Humor me, I have lowered my trucks Cd to .32?

"A non-turbo'd, non-Atkinson cycle, ICE engine, at steady speed cruise, might be in the vicinity of 36% thermal efficiency, rather than 26%."

That's good info, the default in the calculator is 22%, I bumped it to 26%.

The same reason I bumped the driveline up, because the calculator under estimated the EPA Highway rating of 23.

Really what I need to do is raise the truck to stock height and start my documentation over, but with two kids under 7 years old, a full time job and a 87 year old mother that I have to take care of, I just don't have time.

But using the information you gave me, I think I can change the varibles and get a more accurate idea of wht my Cd is. My gut feeling is it should be .36-.37
