clutch slip
Turbo Mini Forums

i've done some searching and would like your opinions on something. i had the clutch replaced in my t about a month ago and not really used the car since.

i did ask for a gray diaphram with a road/rally clutch, however sometimes when you put your foot down it either bites or it seems to over rev and act like it did before i got it replaced.

i have been on the phone to them and taking it for them to look at tomorow again but i did ask him what he put in it and i have.

Orange diaphram with a road rally friction plate for late A+.......

now i have 2 questions:

1, can you let me know what you have in yours.

2, he has this is his pick up thats got 146 bhp and supercharged and it works for him?

the general engine set up is: (sorry i dont know power output)

new built engine,metro turbo block bored to 1293cc,new omega pistons 5mm dish,standared turbo crank,new mains,new bigends,centre main strap,new high pressure oil pump,big vave head,polished ported,broze guides,new double heavey duty valve springs,standared t3 turbo,new avonbar 13 psi actuator,newavonbar dump valve,new avon bar 10 psi carb needle,new 2" avon bar down pipe,new group a silencer,rs turbo inter cooler front mounted,new hell oil cooler with braded hoses,new turbo clutch,recon turbo gear box with cenre oil pick up,duplex timing gear,standart turbo cam

i'd guess he's not got a genuine 146bhp or absolutely no torque.

He'd need a minimum of grey with either an organic or rally plate in. I have a paddle as i'm thinking even those wont hold up to the planned output.

so i need him to replace it with a grey one then...

i'll chat to him tomorrow

yeah i was thinking that but meant go down the non-verto route

rushing too much to asnwer!

na its still an old style clutch arm verto i think(the nice one not the annoying one) i honestly don't know what he meant by that as you can prob tell my knowledge on this is pretty basic was kinda hoping you'd know but as you dont i'm worried now

i think he may have just assumed that cuase his charger pick up has it it'll be ok but dont the turbo give more torque than a charger, well in a smaller space of time?

something's not right here...

Yours should have a long clutch arm with the slave cylinder mounted directly onto the transfer casing and acting "inline" with the crank.

The verto has a short clutch arm, has a slave cylinder mounted on a steel plate working at 45 degrees to the crank in effect.

I would be very suprised with that power if he's running a verto.

also if he 'has this in his pickup' and he means the orange diaphragm , then it cant be a verto either...

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

all very strange this, i shall be asking lots of questions tomorrow...

well i had a water pump gasket go on me when i went to take it last week but got there this week and chatted to the guy and well apparently i got an a+ clutch (being verto) but with the arm set-up of a pre-vertro?? can that be done??

well think i just need a pre-verto flywheel and clutch then it should be fixed, but is it possible to have a pre verto clutch arm with a verto internal??

this would probably be why it is slipping as apparently the a+ preverto isn't as good as handlign power?

T

If you have the long arm, you're pre verto. If you have the short arm, you're verto. No ifs. No buts. Plain facts.

You cannot use the long arm on the verto, as the clutch wouldn't FULLY disengage as the plunger isn't moving enough; and if you tried the verto arm on the pre-verto you'd need legs of arnie, and it'd only need around 1.5" total movement at the pedal.


The Verto Turbo diaphram should be capable of a typical 10psi engine build with the AP race/rally friction plate.
The Pre-Verto with an oragnge diaphram will struggle to achieve what a healthy 'verto turbo' clutch can. The grey will exceed the verto turbo - even more so if the backplate lug height is optimised.



I think you need to take a step back and review just how good this mini centre REALLY is... They sound like it's just one line after another to me...

hmm so it can not be a mix match then....

well tbh i'm a bit lost remind tonight to do some reading up on clutches.

think i'll give him a call now find out whats happening with it.

quick edit and question are the housing cases differnt on teh two cluth styles?

T

Edited by t@z on 18th Sep, 2006.

just the arms and plungers(?) and release bearings i think, the housing or 'woks' are interchangable

*edited to add*
generally the verto setups dont have the window at 12 o clock to veiw the flywheel timing marks (as its a different style flywheel)

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

as far as i remember the two housings are the same, both of them have the fixin points for the verto clutch, but i mayb wrong.

it may b small but it purfectly formed

well for all your ref the mini place is palmer bros and they seem ok, nice guys. he has got it out atm and looking at it i have asked him to go back to the pre- verto set up for ease and simplicity for me in the future. said let him get it out have a better look and he will call me.

confusion at its best, and a very weird clutch set up?

not his fault its how i got the car.

T

well my cars done, hopefully get it back next week sometime and i cant wait to drive it. before it was quick, well for me....now i get the feeling its gonna be super scary.

the guys at palmer bros did a great job, said its a bit of a mish massh with the clutch, so has restored it back to pre verto for me with no expense.

wish i could take it tomorrow but maybe next year.

T

well tbh as long as its running pre verto set up internals work it dont slip blah blah blah and the rest it'll do. he said he put and new ap racing fly wheel on it and a grey diaphram etc etc.

he didn;t charge me i guess cause probably it maybe shoudld have put it to the original spec to begin with i dunno.

i works and apparenlty it now boosts. if i get it back and it dont ill take it back.

T

well taz - it has the grey, so hopefully your problems will be gone now :)

i can but pray, everytime i think this car is fixed something pops up

still hopefully not it is just the inside that needs tlc
