Ive always wondered what top speed I hit on my little private straight... My car does 3800rpm at 60mph. But I can get it to about 6600 rpm in 4th till I run out of road.

we have 130km hour speed limits only a few minutes out of town, my backyard is the desert atm. Car sits comfortably on 130km/hr about 4000/4500rpm, except in summer can get a bit hot and need to back off to 110 to let it cool down. Sit on 160 quite easily, but damn its noisy listening to the motor whine like a bitch.

Aerodynamics is probably the biggest restriction to top speed in any car. But ALL minis have terrible aerodynamics. A rover mini has a CoD of 0.48, and a clubby has about 0.53, I think. Little difference.

A clubby won't be able to get as fast as a round nose of the same spec, but you get the extra bonnet space to fit more power!

The engine is irrelevant, its all in the gear ratios.

You want an engine that revs as high as possible that pushes the highest gear ratios and then the highest final drive with the biggest wheels.

Simplify and add lightness

you have a 3.44:1 diff ratio, and on 165/60/12 tyres you should be doing 62mph at 3800rpm, and 108mph (180kph) at 6600rpm

Strap an Emirates A380 to front of the mini?????

Ahhhhhh,,, but this is not quite the case,,,

it`s all good in theory but just doesn`t happen in reallity

it`s all good & well getting a high reving engine,,, & it`s all good & well giving it really tall gears,,, but the poor little things just dont have the """"Power""" to pull tall gears

if you put a 3.4 f-d into an "S" ((((& lets make it a good "S" for arguments sake,,, lets make it a 1415cc stroker with piles of good gear inside)))) Now run it as hard as you can for as long as you can,,, lets even make it down hill...... yeah???

Now fit a 3.2 or a 3.1 f-d into it,,, i doubt it will make it much faster top speed, Maybe a tad,,, (Barely a tad if you`re lucky)

but now lets fit a 2.9 f-d into it,,, i """"""""guarantee""""""" it will not be as fast,,, it wont rev out & won`t have the power to push that tall a gear ratio

simple as that

BUT!!!!!!!!!!!!! if you (Magically) threw more power at it, then maybe it will make a tad more top speed,,, even a turbo or something will help it,,,, but it will "HEAPS" more to pull that tall a gear

the fact is,,, you need BIG """GRUNT""" to pull tall gears,,, without the GRUNT (& lots of it) you just won`t get there

Without the revs, ,, , , you just won`t get there

So,,,,, you need both power to pull the gearing to be able to get the revs,,, & of course the engine needs to be able to rev hard too yes,,, but it`s the Grunt "Coupled with" the abiltiy to rev with such a tall gear ratio to make it happen & minis just don`t have much GRUNT

Most minis on the planet (even good quality race minis) just don`t have enough GRUNT to get past 130mph

& most hot road minis will NOT get past 115mph

No offence intended here but--> anyone writing a book about minis 30 years ago may not have experienced such worn or stuffed-with components as we are finding these days.

You should put your heart & soul into everything you do.

case in point, GR's group Nb car with a 3.765 diff can do 8300rpm along the main straight at Eastern Creek, on 165/70/10 tyres - 200kph, or 120mph

Wow how did you figure my diff ratio out??? Thats correct by the way!

But my tyres are actually 165/55/R12. How does that effect things?

I know my 1275LS at top speed used to cause the top of the doors to part so far from the body, you could stick your fingers in the gap!

On Mt Arrowsmith stage in Targa with a 3.7 diff and 10" wheels we had to keep backing off to stop the motor from going bang, the speedo was pointing to the odometer and the revs were big! So the top speed with this combination comes down to how many revs you can pull and how long it takes before boom!

my mini will do 110kph in a 110kph speed limit and on a bad day (school day ) it has been known to do 40 kph

that's the only diff ratio that gives 60mph at around 3800rpm - 165/55/12's give exactly the same rolling diameter as 165/70/10's - 174kph, 104mph.

So how many forklifts do you overtake on an average day??

BTW, nice sig, damn good car that one

i over take quite a few forklifts in a normal working day
and my sig is trying to let people know this car HAS BEEN STOLEN and to keep a eye out for the bits and pieces

I have seen over 8000rpm in our race car on the main straight at Phillip Island, with a 3.7 diff. And yes, I backed off at the first turn!
