Vararam C5 Ram Air Kit
Vararam C5 Ram Air Kit
The B2 system for the C-5 Corvette has evolved several times over the years for added performance and ease of filter maintenance. In the latest evolution,of this record setting system we have made advancements for both Quality and ease of installation. Our customers have asked for it and we have delivered. Here is just some of what we have changed.
The Upper Air box
We have retooled the upper air box completely, The filter flange area has been increased to enclose the new cotton gauze filter properly, The seating radius had been altered to lower the box quarter inch and allow for more uniform compression across the filter surface area. We have added a perimeter gasket around the filter, encapsulating the filter creating an air tight seal every time, so NO leakage! The box material has been changed to more impact absorbent material.
Here we spent a great deal of time adding many helpful hints and shortcuts to make the installation fast and easy. We have added ALL NEW pictures, that are large and clear, greatly improving the ease of installation over older kits.

No cutting or drilling
Comes with VR Super Street filter
OEM Look and you get to keep your fog lights!!!
In the case of all VR ram air units, true power output will never be able to be measured on a dyne as they are designed on a race track (to be moving). All are tested at varying speeds with multiple multipliers in them in order to function at the desired speed and pressure levels, not noticeable on a static dyno (if you like strong dyno numbers instead of unbelievable on track performance simply disconnect the ram tubes or contact one of our tech staff to find out how to adjust the VR for your power needs). What it comes down to is during the design process you must determine if you are building a ram air system or a system to pull numbers on a dyno. The reason being, each property PULLING or PUSHING, has its own internal aerodynamic package. The VR-B2 has a multiplier system in it (this will hurt pulling air flow static, due to there shape, this can be negated by using an extra half inch step in front of the filter but then it will delay the ram effect as well). This is similar to a blower drive or turbo multiplier. It is applied to airflow at each given speed. Example: say you had an after market cold air box that at 75 Mph was 90% efficient. The VR is over 100% efficient at that same speed. Now at 100 Mph the cold air is still at 90% (more than likely is has slipped to 88% efficiency, typical of this type of setup). The VR is at well over 100% efficiency and climbing! This is a gain that you will never see on a dyno.
All ram air boxes are about the same aren't they?
We love answering this because in the after market it seems that very few ever care to really talk about or emphasize to you the customer that if you want a fast car you need power and torque developed under the curve. Everyone is so concerned about peak power on a dyno that they forget two things: 1. The car needs power under the curve to accelerate. 2. The intake system must be able to recover, build and maintain air pressure as quickly as possible. This means making the intake as efficient as possible NOT at PEAK but during shift recovery under the curve requiring proper air box design and internal systems to increase velocity pressures to help offset any head loss incurred in the system. As independently dyno tested by Cartek and C5 Super Tuner shootout winner Danny Pop, the VR-B2 made anywhere from 2-4 rear wheel Hp more than this competitor at peak but at 5000 Rpm they both saw 5-10 Hp more while sitting on a dyno on stock and modified cars. The VR-1B was designed to perform under the curve. The system will typically gain the same or more torque than Hp depending on the filter used and the year of the car.
