Recently we had a customer purchase our Sport Compact Car Ultimate Street Car Challenge winning EVO X. The customer wanted to bump up the horsepower into the 700 range. Because this had never been done before, I was a bit skeptical that I could get it to work, and we had him settle on a low to mid 600whp number instead.
Mission Improbable

“Beat the GT-R around Streets in the blue Evo. I still want to take my kids to bassoon practice with it, though. And you know how I hate getting my hands dirty. I’m an ‘arrive-and-drive’ kind of guy. Get it right or pack your stuff, Pal.”
After taking a year off AMS Performance returns to Time Attack with a newly build Mitsubishi Lancer Evolution X. The car debuted last November at the Super Lap Battle Finals where it took second place in the street class. Over the winter the car has been transformed into a full unlimited race car and its set to compete in the Unlimited AWD class in the Redline Time Attack series.

ACP Rally Mitsubishi Evolution X powered by an AMS built 4b11 engine
ACP Rally Mitsubishi Lancer Evolution X
Rally driver Andrew “ACP” Comrie-Picard took a second-place finish at Round 2 of the Canadian Rally Championship over the weekend and is now set to return to U.S. competition in Pennsylvania in a few days.
Comrie-Picard and co-driver Robbie Durant took their new Mitsubishi Lancer Evolution X to the Rocky Mountain Rally, based in Calgary, Alberta, for the high-speed May 29-30 event.
“It was an intense two days of competition, especially with the gravel debut of the new car” said Comrie-Picard. “The 2009 Mitsubishi Lancer Evolution is a strong platform and we’re working to improve its performance with every event. The Evo X will be more and more competitive through the year.”
The new car is under development this season in Canada, while the team continues its aggressive campaign in their 2007 NOS Energy Mitsubishi Lancer Evolution IX south of the border.
In addition to the rally, the team welcomed key partners, including a number of local Yokohama Tire dealers, for ride-along sessions the day before the event – giving their supporters the ride of a lifetime on a gravel course east of Calgary.
Special thanks to Calgary’s Platinum Mitsubishi for hosting the team at the dealership during the contest.
The result brings the team into third overall in the Canadian championship. Subaru Rally Team Canada driver Pat Richard and Rockstar Energy’s Antoine L’Estage are tied for the lead – with one win and one DNF apiece after the opening two rounds.
“We had some luck on our side this weekend that allowed us to podium despite some inevitable teething trouble with the new car,” said Comrie-Picard. “It was an excellent learning event for us and now we know what we’ll be working on before the next Canadian round.”
Meanwhile, Comrie-Picard is narrowly in third-place overall after five rounds in the Rally America championship, behind Subaru Rally Team USA driver Travis Pastrana and Rockstar Energy’s Tanner Foust.
“The Susquehannock Trail Performance Rally is close to home for us and we know it well,” said Comrie-Picard. “We’re looking forward to resuming our US championship campaign – as well as facing off against some series newcomers.”
The event is expected to feature the American rally debut of Swedish World Rally competitors Patrik Sandell and Emil Axelsson, and Freestyle motocross champion Brian Deegan — winner of 11 X Games medals.
The Susquehannock Trail event has long been known as one of the most demanding events on the U.S. calendar. The 2009 running of the contest features a return to the popular two-day format, with a spectator-friendly daylight schedule and super special stages on each day.
Teams will take on over 100 miles of competitive stages this coming weekend (June 5-6) on a tricky course that’s fast-paced, yet technical. Narrow but very fast roads, with the potential for slick mud if wet, translate to plenty of challenges for competitors.

Puerto Rico is the jewel of the Caribbean. Known for sand, surf and rum, this US commonwealth is a vacation hot spot. But a lesser known fact about Puerto Rico is that drag racing reigns supreme. Blasting the quarter mile is still a favorite pastime for many Puerto Rican racing enthusiasts.
When Mitsubishi released the highly-anticipated Evolution X, Johnny Fargas was among the first in line to buy one. At the time, the Evo X was brand new and few performance parts were available. Undaunted, Fargas began his quest to take the Evo X to a higher level.
Breath Easier, Run Faster
The new 4B11T engine holds a great deal of promise. Fargas elected to build upon the unmodified longblock and explore its capabilities. The first step was to increase the capacity of the turbo system. Starting with the stock manifold, Artec ported the factory manifold to increase the volume of exhaust gas going to the turbine. Then the manifold received a ceramic-metallic coating by Turbo Coatings. This process keeps exhaust gas heat inside the manifold and ensures that the exhaust gases have the greatest velocity on the way to the turbine inlet. The stock TD05H turbocharger comes from the factory capable of handling 360 horsepower, with a ball-bearing cartridge and a titanium-aluminum alloy turbine wheel. Starting at the turbocharger, Fargas looked to his friends at Yiyito Turbo for assistance. The responsive turbo sacrifices top end power for a quick spool up; therefore to reduce the backpressure in the turbine, Yiyito Turbo ported the turbine housing. The increased volume allows for increased exhaust gas flow. From the turbine housing, Ultimate Racing’s stainless-steel downpipe channels spent gases to the AMS stainless-steel exhaust. On the compressor side, fresh air is drawn through an AMS cold-air intake system. Once compressed, the air charge flows through an AMS hard pipe en route to the AMS front-mount intercooler. The charge pipe brings the chilled air to the throttle body and intake manifold.
Powering Into The Tens
To supply additional fuel for the increased volume of air coming into the engine, a 255 lph in-tank fuel pump and an Aeromotive fuel-pressure regulator replaced the stock units. With the necessary volume of fuel available, the factory injectors received new duty-cycle instructions from the EcuTek-tuned factory ECU. A Hallman manual boost controller holds the boost steady at 32 psi as the remapped fuel and ignition curves help the 4B11T engine spin the drums of the Dynojet dynamometer. Through the AWD driveline, the Evo X generated 438 horsepower and a neck-snapping 453 lb-ft of torque.
Clamps And Rollers
Pushing the stock clutch to its limit, the decision was made to upgrade the driveline with an ACT heavy-duty clutch. Now able to efficiently turn the wheels, addressing traction issues became the next task. Adjustable BC coilovers featuring 8 kgf/mm springs in front and 6 kgf/mm springs in the rear now drop the CZ4A chassis. This more aggressive stance better prepared the Evo X for both the street and the strip. For the street, Advan RGII wheels in an 18×9-inch offering mounted with 265/35R18 Falken FK452 tires take their place in the wheel wells. When visiting the track, a lightweight set of Buddy Club P1 Racing SF 17×7-inch rollers equipped with Mickey Thompson 26×7-inch slicks ensure launch traction for quarter-mile sprints.
