I was born in to auto mechanics and performance modifications. I was less than 4 weeks old and my dad had me on his chest while under his muscle car swapping transmissions. And its been a passion of mine ever since. I went to school for this, being awarded a degree and multiple certifications. Personally, I've had my hands in on 1 first of its kind build. But, with the extensive education I have, I see that gasoline motors are reaching their Performance and efficiency potential; There is not a hole lot more you can do that would be an innovation. Diesels on the other hand have been an exploding industry since 2000 and shows no sigh of slowing down. With rising fuel prices and the push for fuel efficiency, diesel motors dominate gas engines. A turbo diesel engine that is the same displacement of a turbo gas engine is going to produce similar power out puts while using 30% less fuel. NOTE: power production in the automotive world is torque, not horse power. Its not possible to measure horse power, as its a mathematical equation of torque; torque being a measurable force.
