We set our design target to support 800hp/ 500 cu inch and 7000+RPM, all while keeping the system easy to install and making it a ?TRUE cold air system that breathes better when the hood is ?CLOSED vs. Open on a dyno.
We accomplished this goal through intensive on road and track testing which revealed the shortcomings of every other aftermarket system we tested from US and Australian manufacturers.
They ?ALL suffered from heat soak- the Holden /GTO has a sealed engine compartment. This allows very little air in or out, so these cars run HOT naturally, let alone if the motor is built or supercharged! (Creating more heat, remember, horsepower is heat!)
We tested kits that used many configurations, some went over the radiator some to the fender and others sealed to the hood, ALL of them heat soaked the mass airflow meter and air box assembly. This in turn caused the ECU to pull timing out of the motor and this also forces the tuner to detune for the street or track VS the dyno with the hood open and a fan blowing.
Step One
Here we relocated the MAF Meter in-front of the throttle body, this improves response and makes for a more accurate read that any tuner will see on a data logging system ex EFI Live, HP tuners etc...
Step Two
Here we placed the MAF meter ?INSIDE the air box with the filter to shield it from the engine heat.
Step Three
We created a positive seal around the perimeter of intake plenum chamber. We force feed the chamber via the front grill area by taking the natural pressure rise that occurs here and converting it to velocity via the plenum chamber.
By force feeding the kit we build some pressure inside the plenum chamber which we convert to a rise in velocity in the air filter base inlet design. We confirmed its function by measuring outside temp VS actual MAF measured intake temp the result? The actual measured intake temp was consistently lower than ambient by 2-3deg F.
Step Four
Air filter flow- in testing we found many of the Australian front mount filters either did not flow enough air to support the HP or the angles of the air box were incorrect to flow air at the highest possible VE ( volumetric efficiency) . We flow tested ?ALL ?of the aftermarket kits US/ Aussie on our in-house superflow flow bench all the way through the cylinder head. The results were well..., what we expected, by themselves every kit out flowed factory, but just making a big or less restrictive hole truly tells you nothing! Flowing through the head from .100-.600 inches of liftat 28 inches of water (SAE standard) gives you a true picture of what gains are being realized by each port. We calculated this out to HP and found when we had customers dyno test there numbers were within 1-2hp of what we estimated they would gain, Stock or modified.
Step Five
Delivering the flow to the filter- here we have the customer trim the upper most portion of the radiator shroud, this allows for a full 2 inches of clearance across the hood line area when the hood is closed. We measured this at a VE of 90% and came up with 1,725 CFM! (Opening the scoops showed a gain of 300CFM more at 90% VE) 2025CFM if needed!

Vararam Industries is well-known for manufacturing the finest ram air systems for your performance vehicle. Extensive testing and development go into every performance part that Vararam produces. The company delivers on its performance claims by building induction products, like ram air and cold air systems, that improve airflow to increase horsepower and torque figures. Vararam Industries builds products for Dodge Hemi engines, as well as the Chevrolet Silverado, Corvette, Camaro, Pontiac G8, and more! Vararam’s powerful systems feature the latest in aerodynamic technology to eliminate air restrictions and improve your car’s performance. Each individual component and system is built, tuned, and tested for specific applications without taking any shortcuts.
Vararam Industries was created to bring true racing technology to the street by offering more real-world performance than any other intake system on the market. Compared to other systems out there, Vararam’s comes out on top every time. Its intake systems let your car’s engine breathe more freely with as little restriction as possible to deliver performance gains of up to 20 horsepower. Vararam uses a very tedious yet rigorous testing process of evaluating restrictions and reducing them to zero. The team then force-feeds the engine or tunes the system to particular applications to maximize the overall performance of that vehicle. Vararam’s priority is to make torque and power under the curve, rather than just peak power.
If you are looking to give your ride some substantial power gains, then look into an intake system from Vararam Industries. Vivid Racing carries a wide range of easy-to-install Vararam induction products that are made from top-quality materials. Our inventory of Vararam parts includes cold air intakes, short ram intakes, power chambers/ducts, and velocity stacks. If you have any questions regarding the items listed above or about Vararam, please do not hesitate to call our expert sales team at (480) 966-3040.
