Friend of mine swore he hit 160 in his RSX Type-S. Though I wasn't there to see it. Wanted to add that bit in.
I think there are a lot of factors at play beyond simple HP. Wind, altitude, drag, weight, tires etc.
A reflash may remove the limiter and thus, a V6 TSX might hit somewhere near 167 mph (it does have 280 hp and is fairly aerodynamic) but other than that, there's no way that a TSX is doing that kind of speed.

Well drag limited and limited are two different things. Go pop on youtube 133 is not the limit of a stock car. Since this was a few years ago I don't have any proof of it. The stock car will pull about 150 in the right conditions.
Here's some dude in a 4cyl auto pulling 142. He claims it was windy. A manual might have done better. https://www.youtube.com/watch?v=GunNo53GN94
Might point wasn't to start a pissing match over top speeds. It was only to stay 300hp isn't required to go 167mph. It's a combination of a lot of factors, drag being the major factor.

I don't think you've proved your point at all. Nothing shows 167 mph in your videos - you're 25 mph short in the best of them and that's INDICATED speed, not actual speed. It would be typical to be off by about 3% at speeds that high, which would reduce that "142" to "138" with no idea of whether he has a tail or head wind.
In point of fact, cars that I pointed out as being capable of near-167 mph speeds have 275+ hp, which would support my claim of 300 hp being required far more than your claim that 200-ish hp will do that kind of speed. In simple point of fact, 200 hp will not give you 167 mph unless you're in a tiny car with very low drag and small frontal area. I challenge you to find me one factory car with 200 hp that will PROVABLY do 167 mph.
You aren't trying to start a fight but when you claim something quite different, it opens it up for requests for proof of your claim. So far, you've provided none except a fuzzy recollection and a video of a car that's 25 mph short of what we're talking about.

It depends on the size of the vehicle and the front end profile of the car to name a few limits. There's a video on youtube of an Ap1 hitting 270kph. It's not putting out 275hp.
And the video I posted was because you're internet debating. C&D says 133 so you cannot hit more then that. It's a load of crap. Go drive a car and report back, don't quote me some 'drag limited' stuff.
Of course I didn't record it, even if I had would I have it all these years later to prove my point online? No, not likely. Take it or leave it. It's about as worthy as your comment of 300hp = 167mph.

That video doesn't load.

Here's 270kph with about 240hp, blows out of the water your need for 275 for 167.

A couple things:
1. Not stock, so it's putting out more power (exhaust and intake) so probably making 250+ hp
2. Bigger tires - 1.3% increase in speed
Add it up and you've got a car that's reading 270 kph but actually traveling 266 kph, assuming the speedo is dead on (it's not). And that's in a car that's geared VERY short (not typical, certainly not with a TSX) so you'll need very good gearing to hit those speeds with that little power.
Again, you're nowhere near 200 hp to get that speed and you're not actually hitting a true 167 mph.
My point stands - 200 hp won't get you to 167 mph and it'll take closer to 300 hp in a car like the Civic. We already KNOW it has more than 275 hp (Honda has said so) so the question is, how much more? I'm guessing 300 hp.

1. The speedometer in a car could differ significantly at larger speeds, if it would have shown a GPS reading the accuracy is better.
2. We do not know if he is driving downhill or not.
Most magazines have tested the s2k to be close to the factory claim of ~240km/h when using real measuring equipment.
Just to give you some figures to think about: (Source: http://ecomodder.com/wiki/index.php/...t_of_Drag_List)
S2000 CdA value is stated as 6.47
E36 BMW CdA is stated as 6.24
A M3 E36 (eurospec 321hp) tops out around 275km/h measured with GPS, since the drivetrain configuration is similar (front engine, rear wheel drive) we can expect similar drive-train losses. So to get a s2000 up to these type of speeds, you would most likely need a bit more than 320hp.
Regarding the civic, it will have less drive-train losses since it does not have the rear axle differential, so maybe it is possible with 275km/h with around 300hp if the CdA value is low enough.

I had my stock s2000 pinned for a while and hit around 225 km/h on a flat highway. There was a strong cross wind and the rear felt floaty and very nervous. It was very slowly climbing but it would take minutes to make it up to 240
I will never try that again without some rear downforce.

I think you're getting in over your head. You're saying correct things, but you're not connecting the dots. Yes, drag is the predominate factor. Guess what overcomes drag? Horsepower. Ergo, there is a correlation between drag and, hp, and top speed.

Also, I didn't mean that to sound so mean. Sorry.
