[QUOTE="OldschoolPSD, post: 976229, member: 9427"] A real jake brake opens the exhaust valve on the power stroke and keeps everything closed on the compression stroke. So basically, you are cramming all that air and however much boost into the cylinder (which takes a considerable amount of power) on the compression stroke and then letting it all out before the combustion can push the piston down on the power stroke. The effect is that it takes considerable force from the driveline to keep the motor spinning (retarding horsepower or RHP) A 3406 Cat can make over 700RHP in stock form. If a 6.7 PSD made even half of that, you'd need quite a lot of weight on the rear tires to keep them from dragging. [/QUOTE]
