Johnny,
Please excuse my thread-jacking, but I just bought 55 gallons of C-16 for TMH's/Jailer's/now my Turbo Busa. KKK 27 unit. Air to air intercooler. The boost is adjustable from 15-30 lbs. I would assume with straight C-16, 30 lbs would be no problem. Crower rods and Carpenter Springs. 18/40 gearing. Heavy clutch springs. Basically, a modified MC XPRESS system. You might know this bike, it is purple and black and Dennis used it as his personal ride for a time. McIntosh 5 1/2 inch reinforced arm and raked 3 degrees and lowered 2 inches.
