Technical Pete's Cinq Thread

[fingers99]

If it is the battery (and it's not completely fubarred) then a jump should get it going. Simple check before you get your hands dirty.

but its got really short gears being as its a 6speed

ah the Punto 6 Speed not 60!... fair enough... and it's not REALLY low geared once you put on 195/45R15 tyres, but it's still low.

Gear	1kRPM	5.5kRPM	6kRPM
1st	3.7	20.2	22.1
2nd	6.0	33.2	36.2
3rd	8.8	48.4	52.8
4th	11.6	63.9	69.7
5th	14.4	79.4	86.6
6th	17.5	96.3	105.1

I like the 6 speed with the cento sporting final drive on 175/50R15 or 195/45R15 tyres, it basically puts the 5th and 6th equidistantly away from the normal 5th gear.

	    Speed
Gear	1kRPM	6kRPM	Drop on change
1st	4.7	30.4	N/A		
2nd	7.7	49.9	2,485rpm
3rd	11.2	72.8	1,995rpm
4th	14.8	96.1	1,539rpm
5th	18.4	119.4	1,239rpm
6th	22.3	144.8	1,114rpm


CS5th	20.0	130.0	1,657rpm

and for the record 5th on a cento sporting with the same tyres is above, 4th is the same on both boxes.


Edit: opps looking at the wrong ratio set... real 6 speed numbers now

I seem to remember a thread a while ago that sort of touched on this.

Something to do with less or more teeth on one of the drive sprockets on the diff (I think) meaning in some combinations it results in gearing down.

It was one of David's post iirc but I can't find it at the Mo

 

[StoneNewt]

Cento sporting final drive 15:58, Punto 6 speed 13:64

I enclose a slightly crude (but effective) spreadsheet, formatting might be off but the important bits work.

GOOD NEWS

got home from work tonight and saw the weather report, it said it was gonna rain all day tomorrow (my day off) so i thought "**** it" and went and fitted the alternator now, in the dark

ITS ALIVE Starts perfect every time now and no battery light now Also replaced the weedy 899cc battery for a proper "sporting" battery that i had lying around in the garage from a few cinqs ago.. amazingly it still had plenty of juice left in to start the car

some bad news though, i took it for a drive (timing is defo slightly out, it drives a little lumpy and idle is off) and **** me, the brakes are useless! foot to the floor and its braking like ive just pulled the handbrake up not good!

Also the front tyres are bald.. very very bald! Havent checked the rears plus theres the front passenger wheel scrapes the gear box on about 3/4 right lock which is an MOT fail

Pete, i hope uve got some money to throw at this thing...

 

[Bushboy]

Ok so I got a spare day today so decided to tackle some more of petes cinq


Here she is, notice a new addition that I added out of the kindness of my heart (plus i promised pete he could have it ages ago)



Strutbrace! Woo Might help to stop you from rolling this one Pete!

Next on the list was to remove and replace the leaking coolant hose, so off came the bumper to drain out all of the "coolant", more water




here is said dodgy coolant hose which had been bodged temporarily.


Now replaced with a nice "nearly new" hose

Also I think I mentioned last time that the brakes were crap. So i decided to get the wheels off and have look... My initial plan was to just replace the pads with some "nearly new" Green stuff pads as Pete was told his were completly worn...


These are the old pads, look completly fine to me, almost new thickness!

But I replaced them with the green stuff pads regardless


I took it for a quite spin around my road and the brakes are still usless.. pedal sinks to the floor etc with hardly any braking power. Defo needs bleeding me thinks. The hoses have been replace with some braided jobbies in the past so Im thinking that whoever did it didnt bleed the brakes afterwards...




Just a few piccies parked out in the road look mean :devil:

Still more work to do but it can wait for another day now Pete! get those wheels to mine

 

[dave]

not got leaking rear wheel cylinders has it?

you going to get rid of that hot air induction?

 

[serin]

Oo, this is making me like the car again

the picture without the bumper looks quite cool actually

ta bushboy your a legend :worship:

and the indution is staying hot air, unless your gonna buy me a new one

 

[Bushboy]

well ill fit one of the standard ones i found in the boot on for the MOT

 

[serin]

the k&n should pass, as it has an oil breather pipe with it (shoud do somewhere :chin: )

also, you left something hanging outta the boot

 

[dave]

looks like a sock

 

[mase]

master cylinder maybe?

 

[Bushboy]

yeah its possible.. hopefully its not... worth bleeding them first though

 

[dave]

yeah its possible.. hopefully its not... worth bleeding them first though

that not a hint is it?

 

[Bushboy]

well seen as your offering dave

nah ill probs get one of those kit thingies and have a go myself first before i come begging to you again

 

[dave]

dont forget you need old cinq fluid cap because the ones with the kit no fit propperly. that why it flew off

 

[serin]

master cylinder?

whats one of them? and more importantly how much and how hard are they to fit

 

[Bushboy]

dont worry pete Ive got a spare

how to fit it is another thing, ive no fookin idea

 

[serin]

dont worry pete Ive got a spare

ah joy

hopefully it wont be that then

 

[Bushboy]

nah ill work it out, plus ive got a haynes anyway and its in there... its just the brake system will need bleeding after that too
