Just went for a rip on sled. With the 48/36 helix the sled pulls the same top RPM (8500) at 92 MPH on speedo, slightly faster than before. This is with the same weight in primary as before, (my weights have not came in the mail yet) So If i add weight as mr viper suggests wont this pull my rpm down? I think I want to be 8500-8700.
