El Diablo's stock turbo, 130,000+ mi beast tamed on E85 with a Scott Davis Protune!
El Diablo's 2003 Lancer Evolution is one of North Georgia's baddest street machines. With a carefully selected group of modifications, Kevin's goal was to maximize the performance of his Evo while keeping the factory turbocharger in the mix of things for now. Amazingly, running trouble-free Kevin's 130,000 mile old 4g63 engine was running flawlessly, despite the high mileage.
In his latest set of modifications, Kevin opted for some unique products to enhance the performance of his Lancer. already set up with a ported throttle body and stock intake manifold, Kevin wanted to upgrade his camshafts to TOMEI 260 duration bump sticks with a lift of 11.5 mm. To complement the new camshafts Kevin opted to install matching TOMEI adjustable cam gears along with his HKS kevlar purple timing belt.
Along with these new modifications was also an upgrade in the engine programming department courtesy of Scott Davis from TTP-Engineering of Orlando, Florida. The advanced engine management programming plan was to implement speed density tuning, tephra mods V7 big maps with alternate switchable fuel maps for both 93 octane, as well as E85 ethanol. Scott also recommended ECU controlled boost management along with the safeguards he has implemented into the mapping.
Aesthetically, Kevin had some unique modifications such as lensless taillights and omission of the rear spoiler. In the place of the spoiler mounting holes in the trunk, lie black steel spikes giving his car is much attitude as its owner. Unfortunately, curiosity killed the cat and in determining whether the spikes were for real or not I quickly learned that yes they were real, and yes they were very sharp. LOL
Rounding out the rear of the car is a UK Evolution trunk badge and unique Evo nine JDM rear bumper cover in a single color rally red. Typically, these bumpers are painted two colors but in Kevin's case he wanted to be unique.
Onto the meat and potatoes, cabins. Lancer evolution with the TOMEI camshafts and Evo nine turbo with speed density tuning by Scott Davis ended up with a respectable 338 hp with 355 wheel torque at a safe boost level of 24 PSI. Once the pump gas tuning was completed, we moved on to the fun stuff. E85 ethanol was used to fill the tank after a short draining session of the remainder of the 93 octane from the tank. With the new alcohol-based , and domestically produced fuel running through the 1000cc injectors, scott Davis was able to bring the engine alive with the help of the new octane boost and more performance oriented ECU programming. The end result was an impressive 404 wheel horsepower with 395 foot-pounds of torque to the wheels.
We are not sure what the future holds for El Diablo, however we think a larger turbocharger is probably in the foreseeable future. Stay tuned…
