet's Vettes – A Look Inside MTI Racing

by Erik M Jacobs

Reese Cox cut his teeth behind the wheel of a Corvette, and his experience shows. In 1993, during the heyday of his time as team manager for Tommy Morrison Racing leading ZR-1 Corvettes through the 24 HRS of Daytona and other IMSA series, Reese founded MTI (Motorsports Technologies Incorporated) Racing. The 1998 SCCA World Challenge Rookie of the Year knows a thing or two about making these sleek bowties fast and powerful, and he was kind enough to open the doors of their shop to MotoIQ. Inside, we found a lot more than just some fast coupes.


'64 Corvette: 2015 Edition!

by Frank Ewald

The lines on this C2 Corvette are stunning. Whether you are looking at it from the front, the back, the top, or the sides this car is an incredible work of art. The one that I am currently looking at and writing about is a 1964 Corvette StingRay and is now a fifty-one year old automobile. While this particular car has undergone a frame off restomod the paint and body have not been touched. The body on this car is in amazing shape and the paint is almost perfect. The only sign that this car has had any changes made are the massive brake rotors and calipers peeking out from behind the wheels and replacing the original drum brakes. That is, until you see under the hood or have the car up on a hoist.


Project Tundra: Leveling it out with a Hellwig Big Wig Air Lift

by Mike Kojima

In the last edition of Project Tundra, we had installed Hellwig's adjustable rear antisway bar in an effort to improve our truck's balance and limit body body roll to help keep our stability control from activating prematurely. 

Now to finish up our chassis tuning we wanted to address a problem all trucks that tow have. With tongue weight in place the back of a trucks sags lower and the front lifts higher.  This makes the handling a little squirrely at times, the steering getting light a lot due to the geometry changes of the front end when under droop. The heavily loaded rear suspension is also prone to bottom out with bigger enclosed trailers which can make things interesting and possibly damage the trailer jack.

To fix this by leveling out our truck without hurting our ride, we decided to go with a set of Hellwig Big Wig air bags.  The air bags can increase the rear suspension's capacity by 2700 lbs and restore the proper ride height improving stability and laden ride.  When finished towing, the bags can be depressurized for a stock ride height. and smooth ride.


Technosquare Howard Watanabe 4AG Engine Build

Extreme Engine Tech:  Technosquare's Monster Naturally Aspirated Toyota 4AG - Part I

by Mike Kojima

The Toyota 4AG is a historic engine, one that was essential in launching sport compact car culture in the USA.  In 1985 the 4AG first rocked the automotive world.  It was the standard engine in the Toyota Corolla GTS, the famed Hachi Roku AE86.  The AE86 was the last of the RWD Corollas and Toyota made history by equipping it with the revolutionary 4AG engine.  Not to be forgotten, the AW11 MR2 mid engine sports car was also powered by the 4AG.

Turbo Tech: Size Matters! - Part 2

by Khiem Dinh

In Part 1 of Size Matters, we went over the basic concept of sizing the turbo for the application and desired torque curve shape to match the intended use of the vehicle. You know, because a couple million people a year ask what size turbo they should get for their _______ (insert application here, i.e. car, motorcycle, boat, scooter, lawn mower, etc). Once everyone gets a bit more turbo savvy, they learn of the concept of boost from a small turbo does not equal boost of a big turbo. Well, we’re going to explain why.


Project VA WRX, Upgrading the Bushings and Swaybars with Superpro Part 1

by Mike Kojima

We decided to be different and tackle the Subaru WRX as our latest Project Car because it's big sister, the STI has been always getting all the attention.  More people can afford the WRX which we consider to be a performance bargain and more enthusiasts drive them.  We will be working with ARK Design to get this car going and make it more fun to drive. 

One of the first things we did as is typical on most of our project cars is to work on the suspension first.   Since we are still deciding on what to do for dampers on our project, we decided to start with changing the soft rubber suspension bushings with some polyurethane parts by Superpro.


Project Tundra, Getting More Cornering Power (and less stability control activation) with a Hellwig Adjustable Rear Antisway Bar

by Mike Kojima

If you have been following Project Tundra, you know we have been struggling with excessive activation of our truck's stability and traction control systems.  The improved power of our supercharged engine and additional traction of our larger tires have been driving the electronic nannys of the truck's OEM systems crazy.  We were hopeful that a new adjustable rear antisway bar from Hellwig would help.


Project Nissan 350Z UPDATE - New Owner New Plans

MotoIQ Staff Report

Furious 7 stunt driver has taken over the controls (and ownership) of MotoIQ Project Nissan 350Z! Our 350Z project was originally built as a reliable street/track performer, but like any car with an overworked odometer the miles have been stacking up and the original engine finally threw in the towel. It's no surprise either, as it has been in the hands of stunt driver Jay Lynch for almost the past year. Jay has not only been using the car to work on his stunt driving techniques, but Jay has also been using the car to pass down his driving skills to his daughter Brionna Lynch.


NX GTi-R: Vacuum Routing

by Frank Ewald

One of my tasks for this winter was to ensure that all of the vacuum lines on the SR20DET were accurately connected. Small stuff but I have not been positive that it was completed properly. I have put off an accurate setup for too long. While I read tons about this on SR20-forum, I went to my buddy Will at PZ Tuning for the expert's touch. After all, if you miss the small stuff it may damage your car.
