I just got back from Chuckwalla Valley Raceway.  Since my last track day at Buttonwillow, I’ve added new tires, suspension, and camshafts.  My new Falken RT615Ks don’t just have more grip than the original RT615s, they have so much more grip.  I was pretty stoked to shave off 2 seconds from my best lap time with every passing session (6 seconds total).  Oh, and 255 up front and 235 in the rear is just win.

It’s also the first time I tried out my Toda Fightex Type-DA coilovers out on the track.  The best way to describe the Fightex is 1.) so easy to drive and 2.) so much more grip than my previous set of coilovers.

Stock Type-S cams made peak power at like 7000 RPMs.  When you heel toe into 3rd gear at 6000 RPMs with stock cams, the motor didn’t feel like it made any power.  Stock cams seem to give you couple thousand RPMs so you could just keep your foot down.  Toda A3 cams made a huge difference.  At every heel toe, the motor kept making “torque-y” power up to redline (and presumably beyond).  I was able to keep up with a lot of high horsepower cars (M3s, Evos, etc…) out of turns and on the main straights because of the A3 cams.  I met a professional Australian motorcycle racing driver who owned the below Mustang Boss 302.  He was pretty surprised how quick my car was and even more surprised when I told him my power output was around 250 HP.

Anyways, enough about me raving about my new mods and onto the pictures.

Hunting down a few cars.


A year back or so, Eric Hsu wrote an article on how Mishimoto radiators, thermostats, and radiator caps proved to be crap in motorsports. Mike Kojima also commented:

A few minutes later, one of my friends on his crew came up to me and said, “wow Eric was right”, he shall remain nameless because he is a well known industry guy/magazine writer. In his hand was a blown up Mishimoto radiator cap. It blew at the start of one of the runs and the coolant flash boiled resulting in the engine overheating and dying a violent and expensive death.

Around the same time (November ’09), I took a few pictures of the GT Motoring S2000 at a Redline Time Attack.  I’m not sure if the car was sponsored by Mishimoto or not.  Anyways, notice how it’s running a Mishimoto radiator but a JDM Billion radiator cap.  Shows you how much trust they have in Mishimoto products.

I’m not sure why people opt for Mishimoto radiators when Koyo aluminum radiators are reasonably priced (compared to ARC, Calsonic, etc…), quality, and proven itself in motorsports.  I see a ton of people in the show scene ditching their OEM radiators (probably made by Koyo or Calsonic) for questionable Mishimoto radiators so they can get “engine bay points”.  Personally, I would never ditch OEM products for products from questionable aftermarket performance companies, just to look cool.

Brad’s RX-7 @ Industry Track Day

This is Brad’s RX-7 at Mackin Industries’ Industry Track Day.  If he’s not at the Tokico booth, he’s usually with the Double D Garage’s lineup at car shows.  He’ll be at the Tokico booth at Spocom next month!

Here are a few comments from Brad:

A few pics from the Mackin Industry track day from Buttonwillow Raceway Park, Buttonwillow CA.
The car ran great all day long, nice cool coolant temps and air temps great response from the turbo very fun day.
The only hitch in the day was the last session where the tires lost grip and the brake fluid started to boil so I had to do alot of left foot pumping of the pedal so I had a
firm pedal going into the corners. no brakes and worn out tires made for a handful on the track but still a blast!
But those are easy fixes, new tires and flush the brake system and all is well. The car is in one piece and I’m already looking forward to the next track event at Cal Speedway in Augest for Mazfest.

Team Honda Research West

Spied this car at Buttonwillow and snapped a few pictures.

225/45R17 Hoosiers.  Looks like they swapped on Acura TL manual/Type-S brakes, which are really just OEM Brembos.  I wondered how they dealt with the proportioning valve?
