My car is normally brilliant with intake temps only reaching 120 degF at WOT @ 60 degF ambient. Tonight however it really struggled with 120 degF whilst cruising @ 30 degF ambient. Underneath the bonnet was like an oven when I stopped and when I put my foot down it felt slow and stty. In my mind's eye I could see Ringham nodding and stroking his chin in a "N/A (see what I did there?) would be more efficient you fool!" kind of way.

Why do these things get so hot under the bonnet? Don't want to cut the bonnet so a chiller is definitely on the cards. Mark's getting one soon I think?

No IAT issues here (being not applicable...) but my engine bay gets appreciably hot, even standing next to it after a gentle run. Nature of the beast?

Yep and to think they are made in Australia? The cooling system works but I cannot help thinking GM dropped an airflow bk when they stuck that V8 in that engine bay!

Yes, it's all fine. Just making an observation of how a few extra degrees ambient has an exponential affect on AITs which in turn pulls loads of timing and ruins performance. It is the hottest day of the year and I'm running 14psi so not unexpected.

I fancy 70 deg IATs all year round.

That's only 48 C. Shouldn't be pulling timing yet.

That's where my temps were at yesterday as well at idle in traffic. Once I got moving again then I got back down to 97-100*.

Yes but at WOT it went from 120 to 150 where I think it does pull timing. Not normally a problem but this hot weather kills performance.

IIRC timing starts to deteriorate at above 65 Deg C

Actually OEM is timing goes south from 30*C

So 48 will be pulling a lot, 35 not so much..

Unless its been messed from stock..
