Project Evo X, Testing The AMS "Widemouth" Downpipe!

By Mike Kojima

Since we opened up the back part of our exhaust with Greddy’s 85mm in diameter RS catback exhaust system, it was natural to next look for a better downpipe.  After evaluating what was on the market, we decided to use the AMS Wide Mouth because of several unique design features which we felt made it stand out above the rest.

Project Evo X GSR- Testing the K&N Cold Air Intake By Mike Kojima We have a bunch of mods planned for Chris’s car, the first being a Typhoon cold air intake by K&N. The Intake worked so well that we decided to make it our first MotoIQ Certified Legit evaluation. The K&N Typhoon intake came with a dyno sheet that proudly proclaimed guaranteed power. Glancing at the dyno sheet we could see that the intake increased power by 20 hp near peak RPM. That seemed like a big gain so we had our concerns, this was a lot for just an intake, was it true or BS? We were going to find out with testing that was a little more in depth than just strapping the car to a dyno for a few quick pulls.

Project EVO X, Keeping the SST Transmission and the engine oil cool!

By Mike Kojima

In the last editions of Project EVO X we worked to get our car's handling and stopping power up to world class standards and eagerly attended our first track event.  However we were really disappointed when our car went tilt after just a few laps at Streets of Willow Raceway.  When the SST dual clutch transmission in the EVO X MR gets too hot the engine's ECU automatically makes moves to protect the transmission and the car goes into limp mode killing all measures of speed until the temps drop.  In our hot Southern California climate, this happens so fast that it’s a frustrating experience and probably not good for the transmission either.

10 Fastest Cars of the World Time Attack Challenge Pro Class

by Eric Hsu

Now that the dust has settled from WTAC 2011 itself and the thrashing to prepare in the weeks prior to the event, I'm going to attempt to do an overview of the 10 fastest cars @ WTAC 2011. It seems there was plenty of coverage of the event and the cars on sites, blogs, picture hosting sites, etc. but nowhere could I find a summary of the 10 fastest cars in one place. Looking to build or bring a car to the WTAC 2012 Pro class? Look no further because this is your guide to your competition.

World Time Attack Challenge 2011 Pro Class Controversies

by Eric Hsu

The Yokohama World Time Attack Challenge (WTAC) 2011 was a massive success for the promoters, competitors, fans, sponsors, and vendors alike. Ian, Nathan, Kyle, the announcers, and the volunteers who all make up the World Time Attack Challenge and Superlap Australia successfully put on the best damn Time Attack event anywhere in the world to date! But there were some controversies and I attempt to clear them up here.

Sierra Sierra EVO Pre-WTAC 2011 Update

by Eric Hsu

The World Time Attack Challenge is coming up pretty fast next week on August 5 and 6. There have been some changes made to the EVO since winning the 2010 Source Interlink Superlap Battle final at Buttonwillow, but we've been pretty quiet about updates mostly because we've all been pretty busy concentrating on other things. Mike, Jet, Richard, and Ron have been able to squeeze in some work between the Ferrari races and I've been able to get up to Sierra Sierra a couple times for some engine testing in between my 900 other tasks and travels. The results are pretty cool I think considering what little time we've been able to spend on the EVO. Will the changes be enough to fend off the new domestic Australian and Japanese competitors? I sure as hell hope so. Pictures are inside after the jump.

Mitsubishi Owners Day 2011

by Eric Hsu

The USA's biggest meet of Mitsubishi cars in North America was this past Saturday. There were plenty of vendors, plenty of people, and of course Mitsubishis galore. The good thing about MOD 2011 is that there were plenty of modified cars which I thought resulted in the best MOD to date. Compared to say for example, MOD 2007, there were far less rows of stock Mitsubishis. Pictures inside.

Professionally Awesome - A look inside Professional Awesome's EVO VII Street Class Time Attack Challenger

By Mike Kojima

We first spotted Team Professional Awesome's EVO VII at last year's Redline Time Attack at Cal Speedway.  To be honest, it was not the car that first attracted us but the name of the team.  After looking the car over, we knew at once that this was a well constructed and balanced car.
