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 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.

BUT,What about that 220*Temp @ the Stripe,...........?>?
With ALL the Fuel you Throwing @ the Motor,where did that Temp come From?Are you Certain,theres NOT Serious Pressure in the Cooling System,......?//?

Only way he needs this much fuel is, there is a vacuum leak, barrel valve is screwed up and not getting full fuel, or the pump is weak.

I had the Enderle 0-1/2 pump flow tested. It was 5.5 GPM. And the car did pick up between run #2 and run #3 when I changed the pill and put a little more fuel to the engine.
Could my oil spray be because, on decelleration at the stripe, the oil in the top of the head rushes forward to the vacuum pump pick up? Has anyone else encounter this?
I am gonna tear the vac pump down, clean it and check it out. Then hook the vacuum pump inlet hose into the #8 AN breather outlets on the valve covers I use for the header evac system. I will change to the 39 nozzles and an 80 pill and see what happens with the temp and the ET.

The decelleration should be stopped with the moroso fitting in the valve cover as long as its not just some 12an fitting weleded to the valve cover, but I am sure you went through this and have the right fitting. You know the dirt track guys have a guard on the front of there breather canisters to stop dirt from coming it, possibly you could get a guard like this to stop air. Or stefs breathers suck air from the bottom and is incased.
Did you get a chance to drain the oil sense you've been home and be sure there is the right amount of qts of oil there ?

I haven't had a chance to change the oil yet. I will do that on Friday.

It was a mistake I made because my mind was on the vacuum issue. Just a bit inattentive!
