i know our truck dont have these, but is there a conversion kit we could run.
Plus they are on opposite sides of the turbo. Wastegate diverts exhaust gasses to control drive to the compressor. Blowoff is on the compressor side to blow off excess boost to the engine when load is suddenly decreased.OK, stupid question here.
What is the difference betwen a blow-off valve and a wastegate?
None of them have one - it's an aftermarket add-on. Stock LB7s have a pressure-actuated wastegate and rarely bark. The stock LLYs have the VNT turbo and you can hear most of them bark on some of the pulling video clips here on the Place. Just as they stop the pull and chop the throttle. (Makes a strange "whoop-whoop-whoop" sound). Like CAP said, only a problem in certain special situations - made worse if you've got a big turbo on there and pushing big boost.do the lb7's have a BOV? if not, why not?
at what point is a BOV needed on a duramax?
Well, you're pulling a sled with every ounce of power your truck can develop until it just can't pull any more. At that point stress has been building and has reached a maximum deadlocked against the weight of the sled. If it's stopped moving, you want to relieve that stress as quickly as possible before something in the engine and driveline snaps! No time to feather it down.why do they chop the throttle like they do?
