BlackPantherSVT & warmonger...

Thanks for the info. I am always hesitant to "alter" stuff, especially expensive stuff. I have studied the backing plate carefully and believe I could reproduce one if necessary, including the little gap at the top (so many details). I believe I might try (when I do) a different avenue...I think a hole at the end of the venturi tube (in the backing plate) and possibly a short extension tube fitted and butting the venturi would produce the same effect and would be easier to reverse if necessary. While I had it out the last time I removed some heavy casting flashing in the airstream, I think that was good for 5-10 HP for sure...I thought I actually felt a difference! laugh O/T...I have sent money for a DMD to Terry. I think the jury has returned a favorable verdict for the DMD! I hope that will extend the life of "my little darling" as my wife is fond of calling her.
I wish there were some way of attaching some vib pickups to the side of the block to quantify any improvement. I'm sure, however, if, as reported, you can actually hear and feel a reduction in NHV in the seat of your pants...it must be better.
Anyone thought of a way to move the knock sensor or attach another one to the bottom end and re/wire it to give us vib data? It is nothing more than a vib p/u anyway. Wish I were smarter instead of just wiser (read older) laugh

Thanks again...Ed
