Power Lost On Hot Days!

[SECURITY]

I never like this idea. Performance is total. What if it was 39⁰ on a well planed track day? Would you baby your car? Thats for aftermarket (or PFC) knock sensors are for (not to mention human ears) I reckon the idea's to tweak your inlet temp correction to counter hot days. End results are end results, anything you can make compared to the guy next to you, is a profit smile.gif

track day is constant high speed which means constant airflow and you get a cool-down lap as well. on the street its start - stop, start - stop. giving it a hit on a hot day then stopping at a set of lights will put all of your hardware to the test.

for example, it was a hot day and i was babying my car through the streets of the gong as it was a HOT day. on my way back up to sydney i went through nasho and had a bit of a go. i had no fears because i knew my radiator was getting enough air to keep my engine cool.

at least on a track you've got the cool down lap to just cruise at a low load with constant airflow still coming at you... THEN stop.

i see your point with the intake temp adjusting and thats what i've set up on my car, except on my gtst it has to be water temp (no intake temp sensor). i just advise anyone without the gear to play your intake/water temp adjustment maps to take it easy.

"When the engine is switched OFF, the cooling system becomes inactive and the residual heat in the engine from the block, head and exhaust manifold are transferred to the coolant and other engine components. The engine temperature actually increases after a hot engine shutdown. This is called 'afterboil' or 'heat soak' and can be damaging to engine life."

Ahh but you see the cooling system does not become inactive.. It begins a process called thermosyphoning, coolant still circulates removing heat from the turbo's core.
