VHP new “ACCELERATED LIFT” rocker arm
geometry has
opened the door to a new area of valve train development and cam lobe design
that is producing impressive results. The “ACCELERATED LIFT” geometry is not
magic; it is simply a new design of the rocker arm body that locates the pushrod
seat low in the body with respect to the center of rotation about the shaft.
Because the pushrod seat area travels in an arc as the lifter/pushrod moves
upward during the lift event, the pushrod seat moves slightly away from the
center of rotation around the shaft. This movement of the seat through its
operating arc causes the effective rocker arm ratio to decrease. The end effect
is this: a 1.6 ratio “ACCELERATED LIFT” rocker arm actually starts opening the
valve at a ratio of 1.7. As the valve opens, the rocker ratio decreases to the
1.6 advertised ratio (this occurs at about .250” - .300” valve lift) and then
maintains the 1.6 ratio through the rest of the lift cycle until it starts back
on the seat. It goes back on the seat at a 1.7 ratio. This
new geometry provides increased airflow earlier in the lift cycle and maintains
it longer into the closing event. More flow equals more power! There are
additional benefits. The “ACCELERATED LIFT” design applied to computer managed
engines means that short seat-to-seat timing can be maintained to provide high
vacuum at idle and low speed, but duration at .100”, .200” etc. is equal to
camshafts having .050 durations 8 to 10 degrees bigger. This means great power
increases and ease of tuning the engine management system. “ACCELERATED LIFT”
geometry is the future for pushrod engines and VHP
has it for you today!
VHP has also
designed new camshaft lobes to maximize the advantage of these rockers.
The new “ACCELERATED LIFT” lobes are being used in all of our new racing
profiles, as well as our new LS1 family of cams for GM cars and trucks.
Performance enthusiasts have known for over 25 years that the best lobe design
to maximize “area under the lift curve” is the “inverted flank roller lobe:”
However, the “inverted flank design” creates several manufacturing headaches
which cause the price of these designs to be quite high.
VHP'S new “ACCELERATED LIFT” Rocker body design and new
complementary “ACCELERATED LIFT” cam lobe designs have produced a valve lift
profile that exceeds the power potential of the “inverted flank” designs. These
new profiles are available on all of the latest LS1 cams, including the “Truck
Power” cams and many of the new racing cams. Most of our future pushrod
camshaft designs will incorporate the “ACCELERATED LIFT” technology.
