BD-Power Variable Vane Exhaust Brake
With the change in technology as the newer truck models rolled out of the plant, we at BD have changed as well to apply our over 20-years of braking technology to match. With the newer Chevy Duramax engines, the change was already there, we just had to utilize it for your engine retarding needs.
The same Garrett variable vane turbo design is used in the 2004.5-up Duramax engine to reduce turbo lag and increase power can also help slow you down. BD utilizes the variable technology built into the turbo by closing off the vanes while retarding creating up to 35psi of back pressure. What does this give you? Ample retarding horsepower to help maintain your speeds on descents and curves giving you better control of your truck and load.
How do you use it? While in Tow/Haul mode, switch BD’s Variable Vane Brake on and every time you let off the throttle it will close the variable vanes in the turbo which develops exhaust back pressure in the engines combustion chamber, creating resistance against the piston from reaching top dead center.
Is it easy to install? YES! Most of the connection is done via an existing diagnostic port on the engine making for an easy and clean installation.
Is it hard on your truck? Not at all… We have designed our brake to not make harsh downshifts into lower gears that can cause tire “chirp” and drive train strain. The Variable Vane Exhaust Brake is also firmware updateable via the internet using your computer's USB connection and is the perfect fit for your Duramax towing needs.
The VVB rotary switch offers three different modes included automatic
moderate and aggressive downshifting programs for the Allison
transmission to give better weight control. Exhaust braking also works
in Allison manual shift selections. The VVB integrates with the cruise
control to automatically accelerate and decelerate to maintain vehicle
Easily and simply installs by plugging into existing factory ports and
by mounting the rotary switch on your dash. All of these features in one
package which with some competitors would require two separate ones at
nearly twice the price and twice as long to install. Now that is value
added engine retarding at it’s engineered finest.
Note: Compatibility cannot be guaranteed with all aftermarket products that have a permanent connection to the OBDII port inside the cab. At this time the Edge Products CS/CTS & older Attitude Monitors along with H&S Mini Maxx are not compatible.
