Neither did I, and that's not what I wrote. The response I wrote was to someone else writing a "Fast" properly set up car can do 130-135 through there, not a stock Evo. I asked the question because I was concerned the thing would top out around 140, which I could see the car hitting at the apex.
if i remeber right, one of those japan videos they tested the top speed for the Evo MR vs GSR vs RS . And the RS did the Highest top speed. All factory. The reason was the light weight and less down force. I think that was one of those best motoring videos.

Well what he means is in a stock evo there no way in hell you will hold 140 around that corner out of the apex. For one stock evos boost taper too much and after 130 or so they start to slack off. Yes they can do 150+ it just takes awhile not something a back strait will give enough room for. With 320-330whp now thats a different story...160mph dont take very long at all

Speaking of boost... I've driven a total of two Evo's. An MR I test Drove, and my SE. The MR I clearly felt the boost taper off. I knew ZERO about Evo's when I drove it, and I made a mental note to shift the thing at about 6k or so rpm. Anyway, I bought my Evo from a dealer two hours away, so the first time I drove it, the car had been delivered, and I already signed for it. Anyway, the boost "taper" had left my mind, and not until like the third or fourth time in the car did I notice that this one seemed to carry the boost damn near to redline, if not the entire way. Bone stock, brand-new Evo with 200 miles on it. I have no explanation for it, but you can clearly feel when the boost starts to taper and on the SE, it just doesn't.
Now if I could get my SE to stick like that MR did (they delivered it with a severe pull to the right, and after they "fixed" it, the thing wanders on the freeway), I'd have the best of both worlds. Thank goodness I have a good chassis guy 20 minutes away.

-Also-
At the apex, bikes will be on the side of their tires, which increase the rpms substantially. If you deform a car's tire in this area the same thing will happen. While this won't be the reason for the high speed, it'll be a reason for the motor to spin higher in the area (the apex), before the tension is released in the chute. Some guys will actually use this to their advantage by using the rev-limiter as "traction control", to keep the tire from spinning excessively, and drive going forward.
At the risk of coming off as an egomaniac (as barf360 suggests), I have thousands of laps at Willow, and have a very intimate knowledge of it. I can't tell you where T3 is at Miller, but I can tell you the pavement imperfections at the entrance of T9 at Willow you use to breathe your motor and turn in .
I'm not the expert some of my friends are, who often tell me you don't know Willow until you've crashed in every turn, more than once, but I know enough to allow me to turn faster lap times than someone with more skill than me.

^^^If you are talking about Turns 8 and 9 at Big Willow, the car accelerates way past the apex of T8 until the braking point at the entry to 9 (which is before the apex of 9). Then the car accelerates past the apex of 9 all the way to the braking for Turn 1. It's impossible for the car to be at its highest speed at the apex, and would be counter-productive. It's HPDE 101 for newbies -- slow in fast out.
Exactly, I should have mentioned that- from the factory the top speed is limited to 155 mph, but will the top speed limiter removed (reflash), 165 at 7000rpm is what I have experienced with the 06 IX MR 6-speed tranny... felt amazingly stable at that speed, no different than what 130mph feels like, although it was a smooth recently paved surface.

Your "HPDE 101" doesn't work for T8.
