I have a good friend that is a circle track engine builder and they use them to get around the no gas ported piston rule. They are very expensive and not something I would run in place of a property gas ported piston on a power adder engine. If you are on gasoline stick with lateral gas ports which are located radially above the top ring or if you are on methanol the conventional vertical gas ports work great since methanol doesn't create carbon that can stop them up like a gas engine will. The ported rings are really thin at the port locations and not something I would want to expose to super high cylinder pressure not to mention what detonation could do to them. Just my $0.02

Play it safe with lateral gas ports in pistons
I don't trust gas in any amount on standard radial gas ports.

I've got them in my coyote currently. The pistons were not gas ported so I went with them as an option...have no idea any gains or losses since I never ran it without the gas ported rings.
So far I've had no issues however I run relatively low boost (<20psi currently) compared to some of you guys.

Thanks for the info Turbo11, I was concerned about the possibility of detonation breaking them at the thin port areas, although my boost level is only 25psi and I'm using good fuel.. I thought it may have been a quicker way to get the job done seeing as how I'm buying new rings anyway. Could you define very expensive?, can't find a price for them anywhere. Looks like it's back to the mill.

I don't think breaking them is a big concern since they are generally available in stainless steel or M2 tool steel. The ones my buddy runs in the circle engines are usually CRN coated SS and very thin, like 2mm or less. He has told me they are around $1200 a set but I'm not 100% sure if that is engine builder pricing or customer price. Either way the price sucks. The most I have paid for a set of rings are the Total Seal AP Gapless, CRN coated M2 tool steel top ring, Napier 2nd and 3mm oil rings in my billet SB that were $750 dealer cost. Technology and/or bulletproof shit is expensive as hell but I guess you get what you pay for..........

Mine were like $600 including a specific ring compressor. 1.2mm top gas ported

Hmm, it would make more sense to gas port the pistons, I don't see $1200 (or even $600) in a set of rings, certainly not in my 1400hp combo. Thanks both for the info.

No problem. Just for curiosity's sake I will find out what kind of unobtanium the circle track rings are made of. He's not the kind of person that would double the price on somebody just to make a quick buck.
