Vararam GTO Cold Air System VR-GTO

This will fit 102mm Throttle Bodies

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. (More on this below)

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.

THE VR remedy- At VR we only design our products for the REAL WORLD not a static test, because U dont win races standing still on a Dyno!

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.

(This design does create some ram effect but only at speed above 60mph, unlike our other proprietary ram air systems which build positive pressure in the intake manifold at speeds as low as 37MPH!)

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 lift@ 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.

We flow tested with stock heads and some modified heads with flow from 248, 252 stock -378CFM on heavily modified heads - LS-2 heads as well as LS-3 & LS-7 heads.

NO other aftermarket system supplied could even feed the STOCK heads with the proper amount of airflow they needed from .300 inches-600inches of lift@ 28inches, only the VR accomplished this and did so by a strong margin.

The VR was flowed on a set of SPECIAL heads with a prototype intake manifold (more on this in spring! no comment will be made by our staff, so dont ask) what is important is that we were able to feed the airflow required in a complete engine duty cycle on an engine that would see 700-850hp @ 7500rpm.

Actual airfilter flow is between 1350 and 1800CFM @ SAE standard on anybodies flow bench even on a bad day! ( street filter vs race filter spec)

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!

If this cut is not made it cuts flow by a staggering 50%! Which is why we say flow hood open vs. closed are separate items altogether.

WE have tested; tested and tested as is the VaraRam way and we are very pleased to finally bring you this exiting new kit.

The filter is an oiled Green High Performance filter Green filter oil is MAF friendly and will not throw codes!!

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.
