What is meant by….Trick ring face
Maybe someone else will be able to help me answer my question.
Have a great night.
FWIW
I understood your question perfectly. and
I understood your follow-up quotes, perfectly. and
I too, have no idea what a "trick ring
FACE is". Unless that applies directly to the following line in the article which reads;
If you have 5/64" rings, spacers and Dykes, metric or other trick rings are the thing.
EDIT
IMO; the lack of decent punctuation in the above statement could have been better, and that would have made this conversation almost moot. Below, I rearranged it to make proper sense
If your pistons have 5/64" rings; THEN
spacers, Dykes, metric, or other trick rings, are the thing.
; which mentions "spacers", "Dykes", and "metrics", all lumped together as trick rings, for pistons with 5/64ths grooves ; which are, or used to be, somewhat unusual configurations for an automotive engine. Nowadays you just order your custom Pistons for whatever configuration, but, according to the article, pistons have to be, "stock configuration".
The Dykes, are common in some hi-performance motorcycles.
Metrics are becoming more common.
Spacers have been around for a long time.
So then, I suppose, those "trick rings", are the same as; "specialty rings" for a car; but not so trick in the racing world.......of which I know very little.
As it is put forth in your quoted article; my "interpretation" of "trick ring packs" and so called "faces", is that these are special designs to reduce friction between the faces of the rings and the cylinder walls, in very hi performance engines.
There are also other, "trick rings".
and; Even tho I don't need to know about "trick ring packs", I still like to know that stuff.
