I have both hotsides for my VIII. I'm going to be fabing my own divorced o2 dump but I don't know which hotwire will be better. I know most say single flapper, I just want some input from anyone who has compared them. Thanks guys.

 

Any information??

 

Surprised there hasn't been any help.

 

I've heard the same on the single flapper. I can't see there being a huge difference so just mod that one.

 

In the dual flapper design the sealing between flapper and housing isn't always perfect, as in the single flapper.

 

Thanks for the advice!
