Right, time for another update.
I have been monitoring intake temperatures over the last few weeks, findings as follows:
> In easy driving through town, the intake temps average about 5-7deg C above ambient.
> The highest temperature recorded was 45deg C. This was a 3rd and 4th gear climb up a hill on the highway.
> What was interesting to note, was that sitting in peak traffic for long periods of time, where there was no airflow through the engine bay other than the cooling fan kicking in, the intake temps never went above 28deg C.
So that concludes that section of my testing. Going forward, I will move the sensor to where my cone filter sits, to see how the underbonnet temps vary. Basically to see what the motor is sucking in BEFORE the temperatures get affected by the hot turbo and other parts.
Then the long term plan - to build a heat shield and see if that makes a difference. I have no space to fit an airbox, so will need to fabricate my own

(I've started on the template, but as time allows, I will progress on that).
Anyway, I've also been doing some research into something I have been wanting for a long time. And finally I found it - Hen's teeth:
Lol, jokes aside, I decided to spoil myself for my birthday, and got this:
This is a genuine Meriva OPC steering wheel. Now these are as scarce as hen's teeth, because from my research, it seems that Opel only made 300 Meriva OPCs. So I'd like to think I have a collector's item :rollsmile:.
When it came to fitting, I had to buy a few extra bits locally, like the airbag and the slip ring (my Ute is the base version, so no luxuries, or safety items like ABS or airbags).
Here I had stripped off everything:
Slip ring fitted:
Wheel fitted:
The steering wheel is similar in design to the standard wheel, but it is MUCH thicker, and obviously covered in high quality leather, with silver stitching.
Here's a pic of my old wheel for comparison:
Overall I'm happy that I did it :joy: There will be some other bits coming for the interior as well - that's for future updates...
