Oil temps: 335 comparitive observation.

Jordo! Good demonstration of how the undertray does not need to be removed for an oil change! I only discovered this at my last oil change & it saves many minutes messing around with the million screws and the flappy cover.

I had the sudden severe throttle lag thing again tonight. It felt like the CVTC system was stuck in the high rpm mode so below 4000rpm there was a very flaccid response. Foot to the floor in 1st got me nowhere quick but once about 3-4k the motor came to life although not as healthily as it does normally. i had to restart the motor to remedy the problem.

Prior to changing to Nulon oil, it felt like the CVTC system was stuck in the low RPM mode so above 4k felt reeeeeally flat. Like as if a piece of wood was wedged under the pedal.

Anyway, my 25 row Setrab core has arrived and i will be putting together a custom oil cooler set up as the commercially made kits all won't fit my car due to my ram air scoops

Hm. And VDC was off? I've only ever encountered any major lag if I floored it and the VDC was on -- this is even on OEM throttle map

i usually drive with VDC on and on both instances the VDC light was not blinking. Nor was there a loss of traction but i guess the sensation is similar but i wouldn't say it's the same because usually when VDC kills the party, the gas pedal literally stops responding.

Right -- VDC (brain fart on my end).

Slip light or not, VDC could still be affecting things. Try it with VDC off?

when it happens again i'll turn off VDC and see what happens.

It also feels like what Digitonium described he felt when his brake switch was defective and i think one other chap had a dud brake switch on his twin turbo Z which caused constant throttle lag. What i don't get is why the problem ceased this time after a restart

So are we saying that the water to oil cooler is only on the newer Z's and it does not work? Or has it mostly solved the issue?

i've never tracked my car but my car is my daily and it's been thru 2 blazing Aussie summers already. Oil temps i've seen go up to 110*c/230*F with the factory oil to water cooler.

From my experience with it, for most people it will keep them out of trouble but if you do track the car or drive with a heavy right foot then an oil to air cooler is a worthy investment.

But for me and my quest for moar cool, i will be ditching the factory cooler for a 25 row oil to air cooler. I have the core, just need to fab the brackets and get the hoses made up.

Oil choice does play a big role in how much pleasure you'll get before things get flaccid though. Some oils take longer to heat up whether it be just characteristic or a sign of a better oil being that less engine heat must be due to less friction. I wasn't happy with the Nissan 5w30 we get here so now i'm using one of the local brands and it's the best i've used so far!
