Message: [QUOTE="Wayne, post: 999043, member: 863"] Pressure in the combustion chamber from big cfm on the inlet? Yes. Once it leaves the head, the restriction is limited by turbine wheels and housings primarily. 3 compound turbos add 3 levels of back pressure. The gates should work great in theory, but having the vgt as the high pressure complicates things. A simpler version with all 3 conventional turbos might be easier to get going, but that's obviously not happening here. For the simple concept of understanding the back pressure issue, imagine if all 3 turbos were superchargers instead, with big headers going into 4" dual exhaust. I can't see much back pressure building there. I imagine about 300 HP worth of parasitic draw, and crazy boost numbers if you could get a group of chargers to take the abuse and rpm's necessary to make it happen. I am by no means suggesting it's a good idea to try, only using it as an example of how I see the back pressure issue. [/QUOTE]
