Solution j_martell Posted February 8, 2015 Solution Share Posted February 8, 2015 the granite i used to run has a powerleash, it worked not bad concidering it was on an 11 litre motor...its a compression brake, sorta like a Jake Brake.....opens the exhaust valve at the top of the compression stroke....basically using the vehicles momentum to run the engine as an air compressor to waste kinetic energy..... 1 Quote Lack of planning on your part does not constitute an emergency on my part....

wheeler73 Posted February 8, 2015 Share Posted February 8, 2015 The MP engines also use the engine brake combined with the turbo closing off for engine braking.

Green Dash Posted February 8, 2015 Share Posted February 8, 2015 The driver can choose what speed the brake will come on at. I'm not sure if that's common these days but I've only seen on/off or 2-3 stage types. It's a pretty cool feature.
