According to the widebands, the fuel mixture was pretty consistent on the dyno. The airflow turbines didn't seem to be showing anything weird. Both engines were showing the same story.
I'd like to say it was the camshaft. But, there certainly can be something else going on. Unfortunately, there just wasn't alot of time there on the dyno, to really play with things. Tim pretty much had 1 day to dyno 2 engines, and head back to ohio. The dyno numbers, seemed to pretty much show, what he was, or wasn't seeing, in the boats performance.

very much considering M4 pro chargers, mild boost for now... 3-5lbs until I rid the TRS, try to be easy on it unless water is calm for WOT beatings, if I have to chop throttles forget it.. haha

I know, but one of your what ifs is if your exhaust is holding you back. Dyno headers might have quantified that. Did you guys happen to log vacuum on the dyno? That would tell you if your carbs are holding you back.

We gotta stop "figuring" at some point. Ryans a buddy, but my first dyno pull, my engines made 650hp. I vomitted in my mouth a little bit. I insisted something was wrong. He was like "eh, my dyno's conservative, and its a 468" . I asked him to open the throttle all the way on the dyno console. Oops, throttle was only opening about 60%. Next pull, 761hp .
