Alright Whats the BEST ring to use?

I used Total Seal in the past, Hoever since I pulled the old engine apart and found them in multiple peices I am not so sure about them. But many other factors could have caused the demise of my rings, so I am not blaming them. but otherwise what do you trust, Simply what is the best???

 

Which rings were in pieces? Be more specific....

 

well it was actually the second ring and the oil ring. The ring land on the oil ring managed to snap off above the wrist pin holes. and the oil ring got pushed down in between there .

I am thinking it occured due to some significant overheating that occured . I did file the rings when I first built the engine, but I didn't do it right, All I did was place the old ring in the cylinder bore and then the new one and then filed it till it was the same as the old. I ran it for over a year before going TT, it wasn't till I did this that I experienced overheating, and even then the engine ran strong. but once I decided to pull it apart, thats when I found the pistons were well demolished. I am glad I have learned so much more since I built my first engine.

 

i'd like to try and answer as i built a turbo car years go, but i looked in your profile and i can't find anything to base my answer on. :sad:
but i'll take a guess:
the best rings will have the correct end gap for the application. and be nodular iron :smash:

 

Well my previous setup was a 350 bored 40 over, Forged Flat top pistons, standard no frills C rods, and nodular Crank. I didn't dig into detail when I first went TT and just went according to what the reciepts stated when I bought the car "it said it had "stage 3 rods" and forged crank" neither of those were true. Anyways WP 67cc S/R heads, with torquer intake, 950cfm holley double pumper. as for the turbos Air research T04B's this is how it looked As you can see, it was not the most pretty setup. And well didn't last either. Up to the point of me taking it apart though it did run like a raped ape. but just overheated after about 20 minutes. I then decided to keep with the idea, but get serious about it. No backyard throw together job this time. I will have to get some pics of my new setup, as it is much shinier and better built. It's almost all done, I just need a ECU wether it be F.A.S.T. or Accel, or Haltech. A cutch, piston rings, then send off the rotating assem to be balanced. once that is done, I can finally peice it all together for good, and be done with this.

I guess my only worry is, The Total seal seems like the best setup I have seen around, and my engine lasted for over a year with them installed with out a problem, But once subjected to high heat they just snapped. I cannot confirm how this occured. wether it be I didn't have a perfect end gap or not. All I can say is it worked for a while.

 

smart idea to go with EFI. the old set-up probably had lean cyl's that got too hot, when the ends butt, they snap.
i really dont know anything about total seal rings with TT. i would just run Speed-pro with std. tension oil rings. and a wide end gap due to the experimental nature of the TT's. With forged pistons .030" would be pretty safe.
See the articles i wrote in my sig./profile. Not about T's but you may find something interesting.
How much boost did you run? :cheers:

 

well before I re ran my wastegate lines I pushed 15lbs. When I finally got the wastegates to read correctly I had it controlled to 10lbs. I am thinking of going with the Speedpro moly rings, But at the same time I just want the best available.

 

Speedpro/Sealed Power also makes "HELLFIRE" rings for forced induction/nitrous applications.

quote: Speed-Pro’s “Hellfire” series piston rings are the ultimate ring design for use under extreme racing conditions. The product of extensive research and development, our unique new HF479 material and ni-chrome plasma facings have been proven to deliver unmatched power, durability and sealing. Hellfire rings have been tested and proven in NHRA Pro-Stock, and in NMCA “Fastest Street Car” competition. Over the last year of testing, these rings have become the most talked about “speed secret” among professional race engine builders. The HF479 ring material retains tension despite intense cylinder pressure and heat. It is easy on cylinder walls and pistons and is still able to survive with mega-doses of nitrous oxide. Ni-chrome plasma is the latest innovation in piston ring face coatings. Another Speed-Pro exclusive, this ultra-durable material delivers superior scuff and wear resistance, and outstanding resistance to flaking due to its amazingly strong bond to the base ring material. Speed-Pro competition series piston rings combine metallurgical superiority, race proven design profiles with the machining excellence which made Speed-Pro the undisputed leader in cylinder sealing technology. When compared to steel piston rings, Hellfire rings deliver higher crankcase vacuum, greater high RPM power and improved oil control.

Sound pretty good to me :)
Good Luck! :cheers:

FWIW, check out this site> http://www.nmca-racing.com/forums/index.php Go to General forums, then go to pg 9, look for the "Gapless/Zerogap ring thread. Some good info put out in that thread, hope this helps.

sounds good to me too :thumbs: i didn't know about those.
price? :cheers:
