2004 Ford Cobra - Clean And Mean
A past King of the Street competitor, Jake's Cobra is a mechanical marvel. Jake runs a dual fuel system on his twin-turbocharged car, switching from 87-octane to E85 under boost. Knowing E85 was available back home in Dallas gave Kevin the idea to make the switch to corn. At that time, E85 was new to the Dallas market, no one in the area had any expertise with corn. Luckily, Kevin does his own tuning, so he decided to give it a shot and see what happened.
E85 requires upgraded fuel system components. Although Kevin had already made fuel system improvements, it takes more E85 volume compared to gas. Therefore, he swapped the existing 60-lb/hr injectors for FRPP 80-lb/hr units and hit the street. "I ran out of fuel at 6,000 rpm while datalogging, so I decided to add a Kenne Bell Boost-a-Pump," Kevin says. He bumped up base fuel pressure to 50 psi and made another run around the block. With the larger injectors, Boost-a-Pump, and increased fuel pressure, Kevin was able to run it up to 6,600 rpm with room to spare.
With the E85 conversion sorted out, Kevin has been able to help others with their own conversions. E85 conversions have become so popular, website SVTPerformance.com started a new section catering to the E85 crowdùThe Distillery, for alternative fuels. "I was quickly nominated to become Moderator, which I accepted and continue to help people to this day," Kevin says. He has also written several how-to threads, but strangely enough, his most popular has been How to Polish Your Exhaust. We suppose everyone has a different version of "simple."
Anyway, Kevin's goal for his Cobra is to keep it simple. "Clean, tasteful mods with lots of torque and power, and stock driveability. That's exactly what the car is."
