1st off they arent teflon coated, they are powder coated, 2nd, i spray meth, just like everyone else does so whats the difference, its fuel. 3rd what about the carbed guys with the big blocks that use the draw through fuel system? same thing, roots blower, i was just wondering if anyone here has done it. some call it ghetto but i call it a cheap alternative and i know its not nearly as accurate as a tune but for the time being (broke) i think it could work. Alot of turbo guys are running similar and even in most supercharger kits they give you extra injector system to add the fuel.
