0 to 60

[blimmer86]

does any one no how fast a 2.0i e30 does 0 to 60 in
cheers

[Sjoerd320i]

the book says 10.6 sec

[Zayyan]

You could get a G Tech, then you'd know the 0-60s of yours and your mate's cars (that's why you wanna know isn't it? ) pretty accurately

Did you reply to my last PM by the way blimmer, my Inbox was full, sorry

[Andy_magic]

I did a few 0-60's in my 320i and it worked out at 9.2 average, but my car has 183k miles on it and loads of weight in the boot due to loads of tools, a massive sub and loads of dynamat type stuff.

My 2.7 project is underway so I'm hoping to shave a second or 2 off that time

[Zayyan]

Andy is that using a timer and the speedo though?

The speedo overreads quite a bit, especially with those standard-sized 15" (?) wheels you have

[Andy_magic]

Ha ha..
Those smallish looking wheels are 15" BBS with 205/55 tyres on 5 mm tread. (I see you just editied your post)

What I did is I drove at 60mph speedo reading and kept it there and reset the OBC speed thing. This gave me the actual speed and was slightly under, I then drove at 62mph and found the OBC (Once reset) was at 59.9mph.

I took the 62mph figure and timed it with a stop watch, did 10 runs 0-60. I averaged it out and got the figure.

So it wont be as accurate as proper timing gear but I would say thats it's as accurate as a g tech.

What I meant was that I thought the speedo overread so that if you put non standard (i.e. bigger) wheels on it won't underread

That's a good way of measuring though, and very good times for a 320i!

All I need to find out whether mine's over 15 seconds or not is an OBC

[Andy_magic]

The only problem with forums is what you write doesn't always come accross as you meant it.


I didn't really understand the last part of your post above.

As long as the rolling radius of the wheel tyre combination remain the same as standard wheels/tyres you wont be too far out.

If you retain the same width tyres (IE 205) and go up an inch, you drop by 5 on the profile)

So say your running 205/55/16 to keep roughly the same rolling radius you would fit 205/50/16's. there are loads of tyre size calculators out there that are more accurate than that method, but it's good as a rule of thumb.

For those not in the know, the 205 bit is the tyre width in MM the 55 bit the hieght of the tyre shown as a percentage of the width (55% of 205mm) and the 15/16 bit is the size of the bead (I'm pretty sure everyone knew that )

I can't be sure how fast my car is but I got 6200rpm in 5th today which I didn't think was too bad.

[Zayyan]

Ah, I see what you mean about the tyre sizes

I guess the speedo just overreads as it's a bit crap then!

Hitting the limiter in 5th?

What did the speedo say?

[Andy_magic]

It was showing 128, the limiter on mine is at about 6700 so it was a little way off hitting it.

320's have bugger all torque bit they rev really nicely as they are really short stroke.

I'm sure I read somewhere that the speedos are more inaccurate at slower speeds than high, or did I get it round the wrong way.

However fast it is, it's not quick enough

[Zayyan]

However fast it is, it's not quick enough

Good quotation that!

I would've thought the speedo'd be more inaccurate at higher speeds; if you presume there's a certain percentage of error it'll obviously be a higher error the higher the speed.

The way to go would be a sat nav system that shows your current speed, accurate to within 1mph however fast you're going!

[Andy_magic]

I reckon your right about the sat nav bit, a mate of mine's got an alpine one sitting in the house.... MMMmm Alpine

320's have bugger all torque bit they rev really nicely as they are really short stroke.

im pretty sure its the same stroke as the 2.5 but a smaller bore..

[Andy_magic]

Oh,

I thought the 320 was 80x66 and the 325 was 84x75 and the ETA 84x81.

[Jhonno]

whats the cc displacement of the 2.0? 19...

[320Touring]

whats the cc displacement of the 2.0? 19...

1990 cc iirc

[Jhonno]

many apolgies dude - you were right, i was confused - the stroke and the bore are smaller on the 2.0

[Andy_magic]

whats the cc displacement of the 2.0? 19...

Wholly inadequate!

I think it is 1990cc - whatever, it's just not enough! Does sound nice though.

many apolgies dude - you were right

[astondg]

I think my 323i would be very lucky to do 0-60 in 9sec. Actually I think 9sec is the figure I have read in road tests for a standard 323i. Mine is modified but still doesn't feel any quicker than that, gets left behind by everything.

I' m sure I've seen 8.8 secs 0-60mph in Autocar for the 320i. I thought the 323i was 8 dead....e21 shape was 8.3... (143 vs 150bhp)
