Hi,
I am building an RTS clutch to compliment my engine upgrade.
I've read through the original RTS thread on building an RTS on Turbominis.co.uk and have been watching Stuart Gurr's video on YouTube. And have a few question later in in this thread.
To make an RTS you need two clutch springs, these, from what I have seen, cannot be purchased separately, so you need to dismantle another clutch and use two clutches to make one?
I am using a Clutch Kit that came as part of a MED ST1 Lightened Flywheel set. The clutch is a Borg & Beck.
Looking at Verto clutches, there appear to be different types / builds, the old clutch I am taking the spare spring from (not sure of the make? Pic below) has a flat / edged ring about 15mm wide under the rivets, on top of the fingers, the MED one did not?
It's still has the two rings, one on top that sits under this flat ended ring and one under the clutch spring fingers.
The MED (Borg & Beck) Clutch did not have this flat edge ring, it just has the smaller thin two rings, one under the top hat of the rivet, on top of the fingers and one below.
I have taken both clutch kits apart and the springs are slightly different, the outside edge of the old one has a larger circumference?
You can just see in the pic below, the newer MED spring is on top
The newer clutch fingers sit higher, I guess this is because the old one is, well, old.
Questions:
1. Will these two finger springs work together, or do I need to find another similar clutch (Borg & Beck?)
2. Not sure whether to put the old spring on to or underneath - would it matter?
3. Stuart mentions using Lotcite 571 in his video for the allen bolts to hold the springs on, Loctite 571 does not seem to be readily available, so is Loctite Blue 243 OK. That's what I have been using for the UNC bolts in the Gearbox.
4. Stuart suggests using a sprung friction plate, to aid smoother acceleration? The MED comes with a fixed plate, so, which sprung plates would anyone recommend?
Background
For my 1310 engine build I bought a MED ST1 Lightened Flywheel and Verto Clutch Kit. I then started to consider adding a Supercharger, this meant lots of research to identify what I need to change on the engine from the original build to ensure that it would be suitable for the extra Torque.
When researching clutch requirement, I found out that the MED ST1, was actually only rated for 70lb/ft torque, so whether I added the SC or not, it would still not be up to the projected 85lb/ft torque for my non SC build. So, I needed a better clutch, hence looking at RTS's.
I have searched around and know that the top racing boys etc, get RTS's from 'Pad Jo', however at £750 each, I needed to look elsewhere. I am not building a track car. This is a fast road car that may do the odd annual track day? But if I want to accelerate occasionally, I'd like to know that everything is solid.
