Caffeine and Octane - Atlanta, GA

by Brandon Campbell

Welcome to the Caffeine and Octane show.  This show started a few years ago with just 4 cars and has since grown to an average crowd of ~800 cars.  That is, ~800 cars of every shape, size, demographic, make, model and persuasion.  


Redline Time Attack Round 1

Redline Time Attack Round 1 – Buttonwillow Raceway

by Justin Banner

Buttonwillow Raceway, a track synonymous with Time Attack in North America. With its multiple configurations, it's a favorite among track enthusiasts as well. So, there couldn't be a more fitting place to hold the first round of the Redline Time Attack Series than this legendary track. What records would fall? You'll have to read on to find out!


Project 350Z - Finding More Power with MotorDyne Engineering

by Mike Kojima

In looking for more low hanging horsepower fruit for Project 350Z, we decided to try an intake manifold plenum spacer from MotorDyne Engineering.  The 350Z's VQ35DE engine has a very thin intake manifold plenum that slopes toward the front of the engine to clear the low hood line.  Although this is good for styling, the engine would prefer more plenum volume and the flow to the front most cylinders is somewhat choked off due to the low overhanging plenum wall.


Project E46 M3: Part 7 - Magnaflow vs. Corsa Cat-back Exhaust Systems

by Pablo Mazlumian

We install a Magnaflow system in hopes to quiet the car down a little further, given car's cat-delete setup.  Find out how the test goes--with video included!


Chicago Auto Show 2014

by Mark Zimmerman

The Midwest has had a crushing winter of storms, making it tough to do anything car related unless you have a nice heated shop or love plowing snow. This made the Chicago Auto Show a great car oasis in a fairly dull and snow filled winter. And while I was looking forward to checking out the new model year vehicles and seeing some show cars, I wasn’t prepared for just how much of an event this has become.  I tend to go to a car show every few years, and a bunch of vehicles in a huge convention center has become the norm. What I wasn’t ready for were all the events several of the automotive manufacturers put together to engage the public. So let’s see what caught my eye.

Kook’s Custom Headers might not be a household name in the tuner market, but they pride themselves as the pioneers in the stainless steel header revolution.  Their headers are trusted in some of the most demanding environments in the world, where every last horsepower matters.  Championship-winning NASCAR, NHRA, ADRL, IHRA, NMCA, NMRA, SCCA, and NASA teams go to Kook’s Headers for their decades of experience and their high quality state-of-the-art products.


Nerd’s Eye View: Honda R&D’s Acura ILX Endurance Racers

by Khiem Dinh

“Survive the 25” is the theme for many when racing the 25 Hours of Thunderhill. Team Honda Research West didn’t just survive, they conquered, taking first and fourth places with their pair of Acura ILXs in the E1 class. The class winning #27 car finished eighth overall which is a major achievement considering the serious hardware at the track. Building an endurance racer presents unique challenges which a sprint race car does not have to contend with. Follow along as we see what makes these cars and the THRW team winners.


Project NSX

Project NSX: Part 4 – We track test KW Suspension, Volk Wheels and Nitto Tires in Pursuit of a Track Record

by Billy Johnson

It’s been almost 5 years, but Project NSX is back!  While the turbo motor build has had some setbacks, we continue to move forward with the chassis of the car.  We made it out to Buttonwillow and broke some records with the help of a few new parts including KW Variant-3 Coilovers, Volk CE28 Wheels and Nitto NT05 tires.


Project Toyota Supra MKIV: Part 8 - Fuel and Engine Breather Systems!

by Pablo Mazlumian

With the engine almost fully complete and near-ready for start up, now's not the time to skimp!  Check out our new fuel and engine breather systems, ensuring we get the most out of this 2JZ!


TESTED: Royal Purple Max Boost Octane Booster

by Mike Kojima

To be honest we were not big fans of octane boosters.  In the past, we have not been able to get good quantifiable results with them over the years. Older boosters ate up the fuel system or left weird deposits on the plugs and chamber. Engines that usually need higher octane are generally expensive so we have always just used racing fuel in them,  Pump gas with conservative tuning for street cars and race fuel for race cars.

Meanwhile, Royal Purple had been bugging us about testing some of their new Max Boost octane booster.  They told us that it would give us 3 points in octane for sure and burn clean.  Not being too enthusiastic about octane booster in general we let it sit around for about a month.


Project E90 M3: Part 2 - Macht Schnell Bypass Track Pipes and EAS 80mm Exhaust Tips

by Billy Johnson

We continue our difficult quest to extract more power from our S65 V8 without hurting the daily drivability of the car. Since cat-back exhausts don’t really make any power for the E9X M3 and since there really aren’t any aftermarket headers on the market because the equal-length factory headers are that good, the only real performance gain is in the removal of the stock cats. We test the Macht Schnell “Bypass Track Pipes” (Test Pipes) and European Auto Source 80mm exhaust tips to give our stock mufflers a sportier appearance to match the improved performance and sound that the Bypass Track Pipes should deliver.


Project 5.0 Mustang- Building the Perfect Wheel Set with HRE and Nitto Tire!

by Mike Kojima

Last time we saw Project Mustang, it was off getting some new suspension.  With much improved underpinnings the stock wheels and tires were pretty wimpy.  Our Mustang came with 255/40-19 tires on a 19x9 inch wheel from the factory, pretty small for a heavy and powerful car.  With an improved Whiteline and KW suspension setup we wanted wider and more grippy tires to exploit all that our highly adjustable suspension has to offer.  Well look out, HRE and Nitto are coming in to fix the situation, check it out!


TESTED: Toyo Proxes RR

by Steve Rockwood

Toyo has been a staple in the R-compound world ever since it introduced the RA1. Until now, they didn’t offer a true DOT dry weather track tire. With the Proxes RR, Toyo makes a run at this hotly contested field. We tested a set to find out if they succeeded.


Project Silvia’s Girlfriend: Part 3 - Making it Pretty

by Dave Coleman

It only takes a short glance at any car I’ve ever owned (or any house, or my closet…) to realize I’m the wrong person for this third step on Project Silvia’s Girlfriend. Nevertheless, Sarah wanted a car that was up to her borderline obsessive standards of cleanliness and perfection, so I had to do my best to at least look like I was trying to achieve that. I’ve seen lots of pretty cars before, and I have a reasonable theoretical grasp on how they got that way, so I considered myself up to the task… at least at the beginning.
