manual 135i driver's cheat sheet

[professor]

For the geeks out there, something just for fun: train your heel-toe technique to robotic perfection.

[atr_hugo]

Hmmm - with existing gearing you could hit 400 km/h (granted absolutely perfect aero - which don't exist in the real world). But 200 MPH on the salt flats with tweaks? Hmmmm . . .

[Dan203]

You'd have to get the Dinan flash to remove the governor. Otherwise you'd never get above 150Mph. However if you did, then according to that chart, you should easily be able to get into the 200Mph club. Although that is scary fast, not sure I'd want to attempt in my $45K car.

[matt]

that chart is wrong.

max.pos. speed would be 306km/h according to the gearbox.

without limiter its arround 270km/h.

[Dan203]

So no chance of getting into the 200mph club then? Even with tweaks? The transmission just wouldn't be able to handle it?

Someone really needs to brush up on their Excel.

For starters RPM @ 60 mph (100 kph) in 6th is around 2,200, not 1,700 as the sheet says.

And the 7,000 redline in 6th works out to 190 mph (=320 kph), not over 400 kph or 240 mph!!!

With the aerodynamics of the 1 series, you would probably need in excess of 600 hp to break 200 mph. This is purely conjecture as I don't feel like figuring out the math. Nate

I can see it now... a spreadsheet suction-cupped to the windshield! :eyebulge:

[ansun]

Id like to be a geek and understand this. Are those optimum shift points?


Oh, if someone switched this to MPH that would be sweet.

[professor]

these are purely theoretical based on the feed values of the 135i final drive and gearing ratios as well as its redline and peak torque RPM. so it is not meant to replicate real world dynamics (especially at end point speeds as you so astutely note) but works well at reasonable speeds.

...or you could just multiply the km/h by .6214

Nah, taped to the steering wheel wouldn't block your vision. plus its closer to the tachometer:biggrin:

Would you feel safer going 200mph in a $15k, $45k, or $100k car?

The more expensive the car...the safer id feel at higher speeds.

My father in law had a Bentley Continental GT. I felt very safe in that car hitting 180 mph. (Fastest I personally have ever traveled was 185 mph on my Ninja)


...new thread!!! How fast have you gone??!

[professor]

i just wondered how this sheet would compare to the ideal shift points that the performance steering wheel would signal. i imagine the steering may be more conservative.

I wasn't thinking of personal safety. I was thinking more about the safety of the car on the salt flats.

Puts his car's "life" before his own...what a guy!

[UK135i]

how can we convert this so it is in mph...by the way i did not realise Australia did it in kmh i always thought you guys were miles as well

[UK135i]

dont worry guys i have just found a website that can do it for me

[ansun]

put up the MPH!

[Dan203]

Just type it into Google like so.....

338km in miles

it will spit out the conversion for you.

Dan

[sndprssr]

Are you guys serious?!? I just posted the conversion back at post #11. I know that even if you can't do math at all, you can find a calculator on your own. The only way to learn is to do it yourself and quit relying on others to do the work for you...

[Dan203]

I saw your conversion, I was just offering up the Google solution as an alternative because it's just as easy as doing the math yourself with a calculator.
