Hey. I wanted to know if there is any noticable benifit from a velosity ram. Can they be any length or should they be a tuned length? I made one for my 66cc engine. I just made it look how i wanted it. Its a 25 degree slope and a 9/16 hole. It got a bit dented when it flew outta the lathe. I havnt started it up with it on yet.
