So can you get an RTS setup lighter than a standard pre verto set up??

and Colin, would an AP RTS be over kill on a 1293, gt17, 10 psi, standard head 33/29mm valves, sw5 cam?
thanks

Ah I always thought mine was a valeo, as the other clutch I had, had slightly smaller spring plates and the metal retaining plate instead of the wire ring.

Both of my spring plates are turbo ones, and they both had the wire ring type retaining rings?!


I don't think you can use whether or not the clutch has a retaining 'plate' or not, as to which clutch type of clutch you have, the 'AP' type does not always have that ring, but more often than not the 1275 ones do. I believe Ferodo made an 'AP' type clutch, so its not exactly an AP clutch, but it looks identical, if that makes sense

Basics of it are, if you have the larger OD springs, its an AP type. The spring 'leaves' are longer and noticably flatter compared to the shorter curved leaves on the Valeo, but the biggest give away as to which is which is the backing plate that its all fixed to, as can be seen above.

I agree, the more I see the more variations there are!

But I agree the AP is the one to use,

james Over kill or not I'd go with the RTS, IMO its uch nicer to drive, dosent need adjusting, and leaves room ofr upping the power.

also std Pore vero is circa 10 1/2 kilo's, with the MED back an RTS will be a bit under 8.

It would be interesting to start a feature on different clutch combinations, what power outputs they can handle, cost and the actual purpose they are being used for ie road or race. For most...its the cost...........

Cheers Joe, seems RTS is the way forward!

soon everyone will be running RTS clutches with 6 speed boxes *happy*

No idea

Why is everyone dead set on removing as much weight they can from the flywheel on a turbo motor?! The extra mass in the flywheel will be better used to absorb all the heat and keep it away from the primary gear!

If some one wants to weigh a complete standard un lightened pre verto set up with sprung friction plate, I will weigh my MED light weight verto flywheel with an AP race friction plate and an RTS.

We all know the Verto is a heavy clutch, but then we all know the pre verto with a grey spring can kill your thrusts. If you want a reliable clutch to take the torque, then it has to be the proven RTS verto, but if you want to loose as much weight as you can, you will have to put up with a thrust failure once in a while. There is also the ball ache of clutch actuating mechanism on the pre verto, it is tempremental at the best of times and needs regular adjustment, the verto doesn't. For a moderate mileage road engine, I know what clutch I would use, every time.

Hit it on the nail Colin. Totally depends on what the engine is used for.

Well as I've already got the clutch's rts seemed the most sensible way there both turbo ones aswell but as iam still running a metro with cable operated clutch iam goin to see how long it lasts before It dies & I've got to change over to hydraulic peddle box so that will be interesting to see

Im not sure if this is related, but since changing to an RTS I have noticed significant changes to how well the box components last.

Im sure my baulk rings need replacing again (only done 2 years ago), as its started grinding in 3rd. It only does it at very high revs 7k +, im thinking that maybe the extra weight of the flywheel is putting extra loading on the baulk rings due to the extra intertia?

Does this sound viable..or am I WAAAYY off?

I cant see the flywheel/ clutch causing that (but will have a think on it) the larger clutch plate could as it will have more inertia, TD has mentioned this,

Somthing I hadnt heard untill recently is the 3 springs in the syncro hubs affect how the baulk rings bite, if the springs are weak you can get crunching, I need to check thi out next time I have a box apart.

The flywheel is not attached to the gearbox, but the friction plate is. I see no connection with your problems an the Verto clutch/ flywheel

Its the way you drive it *hehe!* *wink*

I was thinking along the lines that any kind of clutch drag will be amplified with a heavier flywheel as the engine will take longer to slow down.

I assume you will always get some kind of drag with any clutch... or am I wrong again? lol

not unless there is a mysterious magnetic field involved.

when changing gear, the clutch is dissengaged, therefore it is only the inertia of the friction plate that is acting on the synchros.

What Turbo Dave previously talked about is the increased inertia on the synchros when using a paddle plate, or a twin plate clutch.

If the clutch is enaged, it is either in gear or out of gear, and has no effect on the synchros whether the engine is accelerating or decelerating

any clutch drag would mean that the clutch is not adjusted correctly or, that there may be a problem with the primary gear.

just cannot see the relationship of synchro wear and a 'heavy' flywheel

It would seem to tally. As before we stripped the van and had ultralight on we had no box troubles. Since fitting RTS we're getting some graunch on second.

We're going to strip the box to investigate anyway but seems odd that it would seem smooth as a cashmere codpiece before rts and rough as a bears arse after!?

I am however wondering if our RTS wasn't quite disengaging?

Ah so at least its not just me then! Im guessing it would be worse on a dog box, with the dogs trying to engage and the gears not slowing up?

Its fine if you change gear normally, its only on emergency gear changes, driven in anger that it seems to happen. This makes me think something isn't quite slowing down quick enough for the gear to engage smoothly. *oh well*

Robert, have you noticed any difference with how yours goes into gear since fitting the RTS?

I must say, mine is a bit like this too. When pottering around it's fine, but at 7k it does seem to struggle.

Well, I hope it's the case as I then have something to blame my missed gears at the pod on Sunday :)

In the 13's at last!.. Just

nope ,slick as anything at up to 7100
, but the oil i use makes a diff compared to normal oil.
i think its important to do a good few miles to bed it all in,and have it release cleanly.

i had issues like this with my rts, and it was down to the cover nto adequately clearing the plate when the release lever was pressed, rebuilding it with closer attention to clerances sorted it in one instance. and loading it up in boost at a standstill in 5th sorted it in another (was desperate)
