I believe the civs are able to reach about 145 with the correct engine.

Here's the equation, I'm too lazy to do the math myself. Find ht edrag coefficient and find the horsepower, and see if it's possible.
--------------------------------
Ft (Tractive Force) = D + R

Where D is Aerodynamic resistance, and R is Rolling resistance

D = ρAvCd

Where:

ρ = density of air = 1.2kg/m

A = frontal area = 0.9 x width x height
A = 0.9 x 1.695 x 1.495 = 2.28m

v = velocity squared
200mph = 322km/h = 89m/s

Cd = coefficient of drag = 0.36 (Civic hatchback)

D = 0.5 x 1.2 x 2.28 x 7921 x 0.36
D = 3901 N

R = KrG

Where:

Kr = Rolling resistance coefficient.
For tarmac Kr = 0.025

G = download = mg = 1200 x 9.81
This is a "stripped out" version so mg = 1199 x 9.81

R = 0.025 x 1199 x 9.81
R = 294 N

Therfore tractive force Ft = 3901 + 294
Ft = 4195 N

Power = Force (Ft) x Velocity

420hp = 313Kw = 313,000w

Velocity = Power / Force
V (m/s) = P (w) / Ft (N)
V = 313,000 / 4195
V = 75m/s

75m/s = 270km/h
= 168mph

For 200mph:
V = 89m/s

Power = Ft x V

P = 4195 x 89
P = 373,000
P = 373Kw
= 500hp

Cd = coefficient of drag = 0.38 (Civic Coupe)

A = 2.11m

D = 0.5 x 1.2 x 2.11 x 7921 x 0.38
D = 3810 N

R = 294 N

Therfore tractive force Ft = 3810 + 294
Ft = 4104 N

Power = Force (Ft) x Velocity

420hp = 313Kw = 313,000w

Velocity = Power / Force
V (m/s) = P (w) / Ft (N)
V = 313,000 / 4104
V = 76m/s

76m/s = 274km/h
= 170mph
--------------

I copied and pasted, so try to sift through all the other stats from the civic's numbers. (this was originally used to prove that a civic can't hit 200 mph).

Posted earlier in the thread but:

I still have my top speed at 145 in a Sentra SE-R Spec V....During a test drive. In my car hit the limiter at 137, and in my old CRX I hit 115.

You could say that. After an engine swap, air intake, headers, catback, suspension, stage two clutch, short shifter, rims and rubber, I'd say Gina's somewhat modified.

Geeh does that mean that tractive effort doesn't require a torque figure, only power? My goodness
