Great! Interesting to note that the spreadsheet for predicting top speed 
from HP that one of the Steves and I worked up a few years ago used the 
formula (Rear Wheel Horsepower) = (Flywheel Horsepower * 0.88) - 10.

Assuming a  238HP 560, we get (238 * 0.88) - 10 = 199.44, so we were 
pretty darned close. In fact, one of the references I used suggested we 
should subtract 15 instead of 10, which would have put us smack on the 
money! Thanks.
