forced induction forum SUCKS!!!!
forced induction forum SUCKS!!!! thought that would get people in here to answer my question since no body responds to my questions.
would somebody please tell me what kind of rings and the gap to run in a blown motor. building a 5.3
Thanks

If it's around a 3.9 bore and you're going for I'll guess 500rwhp I would recommend 1/16 1/16 3/16 rings. Moly top, J-hook second, low tension oil. .021 gap top ring .023 gap second ring
Stay away from the Total Seal ZGS rings and the C&A gapless rings.

Re: forced induction forum SUCKS!!!! thank you it is so nice to get some usefull info. now as far as the gapless ring that are suposidly for super charging has any body heard any thing about them? suposidly the second ring is gapless instead of the first and they are made of better matterial than the orig gapless.
opinions please.
THANKS AGAIN FOR REPLYING

Re: forced induction forum SUCKS!!!! I would stay away from any of the gapless rings. They are a gimmick.
Yes they can show 0% on a leakdown test, but your piston sitting still in the bore isn't what I would call close to operating conditions.
The problem with the zero gap second ring is that pressure that gets by the first ring, must get by the second ring in order for both rings to stay sealed to the piston.
With the zero gap second ring, pressure gets by the top ring and can't get by the second, so the pressure between the rings unseats the top ring and causes it to flutter, and lose it's seal.
It's now common practice to gap the second ring larger than the top ring in order to lessen the chance of pressure buildup between the rings.
I have heard now that they started making a zero gap top ring. I have no experience with those (nor do I plan to), so I can't give you an opinion on them. Due to the construction of that type of ring I would be worried about durability though, especially being the top ring.

Re: forced induction forum SUCKS!!!! `yep, I 100% agree with INTMD8.
I tried the gapless rings about 7 months ago. Had oil control problems with them and decided to pull the motor and throw them in the garbage.. Would never use them again.
Low leakdown % means squat. You could put a rubber o-ring on the piston and show 0 leakdown.
Gapless 2nd rings totally contradict current theory.The new gapless top ring may work much better.
I use conventional rings now. Ductile moly top, cast 2nd and standard tension oil.
I run .025" top, and .028" 2nd in a 3.905 bore.
Piston to wall clearance is at .005".
Works very well.

I used the total seal file fit rings in my turbo buildup. Don't remember what gaps I filed them to though. Got the info from Nick Agostino. It was very close to what was recommended by Total Seal in the instructions.

Re: forced induction forum SUCKS!!!! thanks for the info i should of got rings with my je pistons but didnt and the person i orderd the pistons from ordered gapless rings. steve is suppost to be checking around on them but i have heard so much bad stuff about them i dont think i want to use them. after all i have spent tons of money building this motor and the last thing i need to do is pull it because some cheesey *** rings make it smoke. thanks for your coments just seeing what experiences people have had with these rings.
thanks
thanks
