Actually that week should be avoided bc there is A LOT of traffic on the Autostradas during that time. It's kind of the Italian 4th of July... they have their version of the Blue Angels fly all over the country that week. This is the same aerobatic aircraft team(PAN) Frecce Tricolori - that crashed in Ramsteim AFB air show disaster in Germany in 1988. To this day airshows are banned in Germany.

Getting back on Topic...


Driving my stock US spec 135i on the Autobahn... even though the speedo read 155 mph(250 kph) - my GPS showed "only" 245 kph.

BMW's are speed limited to 210 kph unless they have ticked the M-Sport option which includes "Speed Syncopation #840" option. Then the car is limited to 250 kph(on the speedo, real speed GPS of 245 kph!). M cars are limited to 268 kph. IF the owner goes to a M Driving School... they get a "code" where their local dealer can code the car to a higher speed limiter of 280 kph. I think a fully "open" vmax for a e9x M car is close to 300 kph.

Discovered my top speed limiter wasn't 130...
https://www.1addicts.com/forums/show....php?t=1283209


Later on I got a euro tune(380 PS and 520 Nm) and an open V-max... my car would do 285 kph constantly. I know a few times I went slightly faster... but I was too busy driving to dare to look down at my speedo. I think I probably was doing 290 or 295ish kph. I have friend's with tuned 135i's and they say 294 kph is the real V-max for these cars. IDK.

Some "slower" vmax's for your entertainment...

274 kph driving one handed...

Thanks mate, I know, I am lucky enough to have been there a few times.

We are actually only in Italy for the last couple of days of August, directly prior we will be in Maastricht.

Thanks again!!

171 in an ISF. Car was unbelievably stable at that speed it felt like I was barely doing 100.

I really want to join the 200 club but I want to do it responsibly because I'm not trying to go to jail or put other families lives at risk

so are you saying you did 171mph on a public street?

If I'm wrong, I'd like to learn how it does account for this?

Nothing said it had to be on a road ...
And how many people do you know who find out actual gear limited top speed?
fwiw, car now has about 1,500 more revs to it.

Well, it did say speed achieved, thus implying a road or track...some surface on which you were traveling.

Speed is defined as "rate of motion: such as
(1): VELOCITY
(2): the magnitude of a velocity irrespective of direction.
https://www.merriam-webster.com/dictionary/speed

Velocity is defined as "quickness of motion" or "the rate of change of position along a straight line with respect to time".
https://www.merriam-webster.com/dictionary/velocity

And thus it is the velocity definition, specifically the rate of change of position along a straight line with respect to time that indicates it ought to be along a road / track /etc.

Not a dyno where you are stationary. Which doesn't account for the factors that I mentioned which would pare down your real world speed.

It would honestly just be easiest to admit I'm right.

You can calculate theoretical using the following parameters:
1. Rolling circumference of the tires or diameter + equation.
2. Final Drive Ratio
3. Gear Ratio
4. Revolutions Per Minute of the engine
5. Correction factor.

Here is a link to a calculator: http://www.csgnetwork.com/speedcalc.html

Communism works in theory too.

The correction factors seems to account for wheel/tire size changes. Did not appear to take into account aero (huge impact on top speed), nor potential heat soak if FI, ambient temps, etc. Unless it does, I put very little stock in said calculator. Far more interested in real world results that people have seen.

+1

That formula is mainly a means of selecting gearing to match a target speed. You don't know much about a car's actual top speed unless you can factor in drag, temperature, altitude and the other things you mention - heat soak, etc.

Hence using the term Theoretical.

In my car which isn't aero or power limited, the calculation is pretty accurate up to and through 6th gear.

I'm aware you stated theoretical - I bolded it. I then clearly laid out my thoughts on theoretical speed, leaving little to doubt as to the weight I place on such "speed".

Did you achieve your top speed in 6th or 7th gear?

Hellcat in sig in Mexico. 165 MPH. Just an intake. I decided I pushed my luck far enough

However, I had my old E90 335xi's speedo pegged (Went to 160 MPH) so I was probably going much faster than 165 MPH in that car. BMS DCI & Cobb AP OTS tune. In Mexico as well.

Had an old Camaro Z28 & C6Z close to those speeds as well.

I really wanna do a half mile event

Sorry about the delay. Driving into the office.

I had just shifted into 7th at just under 180 and the car was still pulling hard. My redline is 8400 because of the tune rather than the 8250 of a stock car.

I asked, because I noted you said you felt the calculator was accurate up to 6th and I knew it had 7 gears and wondered if you were implicitly qualifying your statement without saying so outright. It was more a curiosity for me as I noticed the nuance in the words you chose and wondered if there might be something more there.
