Revenge of the Nerd, Track Day Douche Bag VIDEO

By Mike Kojima

A lot of us at MotoIQ are driving instructors for NASA, Speedventures and other groups.  As instructors we get all kinds of students, some good, some bad.  This is a classic example of a typical type of bad student.  More inside....

The Ultimate Guide to Suspension and Handling Part IV: Reduce weight transfer

By Mike Kojima

Now that you have reduced body motion and improved steering response, and tuned out under or oversteer to improve the chassis balance, our next step is to reduce weight transfer. Weight transfer is the movement of weight from the inside to the outside wheels of a car under cornering.

Extreme Engine Tech: Jim Wolf Technology's Turbo Nissan QR25DE Powerhouse Part 2

By Mike Kojima

When we last left off on our QR25DE project, Jim Wolf Technology was well on the development path for our motor with new rods, pistons and the removal of the balance shafts.  JWT still had a few more tricks up their sleeves to help the motor make more power and to improve its reliability that we will get into in this installment.

Keep Testing Fun: Mike's Day Off!

By Mike Kojima

Bringing you MotoIQ is a pretty tough job, we generally work as much as 80 hours per week which involves writing, layout, photography and wrenching.  On top of that, I am a suspension consultant which keeps me busy traveling and working when I am not here.  We don't get much time off but we love our job and that helps.  We really like driving but we hardly every get a chance to actually drive!

Other stuff we do for fun!

Sarah Forst's Turbo Sentra

Sarah's Ride

By Annie Sam

If you have been a fan of  MotoIQ, you have probably been reading The Queen of Questions, Sarah Forst's tech column from day one. Our statistical tracking software has shown that Sarah's works are the most highly trafficked of all of our features.  So some of you are probably wondering, how did she get to know all of this stuff.  Well if you know Sarah, you understand that she is very thorough and loves to research things. She has a financial background and complicated analysis and number crunching are natural for her. She learned much about extreme tech from building up her own car many years ago, meeting some of the countries top Nissan tuners and becoming a master of tuning herself in the process.  Now Sarah has several cars in her arsenal ranging from a G20 winter beater to a G35 daily driver and a NX2000 track car but none are as interesting as her super Sentra.

Revenge of the Nerd:  My Mail Box and Other Funny Stuff

By Mike Kojima

So it looks like Jeff has too much time on his hands and has been hard at work making digitally enhanced unflattering images of me again.  I guess the point this time is not some sort of tech rant from me but to show what showed up in the mail at the palatial MotoIQ Headquarters.  Someone named Mr. Thumb has started up a group called NoFakeShit.org and since MotoIQ has always had an anti janky copy policy, Mr. Thumb has sent us a care package full of cool anti fakes stickers.  I especially like the one you could stick on someones car that is equipped with fake stuff.

Project Honda S2000 Stoptech big brake upgrade

Project Honda S2000 Part 3- Brakes that don't Break

By Khiem Dinh, Photos by Jeff Naeyaert

Although the Honda S2000 is one of our favorite all time cars, one of the parts we like the least about the car is the brake system.  Although they are perfectly adequate for street duty, the stock brakes do not match the excellent handling ability of the car and are not up to snuff for track day use. S2000s that are tracked heavily, especially on non-staggered setups running 245 or 255 width front tires, are prone to cracking front rotors.  The added traction from the wider front tires means more braking power and therefore more heat the front brakes must dissipate.  This added heat is simply beyond the capacity of the stock brakes’ design, leading to oft cracked rotors.

Top 10: World’s Fastest Time Attack Cars?

By Carter Jung

For my first-ever MotoIQ article, I’m going to delve deep Down Under and take you to the World Time Attack Challenge. The World Time Attack Challenge? You mean the time-attack event that popped off in Sydney, Australia? Didn’t that happen, like, in May? That would be a yes, yes, and another yes. Alright look, I’m used to the print cycle where two months is the standard operating procedure. Besides, you cheap Internet bastards don’t even pay for content, so go ahead, try and get a refund.

Performance Friction Brakes

Performance Friction, State of the Art Braking Systems

By Mike Kojima, photos by Jeff Naeyaert

Those in the know are very familiar with the Performance Friction company. Performance Friction brakes are found on most of the paddock at the highest levels of pro racing. IRL, NASCAR and ALMS teams go to Performance Friction as the brand of choice for their brake system and friction material needs.

Performance Friction is also a brand of choice in the tuner market. Many of the top Time Attack cars run Performance Friction pads and brake systems as well as a legion of club racers. Performance Friction pads are also a favorite among the staff at MotoIQ. We are enamored of the performance and consistency of the product.

WRC B-series Honda CRX

by Eric Hsu

Of course it really isn't a WRC Honda CRX, but it's the next best thing: a Honda CRX built by a WRC fabricator. It could very well be the world's cleanest and most functional CRX cage. Just several pics of a very nicely built CRX located in the UK.

Mechanix Wear kevlar sleeves and Team Issue Carbon-X gloves

No Burns! Mechanix Wear Team Issue Carbon-x Gloves and Kevlar Sleeves

By Mike Kojima

In the world of Pro Drifting crew people often are caught in the world of the 5 minute rule.  If a car is too damaged to continue, you can have 5 minutes to fix it.  If you cannot you are disqualified.  Under this pressure repairs have to be made quickly.  This means that you often have to work around components that are glowing hot and most of us have scars to prove this.  The same thing with pit stops in endurance racing, especially for chores like brake pad changes or working around exhaust components.  In the world of racing, there are often times where you can't wait for a part to cool down enough to work on.

Project 200SX - Track Ready?

By Wes Dumalski

It's no secret that driving your car at speed on a road course will bring to light all of the car's weaknesses. After sorting the motor and suspension we decided to take Project 200SX to a few track day events to put the car through its paces. While the car has proven dead reliable we certainly found its shortcomings.

Air fuel ratio and compression ratio explained

Suck, Squish, Bang, Blow part 3- Compression Ratio and Air Fuel Ratio

By Mike Kojima

In our last edition of our ongoing series on engine tuning and theory, we explained how the 4-stroke cycle works.  Now we are going to break down a couple of common and very important terms that you will hear all the time when discussing engines that you must understand if you are going to successfully tune or select parts for your motor.  This information can also help prevent you from getting ripped off by bogus speed shops.  This can also help prevent you from being steered wrong by SPE's, FFF's and other lameo guru types that inhabit various forums and online resources.
