i dont work for this company nor am i making any money by telling you about this product but i do believe in this proven product and have seen the results. if you want to polish the inside of your intake try this web site out. http://www.extrudehone.com/automotiveoem.html they take a gritty putty type substance and push it through the intake at a high pressure and this removes all of the burs and imperfections inside of the intake. by doing this you will increase the intake flow of air into your engine and it WILL increase horsepower. any higher volume of air mixed with gasoline will produce more horsepower. this is how a supercharger works kinda on a car but a supercharger also puts higher pressure and a larger volume of air to do the same job with greater horsepower capabilities. also by doing this to your intake it will also help lowering your emissions and increase horsepower. read this link and you will see. http://www.extrudehone.com/automotiveaftr.html i believe the delorean will benefit by this and also you will never know this has been done to your car unless you take the intake manifold off and look inside. i hopes this helps you all and if anybody wants to help me i have a 1992 supercharged mustang gt for trade for a delorean if anybody is interested. mark ionicdesign@xxxx
