Project Nissan Sentra Spec-V Part 6: Modifying the Brake System 

Project Nissan Sentra Spec-V Part 6: Modifying the Brake System

By Mike Kojima

When we last left off working on Project Spec-V, we were modding our engine and suspension for maximum power and road holding. Since we have will now have power and cornering capability, we now turn our attention to the other important part of the performance trifecta, the brakes.

Project Miatabusa depowering the miata steering rack

Project Miatabusa Part 5 - De-powering the steering rack the right way

by Dave Coleman

That's right; this installment of Project Miatabusa has nothing to do with putting the engine in the car. This may be the only Miatabusa strory where I don't mention the 11,000 rpm redline at least 3 times. Don't get used to it.

KW Suspension Factory Tour

Industry Insider: KW Suspension Factory Tour, Part 1

By Mike Kojima, photos by Jeff Naeyaert

We were stoked when we got a call from KW Suspension asking if we would like to visit their facilities in Germany a few months ago.  We felt like how Charlie in "Charlie and the Chocolate Factory must have felt when he found that golden ticket for a tour of a wonderful place.  If you don't know who or what KW is, they are the makers of some of the best suspensions available for both the tuner and the professional racing market.

Annie Sam installs JWT SR cams in her SR20DE

Project Racer Part 8: Nissan SR20DE S4 Cams from Jim Wolf Technology

By Annie Sam

So what was the cherry on top of our Nissan SR20DE horsepower upgrades? S4HL Camshafts from Jim Wolf technology. What are cams? First, let’s start off with the term “cams”. Cams are actually the lobes of the entire assembly, which is more formally known as the camshaft. But, for this article, we’ll stick to calling them cams, as that is the casual term for the part. So, let’s give a little introduction on the basics of cams.

Project Subaru STI Koyo Radiator

Project Gen 3 Subaru STI: Keeping it Cool with Koyo

By Mike Kojima

While awaiting the development of some ARK parts for our Project 3rd generation STI we decided to prep the cooling system in anticipation of the future installation of power parts.  Turbo cars run hot and when being track driven most have problems staying cool, especially on our Southern California tracks which are mostly located in the desert.  We turned to Koyo Cooling systems for one of their race radiators for our car.

Project WRX STI Brake System Upgrade

Project Subaru WRX STi Part 4: Brake System Upgrades

By Mike Kojima

The old engineers joke that “speed doesn’t kill, rapid deceleration does” applies to all vehicles capable of attaining dangerous velocities.  Since we have been concentrating on improving project STi’s acceleration and handling, we have definitely achieved the ability to reach deadly velocity on the track.  In our first foray onto the grounds of Willow Springs raceway we noted that perhaps we were starting to drive beyond the capabilities of the stock brakes due to the higher speeds that we were able to attain on the straights.

Ask Sarah: I Need More Track Time From My Water Injection System!

By Sarah Forst

I have a 1996 Mazda Miata with a Jackson Racing MP45 supercharger and an ECU controlled Aquamist water/methanol injection system.  The water tank I use is about 3/4 gallon in size, so when I fill it up with straight windshield washer fluid (no additives, just water and methanol) I'm running the tank dry well before my 30 min. track session is complete.

Mike Kojima Revenge of the Nerd 

 

By Mike Kojima

My involvement this year supporting Dai Yoshihara and James Deane with Falken Motorsports in Formula D drifting has been a wild ride.  It was a very interesting learning experience as I finally discovered what the dynamics of a really good drift car are and how to set up the chassis to deliver the performance a driver needs to do his job.  Modern Pro drifting is probably the greatest challenge for chassis set up out of any sedan based motorsport and the SPD Metalworks crew works pretty hard to get the car just right for any given course.

Conrad Grunewald camaro drift car

Bitchin Camaro: A look inside Conrad Grunewald's pro drift car 

By Mike Kojima

Unlike the Song by the Dead Milkmen, Conrad Grunewald's Hankook Tire 2010 Formula D pro drift car really is a Bitchin' Camaro.  Conrad like many top pro drifters comes from a road racing background.  He won the 2002 Skip Barber Mid West Championship with further success in Grand Am cup and Rolex GT racing before starting his career in Formula D.  We first ran into Conrad when he was the driver of the Technosquare built Tanaka Racing Z06 C5 Corvette drift car.

Chevy LS3 E-ROD crate engine

Project V8 RX-7: Part 2 - Inside the GM LS-3 E-ROD Crate Engine

By Mike Kojima
 
Hybridnoun- the offspring of two animals or plants of different breeds, varieties, species, or genera, esp. as produced through human manipulation for specific genetic characteristics.
 
In what was nearly a generation ago, a fire was started in the Sport Compact performance market. Some guys on the west coast started dropping DOHC B series engines from the Acura Integra and H series engines from the Prelude in to the smaller Civic, dumping out the SOHC D series econo motor. The creation was called a Hybrid and in the smaller lighter Civic the bigger engines produced amazing for the time performance and launched a huge industry that for awhile dominated the modification scene creating a lifestyle of its own. Import Performance. This generation was rooted firmly against anything domestic. Domestic offerings were considered unrefined, unreliable, unsophisticated and redneck.

Suck Squish Bang Blow part 5 Avoidance of Detonation

By Mike Kojima


Detonation is perhaps the deadliest sin you can inflict upon your motor.  It is usually caused by gluttony, another bad sin, gluttony for more power. Detonation is the result of going too far in the quest for power.  Pushing things to the limit when eking the last bit out, too far for your fuel's octane, too far for your fuel system flow capacity, too much heat for your cooling system to dissipate, the list goes on and on.  All of these can lead to a quick end to your motor. Really bad detonation can destroy any engine very quickly, about the only way quicker would be to dump out your oil while it's running full tilt.

The Ultimate Handling Guide Part V: The One Unforgivable Sin, Overlowering Your Car

By Mike Kojima

I am not Jesus so I don't have to forgive you if you mess things up when setting up your car. I am talking about sin, pure dumb unforgivable sin. No it's not the one that’s talked about in the New Testament that gives clergy fits to explain to lay people, its a big mistake, one that nearly all enthusiasts are unknowingly guilty of that is the most common mistake when modifying a car's suspension.  It’s a sin which so thoroughly screws up handling that it gives engineers fits when trying to explain why this is so to automotive enthusiasts.

Project Aprilia SR50 more power!

100 MPG Madness, Project Aprilia SR50 Part 5- More Power!

By Mike Kojima

We have brought our high tech Aprilia SR50 scooter from a fairly low powered urban runabout,  whose direct injection stratified charge 50cc two stroke was designed as much for greenness as for performance to a practical suburban commuter whose acceleration and 55 mph top speed are fast enough for serious riding in cut and thrust morning commuter traffic.

Besides its lavish brothels where you can legally get some uh diversions from racing, Pahrump Nevada is known for its state of the art track: Spring Mountain Raceway. We are getting to know our new Traqmate GPS data acquisition system a little better and got to use it again at Redline Time Attack's stop at Spring Mountain.

Inside ACT clutches

Industry Insider: A Look Inside ACT clutches

By Mike Kojima, photos by Jeff Naeyaert


We have been familiar with the ACT clutch line for many years.  One of the race cars in the MotoIQ stable has been running an ACT clutch for the last 7 years which is probably over 20,000 racing miles with no problems at all.  This is real racing mileage on a track, punishing use probably 5 times tougher than street driving. Perhaps the motorsport that is the hardest on clutches is drifting. Our friends on the Formula D circuit Joon Mang and Tanner Foust use off the shelf ACT clutches in the brutal, abusive clutch kicking world of Pro Drifting. For street use, ACT clutches are known to be great at holding torque with good smoothness and light pedal effort.

VIDEO: Dai Yoshihara helps us test the ContourHD and Traqmate GPS Data Acquisition System!

MotoIQ Staff Report

We tried out our new ContourHD cameras and Traqmate GPS data acquisition system on Dai Yoshihara's Team Falken Chevy LS powered S13 drift car at Formula D in Vegas... Unfortunately for us, it was hot.  Really hot even in the Nevada night. The heat on track was causing problems with the car's electrical system, the rear mounted battery's electrolyte was boiling even with heat shielding! This was causing the vehicle's line voltage to fluctuate wildly and in an effort to reduce electrical load, we disconnected the system after just the first couple of Dai's practice runs when he was trying to familiarize himself with the deceivingly technical Las Vegas course
