At a glance:
• Produces a real-world 35hp+
• A direct bolt on
• No chopping or cutting on the car
• Unreal throttle response
• Flows 1400-2000CFM+! (Depending on the filter used)
• Reduces 0-60mph by a full ½ second! (As tested 5.2 stock vs 4.7 & 4.65 best with
VR system NO TUNING!) With a tune, Vararam saw 4.4 sec but no grip to go faster.
• Reduces ¼ mile ET by 3 tenths and adds +3mph Minimum Guaranteed, or Vararam will
take the unit back and pay shipping both ways!
• (NO TUNING) w/ tuning you will go even quicker.
(Technical information and why it looks the way it does)
The G8 unit was a true exercise in packaging.
Vararam had to package as much flow potential as possible in 5 inches of length! This includes a removable front scoop, for the interchangeability of different scoop designs for street and racing combinations. (sold separately) Advanced staircase lower floor- this creates negative pressure to turn the air while minimizing turbulence, exceeding the flow of a smooth transition. (If you look closely inside the kit, you can see the mill marks where the unit was milled by hand in order to achieve the precise angles required). Large overlapping flanges are used – this allows the use of thicker, higher flow filters for future power or racing use while maintaining a proper seal for pressurization.
The filter - An exclusive unit again for VR, made to VR specs for pleat depth and spacing to maximize flow for every square inch of material. The standard 3/4-inch unit (As was tested and flowed VS competition) 1400CFM @28 inch of water 1 inch SD street filter 1600CFM @28 inches of water, competition units 1850-2000CFM+. During ram effect they exceeded the ratings listed above by 15%. The main air box features a two-step air horn for low and high-speed aero packages for increased throttle response and low RPM windup for quicker stoplight-to-stoplight acceleration. Enlarged neck ID capable of accepting stock-100mm+ air meters for heavily modified cars. Military specification materials are used throughout from the custom extruded flat black plastic capable of 275 deg F to the quick release low-pressure latches. High lower arch allowing the use of larger, taller radiators if the need ever arises.
(A MUST READ)
Take the time to look at just a small amount of this systems development. Vararam had over 12 pages of data and reduced it to what you see.
This system was designed from day one as a true ram air system. The design is set around the new GM ZETA platform that will also become the new Camaro.
(Some history and technical information)
From its inception Vararam set the target numbers as 800hp/500CID and 7000RPM and built the kit from that figure. They also used “Internet Forum Members” as their testers, so they could be involved in the design process from day one.
The 1st prototype performances proved to be better than anticipated.
Vararam built five more complete development units that incorporated different aerodynamic design elements. They also used general purpose ABS as their heat test- this material is only good to 150 deg F. There were no issues. Production models use Military spec high temp materials good to over 270 deg F.
Its 1st performance exceeded the performance of "ALL" of the current kits that were available by reducing 2-3tenths off the 0-60mph time and over 2 mph and 2 tenths more in the ¼ mile, than the rest of the aftermarket could produce!
This “Thing”(Vararam's Prototype) was well…to Vararam anyway “A RIG” far from what they could do. Vararam also tested against several “over the radiator” Australian units and one US unit. The VR prototype out performed them all by strong margins ranging from 1-2 tenths more on 0-60mph runs and 1-2mph through the 1/4mile. Some of there units were worse than factory.
(Vararam was now set to start full development program)
They had already beaten the best the rest could offer; now Vararam set out to beat themselves. They began by testing multiple scoop designs biased on the airflow they measured from the radiator cavity and were quite surprised to find that if certain angles were not correct pressure was not maintained and the scoop velocity would drop by 70%! This was why so many forum members kept asking what the “BLACK TOWEL” was for? Well to hide the scoop design and its angles of attack, because just like an airplanes wing some angles worked well and others looked pretty but simply did not deliver the velocity needed for actual ram air effect.
The RAM EFFECT and the G8 – the nose of the G8 is a funny thing, because although you would think that just putting scoops directly behind the front grills would be ideal this proved to deliver “LESS” flow than the location they used. Vararam tested several versions before taking airflow readings “INSIDE” the radiator cavity and found that by converting the pressure generated from the lower and upper grill assembly they could create more velocity than from a direct front mount scoop.
Flow bench data- at VR, they “KNOW EXACTLY” what works and what does not! They measured flow thought every popular kit not through the kit itself, because that is meaningless garbage! All that matters to you is flow through the intake system that is delivered directly into the cylinder head! "IF IT DOESN’T SHOW UP HERE, IT DOESN’T SHOW ANYWHERE!” unless of coarse someone is playing games on a DYNO!
FLOWBENCHES DON’T LIE, DYNO’s and PEOPLE DO!
