[QUOTE="madman1234509, post: 1176049, member: 3910"] You get back pressure issues from the amount of exhaust you're motor is trying to push through the turbine. You get flow restriction and heat from your hp not being able to flow enough intake air. Really what it'll come down to is you pushing the high pressure out of it's compressor map, creating extra heat from flow restriction, and grenading it. There's more to it then the high pressure just being able to "flow" . You've got to remember it's trying to compress already compressed air. Do you have any idea what kind of back pressure people are seeing with a 75 or 76mm drop in and a stock hp turbo? Or is all of this just speculation? I'm just curious. I haven't heard of anyone having back pressure issues with a 76 drop in on stock fuel. Our vgt housing is huge when the veins are open all the way. I bet I see more back pressure on a daily basis with my set up then any drop in and stock fuel [/QUOTE]
