Here is a compressor map for the 66mm turbo which will be no where in the range to get you 85ibs/min. What year is your truck? The Turbonetics turbos use a/r ratio for meassuring the turbine housings not CM. The 66mm turbo will get you in the 600-650hp range and if you are looking for 800ish hp the 72mm turbo will get you there.
