The VR-SC1, After 1 full year of
R&D the all new C-6 Snake charmer ram air induction kit is finally
ready for the street. The snake charmer is a heavy development of the
original C-5 B2 unit. We used information gathered from 12 special B2
Race units that we constructed for racing only, these units featured
many different internal aerodynamic packages and filter combinations, to
maximize peak CFM and time to peak manifold pressure. We have
emphasized too many customers and racing teams that its not just peak
pressure but the time to peak manifold pressure that we look at, this
occurs at shift recovery, down in the meat of the power curve. This
helps for shooting off of corners, general driveability and overall peak
performance, this shows up in the form of Torque& Lots of it. Like
all VR units the snake charmer was not designed for the dyno (pulling
air) it was designed for ramming as such the aero package and shape of
the unit are designed around this. The philosophy is simple; design for
the most efficient aero package possible at all speeds ranging from 10
mph- 180 mph. The snake charmer is over 108%-123% efficient depending on
the filter used.
The Filter:
The filter for this unit was custom designed in house and
produced by a subcontractor for Donaldson. It is a pleated unit that is
washable and reusable, but that is where all similarities end, the
filter features deeper pleats and more pleats per inch than other
filters and the peaks and valleys have been opened to further increase
flow capacity per square inch. The end result is a very compact high
flow filter that will out flow K&Ns of similar dimension by over 30%
while actually giving better air filtration, you simply have more
filter area that is effective area not dead space. We used the latest in
fluid dynamic software to check the flow path of the snake charmer; we
say check because the snake charmer was originally designed by hand by
company president Patrick Ledford. The flow is so well balanced into the
mass airflow meter that at full speed 180 mph+ the airflow is within 1
mph across the entire circumference of the entrance leading into the air
meter, the factory tube is not that good!
Rainwater will not affect
this unit, nor will down pours, you will have to submerse the nose of
the car.
Construction:
The unit is formed using two construction processes, the
upper is roto molded to ensure a seamless internal aero package leading
into the air meter. The second, the lower scoop is vacuum formed, this
has been done to allow us to alter the scoop and its aero-packages to
suit specific applications, giving us more flexibility and performance
in street or racing use. This ensures maximum performance at all times.
Performance Guarantee!!
So now the how much power
will you get question- standing on a dyno without using any special
programming you should expect 10-15hp from any cold air kit,but once
moving the VR will put all the lost MAP pressure back into the plenum
yielding another 17hp by 60mph 19-20by 90-100mph and the way we rate our
kits is through a mile Your total power through a mile is about
another 22hp plus the dyno hp of 10-15hp,so, on the low side, 32 Rear
wheel hp, high side 37 Rear wheel hp. That's 39- 42hp at the fly wheel
through a mile. This power shows up in the testing performance of the
unit where we see gains of the following:
3.5 -4 tenths off the
mile
+3.5-4mph+ added to the mile trap speeds
+7-10MPH to the cars top speed
That is serious performance considering that is right out of
the box, we will continue development for further performance, but we
have maximized the factory programming so more may be possible with
custom tuning and we are working with tuners and racing teams now on
such programs, so look for these in the future with a VR program or
upgrading to a VR programmer if you already own one such a programmer.
