How Do You Make a 4.6 Go 200mph?

Actually, the theoretical top speed of a bone stock 4.6L without drag and without the coefficient of friction is about 205 MPH. So the question isn't "What planet?" but in between which planets.

Personally, I'd love to have a drag strip set up on Europa lol

And for the 2011 Mustang GT gear ratios:

Using their forumla, under perfect conditions with no tire flex on brand new factory 235/50 18 tires:
(.00595 * (7000 * 13.63)) / (.69 * 3.31) = 248.561452 MPH
Is that correct? (hopefully someone here can clarify for me, as im kind of curious myself)
Edit: Woops. I ran the numbers for the 2011. I guess I am off topic

I hope Skip Barber went to Skip Barber school. You didnt take into effect tire size, or current gear ratios.

My tires are rated for 190-205mph and are considered to be made for "Exotix high performance" vehicles, so I think I'm good on making a speed run sometime in the next year or 2. Think I'll be able to hit 180 in 7000ft (a runway) with stopping distance?

Next summer I should be doing cams and a Brenspeed 302 stroker kit. Then I'll save up and get a whipple.
