:: Top speed, please correct my math

Having sparked interest from the RPM limiter thread, I did a quick calc.

Assuming 6800RPM with 235-45/17 tires, final drive of the e34 535i at 3.64, my theoretical top speed would be 140.9 MPH or 226.8 KPH. Clearing this is wrong as I have done 240 per the speedo before. Is my math wrong or stats?



EDIT !!!

Brain fart. Final drive is 0.81. I plugged in the diff instead. Vodka inhibiting rational judgement. So theoretically at 6500 (safe) RPM in 5th, it can reach 166 MPH or about 267 KPH. Ok. Of course the speedo only goes up to 260

whats the final gear ratio? as in overdrive or 5th gear?

Yeah I've done 240, but only briefly...

The final drive is 0.81. The vodka kept the diff ratio stuck in my head.

i haven't even made 100 mph, i came close (155 kph), but yeah still getting used to driving a car that can exceed the speed limit everywhere without feeling like i am going to die.

dude, ever try to smoke vodka? not a great thing but you can use it in a bong, gives a whole new meaning to bong water...you can drink it!

Okay, drinking bong water is gross as hell.


Water or liquor


Bong water smells really bad and usually has burned residues from the bowl you just smoked.


Come on man! Don't ruin the vodka, mix it with some juice instead...

Just because the speedometer said 240 doesn't mean that you were DOING 240. I read in the newspaper that German cars are notorious for overestimating road speed, and that VW and BMW are the most innacurate. To keep you out of trouble I guess. Rant: People always claim that their fast cars can do more than the limiter (155 mph) but this is not so: only a calibrated testing device will tell you exactly how fast you're going (like car magazines use).

seroiusly try it before defaming it, the vodka keeps the oily residu off the bong, dont spoil and dont smell like ****. try it and then post, ill wait. you can use it to clean used bongs but without heat it wont pull the crus off the sides.
