Silver C70 T5 - Manual - 400BHP

**Wobbly Dave** · Wednesday 9th February 2011, 12:43

I am going with a HD sachs organic centre plate & clutch cover plate - reinforce rivets & springs, as recommended by the guys that did my remap. It's a fast road set up rather than an out & out paddle clutch for racing. Heavy duty but still with the road worthy element included, rate to 500NM so it shouldn't slip.

It will be fitted at HLM on the week starting 21st Feb.

Still uming & arring about the flywheel. Already have a SMF.

while your doing all that & they've got the gearbox off you might as well do the lot & put a lightened one on, how much is it going to cost in the future to remove the gearbox again just to do the flywheel do it now while its off anyway

I looked at your link & I am baffled by the choice.

to TTV? All i'd do is standard flywheel weight with a few kilo's off, that'll be more that enough to notice a difference

Dave if you've got the gearbox off then you might as well replace the rear main seal if it has'nt already been done too.

I am certain the rear main seal will be done.

I am not changing the flywheel.
I don't have a racing engine that revs to over 8500K & just adding parts for the sake of it seems silly. If this was a full blow race engine then I could see the point. As it is the cost of getting this in is almost as much as the car is worth.

So long as the current FW is in good order - the benefits are outweighed by the cost.

Nah... gonna save my 400 quid & take the wife on holiday (as promised).

Still I am excited about the new GB.

Thanks as always for your input.

It's going in this week!!

Well it has been wee while since a full update.

I got a new half & half interior from Spesh - due to his C70 being demised by a Laguna.

The new gearbox, quaife LSD & performance clutch is in. The revamped gearbox is disappointing. I am not sure what happened - & after 2 weeks of trying to contact the gearboxman.co.uk concerning the refurbishment I have had no reply - despite follow up phone calls. I will persist. The gearbox feels notch & drops out of 2nd gear whilst decelerating under engine braking.
I have still to find a resolution for it. It doesn't do it everytime & it is irritating rather than dangerous.
Perhaps the worn bushings are not helping. I hope to visit my father soon who has promised to mill me some. The quaife diff however is brilliant. The pull around corners is substantial & immediate - understeer is almost eliminated. I am scared however that when grip is lost it will go in a big way. The clutch is very direct & needs more leg power than previous. When slipping it in reverse to get on the driveway it really stinks!! However I recognise this is a small price to pay given the higher clamping force. Getting used to the clutch is not made easier by the notchy 1st gear.
I have had a new DMF (dual mass flywheel) fitted on advice from Sachs in Germany. This should help dampen some of the wash back through the transmission. Sachs said that a SMF would almost certainly damage the engine - snap the crank.

Net result is a much faster car off the line. Whole thing seems a lot faster overall - like none of the power is being wasted. It is a real shame about the gearbox but until I have had full discussion with the firm in question - it is not possible to work out the root cause of the issues. Not very impressed with the after sales care. Given the budget involved this is not the last you will hear of this. I am not usually one for airing my grevancies online & I hope that all will come good in the end.

I am certain that these issues will not stop me getting a better launch & the box has improved since Hamish fitted it. First big test will be at Cadwell Park.

Hamish must be thanked for helping getting the box fitted with all the new parts. Stirling job as ever. Even cured my ARB clunk (IPD HD ARB fouling on the shield for the steering rack box).

Anyway - I cleaned her up today. I have also bought a rotary polisher & a De-ionising unit (to lessen the 300 PBM hard water we have here). Drying the car especially in the summer is a really pain due to excessive water spotting. Anyway 0 total dissolved solids here we come curteousy of a 11 gallon DI unit.

looking very nice Dave,what was your old interior? full leather?

**JelT5** · Monday 14th March 2011, 07:42

Car looks great Dave. Very tidy mate

That's a real pain about the box though. I Hope you get a satisfactory response from the company in question. What is it with people and the lack of customer service when you hand over your hard earned?!

sorry to here about your problems mate but at least you can drive her now when are you going to get the final custom remap on her ready for york i hope

I am very much at the mercy of the guy in Sweden. I am hoping he will come over this year & we can finish the map off. Timetable is open wide.

Erm, HAHAHAHAHAHAHAHAHHAAHAHHAHAHAHAHAHAHAHAHAHAHAHAHHA

**Wobbly Dave** · Monday 14th March 2011, 16:38

So I take it then u have another view on harmonics?

**T5frankie** · Monday 14th March 2011, 16:45

the dual mass flywheels were fitted to the v70 lsd versions and the awd's so they could cope with the extra stress that they created dont know wether i'd want an smf on mine

if you get a ttv racing smf you would have no probs they also do dmf too

the advantage is that they rev quicker dont they being lighter?

**T5frankie** · Monday 14th March 2011, 17:05

where are your nice wheels gone mate?

**Wobbly Dave** · Monday 14th March 2011, 17:06

Exactly the purpose of the DMF is to dampen any vibrations and drivetrain feedback. Sachs also said that it was likely to create a lumpy idle if a SMF was used in this application, namely fast road n occasional track use. As I have no expertise in this area I have gone with that recommendation.

Its all pretty academic now
