There is no reason for you to run a 41 nozzel IMO, dynos always like more fuel, drop that to a 40 and I'd be shocked if it didnt run faster again.
I am same CI with more power and have no where near that much fuel, mine would be a slug with that much fuel.
Did I read right your water temp was 220 degrees after a run ?
Your gaining ground but from the dyno #'s I seen I thought it'd be a 7.70s player.
I don't have any 40 nozzles. I have 39's and ran them on the dyno with a 82 main pill. It made about the same HP and torque as the 41 nozzles with the 88 main pill.
I will change to that configuration next Sunday.
I just talked to Moroso, and they too are puzzled that the header evac system seems to work better than the vacuum pump. He also didn't think that the catch can being in the airflow was contributing to the oil spray. I just thought that maybe with the high speed air rushing through the filter, there would be a venturi effect.
When the engine was on the dyno, the vacuum pump only spit out a couple of tablespoons of oil in 23 hits. That sounds more like what you get from yours.
I did get much better RPM with the header evac system than I did with the vacuum pump hooked up.
