Description

Introducing the new VR "Power Wedge" "The One That Works"™(All Patents Currently Pending) for LS engines (LS-2, LS-3 and LS-7)
This is not a spacer, it's a power wedge.
(stock LS3, L99)

How many products can actually make that claim and back it up? Only Vararam!
·Increases airflow by as much as 10% on some applications (LS-2) ·From Idle to max RPM, increases power and Torque across the entire curve! ·In some applications EX, stockLS-2, LS-3, we have seen higher maintained MAP pressures, 10% increase in peak manifold pressure! (Ex: stock at 5800RPM MAP pressure is 14.1-14.20 /2010+Camaro) ·Torque gains of 10 ft lbs to as much as 18 ft lbs and 14hp on a stock LS-3 down in the meat of the curve 2500-4500RPM ·Modified engines will gain even more power Supercharged even more! Tech specs: 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.

Flow testing: To verify the power gains.A Superflow 600 flow bench was used for this test. Flow tested was conducted using a VRX-93 on a stock LS-3 OEM intake manifold and cylinder head.

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.

The Power wedge was born from the VRX Intake manifold program. Our research showed that most of the OEM manifolds had the intake manifold neck pointed upward at about 8 degrees. This is done in order to clear the water pumps and to soften throttle tip in response. In this position , at wide open throttle the blade extends into the manifold neck and plenum up to 1 full inch downward angle position. This blocks a portion of the lower section of the flow path.In short This means that when you are at WIDE open throttle you are only getting about 88-92% of the flow that is possible from whatever throttle body you are running.

The Power wedge can be used on a stock car or a car making insane HP numbers, stroker motors and supercharged applications. They all work with the "VR Power Wedge!"Simply specify your bore diameter and get ready for an all new driving experience. The Torque Curve will amaze you! It will be from 2,000RPM all the way to red line!

CORE CHARGES
Our exchange program is very simple and allows you to receive chrome plated wheels or powder coated calipers without unnecessary down time to your vehicle. We first send you a set of our high quality chrome plated GM wheels or powder coated calipers to have installed. The best way to purchase is with a credit card. We initially charge you for the Chrome Plating
(wheels) or powder coating (calipers) plus a refundable core charge.
You must return your undamaged cores within ten (10) days, we then issue you a full core credit within ten (10) days of receiving the product. Cores returned late (after the 10-day period) will be charged a $30.00 (per day) late fee. There will be a $100.00 stripping fee on painted caliper cores. To insure the highest quality available we only exchange GM products and they must be for the same style and year. Any damages will be deducted from the core refund. You may contact WCC for return shipping assistance.

WARRANTIES
All items are warranted to be free from defects in materials and workmanship at the time of shipment to you. Your purchase will be backed by the limited warranty extended by the manufacturer of the parts. West Coast Corvettes and the manufacturer will not honor warranty requests due to shipping damage, improper handling or installation, neglect, accidents, or competition use. Warranty claims apply to parts only. All Chrome Exchange wheels come with a 3-Year Written Warranty. Our 1-piece reproduction wheels come with a “Lifetime Limited” structure and a 2 year chrome warranty. All wheels should be checked for trueness or run-out before installation, in case shipping damage has occurred. All wheels should be test fit before installation to assure proper clearance of brake rotor, brake caliper, inner and out fender and brake cooling duct. Complete warranty will accompany wheel shipments. WCC does not directly warrant any high performance part or labor. Performance parts are installed at the customers risk and any warranty claim must be taken up with the manufactures. Performance parts may or may not meet individual state emission laws.
