It Can Do A 9.9-Second Quarter Mile And Loves To Time Attack - And Get This: It's Just Warming UpWhat do you do when you have already built and successfully competed with what is quite possibly the most powerful Mitsubishi Evo the world has ever seen? Simple, really: Start from scratch and build another one-except with this one, you make it even lighter, better and faster. And that's exactly what Clive Seddon, the respected Evo guru from England-based RC Developments, has done.
His old Evo VI had been around for a couple of years now, with its highlights being 980 bhp during testing and 930 bhp in full public view, reaching 199 mph in 1.25 miles and winning two rounds of the 2006 Time Attack series, but it was starting to show its age and a replacement weapon was urgently needed for the '07 season. It would be a tough act to follow. "It's based on another Evo VI. We asked ourselves which is the best shell for this type of project and then picked the lightest and best looking, which is the Evo VI RS. It was an easy decision," explained Clive. He points out that it's hard to make a later version look as aggressive without a lot of bodywork changes. OK-this has got different bumpers, hood, skirts, rear end and a huge spoiler-but it's basically still an Evo VI at heart.
A shell was sourced and imported from Japan. When it arrived, it had already had some seam welding, but it was chemically dipped, blasted and stripped of any excess weight. It was then shipped to one of the UK's leading rollcage experts to custom-build a FIA-approved cage. This is possibly the most comprehensive cage ever fitted to an Evo. It's been totally made to measure without compromise and with no joining plates. The chassis is so stiff it doesn't even need a strut brace, yet the whole shell is light enough to be lifted by two people.
"It's a fantastic bit of fabrication, second to none," Clive proudly points out. "It hugs every corner with no spreader plates needed to make it reach pillars. It fits exactly where it should." Clive, aided by Colin Kitchen, an experienced rally car builder, then spent ages removing any unwanted studs and filling every hole, which was no longer required to make the engine and shell very neat and tidy. "There wasn't a single hole we needed to drill after the shell was painted," Clive confirmed. And that color? It's called Glasurit Translucent Yellow, and it's the same color used on police cars and other emergency vehicles for maximum visibility so other road users can see them coming and move out the way. No doubt a handy side effect on a race track!
Suspension is taken care of with an Evo IX TEIN Super Racing setup with a few modifications, such as the Evo IX hubs and lower wishbones, while the brakes are AP Racing Touring car spec, which, might we add, don't come cheap at $3,600 per caliper. "We had to dial most of the brakes away from the back," explained Clive. "Even with the radiator, water and fuel pumps moved [to the back] it's still so light and it kept locking up. Rather than move the fuel tank to the back, we kept ours in its normal place but replaced the standard ones with two fabricated aluminum tanks." And what does he pump into those tanks? "Anything from normal pump fuel, which I use on the road-yes, it's still road legal-right up to methanol, which we use on the track," he replied.
