Drag Racing Billet Pistons
Potentially Lightest-Ever Drag Racing Billet Pistons for Big-Block Power-Adder Engines Now Available
Diamond has introduced what it believes to be the lightest-ever billet aluminum pistons
with button retainers for big-block power-adder drag race engines.
from 2618 material and designed for use in Pro Mod, Alcohol Dragster, Alcohol
Funny Car, and Outlaw 10.5 race engines, these latest innovations reduce
reciprocating mass by up to and beyond 40 grams per piston. Changes in the
layout of the piston’s struts and webs as well as the introduction of sizable apertures
to the pin bosses account for impressive savings of 20 to 30 grams. Further changes
that include shortening the piston pins yield another 10 to 15 grams.
this efficient arrangement of struts and webs has had a profound effect on the
piston’s strength-to-weight ratio. Significantly stronger than a conventional forging, these
new pistons possess the inherent strength to combat poor rod-stroke geometry.In
addition to their lightness and strength they are center balanced.
Available with dished, flat top or domed profiles, these pistons are
supplied with top or side gas ports (or both) to maintain thorough ring seal.
They are also equipped with button retainers for rapid piston changes. End play
is limited to 0.020in (0.010in on each button).
New big-block billet aluminum pistons with button pin retainers reveal
reciprocating mass achieved by new structural designs and short pins
best yet strength-to-weight ratio attained by new, deep web-style
TP1 piston pins (Trend’s hardest and toughest) provided
or flat-tops or domes with crown thicknesses of 0.200in to 0.300in
or side gas ports (or both) applied
packs comprising 0.043in, 0.043in, 3mm or 1/16,1/16, 3/16in
- Offered in Diamond’s double-coat (hard
anodized with moly skirt) or uncoated
Diamond completes the kit with Trend’s toughest and hardest
piston pins, the new TP1, and Total Seal’s ring packs 0.043˝, 0.043˝, 3mm or 1/16˝,
1/16˝, 3/16˝. Lastly, these pistons are offered in Diamond’s double-coat (hard
anodized with moly skirt) or uncoated.
