                   Former M.M.I. Engine and Rebuild & Performance Instructor
                          " CERTIFIED" A.S.E. MASTER AUTOMOTIVE MACHINIST

                   

                                 ALSO  Installers of:
                   TTS Master Tune For Harley Davidson

                         THOMPSON SUPERCHARGERS
                                  
                  NO BRAG JUST FACT This is Bolt in POWER
               This Dyno Graph done Memorial Weekend 2014
This graph utilized a "stock" 2014 103" with a TTS Master tune
The two graphs illustrate our BW-55 Which was used for the Buffalo Chip Bike build with Terry Components in 2012 and our BW-47 cam and how similar they are in making power
                    "remember this engine is Bone stock"
         "Air Cooled"     "with the catalytic converters in place" !
Notice the run starts at 1500 RPM and it is a Fifth gear roll on.
Our cams work between 2000 and 4500 rpm and pull to 5500 rpm.
            Knowing that revving your engine beyond 5800 the                       flywheel starts to spread do to the crank-pin bending
   remember it is a hollow crank pin! and it will flex welded or not.
Our Camshafts make great power with out the extra thousands.
                This one graph can be compared to all of
                      various  other Harley cam sellers
                                 
   This Dyno graph in is it original state with no doctoring done!!!
        AS a Reminder We do are own Camshaft design work.                        Note; The addition of a good exhaust system free flow air 
                  cleaner will enhance these dyno figures
                        with out doctoring up the graph.
