carbon apex seals question
the one i'm going to ask if anyone still used them? i have a race motor that came with carbon seals and they didn't last long at all. total of 10 races total (6 practice days and 4 races). ethier im doing something wrong or i should get different apex seals. should i do super seals? btw is a 6 port n/a street port engine setup for 3/8 oval track car we turn 9500-9800 for 2 session of 10 laps and a main feature of 20 laps. any opinions about or tips? thanks

the competition book wants you to pull the engine apart every 1,000km's or something with the carbon seals.
you do need to make sure the clearances are right also.
you could try to add more premix, although they just aren't going to last that long.
if its a 2mm seal engine, the stock seals are perfectly fine up to about 8500-9000, and they will last a lot longer.

A mate still uses them and has for a couple of decades in his circuit PPs.
You won't get long life out of them if you use the rpm, he will go more than 10k and does them a couple of times a year, sometimes they break in use, which just results in low comp on a couple of faces, don't think about dropping them in assembly!
They're very kind to housings, which will last almost indefinitely. Wouldn't consider aftermarket steel or stock seals myself. If you wanted long life, probably ceramics - but prepare for a complete engine replacement if they did let go.
