Hi all,

Does anyone know a place (Syd preferably) i can source some PTFE/ teflon insulated wire to re-wire my 040?

Seems like PVC insulated wire does not like fuel very much.

Cheers!

No it doesn't. PVC insulated cable will break down in fuel. I have now looked into find a replacement PTFE/Teflon coated cable. I have sourced some here in Adelaide at Key Tubing and electrical in Melrose Park. I'm an electrician and i work just around the corner from them.

I got a price, for 4mm2 available in black, blue, white and two other colours from memory. No red, is $4.40 per metre. So $440 per 100 metre roll. I have spoken to one of the guys down there, and he seems to think he'll be able to sell it by the metre.

Now, in reality 2.5mm2 will be fine for a single 040. 2.5mm2 cable is rated at 20A without taking into consideration any cable de-rating factors, and in this case; being a car with a maximum run length of probably 5 metres, we dont need to.

I didn't get a price on the 2.5mm2, but its available in black and red, and i would assume it would be around the $3 - $3.50 per metre.

I think i'll be getting myself some for free as we're such a big customer of theirs rofl.gif

Failing this route, i do believe RS components sell it, i think they are based somewhere in Sydney from memory. Maybe Silverwater.

rated to 20A for 240V AC? 12V DC is very different....

Usually there is not consideration for the type of current draw or the voltage. If its AC or DC, 20A is seen as 20A. 2.5mm2 will easily support this.

Gauge, why does everyone use gauge? Its American, we're Australian. Cable is measured in Cross Sectional Area, not a numerical number denoting the size of a cable that works in reverse.

      I used the radium thing, makes the whole parallel assembly a lot more compact compared to any other way of doing it

      Racetronix also sells those ethanol content sensor bypass blocks. Adapter, Flex-Fuel E85 Sensor High-Flow Bypass, In-line No Sensor (ADF-FLEX-NS): Adapters - Flex Fuel | Racetronix Ethanol content sensor are originally designed to be on the feed line. These bypass blocks are meant to be ran in the feed line and not return. The continental ethanol content sensors have a 3/8" ID and not 5/16". This is why they are ran on the return line directly in conjunction with a low threshold sampling value VS in the feed with one of these blocks.    Haha we think alike, I used both original feed/return for 8AN feed, and one of the Hicas lines as a 6AN return. I also capped off and left the other Hicas line as a spare.

      R32 gtst speedo out by 10kph

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.
