ended up with 5400 = 67.7 , 8000 = 73.3 . it only gained 4lbs the whole pull. the oil is 10w40 . The first couple pulls the oil psi was dropping and we added one quart. But the psi was in the 80's, honestly i dont remeber how much HP it gained from just that. I know its not a big deal here, but i really dont want to talk about HP numbers. [/quote]
Didn't need to know your HP, just curious if the lower pressure showed any meaningful gains. Doug
