Pontiac G8 Ram Air Intake

• 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 1/2 second! (As tested 5.2 stock vs 4.7 & 4.65 best with
   VR system NO TUNING!) With a tune, we saw 4.4 sec but no grip to go faster.
• Reduces 1/4 mile ET by 3 tenths and adds +3mph Minimum Guaranteed, or we 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.

We 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 is 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 we exceed 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. We 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 we set our target numbers as 800hp/500CID and 7000RPM and built the kit from that figure. We also used "Internet Forum Members" as our testers, so they could be involved in the design process from day one.

The 1st prototype performances proved to be better than anticipated.

This was a more production type unit, only missing the finale tweaks (and maybe +4 hp more) than the production unit would have. The result well…How about 102Kilopascals@only 48mph! (101 is an atmosphere) as DATA logged by EFI Live. It also delivered stronger 0-60mph numbers 4.6-4.7 seconds with a severe traction problems using the AUTO trans car. (Original prototype mule was a 4.85 best in better weather, than what we were currently testing)

Here again its not about peak "BOOST" or peak flow numbers its about how it makes the car accelerate "UNDER and THROUGH-OUT"the power curve.

All modern EFI cars use ram tuned intake manifolds and as such when the plenum of an intake manifold is placed under constant pressure rather than relying on the engines vacuum, the return signal that begins the internal ram tuning effect inside the intake runner never has an opportunity to weaken as it makes its wave cycles. This strengthens your Torque and power under the curve substantially, usually far beyond the peak power number generated from the product.

An example would be that on an LS-3 as measured inside a running engines intake runner we measured almost +1.5 PSI. With our intake in place and our intake pressure system functioning we measured + 2.25-2.31 PSI @ 1 atmosphere or 14.696PSI that’s a gain of .75-.81PSI INSIDE the runner by simply KEEPING the manifold pressurized! On a stock LS-3 that’s about +25hp. Remember this is INSIDE the intake manifold RUNNER, NOT the plenum. The plenum has enough volume to deliver the HP/CUI ratio at the set RPM limit from GM however it drops pressure during its cycles as all engines do but when any VR system is in use we always deliver the efficiency needed to produce max power and Torque, by keeping the manifold plenum at 1 atmosphere or we put it in full boost, that is pressure above 1 atmosphere.

We are also the only company that offers a performance guarantee with EVERY product we sell. It will do what we say it will or we will take it back and pay shipping both ways!

For the G8 We contacted forum members to test using multiple streetcars in both stock and modified trim as well as running for max mileage. The results speak for themselves.

Once again, VR used the Internet and real G8 enthusiasts to build what you asked for, a product that performs beyond expectation and delivers what is promised. The entire VR staff would like to thank the G8 community for allowing us the opportunity to work together to produce a product that will continue to build on the VR tradition of winning races and setting records for yrs to come.
