Gas Ported Top Ring?
 
Has anyone actually seen a gain from using these 2 piece, gas ported top rings vs Dyke or a good, backcut top ring?
Thanks,
Chris Hardy

I believe so. With the amount Total Seal charges for a set of rings with the ported spacers, I'm certain they have realized a significant gain to their bottom line. LOL

That is exactly what I saw. Zero gain in HP. And Total Seal making dividends. Thanks:)

Both .047 (1.2mm) gapless most engines depending on max RPM and .032 (.8mm) have shown gains over all the other top rings we have tried here

Hi Bub,
Were you keeping your end gaps extremely tight on the engines that you are comparing these gas ring to?
Thanks,
Chris
