Avenger parts on trademe

[JoKer]

hah nice : all yours

you'll use it more than me

[avenga]

You don't need 5 gears anyway Jared. Most hillclimbs I would struggle to get out of 3rd.

[JoKer]

yup is my theory too

[JoKer]

holy bidding war batman!

ok who's george?

[JoKer]

wow spendy! haha ross you wasting hi money?

[oldschool]

Lucky I got the gearbox cheap...lol

[avenga]

Awesome stuff Ross. I will be interested to see how a 5 speed goes in a standard Avenger.

Now you will have no excuse for not keeping up on road trips.

Let me know if you need any help with the conversion.

[oldschool]

Yes will be good, you know me Richard, I don't like to over-rev...lol
I will need help converting it as there's so much engineering to do.
Will run it past a local firm that's done some electric motor to gearbox adapter plates for me and see what they say.
The photos from your conversion will be invaluable!!
It will be interesting to see what rpm's Scarlett will do in 5th using the standard 3.89:1 rear axle?
I know the Sierra 5th gear is quite tall, so Scarlett may go below the equivalent 3.7:1 ratio of my Chrysler Avenger GLS?
The Triumph TR7 used a 3.9:1 rear axle with a 5 speed box and that was a 2 litre, so mustn't have been revving too high?

[JoKer]

i knew of a rpm table chart/spreadsheet somewhere, you input the known ratios and it tells you speeds etc - will have a looksee

hot glue and zippy ties, just sayin

[JoKer]

found it

Ive built up this excel spreadsheet to as accurately as possible Calculate and Graph Speed Vs. RPM for your vehicle.

Very simple to use, download it here: RATIOCALCGRAPH.xls

Enter in your gear ratios, final drive ratio, tyre size and RPM limit and it will produce a graph showing RPM Vs. Speed in each gear. The spreadsheet is only setup to map out to a maximum of 10,000RPM. This can be used on 1, 2, 3, 4, 5 and 6 speed transmissions, simply enter 0 for your ratio on gears that you dont have.

If you want to see more detailed data, click on the DATA sheet at the bottom of the page.

To find out what your ratios are find your gearbox code on this site: http://www.catherineandken.co.uk/sti/trans.html

I hope some of you find a use for this

obvously from my 'other' forum

[avenga]

FYI here are the type 9 sierra gearbox ratios

1st 3.65:1
2nd 1.97:1
3rd 1.43:1
4th 1.00:1
5th 0.82:1
Rev 3.66:1

That XLS file is pretty much bang on. It says I get 2,800RPM@100KPH in 5th with 185/70/R13 and 3.70:1 diff. With a 3.89:1 that would work out to around 2,900RPM@100KPH.

[JoKer]

maths is a predictable creature!

cool to confirm it with real world application
