Their new Type-33F intercooler is a bolt-on front-mount kit that has 60% more core volume. It’s a tube and fin design with divided endtanks
It also saw more than a few off-track excursions and engine explosions. All hail the almighty engine fire.
5Zigen says that the nuts are made out of an A7075 aluminum alloy (5Zigen calls it Geralnium), giving the nuts low weight while retaining strength.
Held once a year, the invite-only Super Lap Battle time attack event is the VIP track day where lap records are always guaranteed to fall. This year was no different. Sierra Sierra Enterprises’ Lancer Evolution VIII officially beat the HKS Evo for the overall top time with a blistering 1:41.046.
Take a closer look at the Cusco All-Japan Gymkhana Championship Lancer Evolution. It’s immediately obvious that their style of gymkhana is different from ours. While ours is all about entertainment, big smoke, drifts, and staying sideways, the Japanese form looks like pure autocross with a couple smoke-less spin turns thrown in.
With larger air intake restrictors allowed, ACP’s Evo IX generated almost 600hp with a built engine and 114-octane equivalent ethanol racing fuel. ACP doesn’t make use of the special ethanol fuel during regular rally events
We speak with Andrew Comrie-Picard “ACP” about his Rally America championship efforts and then go on board with ACP’s 600hp Evo 9 in a dirt course outside Irwindale Speedway.
Mother Nature is actually out to puncture and flip your rally car but that’s just part of the fun. So, how come rally racing isn’t as big as NASCAR in the US?
Glenney has just raced the Targa Tasmania in the Mazda RX-8 SP turbo rally car. Now he’s at Eastern Creek Raceway, driving the Pulse Racing Lancer Evo 8, Subaru Impreza WRX STI, and GT Auto Garage Mazda RX-7.
Held at Eastern Creek Raceway, less than a half hour drive out of Sydney, the WTAC was one of the first international time attack events, drawing in competitors from the US, Australia, and Japan.
Faster on track than a Porsche 911 Turbo while using full tread, wet weather capable street tires. Once we play further with spring rates, alignment and other adjustments, we’ll be able to pick up even more speed. Simply. Badass.
AMS claims 650whp out of the 35R-equipped 2.3-liter engine. Lots of parts and surely you couldn’t it again for the same price, but is this car worth $125,000?
Like a good set of tires, drivetrain is an often-overlooked area of car tuning. Many obsess over blowers, exhausts and wheels but when it comes time to get that project buttoned up, the cheapest clutch kit is usually shoved in.
Joining together members of the auto industry in a laidback and casual environment, which is one part networking and two parts driving, the day was a sold out success. The range of companies present ran the entire gamut of the industry, with employees present from corporate giant Honda down to small racing shops.
Although they lacked the custom widebodies, insane engines, and roll cages of the upper classes, many of the Clubsprint cars were still well modified track machines. At any normal open track day, these cars would dominate.
Project Evo IX’s last track outing did not go well. On top of being outgunned power-wise in the Street AWD class (our 350whp stock turbo setup always is), we discovered that our rear limited-slip differential had given up the ghost.
We knew that we wouldn’t have the time or the budget to strap on a bigger turbo or a fancy carbon fiber rooftop before we left. We’d be facing 600whp monster Lancer Evos again with our daily driven 350whp (on race gas) street car. Not a problem for the constant underdog OR team, right?
Headed up by Koyama-san, formerly of JUN Auto, Koyama Racing has built this Lancer Evo X as their first demo car. Features a custom turbocharger setup, custom intake manifold, aero work and full chassis prep. Has been used in time attack and other track events.
The Yokohama Advan Neova tire displayed high grip and sharp steering feedback on track, especially through the very quick Turn 2 (average 87 mph) and Turn 8 (average 119 mph) areas.
