Seating in rings

Just wondering how most people seat in a new set of rings on drag engines I have always after braking the cam in let the temp get up to about 240 with the rad cap off and shut it down and walk away until it is completely cooled down then just run the crap out of it never yet have aset not seat.Like I said just wonder how other do theirs

get it up to temp, put it on the transbrake a few times, take it to the track, start it and do a burnout .....

Fire it up and do a LONNNNNNNNG burnout

Like has been said....just get the engine to normal operating temp. & put it on the transbrake a couple of times. If the rings are not hooked up by the time you put into high gear, on the 1st pass, chances are that they aint gonna hook up.

Break it in like you stole it!

Well no transbrake bont gota one so i just drive it like I stole it from popo catch me if you can

With my gas motors, I fire it up and let it run at about 2500 for 15-20 minutes. I also set the timing while its at that rpm.

Is there a different proceedure if you are running alcohol?

Being honest ... that all really depends upon the bore finish quality and the rings used.
Do you know the Rpk, Rp and Rv ...?
The rougher the bore = the less temperamental; as long as it is straight and round.

Whatever you do, (in any case), don't allow any excess fuel to wash the bore before the rings get fully seated.

the rings seam to have seated in great I did seat the on gas before I put the alky to it

I usually start it dry and let her idle till you get heat in the heads then shut it down and let cool....pour in water and check for leaks and Run it like you stole it...

How can you tell if they didnt seat?

when it blows the dipstick out during a pass at the dragstrip...........

You have a dipstick? Fancy.

The best way to tell is to look at your header outlet and look for a oily residue. If you wipe your finger and it feels oily,they aren't seated completely. If they have a dry look ,chances are they are seated.

Rings have to seal in BOTH directions; going up & down.

An engine may not burn any oil at all but, still have a ton of blow-by.
