Project Defiant1: KA24DE Built Part DEUX! The Devil's Details!
By Justin Banner
Does building a successful engine require thousands of dollars? Not always! Sometimes picking up the throwaway engine is the key to saving on building a great engine! The KA24DE doesn't have the JDM factor, but it does offer more cubic inches, a stouter block, and a powerful aftermarket! Is the garage built KA24DE the key to Defiant1's 350 Crank Horsepower goal? How did I start? Read on to see "the Devil's Details!"
Project Evo X GSR- Testing the K&N Cold Air Intake
By Mike Kojima
We have a bunch of mods planned for Chris’s car, the first being a Typhoon cold air intake by K&N. The Intake worked so well that we decided to make it our first MotoIQ Certified Legit evaluation. The K&N Typhoon intake came with a dyno sheet that proudly proclaimed guaranteed power. Glancing at the dyno sheet we could see that the intake increased power by 20 hp near peak RPM. That seemed like a big gain so we had our concerns, this was a lot for just an intake, was it true or BS? We were going to find out with testing that was a little more in depth than just strapping the car to a dyno for a few quick pulls.
Our Project Nissan 350Z needs some new shoes. The stock Nissan alloy wheels had developed a crack rendering them unsafe and the worn generic tires that the car came with were on their last legs. It was time for an upgrade. Since we wanted a specific offset and width for this medium powered car we called upon Motegi Racing to provide us with a set of their TrakLite wheels.
Project Infiniti G20 Racecar: More Power!
By Steve Rockwood
Road racing is a thrill that has few equals in the wide world of wheels. Drag racing, unless you're talking nitro cars, is a thrill that quickly loses its lustre. Losing a drag race while road racing, however, is an exercise in abject frustration. Nothing will make you hate your car more than nailing that apex and throttle point perfectly to extract every ounce of momentum coming out of the corner, only to watch your opponent sail right past you on a long straightaway and park it in front of you in the next corner. Project G20 Racecar's tired engine, with over 130,000 miles on it, was destined to only let us down. We needed to fix it.
Project: Fried Turkey
MotoIQ Staff Report
Well, the holiday season is upon us and we decided we were going to cook something MotoIQ style which means it has to be technical and dangerous. What a better thing to cook than a fried turkey. Frying a turkey gets the job done in only 45 minutes and leaves you with a succulent and tasty bird with very little hassle and an easy clean up.
Project Miatabusa Part 12: Why You Can't Make Aluminum Exhausts... And Why I Did It Anyway
by Dave Coleman
From exhaust port to tailpipe, project Miatabusa's exhaust system fabrication has stretched well over a year and has followed a circular evolution from brilliant hack job, to exotic race tech, and back to brilliant hack job. From custom-fabricated race header, to a lightweight aluminum tail section, to scavenged RX-8 silencers and hangers made from an S13 power steering cooler, the exhaust system is as awesomely eclectic as project Miatabusa itself.
Project Honda EJ Civic, Footwork by Enkei and Nitto
Our project Civic has been getting a lot of attention in the suspension department and we had to make sure we upgraded our wheels and tires to something more aggressive to take advantage of our chassis work.
What would you think of a clean green car with the fuel efficiency of a hybrid, the performance of a relatively peppy gasoline engine and without the lifecycle costs to the environment of its battery pack? The car would be cheap to operate and relatively exciting to drive. Would you buy one if you could? If this sounds like you next car purchase, this technology is coming just around the corner in the form of Mazda’s new diesel technology called Skyactiv D.
Tested: Fluke Thermal Imager
Heat, it's a quantity we have to deal with in motorsports yet we often don't have a clear picture of it. Thermal management is critical to performance and reliability of any race vehicle; everything from brake fluid temperatures, to rear differential temperatures, to making sure hot parts in the engine bay don’t melt other components. One tool that can be used in product development and race track setup is a thermal imager. I had access to a Fluke Ti32 thermal imager and put it to use.
