Guest iskone Posted April 29, 2004 Share Posted April 29, 2004 I've bee nplaning on using them in my 383 but I've read they are not meant for the street. What say you? Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 30, 2004 Share Posted April 30, 2004 IM useing them NOW in my 383, personally I don,t think they are worth the extra cost, while they work fine they don,t appear to be giving me and big advantage over good quality standard rings other than slightly better leakdown percentage readings but they seem to allow more oil to burn, nothing bad understand, maybe a pint every 3000 miles, but quality standard rings have done better,yes they are worth a few extra hp, but not worth the extra expence in my opinion UNLESS your racing and need every last hp Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted April 30, 2004 Share Posted April 30, 2004 Grumpyvette: How about if one was to use them in a forced induction engine? Would you still not? Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 30, 2004 Share Posted April 30, 2004 all Im saying is that I personally don,t think they are worth the extra expence for the results, they work fine but I have not found them in my opinion to be worth the extra cost, you will need to make your own decision,but getting a few3-5 extra ho for about $100 more is not really what Id call a great return on invested dollars, a cam or intake upgrade for that $100 would tend to give better results Quote Link to comment Share on other sites More sharing options...
ecp48 Posted April 30, 2004 Share Posted April 30, 2004 Hey guys, While not a chevy or Z, I used them on the top and middle rings of my Formula V, as did/do?? a lot of V Racers. When you are talking about incremental horsepower increases (a National Formula V produces appx. 62 HP on the dyno), every little bit helps. When you're playing around with 355-360 Cu. Inches, you won't notice the difference as easily. As to whether the price is worth it in a chevy, that's a personal call, particularly when most of your increases come in large numbers, not a fraction of a Horsepower. I can say that they were the difference between holding a draft on a National (pro built engine) car on the back straight at Moroso/Palm Beach International Raceway (PBIR) and having them walk away from my home built engine. ecp48 Athens, GA Quote Link to comment Share on other sites More sharing options...
Guest 502ZX Posted May 1, 2004 Share Posted May 1, 2004 I agree with Grumpyvette. I have spoken with lots of racers regarding ring decision and most agree it is not worth the $$$ for the special rings and in some high RPM cases they can flutter and unseal. The latest "trend" seems to be a larger than normal (like 30 thou!) second ring gap used with or without a vacuum pump. The idea behind this is to release trapped pressure caught between the first and second rings which can cause sealing problems, particularly in nitrous/boosted applications. My ring recommendations are go with standard-style rings, if you don't mind the work and minimal extra cost go with a file-fit set and lean towards the tighter side of the manufacturers ring gap settings on the top ring for moderate performance applications. This has worked well for me in the past in some nasty engines. My new engine is using the large second gap I suggested earlier and a Moroso vacuum pump, I'll let you know how that works out later this year.
