not sure what Yokes you have but comparing 205/55 S.drive to CN36 215/60,
gearing cost is ~ 17.3lb-ft and inertial cost increases the net cost by ~2.3lb-ft because though the tires weigh about the same the weight is further from the axis of rotation
Additionally you will want to change the fronts to a taller tire, either 185//70 or 195/65 which may potentially add to the torque cost
currently 82mph is ~4k, w/ 215/60 it would be ~87mph
as John says changing 5 to .72 also changes 4k to 87mph

thanks bill, always appreciate the feedback.
car has 21/29 mm Tbars, and was running 215/60-15 when i bought it. wasn't quite as low as it is now and had a fair bit of negative camber and i had no rubbing issues. this is how it looked:
fwiw, when i finished building this car, i put 205/50-15 RE-71's on. it was just too low for the car's intended use by the time i got the ride height where i liked it. it was also geared too low, that's how i ended up with the S drives...
