Post by danielsperry89 » Thu Jul 12, 2012 10:36 am

hi all i am running 220 bhp on my turbo engine and my clutch has lasted less than 500 miles so i am in need of a performance clutch but mine is the later engine with the 215mm clutch i can not found a permanence or paddle clutch in this size, i do have a 200mm flywheel can i change that from my 215mm flywheel ? or where can i get a good cheap clutch that can handle the power

Can anyone help with this. The main thing I need to know is can I use the 200mm flywheel on my engine even though it's got a 215mm flywheel fitted

Firstly well done in getting 220bhp ,I had 290 in my MGB V8 power is fun and scary with no grip.

Anyway flywheel size I would guess that they are not interchangable. The first problem I can think of is that the ring gear size would also be different so starting it would be a problem as the starter would not engage. If things are stripped down you could have a check to see that all engages and also that when installed, the clutch cleared, it was not not was dragging, slipping and worked correctly, though I do doubt it.

I am not saying that this would be impossible but there could be easier options. .

Now the Volvo has a Renault engine and those silly fools do a lot of tuning so how do the parts compare to those fitted to the Renault? It could be an idea to contact a company that deals with modding such cars to see if anything is interchangable and pick their brains as they might have already overcome such problems.

The next option is a clutch and gearbox specialist. It's possible that many of the parts could be interchangable For example it was rumoured that the friction plate on my Lambo was the same as that used on the Essex V6 though I havn't proved it. Yes I know that rest was different but that part was the same and lets face it, it is easier for a manufacture to select off the shelf than make their own. No it wasn't up to the job, 30k average life so I suppose good enough.

Such a specialist would be able to advise on what they have that could handle the power or at least how to go about it. This could get more involved as they may need to redrill the flywheel and machine parts as required if things do not match up so prices will go up accordingly, but it only costs a phone call to enquire.

I know it's not the cheap quick fix but hopefully of help.

Good luck

Regards

Simon

Do a search on clutches this question has been answered several times . felyx has posted up details on the forum including where to get the clutch done (not that expensive) .

i think the starter is the same for both flywheels,

i had a read on his post and i have called up friction services up and they have said they dont think they can help me so thats out the window i have seen a paddle clutch on the net but its for the 200mm flywheel not the 215mm thats why i was asking if i can swap the flywheels

I am still doutful that things will line up.

Unfortunately when the starter engages it drives towards the ring gear and then spins so unless there is a way of compensating for the loss of 15mm in how it is fitted, I still think it would miss.

The starter motors may be the same but I assume the their position in relation to the flywheel would also be different depending on the flywheel fitted.

Checking online confirms that both the 200 and 215 clutch was fitted to the 1.7 so I am guessing that the 215 was fitted to the turbo, was there also a difference in its mounting point to slightly reposition the starter?

Also you could get in touch with the person with the clutch and see if they can tell you what are the differences with the flywheels other than size. If things are drastically different can they machine your 215 flywheel to accept it?

I think the Clio Ph2 RS had a 215mm clutch so this could be a upgrade for the later 480 boxes as well.

Both 200mm and 215mm clutches use same diameter flywheel and I think the timing teeth are the same. There will be no problem with the starter, its not the diameter of the flywheel he wants to change that would achieve nothing.

215mm would be best for handling power. Like Ettore Bugatti mentioned look for the Renault clutches as they should fit fine. Helix made one for the Volvo I think but expect to pay the price.

The earlier 200mm flywheel is smaller in diameter to the later 215mm diameter flywheel trust me I know this from experience now... I've got 2 black diamond stage 2 fast road clutches I used the 215mm as it is noticeably bigger and my flywheel was 215mm obviously but yes I agree more friction surface, more friction, less slip... it's an obvious one. Personally I'd inspect the flywheel exhaustiveley for hairline cracks and lips etc... before fitting a new clutch it would have to be spotlessly clean. I'd recommend a flywheel skim with what you're running. I was running 200bhp on mine easy... if it's not all clean and mating up sweetly you will get slip and then glaze the clutch over... then get tonnes of slip...

But yes both clutches are for sale. 215mm has approx 700 miles use and will last yonks regardless. And the 200mm is brand new in the box. Cost me 550 for the 2 guess which one was dearer.... yep the bigger one... anyway I'm hols so catch ya later ;)

This is not meant to be an answer to the original question, it is to prevent serious Volvo 480 members/readers from drawing wrong conclusions.
The only difference in flywheels is the location of the mounting holes and dowels for the clutch cover plate and the diameter of the friction surface.
Stating BHP for clutch usability is not very practical, the torque is the thing to withstand.
The standard Volvo 215mm cover plate is sufficient to hold well over 250Nm. Stronger springs will only be found in racing material. The friction plate however is pretty hard, intended for long life, thus not having optimal grip. Renault Clio (Williams) and Laguna have similar friction plates covered with softer material.
The ideal way to go from a 200mm clutch is to fit a 215mm type flywheel. Machining the 200mm flywheel to fit the bigger clutch means centering the clutch, drilling holes and grinding the surface to remove the wear of the smaller friction plate. Quite some job.
