The New Generation<br />
A MODERN DAY, HIGH-POWERED HEMI<br />
Recently we heard that the<br />
9-second barrier was broken<br />
in just four short years.<br />
Ring Package<br />
The ring package was moved<br />
down .125-inch to accommodate<br />
the supercharger. Since these are<br />
specifically designed blower<br />
pistons, the ring lands will be less<br />
susceptible to lifting under high<br />
loads (below).<br />
The piston pin on these<br />
pistons is way up there, seemingly<br />
just a fraction of an inch<br />
from the bottom of the piston.<br />
But surprisingly, the pin boss<br />
only intrudes with the oil ring.<br />
Totally Square Engine<br />
It’s exciting to write about such a new engine<br />
combination, especially when it has parts in it that have<br />
not been released to the aftermarket yet. Rickards and<br />
<strong>Wiseco</strong>’s Brian Nutter came up with an inverted dome<br />
(not a reversed dish) design that provides a much more<br />
efficient flame front and provides more quench area than<br />
previous dished designs. Rickards explained, “The<br />
problems with the first generations of late-model <strong>Hemi</strong><br />
pistons was that they came with a reverse dish, not<br />
inverted dome. With the reverse dish you lose a lot of<br />
quench area of the cylinder head. With this new <strong>Wiseco</strong><br />
set, we’ve developed a piston that allows the flame front<br />
in the cylinder to be much more controllable.” Rickards<br />
continued, “The wrist pins have also been relocated closhardcore<br />
parts starting to be released, despite this downed economy. This year’s<br />
amount of new <strong>Hemi</strong> parts has allowed engine builders to push the limits and find<br />
weaknesses, and it seems everyday we’re learning about new components that<br />
will make the late-model <strong>Hemi</strong> run quicker and faster. With a steady stream of<br />
new, hardcore engine parts being released this year, these engines may start to be<br />
taken more seriously when it comes to performance and racing. It happened with<br />
Ford’s Modular engine, and now it’s become a major threat in some heads-up drag<br />
racing classes. The new <strong>Hemi</strong> aftermarket is a little far off to support purpose-built<br />
race motors, but it’s getting there.<br />
Last year we covered a Vortech supercharger install and dyno tune on fellow<br />
office park tenant Dimitri Cretikos’ blown 6.1L <strong>Hemi</strong> Charger. This year, Cretikos<br />
wanted to step up the power with a K1 Stroker kit, as well as some trick internals<br />
that have yet to be released, so Fastest Street Car was there to check it out. When<br />
it comes to late-model <strong>Hemi</strong> building skills and design, Josh Rickards of Vaca<br />
Performance is the man to talk to, and you could even say the 5.7L and 6.1L <strong>Hemi</strong>s<br />
are Rickard’s specialty. Rickard’s claims this new 426 engine will propel a full<br />
interior Charger into the 10-second range.<br />

411<br />
4The K1 <strong>Tech</strong>nologies<br />
crank features a 4.080-inch<br />
stroke while the block is<br />
also bored to 4.080, a<br />
totally square<br />
engine. This provides the<br />
Mopar-essential 426 cubicinch<br />
number.<br />
4The first generation of<br />
late model <strong>Hemi</strong> stroker<br />
kits required the builder to<br />
remove the piston<br />
squirters. With <strong>Wiseco</strong>’s<br />
new 6.1L blower pistons,<br />
you can still retain them.<br />
