   So that's a factory setup...it makes nearly as much HP as the 450 cubic   
   inch motor without having to boost the system to 40 pounds. Instead, it   
   uses a factory ignition system with only 8 pounds of boost, all on pump   
   gas (read 93 octane)...   
      
    TW> HOW did it do at 40 Psi Boost??   
      
   It'd do a lot better than that Ford motor could do.* Obviously, your ad is   
   intended to sell Denso spark plugs, to the unknowing, non-thinkers in the   
   crowd.   
      
   * A naturally-aspirated (14.7psi) LSX (454ci) GM engine makes 750 hp   
   without needing any boost...which tells me that the guy who is using twin   
   turbos to boost the compression ratio of that 450ci Ford engine, isn't   
   doing something right. It should be making 1200-plus hp...
