Before we get too excited, anyone see my post earlier, about the throttle cable issue on the same dyno? That would certainly have an effect on tims dyno number if in fact, thats what was happening, but not in the boat. Throttle controls when using a servo, can fuk up. I like when some shops mount a camera above the throttle plates during a dyno pull, where you can see creep back.

A more common cause for both the low measured air flow and vacuum would be that the carburetor was not mechanically at WOT during the pull. Sometimes it is hard to get good carburetor travel with the available leverage and linkage. Older dyno's with the water piston used to creep all the time and loose the WOT during a test session, even the newer ones with servo or cable linkages can creep or loose the WOT capability.

I was pro 4500 dominator on this build from the get go, so don't get me wrong. I'd still like to see a dominator on it.

Tim, mount a vacuum gauge on it in the boat. See what you have. Then try the flame arrestors off. See what you have. Then crack the hatch open, and see what you have.

This would be alot easier if you had daytona sensors boxes using a map sensor, and data logging this stuff.

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

Yup, I am the idiot checking this and watching the fuel in the bowls (glass sights) while on dyno during full swing.

Wanna laugh ? I'd always cover my nuts with my hand(s). Like that would protect me. Hah !
