Go to
www.bankspower.com and check out "yes, buy thier own definition the "exhaust brake" that they manufacture! It is an exhaust brake, has been and always will be!
Calm down already.
I am well informed on the various ways to retard a vehicles forward motion.
This thread is about the
Banks Speed Brake kit. This kit has no mechanical parts, only a control module that goes inline of the trucks engine harness'. There may or may not be a display unit, my truck used a Palm PDA to control the brake.
The Banks Speed Brake works my manipulating the VGT, (variable geometry turbo).
The turbo vanes are controlled by a solenoid and by closing them down you have the same effect as a downstream “exhaust brake” without the mechanical pitfalls of those units.
BTW – both GM (couple of years now) and Ford (MY 2011) do the exact same with the turbo.
The GM works pretty good, the Ford is pretty lame.
