KW Suspensions New Coil Over System for Nissan's 300ZX!

by Mike Kojima

KW has been looking at their product line up and has made a decision to start adding some applications for some of the classic Japanese exotics from the Japanese supercar heyday of the early to mid 90’s. KW has already come up with coilovers for the MK IV Supra and the NSX. The FD RX-7 is on the R&D schedule and we helped with the R&D for the latest Japanese classic addition, the Nissan Z32 300ZX.

Testing Fastbrakes' Bigger Brake Kit

By Mike Kojima

Fastbrakes is an Arizona company whose claim to fame is making affordable brake upgrade kits for many cars and having applications for niche models like the Nissan Sentra SE-R.  Since some of us race SE-Rs as they are a cheap and sturdy platform, we have a lot of experience with Fastbrakes' upgrade kits for the car.

AEM Water Injection Monitor Part 2: Catching Our Mistakes and Upgrading Our Water Injection System

By Mike Kojima

Over the past few months in-between other projects we have been tinkering around with AEM’s water methanol injection kit on our in-house Evo IX project car.  You can read about the kit here.   A few weeks ago we installed AEM’s new injection monitoring system which you can read about here.

Project Lexus IS-F Part 1:  We Test the K&N Typhoon High Flow Air Intake

By Mike Kojima

When our friends at K&N heard that we had gotten an IS-F, they got excited and insisted that we try out their Typhoon high flow air intake system as they claimed that they had gotten excellent results in their testing.

We Test Synapse Engineering's Synchronic Blow Off Valve and DV Diverter Valve

By Mike Kojima

We have been friends with Synapse Engineering's chief engineer Peter Medina for a long time, since before he started the company and even before he had the ideas that launched its product line.  Many years ago Peter came up with an original twist for pneumatic controlled devices, a piston actuated control valve.  Not just any piston actuated control valve either, Peter's valve had an actuator piston with two substrates, basically two individual pistons coaxially divided on one piston head, basically a stepped piston.


AEM Water/Methanol Failsafe Device Evaluation

By Mike Kojima

We are very familiar with water and water/methanol injection; many years ago, we were one of the first to tune with modern water injection systems and took advantage of water's ability to inhibit detonation and provide charge cooling in forced induction engines.  With water you can run more timing, more boost, leaner air fuel mixtures, a combination of all three or just use water to gain a measure of safety and to control engine temperatures for track use.

In a Time Attack car, the brake system is just as critical for a winning car as the engine.  The same is true for a street car but under differing parameters.  A successful race car has to slow down rapidly and repeatedly from high speeds. A street car has to do the same but for 100,000 miles with little maintenance.


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. 






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
