REFLECTOR: In pursuit of speed

[steve korney]

I wouldn't go to 11:1 compression ratio..... Long term, the engine runs to rough and shakes a lot... Hard on everything...

    The CS prop by itself won't get you any more speed. 

    

    The combination of turbo charging a and CS prop would.

    

    A much "cheaper and modern" alternative would be to install a set of
    high compression pistons, say 11-1 into you IO360.  With balanced
    injectors and electronic ignition and high compression pistons, that
    would be a intriguing combination.

        Geoff,
        

          
        Scott B. is right. If
            you are in to that much time and money for speed, I would
            ditch that climb fix pitch prop,  and go constant speed. If
            that doesn't do it for you then Turbo charge. You will find
            your speed at altitude!

              Guys,
                

                
                I contacted Clinton at Custom Aircraft Parts.
                   Turns out he was just going through his warehouse a
                  week ago and came across a set of tack welded pipes
                  for a IO-360 Velocity.  He sent me pics, and it looks
                  like they will work.  So, I may have a set pretty
                  quick.
                

                
                Does anyone have any experience swapping wings b/w
                  Velocities?  If I could find a set of normal SE wings
                  and swap out my 173 wings?  Does anyone have a set of
                  SE wings kicking around?  173 wings are essentially XL
                  wings, right?  If so, perhaps there's someone out
                  there building an XL who would like a set of fully
                  completed wings and I could just buy a set of fast
                  build wings from the factory.  If I got 15kts out of
                  swapping wings, I'd do it.
                

                
                Geoff
