The VR-6 uses a ram air effect from the upper plenum chamber to accelerate air past the secondary bottom venturi. This decreases the time to peak velocity by 10%. This gives the system the same velocity at 10 mph that a ram air system generates at 80 mph, which helps to increase low end acceleration for your truck or SUV.
The VR-6 features…….
Cobra box uses multiple venturi system to accelerate air flow in a true cold air system
Designed to produce up 30 HP and up 30+ FTLBS of torque** throughout the RPM range
Flows up to 1278 CFM
Increases throttle response
Increases gas mileage 1-3 MPG
No cutting or drilling
Comes Standard with VR RED FILTERS
** (as tested on GEN III 6.0 liter)
We guarantee that you will see at least a 1/2-to a full second drop off of your 0-60 MPH times over factory stock no matter which GM truck or SUV you have or VR will buy the system back, but we are going even further, We guarantee that you will gain at least a full second ?OVER ANY OTHER? after market air induction system or we will buy the unit back. We at VaraRam chose a very conservative performance improvement figure that we knew ANY truck or SUV (whether V-6 or V-8) would see based on our test data from our competitors products in real world conditions rather than a dyno. You will also see a fuel mileage improvement from the system; usually this is about 2-3mpg over factory stock. The heavier and slower the vehicle the stronger the gains EX: when towing a 5,000lb trailer with the same 2004 6.0 test mule we were seeing the 0-60 mph times drop by 3-3.5 seconds (21.3-21.5 to 17.8-18.3 seconds) fuel mileage rose to 10 mpg from 5-6mpg when towing.
Here are just some of our test numbers from several of our test vehicles. All runs were made as direct before and after runs with NO computer re-learn time. All 0-60 mph runs were made using a Vericom VC 2000 backed up by a PI Research on board telemetry system to monitor MAP, air fuel ratio and overall vehicle performance.
