shieeet.... finding frontal area isn't easy, only place I found someone listing it was here, and I have no idea if it's accurate:
http://www.carfolio.com/specifications/
seems kinda close though, assuming the calcuator is talking about wheel HP? (seems like they'd make that clear?!) For my E30, I used:
0.33Cd (I saw a lot of .32 and .34, so I went in the middle)
20ft^2 frontal area (converted from 1.86m^2)
2491lbs (with me in it)
116MPH
78HP (104x.75 for drivetrain loss, seems about right)
That's probably not far off?
I've never topped it out. :oops:
if it had a cam and exhaust and was well tuned, it might make the near 100whp it would need just to go 10MPH faster. :lol:
