I think just stage 1 map now for me then or have the torque capped at 250ftlb if im gonna up end spending £3k or more I will be better off seliing mine and buying a stage 4 car allready done for me.
Where did you get the £3k number from ?
A Helix 4 or 6 paddle clutch plate + cover + release bearing is just £540 in total. Fitting it should not be more than £400 (I think DuncanVxr fits them for £300). So all in, less than a grand, unless you have a blued/gouged flywheel which is just another £200.

Yeah what I was thinking was the additonal spend over stage 2 if you like. Having a stage 2 remap is likely to take over the 250 ftlb mark and into new clutch territory which is gonna cost another grand in real terms on top of the stage 2 cost.

Looking at full miltek and remap or stage 2 if you are that way inclined and was reading into the regal/eds software. The eds site seems to think that 04 on models have a weaker clutch and cant handle more than 360nm about 250 ftlb.
IMHO as the clutch presure plate is the same throughout the let range, I find this hard to believe.
The only change is the clutch disk plate which was probably modded for other reasons than they are suggesting.

NB this is chassis relevent rather than year.

Well I cant find anything about different clutches either. Im also taking Regals figures with a pinch of salt they seem very optomistic to me.
However im thinking that they have listed it for a reason.

Small Mark at Courtenay Sport advised me that the 4 or 6 paddle clutches from Helix cope with up to around 400 ft/lbs of torque.
One of the best things your can do to save your clutch is to get the car mapped so that the characteritic torque spike at approx 3500 revs is 'flattened' by retarding the ignition and/or opening the Amal valve (assuming it can open and shut fast enough, which I am not sure about).
Thanks for all your replies I think the uprated clutch will have to wait untill next summer as i have allready overspent and my budget is allready out of the window. And im not expecting my mortgage to be as cheap as it is for much longer.
So that leads me on to my next question based on the remap. If with full miltek and air box mods aka courtneay stage 2 the car manages to achieve 240 bhp 260 ft lb but I want the torque capped at say 240 to be fairly safe that its not gonna go inside of 6 months. Does that also mean that I will have to loose some bhp also.
I know torque and bhp are related but as they give there peak figures at different parts of the rev range are they that closely related that you can't have one without the other. And would this make the car/power delivery feel nasty or odd to drive ideally I would want a torque/power curve that resembles more of a plateau rather than some mountain range. Or is it pointless getting it remapped in this way and should I just put the £500 remap cost towards getting new clutch sooner then having it remaped to its full potential.

Can't fully answer your question but after our remap with Matt Reidy, when it became apparent the clutch was struggling to cope, he offered to tweak the map to reduce boost for no extra cost. Decided to keep it as it was in the end and upgrade the clutch instead (which we're going to have a crack at next week).
