Hi all,
I am a new MX5 owner and am pretty sure I just ripped the centre out of the clutch on my car.
It is a 1.8 with a turbo setup on it and runs a Flyin Miata aluminium flywheel.
What clutch do people recomend and what have people used in turbo applications?
Thanks
Jake

The Exide one that's used in the SE would be good. If not, use one from an NB8B onwards and you'll be OK as well. They're used in the SPs.

im running an \"XTREME\" brand clutch its a 700kg pressure plate and a stock disc if you want even more torque capability the get a sprung 6 puck disc instead of the stock disc.

all alloy flywheels I have seen have a bolt in section for the friction part so hopefully it should be alright.
It was running a Kevlar clutch according to the previous owner.
As soon as it arrives at home I will pull the gearbox and find out what exactly went wrong and exactly what the old setup was.
Last dyno tune it made over 160 rwkw, with the mods I have planned I am hoping to lift that number a bit so I want to know that the clutch will handle it.
That said I would rather have clutch slip than blow up gearboxes/diffs.
How much power can the drivetrain handle?

4sfed5,
whats the pedal pressure like on your set up? is it much heavier than stock?
I still want my GF to be able to drive it.

Jake

Your GF drives your 160kw MX5? Surely with that sort of power you start doing donuts if you fart near the excellerator...

Then again, your gf might be Sabine Schmitz... google it if you don't know her.

Boags

Jake, are you the new owner of ca18escort's old car?

Boags,
I know who Sabine is. My gf is a good steerer, knows her limits and has some restraint so I am more than happy to let her drive any of my cars. Wont let her ride my motorbike though

Sabretooth,
Thats the one, got some plans for it already. Nothing too major, just refining the package, change the diff ratio, some cosmetics, prob a new turbo. Though knowing my previous record it will prob be getting a full workover.

Daz,
Cheers mate, will check it out.

Exedy Extreme sprung ceramic puck clutch. They are very good, well priced and should hold 200 rwkw. The factory SE clutch is an exedy extreme organic with kevlar. Not sure about the alloy flywheel either - I'd be going cro-mo for big HP safely. The FM boys reckon they are OK but I'd be fitting a scattershield just to be sure.

CT,
yeah, I think I might replace the flywheel with a cro-mo one given that I will be trying to get a it more HP out of it.
Are there any brands that you recommend?
You wouldn't happen to have a part no. for that clutch would you?
I found ceramic clutches on the Exedy site but none under the Extreme brand.
Thanks
Jake

my clutch feels like stock really didnt notice much difference in pedal effort and neither did my wife...in fact she says it feels better than before when it had a stock clutch....

If youre running over 160RWKW then you should get some sort of puck clutch maybe a 6 puck kevlar. Its not the heavyness of the cover that will make it tricky to drive...it will be the puck disc.

I have dríven plenty of puck clutches before and they don't concern me one bit. Not hard to drive once you get used to them.
Don't want to end up with a really heavy pedal though.
I guess I can always play around with the master cylinder to slave ratio's to lighten it up if neccesary.

I'm running an Xtreme clutches 4 puck ceramic sprung clutch. With a super heavy duty pressure plate.
This is for a 1.6 Turbo that i use for daily and plenty of drift action with the odd track session thrown in.

Cannot say enough good things about this clutch, very easy to drive in a day to day situation and very easy to get super quick engaugements. This clutch has seen its 3rd gearbox in a very short time span. (good old clutch kicks!).
The pedal effort is probably a little stiffer than stock, but less stiff than the previous Xtreme heavyduty organic clutch i was running. The clamping pressure i got was 100-150kg more than their heavy duty (they changed the pivot point) - which would bring it to around 750-800kg i think.

I'm running about 13psi boost and 264deg cams on my stock 1.6 motor, its got a good amount of balls to it so one of these clutches, but in 1.8 version, would be more than enough for anything that is day-to-day streetable imho.

Bought the clutch from the first advertised Adelaide dealer on the Xtreme clutches website, i'm in brissy and these guys were by far the cheapest including transport costs. Think i payed 450-480 for mine.

Hope this helps!

As for cro-mo talk to MX5 Mania who have a great looking one for a 1.8 which is custom made. Make sure you replace the flywheel bolts with factory new items. As for the clutch, the ceramic is lighter than a stock one - no probs there. I will check and see if I have some part numbers at home although mine is the thinner version for race only cars. Exedy do two plate thicknesses, one for road and one for race. You want the road one for the extra heat disappation.

*** mine is a MZK-6964HDB *** which is in the race car. It's actually very light and easy to use. The japanese made ones come in two thicknesses. The above one is made here.

CT,
Thanks again. Sounds like the way to go.
Does anyone know if MX5 mania have a dealer in Melbourne or if anyone in Melbourne does similiar flywheels.
I like to have a look at stuff like that before I buy.
Is anyone else on the forum using the MX5 Mania Cro Mo Flywheel?
