Introducing the new VR Power Wedge for LS engines (LS2, LS3, and LS7) and Hemi 4G. Increases airflow by as much as 10% on some LS2 applications. From Idle to max RPM, increases power and Torque across the entire curve! In some applications EX, stock LS-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 throttle-body 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.

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 at checkout 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!

Wedge is 102.5MM starting bore with taper to a 93.44MM final bore

If you would like to increase your engines performance by using some of the most efficient air induction systems on earth, LMPerformance is pleased to offer a line of Vararam air intakes and other products.

LMPerformance research has shown that ram air intake works by reducing the intake air velocity by increasing the cross sectional area of the intake ducting. When gas velocity goes down the dynamic pressure is reduced while the static pressure is increased. The increased static pressure in the plenum chamber has a positive effect on engine power, both because of the pressure itself and the increased air density this higher pressure gives.

Your vehicle can become a high-performance vehicle by installing one of our Vararam air induction systems which produce more Power and Torque, offering you more real world performance than any of the other intake system out there. Vararam claims to use the latest in aerodynamic technology and real world testing to produce intake components and parts.

The testing of the VARARAM Air Grabber and other VARARAM air intakes is not done in a hurry just to get the job done but rather is a time consuming and demanding process and usually takes up to a full year to be finalized because the evaluation process is only successful when it has evaluated an application’s restrictions and then reduced them successfully to zero, and after that VARARAM force feeds the engine or tunes the system to a particular application. By taking such care during this juncture in the total process VARARAM is able to increase the overall performance of a vehicle to its greatest potential and give you, the customer, a product that you will be happy with. Products like the VARARAM TRI-Power for your GM Truck and SUV, and something that has been lacking in the marketplace for some time, but after careful testing what began as an idea has finally come to fruition – a direct bolt on real ram air system. Forget about the old way of doing things with chopping, drilling and water ingestion and just bolt this baby on for a horsepower gain of anywhere from twenty-five to fifty, and no air meter issues with this product because it has a custom Tri-Power air filter by GREEN that uses air sensor safe oils; and best of all, it is available for your Avalanche, Escalade, Denali, Tahoe, GMC 1500 and 2500 trucks and Chevy 1500 and 2500 trucks. Own something a little smaller say a Corvette C-5, well LMPERFORMANCE and VARARAM thought of you too with the sui generis B2 system that has been evolving since it was first developed and performs as the record setting system it is, and the third time around is definitely a charmer for this performance addition with a retooled upper air box, an increased filter flange area that totally encapsulates the filter, improved box material and other improvements. And improvement is the name of the game when it comes to VARARAM as is evidenced by the Cold Air Super Street System VR for your Camaro that has been redesigned from the original version in order to remove the volume and manual adjustability and then came a tweaking of the cold start operation that was problematic in the Camaro until it was perfect.
