Made right here in the USA, this new control kit by Smooth Boost removes the old vacuum controlled bypass valve and gives you the ultimate electronically controlled bypass valve to smooth out your boost curve so that it drives just like a Hellcat, powerfully and predictable. That’s not even the best part… With the turn of the Smooth Boost dial you can even set the level of boost you would like from your Whipple supercharger based on your driving plans!!!
For example, lets say you were planning a relaxing Sunday cruise with the wife and kids and you have no need for 12lbs of boost on the trip, just turn the variable boost control dial down to the desired driving conditions and enjoy 4 or 5lbs or even ZERO boost. Then when you are at the track ready to run the 1/4 mile simply turn the dial to MAX and enjoy the full capability of your Whipple supercharger on a SMOOTH boost curve.
