when you run the numbers,my calculator displays out to 13-significant figures,if I do not round,and use the "full display" values,it makes virtually no difference to the end results. The numbers I posted are at a higher resolution than those presented at engineering congresses and I feel that for estimating purposes,they will yield realistic values plus-or-minus say 5%.--------------------------- The whole purpose of books like Hucho's is so folks like us can use the formulas and relationships to interpolate or extrapolate values given some "knowns",to build cars on paper or within the computer,and gauge the merit of particular mods.----------------------- I wish GM had published figures for the Ultralite at a meaningful road speed.Short of that,we're forced to use the tools available to us to glimpse that world.
