[QUOTE="Extended Power, post: 1521990, member: 898"] I usually have 100psi drive pressure, and about 85psi boost. 30-32psi from the 91mm, and about 85 overall. Every time I take my intake manifold off, I see that I have soot inside it. Which to me seems like the drive pressure is pushing back into the intake when the intake, and exhaust valves are open at the sam time. (A very short amount of time, but both open none the less.) I thought Chris' reasoning for his cam timing made perfect sense...only have the intake valves open when the piston is drawing air in, and only have the exhaust valves open when the piston is pushing the combustion gases out...never open at the same time. My friend has a Straub cam in his duramax, and did not degree it, and it is slower to spool then with a stock cam. Now he has to pull it apart and degree it. This is why I'm asking for help from Chris, and here, so it's degreed correctly on install. I should mention that I also have a wastegate controlled by a AMS 1000 controller, but instead if the dump tying back into the primary's hot charge pipe, it just dumps to atmosphere. This is another item I would like to address this winter. [/QUOTE]
