: I know there is a problem with stock type
: pistons because the first ring is a ways
: down the piston side. Why not have another
: grove cut up higher.

: The only problem with the low ring pack is
: emissions, unburned hydrocarbons hide
: between the piston head and first ring.
:
: Truth is that the low ring pack is good from a
: wear standpoint, tends to be more stable and
: the rings see much less heat for two
: reasons: 1) More piston head material
: between the ring and the fire.
: 2) The ring rides on cooler water jacketed
: cylinder wall. (remember, the SL6 has a
: block deck that is .375 thick at the
: *thinnest* points)
:
: As for adding another ring, it's just more
: parts, hassel, cost, ring friction, etc. for
: little if any benifit in performance. Now if
: you were talking about a engine running a
: stationary generator or pump, running at a
: set rpm, constantly, day & night, year
: after year, an extra ring would help give
: that type of engine some added life-span.
:
: As for the racers, most are now using thinner
: metric ring packs to help reduce running
: friction.
