lunati and crane have all jumped on comps bandwagon
with their "voodoo" and "Z" series cams which mimic
comps "xtreme" series by utilizing more area under the
curve to open the valves sooner.
Great concept but these cams are very hard on a poorly
prepped valvetrain especially with their tight lobe
New technology is allowing cam designers to produce
flat tappet grinds that are to some extent closely resembling
roller tappet grinds.
On the same note, roller tappet cams allow designers to
create profiles that are just not possible with flat tappet cams.
On the other hand Crower has developed a flat tappet grind
which looks to be very promising,
It's the Crower Ultra Performance Level 4 "288HDP"
234/246 degrees duration @ .050",
288/296 advertised duration, .497/.504" lift @ valve,
112 degree lobe separation angle, 2000-6200 rpm powerband.
What's unique about this cam is the duration @ .050" lift
and the very wide LSA "112 degree" which accounts for
the BROAD powerband.
This profile is exactly what "Danger Mouse" is wanting.
