[QUOTE="Erich, post: 8939579, member: 65819"] Yeah, I have a blow thru setup. I also thought the power was low for that much boost. Here are a few more details-anything you can spot? Only 20 degrees of total timing at the top. The first run at 23 degrees of timing was at 540 at about 6000 rpm and going up pretty sharply. Then with the amount of boost it was going to be making (on 93 octane) he stopped the run and backed off on the timing. I don't have a good feel for if that is a normal amount of timing etc. Would I make more power with less boost and more timing? The cams are 03 cobra which are supposed to be the same as the mach 1/marauder and maybe even mark VIII. So less aggressive there but 03 cobras make a ton of power with a pulley swap. I am assuming my cams were timed in correctly. Running thru 03 cobra exhaust manifolds-I doubt this explains it but they are no long tubes. Could my cats be messed up? No codes anyway. The heads had some work done on them and flow better than original. Not sure what else. It is a pretty much stockish built 4V with alot of boost. Erich [/QUOTE]
