Merlin's 4G Time Attack Lude

[wurlycorner]

Isnt there some fire risk with waterless collant?

It's more flammable than a water based coolant, yep. But nothing like as flammable as petrol or even diesel, so it's the least of the worries under the bonnet
On a new build that's going to be driven hard, I reckon using the Evans stuff sounds like a good thing to do?

My problem with running it in my cars is that I couldn't be sure I'd reach 97% purity (extraction of water) and the cost (I can't see me not having to change something on the cooling system in that time, so lifetime lasting doesn't help there).

I do want better corrosion protection though, given that I have lots of cars lots of them unfortunately sit around for ages (not good for the cooling systems so I've been thinking of running this in addition to standard antifreeze;

Much cheaper and should do the job I need, nicely.

Cheers dude. I'm buying a new clutch kit and flywheel today It should be all ready for the first race but if the wife gives birth in the days before it I wont be there to race It shouldn't impact the season though.

have you taken the gearbox out and had a look at the old clutch and flywheel?
would be interesting to see whats gone wrong...

It is happening very soon. I have come to the suspicion that the Fidanza alloy flywheel and Competition Clutch pressure plate have come apart again. So to save time (and eventually money) I am binning the lot and buying new. The only part I am keeping is my ARP flywheel bolts. I have since heard a few negative stories about the Fidanza alloy flywheel.

This arrived today, Competition Clutch Forged Steel Ultra Lightweight (4.08kg) flywheel





Through experience I knew to check what the timing marks looked like before I install it


Some other bits I have got that is needed to install the new bits, new OEM pressure plate bolts and ARP assembly lube.

That flywheel looks the biz

im sure the fidanza one looked very different in design
maybe more suited to fast road and not up to the hammering you give it out on track

p.s love the clear timing marks

[wurlycorner]

Looks awesome

[Doggo]

Now, that's a flywheel right there.

Nice, I got one of these but think it might be a little ott for road use, I have the cc lightweight one for the crx but haven't fitted that yet either so don't have much for comparison.

[farlow]

Also I believe the fidanza on is of partly aluminium construction, that's why it looks different to the competition clutch one. I much prefer the construction of the competition clutch flywheels.

Never had an issue with my Fidanza. Must have 15k on it now.

Yeah the Fidanza is an aluminium flywheel with a steel face bolted to it.

My current Fidanza


I think the problem I am having is that the Fidanza was 2nd hand so I don't know its history. I also think that the alloy will not have as great a heat range as the forged steel (a good example of this is wheel nuts). I think at extreme temps the alloy cannot take it, hence the slackening of the pressure plate bolts.

maybe more suited to fast road and not up to the hammering you give it out on track

Yup my thoughts too.

Yeah, I was thinking of fitting the Fidanza flywheel I have for my 4th gen to the 5th gen as and when I get a new clutch now instead actually. Quite fancy a Competition clutch one and I was going to go competiton clutch clutch anyway on the 4th.

How much was that Ultra light FW Merl?
