Performance Tables for 74 P337 vs Riley Super SkyRocket

[DrZGard]

I have taken the book figures to make a couple of Excel spreadsheets for performance tables comparing a 1974 T337G to Riley's Super SkyRocket conversion with the TSIO520's. The book figures only show MPH and LBs of fuel burned and total range exhausting fuel (which is a misleading figure). These tables add Knots, gallons per hour and range with 45 minute and 1 hour reserves. The 74 SkyMaster carried 123 gallons/738 lbs while the Super SkyRocket carries 148 usable/888 lbs.

I turned the excel files into pdf files since they didn't want to upload.
