In my update post I noticed Clark related the dual intake readings to a 3 cyl engine and doubled the HP value of 5.11V to show what a 6 cyl would produce. He did not double the volts and multiply by 100. I am not sure where I got the attached VQ table document, as I have had it for more than 20 years. But it has shown to be a close approximation when looking at the dual intake consult data as a 3 cyl and doubling the HP on my car. My first dyno tune was done by Clark when I still had a single intake, at that time the dyno showed 403 WHP @ 4.80V. My last dyno tune @ SZ with dual intake & Selin set to average, was 460 WHP @ 3.89 (refer to table and double HP). Both these are within the attached table HP approximation range, especially when you consider the higher in the range the more close the HP number is.
