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.
