The OG LS alternator.

Seemed to be the best value for money.

The old drive belt doesn't fit now though 🙃

Is it too long?

nah too short, have gone to a 4PK 895 from an 875 and all good now.

The real question is, is the voltage still dropping...

still not sure, did a log and it didn't save or i did something wrong...

Away for work for a week and will hopefully try again logging soon...

How long should oil 'typically' take to get up to temperature? ~75 - 80 degrees?

After 10 minutes of idling and then 15-20 minutes of sedate driving I'm lucky to get oil temps up over 60 degrees and i don't even run an oil cooler...

It does depend on outside temps, but no more than 5 minutes to be at operating temp....is your gauge working correctly?

Measured this at some point in my car. I think it was 9 minutes to get to 65°C on a 12°C morning. City-driving. And it feels like an eternity.

Where is the temp sensor located?
I've found in the sump takes a long time and in the oil filter housing around 10-20 mins pending weather

This is reading directly from the link on my laptop whilst live monitoring

The sensor for the Link ECU is located on the turbos oil feed line...

Finally hopped back on the dyno..

The LS alternator upgrade and going to a heavier gauged direct feed wire for the fuel pump solved my voltage drop issues...

Managed to squeeze a few more killerwasps out of her but the turbo is getting out of it's efficiency range now, nevertheless she feels great.... The new RE71RS' vs my 10 yr old RS3's probably don't help the power figure either but that is here nor there...

Now just to monitor and keep on top of oil pressure issues, I'm running Penrite ten tenths 10W50 overfilled to 6L and it's getting very close to the cut (obviously not ideal) but my last resort before going bigger sump is to follow the Motive recommendation of going to a 10W60...
