Need input on my build and Piston Rings.
Need input on my build and Piston Rings. Well I have everything worked out on my build execpt what Pistons Rings to use exactly. I am going to use high tension oil rings and I am going to get the 2nd ring napier for better oil control for what is mostly a street car.
I planned on using Total Seal AP Stainless Steel top ring but do I use the gapless or file to fit? I have read many things about both and haven’t been able to conclude which would be best for me. Most of the posts talking about the differences are a few years old so I was hoping to start a new up to date read on them.
I know lots are running hellfire rings but have seen lots of people say they aren't for a street machine and don't last very long. People with these please chime in has for right now I am leaning towards Total Seal I believe.
My complete build outlined: Opinions welcomed.
APS Twin Turbo system with LG upgrades.
ERL built Superdeck 1 6 bolt heads with 1/2 inch studs, billet mains caps doweled with ARP studs, and brass Hydraulic Lifter Bushings.
Compstar Crank.
Compstar new H-I beam rods.
Wiseco Pistons -20cc.
Cloyes Hex adjustable LS2 IRL chain set. (Thanks Scoggin-Dickey)
LS2 timing chain dampner.
PatG cam. (Thanks Pat can’t wait to try it.)
Melling High psi oil pump.
Morel Link Bar Lifters.
Custom length pushrods.
Yella Terra 1.7 rocker arms.
TFS 235 heads.
ACL coated rod & main bearings.
Clevite cam bearings.
ATI harmonic balancer.
I think this covers everthing execpt for the rest of the power train which I am working on.

Whelp it is done, I ended up with file to fit total seal AP top ring with their second napier and high tension oil rings. By next April I hope to see if this sucker makes 1000rwhp or not.
I agree the GFX rings are good but I felt Total seal AP rings were better and after unloading this much cash I wanted to have the best for both power and the most bullet proof reliable ring as I don't want any oil burning issues what so ever. I will still have the GFX ring pack as a backup or in the future if I have problems I will pull it and swap them. I spoke with ERL and other well respected sponsors who build our engines for this power level and most all said total seal AP rings or hellfire. The AP ring won for me as I want the most longevity even though I expect to have scheduled freshening, has motors that live at this power level even on the street will require close attention and freshening.

As for hellfire, in 4.000 - 4.125 bore sizes they only make them 1.5, .043, or 1/16. They don't make a 1.2mm.
Wiseco pistons use a 1.2mm ring grove.
I'd use the GFX rings, file fit, i'd prefer the Total Seal gapless top rings for N/A. Theirs alot of expansion in the top ring for FI, we have ADRL XTF engine running .060" ring gaps, on the compression rings.

The GFX rings are made by NPR, basically the same ring as Total Seal AP.
