You're right. I was playing around with it and left that value in there for the Lightning on accident (and it's probably pretty close to that I would think, maybe even a bit larger). The other values posted earlier were actually for the 300ZX - but obviously frontal area was too large... Using your value of 20 ft^2, I get a top speed of 168.24 mph, assuming 225 whp (300bhp minus 25% drivetrain loss). The 100bhp extra from a JWT ECU plus intake/exhaust would raise the top speed to only ~186 mph.
Of course I'll have to verify these numbers with some real-world testing on residential roads at night in a rainstorm with my lights off.
