Gapless rings

04 Mach1 · 01-21-2006, 07:49 PM

Thinking of trying gapless rings on a forced induction motor any thought or has anyone tried a set.

I have known people to use them when spraying an engine but I have never talk to someone who ran them on a forced induction engine.

One issue may occur because of the increase cylinder temps, the rings may expand to much and won't have enough room to grow.

Perhaps Coupe may know someone who has ran them.

They actually overlap where they meet, so they can expand. You can use them, just make sure you have the right tension and setup.

I just prefer a good set of standard gapped rings with a little more tension for a stroker. But make sure a good machine shop gets the bores square and round...it will last longer and seal better, no matter the ring pkg..

I have just freshened up the bottom end . I had the machine shop end gap my rings but already having more blow by then what I want. I've heard of people using them on spray and had awesome luck, but haven't heard on force induction. Just thought I'd put the question out there.

Those who have used the gapless rings on nitrous and worked, is because they are lucky. A gaples ring would not let any excess fuel go thru the rings, which are prong to lipped the top ring land or the crown of the piston. Use a hell fire ring for you set up, because it produces a lot of heat, and any excess fuel will pass thru the second ring, which the way to set them up will be, example, top ring say 0.022" and the second ring about 26", why? So if it detonated it will not butt the top ring and the fuel and heat will pass thru the second ring quicker and less chance of rattleting the ring package and the piston. Been there done that. By the way, mine I gap at 0.032" at the top and second ring 0.034" and did not had any blow by even with the vacum pump disconected.

We have used Gapless rings in our Super Stock 427 Fairlane, years ago, and it was the slowest dayum motor we ever had, reasoning???? To much drag in the cylinders!!!...I would never used gapless rings

Again, it's all in how they're setup. Blowby is often not a result of the gap, but too low of tension. Remember the first 347 motors? Wanna know why they had blowby and smoke issues? Not the wristpin in the ring

...
It was because people used standard low-tension rings in them and they would give-out after a short time with the side-loading a 347 produces.

I am using Ackerly & Childs rings, like a hellfire. Pat Musi runs them.

So I need to run high-tension ring?

They suck.... good luck thats all I will say.
