no idea but I heard of that same engine in a Mini getting to 60MPH in 3.2 secs

I think you will find that Laurie Stewart in the Broadspeed Mini did 130MPH down conrod, and that that is generally accepted as the top speed achieved, under racing conditions, in Australia, for a normally aspirated, A Series Mini

wel for myself i can say i have top out my speedo so thats around 160 not all that accurated but the needle was past 160 sitting on 5000 rpm
mind you i got on the m4 at emu plains and didnt reach that speed till about st marys then took me till wallgrove rd to slow down
it was crazy but i had to give it a go

cheers bob

ummm...what diff would you be running to get 160kph at 5000rpm??

As said most Smiths speedos are hopelessly optimistic, Cooper S one was best of a bad lot.
I once wound my `61 850's to the fuel gauge, downhill....

That wasn't a mini, it was a bike with a lot of fibreglass that resembled a mini!

Talking to Graham Russel, you will learn why he builds motors for torque. the difference between 121 and 123 mph was 10hp ie 140hp car did 121 mph and 150hp car did 123 mph, but because the 140hp car had a flatter torque curve, he was doing better lap times. also the difference between 140hp and 150 hp is about $10k, discounting the initial development costs to work out how to get 150hp.......

the relationship between hp and top speed is to the power of 2 (ie there is a speed squared term) so you achieve ever diminishing returns by increasing hp. better to reduce drag (deseam, roof chop, body chop, narrow tyres) than increase hp, if top speed is your goal.

It was a pleasure ausmini. I'll miss all you misfits and reprobates

harley we shouldnt get into what makes a mini a mini. its like the chicken and the egg.

The Suzuki Hyabusa motorbike only just does that. I can't see it pushing a Brick to the same speed

At 300+ km/h you need an extra 6kW for every 1 km/h. Thats why the 'Busa is so long and low. Easier to improve the aero package than more power.

Harley you're absolutely right.......

and

1970 Mini K .... I agree totally IMO if it looks like a MINI outside its a MINI mightn't be a "proper purists" MINI but it still a MINI. =P

anyways saying that you could beat anything with a setup like that on and off the track if the geometry was setup to compensate for the excessive power.

Very Very few Narurally aspirated race minis will do more than 122-125mph FACT!!! (unless maybe there were 3 or 4 of them in a row, right up eachothers backsides, slipstreaming eachother, then i`d say there`d be a tad more top end avaliable, but not much more)

I had mine up to 122mph on many many many occasions (measured on Dave Owens radar gun) & i know there was more to go,,, just that it didn`t actually want to go past the wind resistance thing,

"""IF""" there was some drasitc measures taken to alleviate the wind drag/resistance due to the body shape of the mini,,,(Monaco/Broadspeed/Marcus/Gem/etc) then we can talk more top end speed then...But if it`s pretty well a stock mini body & no massive turbo with 500hp etc, then i find any anyone who says their mini does more than 125mph is most probably talking crud

sorry, but i`ve been doin this for too long,,, GR has also,,, listen to the guys with the results on the board & take notice of them,,, Pub torque is cheap talk

However, in saying all that, i would like to test the top speed in my 350hp turbo charged alloy V8 powered mini that would be interesting & i`d bet it would actually do a fair bit more than 122mph

Paul Gulson claimed super fast top end speed from his old rotary powered brick of years gone by, but hey,--> """The older i get,,, the faster i was"""

me saying 160 thats 160 kph not mph there would be no chance of 160 mph
i think a few people were taking them in the wrong reading
smac i dont know as far as i know its a stock diff
im still knew with the technical side of it so couldnt really say

cheers bob

i was doing 170kmh on the dyno which is zero really but it was just an example of speed v's
rpm. i wasnt saying it would do that speed on the road id be dreaming to do thatspeed,(maybe down a big hill)

_________________
i like to drive on rails

even miniworld is realistic about the top speed, they featured a green, mid engined , nos'd 440bhp ford engined monster a few years back that was geared for 170+ mph, but they did say that aerodynamics would kick in arround the 150 mark.

but does it really matter? nz super mini's lap record at puke is 1.08? i think the v8 supercars are about 10 seconds faster, now really, a million dollars, 600bhp, and 40 years(questionable!) development, i think the mini stacks up pretty damm well!

speed costs....how fast do you want to go...

Several years ago my old clubby beat (by only another 14kph and it was the absolute limit) that but it was with a long runup . It was 1310 , 731 cam and 45 webber , straight through exhaust with a 12" hotdog muffler and 3.2:1 diff . 184kph was the absolute limit it could do out of 3 runs , you would need a really wild level of trim to go faster though I'm sure with the modern cams (RE13 for example rather than 731 and a race head instead etc ...) and the like it's possible but seriously , where are you going to use that speed .....


Disclaimer , I do not endorse speed runs on public roads , it's one of the benefits of working in civil construction , we got to play on freeways before they are open . We had concrete jersey kerbs blocking each end (to keep others out , there were spotters with radios on the other carriageway) , and a decent theodolite to set the 400 metres we used for the timed runs . We used a 3 kilometre section to build up speed (slightly downhill for the first kilometre then flat) and another 2 kilometres afterwards to slow down . The mini definitely wasn't the fastest but it kept a lot of others honest .
