1. By tilting the throttlebody downward to a specific angle of attack (Our secret), this allows the lower pathway to open up to its near 100% full volume. WE spent many hours fine tuning this angle in order to get the proper throttle response and velocity.
2. We also designed a balance plenum inside the
bore. This allows the manifold vacuum to pull across the total neck
area in a more uniform fashion. This action reduces unwanted
pressure drop, and increases air flow volume.
3. We re-aligned the bore to help balance vacuum which increases
flow velocity. (The stock bore is egg shaped)
4. In the rear of the Power Wedge we have integrated a variable radius air horn to boost the airs velocity just before it enters the body of the intake manifold plenum. Pushing flow and power even higher.
5. We kept the Power Wedge to a minimal thickness allowing for proper idle pulley clearance on all OEM applications. This will vary from engine to engine - LS-3 vs LS-2.
6. Construction- CNC machined from solid Zytel plastic, the same material most OEM intake manifolds are made from. This ensures that there is little to no added heat soak and that you will have a part that will last the lifetime of the engine.
7. Installation time is about 5-10min and uses your existing OEM bolts.
How does this benefit the
engine at such a low/RPM lift value?
Because we are not increasing the volume of the intake runner or
cylinder head, the flow increase will substantially increase the RAM
TUNING inside the intake manifold runners. The increase is occurring
at the most important area, the beginning /lower area of the
pressure wave. A pressure wave acts like a wave coming to shore,
building boost pressure behind the intake valve. If the base energy
of the wave is increased, it strengthens the wave exponentially
towards your Torque peak. This will show up in the form of TORQUE
increases from low to mid-range RPM’s. The Torque increases will
carry up the power curve leading to an increase in overall HP all
the way to redline.
Data Logging has also shown a consistent +.10PSI increase in the
manifold pressure at 5200-5800RPM on an LS-3.
A Stock LS-3 in a Corvette or Camaro will normally hit a max of
14.40 PSI@ 5200RPM and pull back to 14.20-14.10@ 5600-5800RPM or so.
This is the max power peak RPM range on a stock LS-3. (RPM over run
between shifts will always show a false numbers on data logs)
How much Torque can this add and where will I notice the
gains? Based on the flow increases we normally see,
this would yield approximately +18-20ftlbs at 2500-4000RPM from a
stock LS-3. Mid-Range numbers are usually +12-14 ft. lbs. @
4500-4800RPM on a stock LS-3. Our Dyno testing of Corvettes,
Camaro’s etc. verifies these figures. The horsepower generated at
higher RPM will depend on the amount of torque gained down low and
in the Torque peak.
Custom tuned vehicles:
This product offers substantial gains; these gains will result in
more airflow, which means more MAF scaling. Some vehicles that have
been custom tuned may need to be retuned so the MAF does not over
scale. Using the LS-3 spacer MAF scaling will rise substantially at
lower/Mid-Range RPM levels, + 175-250HZ, peak HZ is usually
+90-120HZ.
(VR Equipped Camaros only, A6 & M6 models)
If the vehicle is custom tuned or has a Tuner on it, it will need to
be re-tuned to realize the gains from the Power Wedge. If the
Vehicle is not retuned the MAF will over scale causing the ECU to
delay/pull timing advance and it will go rich.
WHY only the VR? The spacer will move the
VR closer to the throttle body, increasing MAF scaling and it will
run leaner, by 1%. The flow increase is greater with the VR than for
any other intake system because it accelerates airflow even sitting
still by design. (The MAF numbers will rise well over
275-300HZ@45-4800RPM and 125-200HZ@ 5800RPM) basically its maxing
out the MAF sooner. Simply upgrading to a Tune model tail section
will allow the MAF to go up to 700hp.
