Excellent teaser question PRH. Not much going on right now, so I will wager a guess.
No idea what horsepower would be, and don't know how much it makes a difference for ET compared to horsepower when a chassis really works well, but I am going to guess head flow was in the 375-385 cfm range. Probably way off, but I would follow up by asking if the calculators get farther away from reality in a well sorted car when the volumetric efficiency goes past 100%, and what engine platform was this with?
