Re: .031" Dykes or .043" Rings ?
 

[QUOTE=RPinoski1;117276].043 With no lateral gas ports. Lateral ports create a vacuum leak on the intake stroke so now not the way to go anymore.
Napier second ring with twice the end gap as the top ring. Eliminates top ring flutter.
Remember: This type of ring as with all secong rings is for oil control only hence the larger end gap.

Vacuum leak on the intake stroke, not so... look at the top ring after run and you will see wear mark on the bottom inside whare it seals on the intake stroke... also second ring, especially napier not only controls oil but its reverse taper face aids the intake charge...

.043 pro series .155 rings with vertical gas ports would be far better than the dykes and proper ring clearance would be a key factor also. There are also diamond finished rings which would be a great option. There are some other options that are popular on these piston I can explain to you if you want to call me. take care 316-775-7771

Well Patterson, looks like we are in agreeance as far as .043 with lateral gas ports, regardless of radial wall over Dykes ... you take care also...

Re: .031" Dykes or .043" Rings ?
 

My LT-1 had 1/16" top ring grooves and I used std. top rings with cutback seconds and very low tension oils......I have used the .031" dykes with spacers in a 5/64" groove if I remember right in my 350/255 back in the '90's......Do the .043" rings go in a 1/16" groove with spacers.....and the rings are where the gas port grooves are cut ? .......the spacer would be pretty thin and I have no experience or knowledge of the gas ported ring setup. Just curious about this and I might need the knowledge for a future Stocker engine project for someone else........

Re: .031" Dykes or .043" Rings ?
 

Well Patterson and Bub, i too agree with you guys,,,,Total Seal now can supply you with Gas Ported spacers to go with the .043 Top Ring. I haven't seen this metioned but, it is illegal to machine Lateral Gas Ports in a Stocker piston,,,sooooooo!!!!!!!!!!!! The .043 Diamond Cut ring or 1/16 or 5/64 Diamond cut is the way to go but, a little pricey!

I'm suprised at the poll resuslts. Didnt know anybody still used dykes rings.

Re: .031" Dykes or .043" Rings ?

Re: .031" Dykes or .043" Rings ?
 

What about the .7 & .8 mm rings & 2 mm oil rings for engines in the 8,000-10,000 rpm range?
