The  C6  "snake charmer" is the result of a serious 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 to many customers and racing teams that it’s 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 drivability 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 dynoing (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 10mph- 180mph. The snake charmer is over 108%-123% efficient!!
How much power will you get? 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 when you've reached 60mph  - 19-20 H.P. - by 90-100mph and the way we rate our kits is through a ¼ mile Your total power through a ¼ 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 ¼ mile. This power shows up in the testing performance of the unit where we see gains of the fallowing,.
3.5 -4 tenths off the ¼ mile
+3.5-4mph+ added to the ¼ 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.
