Top speed at max rpm

Simple. Few supercars reach 200 mph, and have A LOT more HP than what the OP claimed, and are A LOT more aerodynamic. Simple physics. If everything else checks out (stock size wheels/tires, proper pressure, level road, calm wnds, tune didn't add a 'correction' factor to the speedo, etc), OP has a lot more power than he claimed. The M3 is NOT a 200-mph car without major modifications, period. Good day.

It's also been argued that it's not a low 4 second to high 3 second car...but it is. Actual accounts should speak louder than modeling...but for some reason they don't. A person posts up a video showing him driving over 200 mph with the Vbox in plain sight and the reaction is always, "An M3 can't go that fast." Um, you're watching the video proof....nuff said!

I don't know about the M3 in the video, but there's no way my stock M3 (or my friends) can go near 200mph. The f430 has more hp, more aerodynamic, it can't even break 320kmh, how can the M3 outperform the f430?

Thought stock m3 was good for 180 to 185. After that it takes an exponential increase in power and reduction of drag for each mph up the ladder.

crazy.

What crap. A lot of folks are in serious need of some adult supervision.

Gear ratio - F1 car has 800 hp - with weight around 700 kg - and with specification for "slow" track will hit limiter at 320 km/h ...

203 is what I saw on my speedo before braking at the Florida Mile last year, well thru the 1.5 mile marker

Sorry guys elp is absolutely correct here. It is simple physics and simple physics speaks way louder than a video. Who knows what car was shown in the video. 414 hp with the drag coeficient and frontal area makes the M3 simply NOT a 200 mph car maybe not even 190 mph.

As far as the car making a 3.9-4.1 second 0-60 that is well within the realms of possibility for a car at this power and weight. Thus that is not a good counter point.

Also, this particular topic, top speed, speedo correction, etc have all been beaten to death with many threads here on the forum. IIRC the speedo correction is close to 4%, I don't think it is as high as 5% on stock wheels (then again I have never tested it well above 100 mph personally.

Ugh....and so it goes.

Separately, I see you live in SD. You should come out to one of the meets.

All I know is that my gauge cluster shoots weird colors when I hit Redline in 6th.

A stock M3 is not a 200 mph car. Today, some dude on this forum posted a 207 mph run in a 570 hp M3. Thus, a 415 hp stock vehicle is unable to hit 200 mph. It's impossible.

Also, WTF is everyone redlining their cars in top gear? This is stupid as f*ck and ridiculous. No need to do this on a public road. If you are on a track/strip, all good with me, but still dumb IMO.

Again. The higher octane fuel, the higher power and torque. I'm not surprised that someone's doesn't hit 290 km/h (180mph) by stock M3 if refuelin' 91-octane urine.

So let's go back:
