Were you advised to protect the driveshaft (when it is in the car) in anyway or does the driveshaft already have some sort of protection over the CF section?

I have been told that CF tailshaft don't like scratches and dings.

i dont think he has a CF tailshaft...

well if they didn't say anything its probably ok then.

My previous employer had a carbon fibre tailshaft in his race car. They used to wrap it in cellophane to stop it getting chipped. any major scratches can weaken them. Once a guy that was working on the car put a screw into the transmissin tunnel, from the inside of the car, it stuck into tailshaft and put a gouge into it. One new tailshaft later...

I think you are getting a bit mixed up.

Fibre reinforced materials are usually much better than their equivalent homogeneous counter parts as far as crack propogation resistance is concerned.

Unfortunately they are not so good when basically sand blasted. This can remove the resin from around the fibre reinforcements & then allow the component to fail. As Rolls Royce discovered on the RB211 before they went bankrupt.

      Need AC Compressor for R32

      By silviaz · Posted

      Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By silviaz · Posted

      Ah, to clarify if the car has already been tuned and has been modified and you want to go from a oem cat to a 100 cell or decat or vice versa.Are you saying that the car doesn't need to be tuned after a cat change if it's already been tuned?

      High temp brake fluid?

      By Komdotkom · Posted

      This has been covered a bazillion times but google wet boiling point vs dry. Motul is only good when it's fresh, once it absorbs moisture it gets pretty average very quickly. So as above, make sure you change it if you're going racing. I run the Endless brake fluid in mind, but only because a mate is a distributor and it's cheap. It's not quite as good as SRF but I'm running 380mm rotors on a Skyline so it's not like they get hot.

      Does 98ron contain ethanol?

      By Kinkstaah · Posted

      That's the thing, they still add it and it makes fuel cheaper, implying adding 10% of it drops the cost of 91 by what, 5c a liter? I remember when it was barely half the price of 98. Because you know, 85% of what is in the fuel is way cheaper than 91 fuel is by volume.

      Need AC Compressor for R32

      By GTSBoy · Posted

      Auto electricians that do repairs on automotive AC systems can source service kits. I don't know where they actually source them. I do know that there is one available for the R34 comp that I would need it for. If you have to pay someone to dismantle, clean and do needed repairs and fit kit contents, then you'd probably end up spending a good fraction of the cost of a new one. I would not be paying for that, because I would be doing it myself. My mechanic (bro-in-law) will happily source what is needed. Back in the day (like in the 80s and 90s), rebuilding an AC compressor was the standard approach, same as for starter motors, alternators, etc, because new replacements were v. expensive. After the China manufacturing boom and the rise of the disposable approach to everything, people just started throwing broken/worn stuff away and not rebuilding things.
