Building a NASA NP01 Prototype the Right Way with StopTech!  Part 1

by Mike Kojima

Last November we had the chance to drive and evaluate NASA's NP01 Prototype built by Elan. We loved the car and eagerly awaited its availability. Fast forward a few months and our friends at StopTech were able to get one of the first NP01 kits.  Since StopTech's facility was undergoing expansion it was agreed that the car would get built at the palatial MotoIQ mega shop and that we could do a series of articles on what it takes to build a winning NP01.

Wrench Tips #31: Cardboard Aided Design

C.A.D. - Cardboard Aided Design

by Dan Barnes

It was an epiphany when I walked into a race shop and saw the interior tin work of an under-construction Rolex GT car mocked up entirely in white illustration board, clecos and blue tape. I made a mental note: I can do that! I can even afford that! Now my projects turn out better with the use of old cereal boxes, scissors and tape.


Project Autocross BRZ:  Finding More Grip with KW Clubsports

by Bart Hockerman

It has been some time since we last saw the MotoIQ Project Autocross Subaru BRZ.
Over the winter months here in the Midwest it gets really cold, our roads turn to asphalt crater fields and those of us who like to keep our cars free from rust allow them to hibernate for winter.
During this time we plan for the next season acquiring parts and pieces that will allow us to attempt to become even more competitive. During our latest off season there was much discussion on what would allow this project to take another step forward.


 

Project [Rotary] FD RX-7: Part 6 - V-Mount Cooling System (Overview and Intercooler)

by M-P Spierer

The cooling system in the FD RX-7 is widely regarded as its most glaring weakness. Many of the engine's cooling components are constructed out of plastic, the intercooler is wildly undersized, and the orientation of the radiator does not allow for proper airflow to the intercoolerIn the next two installments of Project [Rotary] FD RX-7 we tackle these issues by implementing a 100% custom V-mount cooling solution. 


 

Improving Towing Capability with Hellwig and Bilstein Part Two

by Mike Kojima

In part one, we had installed Hellwig air springs, rear anti sway bar and Bilstein 5100 series shocks on our workhorse 2014 Chevy Silverado truck.  We were super impressed with what the rear suspension did to make our towing experience more pleasant and much safer. However, due to time constraints we did not have time to do the front suspension.

Nerd’s Eye View: Standing Mile Turbo ‘Busa

by Khiem Dinh

A lot of people like to go fast. For many, a quarter mile is just not enough. The need for speed has bred the standing mile competition. The power levels have gotten so high that the RWD cars have stream rollers for rear tires. Many others have gone to AWD cars for more traction. And then there are guys like Hussain Alsowaigh who puts all the power down through a single tire.

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!

by Frank Ewald

When your business allows you access to a dyno 24/7 and your mind is always in overdrive trying to find new ways to make horsepower, then you are in the perfect spot to be coming up with ideas, developing these ideas, and testing these ideas. Meet Sasha Anis, owner of OnPoint Dyno and a true racer at heart. His naturally aspirated 420 wheel horsepower Nissan 350Z and its individual throttle body set-up is one of those ideas. However, before we get into that let's take a look at the car and groundwork that Sasha is building on.

Project S2000: Part 24 - Bridgestone Potenza RE-71Rs and DIY Brake Ducts

by Khiem Dinh

In the last episode, I’d worn down the Nitto NT01 tires into slicks. Then I got a nail in one of the tires too. Obviously, it was time to get some new tires. Many of you have asked about my custom brake ducts which bolt to the front lower control arm. Well, I tried out a cheap DIY version along with finally getting around to making some rear brake ducts.


 

"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.
