Just a simple couple questions. First has anyone used Ceramic seals on a 1/2 bp before? I'm wondering because of the design of the port and the possibility of the seal getting ripped off in it. I know most people use oem seals but has anyone used ceramic? And do you think it would be a good or bad thing using ceramics on a 1/2 bp.

I don't recommend them, Steiner. I think they're a waste of money in my opinion.

Really. Why do you think that? Is it just to much stress on the seals, or do you think that they have an increased risk of breaking or getting caught in the port?

I can recommend a couple of people you can talk to and if you want to go ceramic seals I can hook them up with the seals for you. You will get an excellent price on these seals.

Well I know Brian has much experience that's why I'm anxious to hear his responses. But of course I'm always open to other people's information and experiences. If I were to purchase ceramic seals they would be Ianetti 3 peice 3mm, if I could get my hands on them.

Would it be safe to say that on a 1/2 BP street engine, since one probably would not be reving the engine higher than a steel seal can operate properly at, then using ceramics would be overkill?

 

Ceramics are never overkill. What constitutes over kill, a seal that won't wear out? One that offers some more peace of mind? One that reduces wear? Is almost 2 ounces lighter per set? Why do the N/A guy's run them? It's not only because of high rpm, if I am not mistaken don't the Formula Mazda cars have rev limiters at 6800 rpm? They now use ceramic seals. There are a number of reasons that they were allowed and one of them being the seal to groove wear they were seeing in as little as one race session. The wear was enough to cause power loss. When the goal is to have equal engines for more than a few race sessions, only ceramic seals fit the bill.

Just my thoughts

Well I plan on getting my engine clearenced and treated and all that great stuff, so that at autocrosses I can get into that higher range. Granted this is a very slim amount of time that the engine will be seeing it but I don't want to take the risk. I still want to hear what Brian has to say.

bump, interested in more opinions

 

If i had the money to get ceramics i would (and likly will someday) They can handle higher exhaust temps (leaner mixture more power) and they arnt going to wear out on you for a long long time, there also lighter then stock seals to support higher redlines.

Still wondering about this idea. I'd still like to hear back from Brian as well to see why he thinks they're not worth the money. Has anyone used them on a bp?
