Any reccomendations? To be used with a 2.0 ZVH with a big bearing BC box.

I've been trying to hunt down a Focus RS setup recently with no luck. Can anyone confirm that it would fit in a BC box's bellhousing anyway?

 

Nothing bigger than 220mm will fit IMO.

 

Focus RS setup is 240mm...

All you need is an AP 4 paddle (220mm) with a standard rs turbo cover for that kind of power/torque.

 

AP 4-Paddle with standard cover??

I've used the heavy AP cover with their paddle plate at 300bhp and so has Tony and neither lasted very long. AFPMSL at using a paddle plate with a standard cover!!

The Alcon 6-Paddle complete kit including cover only just holds it, but they are no longer available.

Remember mine and Tony's are only 1600cc too, so less torque most probably.

Good luck I say.

 

What would be the point of using a uprated clutch with a standard cover/pressure plate?? The whole reason that uprated clutches are heavier is because the pressure plate is applying more pressure so it doesnt slip, if you dont have that you may as well run a standard clutch!

 

Christian and Beccy- All I can say that people that are considerably more experienced than yourself use this package with no problem.

 

^^^That man speaks sense!!!^^^

 

I can imagine that the world is full of people that have 350bhp RS Turbo's or have had an RST for almost 10 years.

I never professed to be the most knowledgable person, but I do have a bit of experience and actually happen to think that most of the so-called 300bhp RS Turbo's of the past are bollocks anyway. (save for the current proven cars that is).

 

We weren't talking about 350bhp RS turbos, we were talking about 2L engines, inparticular the ZVH which has typically higher torque figures than a 16v engine at a given boost figure (not particularly scientific, but it'll do for this).

I am not discounting what you have achieved. You seem to be one of those of trial'n'error types where spending 10 years (like you say) tweaking will net you the result you want. That's great, 50% of the worlds achievements are done like that (citation needed )..

However I do find that whenever anyone posts anything that you don't agree with you poopoo them as if you're some kind of RST god.

My recommendation above is based on engines that have been mapped on engine dynos, placed in cars, setup/map_tweaks and then successfully run with the aforementioned the clutch package for many miles. Anything I say is based on either my own personal experience, or experienced I have personally witnessed - certainly not conjecture!

 

All I was referring to is that if ZVH's make more torque, then a clutch that a 1600CVH owner wouldn't dream of using, doesnt stand ANY chance of working with a ZVH.

Im expecting 300lb/ft tops with mine and am concerned about the lack of choices at that torque level, let alone the torque you'd get from a ZVH at 300bhp.

 

The idea behind this is that you get more grip with the 4-paddle as you are using the same pressure from the cover but over a smaller area (the 4 paddle areas) its hard to get your head round but thats how it works

 

in my old zvh i had ap 4 paddle with standard cover that worked a treat. with the ap cover it was a bitch to drive i would never have one of them on an 4 paddle again. the same goes for fayes zvh and oilles black top stranded ford cover for any ap 4 paddle.

 

Yes of course! Didnt think of that!

 

How would it be less prone to slip if a standard pressure plate was used?
I can see that it would make the pedal lighter, but surely there will be less pressure on the plate, hence more chance of slippage?!

Anyone ever tried anything bigger than a 220mm clutch? If so what fitment?
Or is there really no chance of anything bigger being squeezed in.....?

 

hi

a twin plate clutch might be your only option on a bc box, like christian said a 300hp 2.0L will have huge torque no way would a single plate 220mm clutch be up to the job, the clutch will definatly slip been there done that.... not a cheap option but its a fit and forget option the clutch will have to be converted to hydraulic and your flywheel has to be machined down. i run this clutch on my 2.0L zvh.

thanks sean

 

Hi Sean,

Looks interesting! Who does the twin plate clutch, or what application is it originally for?
How expensive would it be likely to get going down this road?

Cheers!

 

you can purchase a twin plate from either ap racing or helix i use a ap racing cover and helix drive plates cover is around Ł350 plates Ł180, the release bearing is slightly different to a normal release bearing see martin at reylands for this Ł60 for the bearing, the flwheel will have to be machined down with a step for the plates again reyland could do this i paid Ł230.
the clutch operation will have to be converted to hydraulic.. i run a pedal box so was'nt as much of an issue changing over, and run a wilwood pull type slave cylinder the clutch would be so light, reyland could possible do the whole conversion for you...

one other thing due to the heavy springs on the pressure plate this clutch can handle 500bhp the clutch wore out my thrust bearings which in turn damaged the crank, the zetec engine only comes with one thrust bearing so i had my main cap machined to take another thrust bearing..

thanks

sean

 

May as well add my 2p worth..

I run a 4 paddle ap with the ap uprated cover, its not the most friendly clutch!
It does hold the power/torque ok except if I'm being abusive with it in second mainly...

I did explore helix option, even went as far as getting the clutch and a billet flywheel however it fouled the gearbox so needed more work on the flywheel to get it all to fit, a job for when its next apart.

 

hi ade,i used 220mm ap clutches all the time before mtx mod,never had no trobel and that was with 260@wheels, part no is 2015-8 tell them u want the ceramatalic kit.

fook trying to keep 300 ponies to the front wheels on the road... mine is pushing around the 220 mark and it is a bitch to keep in a straight line in the dry.... in the wet it is undriveable (when planted)

300 horsepower? goodness gracious you best put 4 wheel drive system in or make sure you have a spare pare of underpants in the glovebox... good luck and make sure you post a vid on youtube when she is running sweet!

 

A lot of good info and experiences there guys, thanks for that


It'll be by no means the first to be running that kind of power..... Most powerful one I know of (and have been a passenger in) is the Sitech Racing S2 which is running about 400 just now.
A handful yes, but it gets the power down, so hell why not?!

 

fair play if it can get it down then by all means.. i was just thinking of this guys wallet and potential cost issues if it all goes wrong.. there is so much to be said about a quick car and learning how to drive it at say 200 horse and a mental quick 300 horse car and not learning how to put all the power down... things like feeling the boost in when coming round bends and just knowing how the car behaves..
I pretty much know what to expect from 220 horses and in my experience is way quicker than i could have ever imagined... it still scares the shit outta me when i plant it and it is relatively low bhp figures comparitevely... but i can drive it alot quicker than my mates who throw out very very high numbers on the rollers... I prefer to have a car I can handle and know how to feed the boost in rather than spending some time in my garage... building a monster engine and then wishing i hadnt when it pinks or i wrap it round a tree... just my opinion and know that in a few months time down the line ill be after a zetec turb myself.

 

that sitech turbo looks awesome btw.. i bet it was an experience being passenger in that thing!
