Probably a dumb question:

Does a cooler climate affect the performance on a turbocharged engine?

Well it won't really affect the performance of the turbocharger, but cooler air generally results in slightly better performance for both turbo and N/A engines.

I kindda knew about N/A engines since that's the idea of cold air intakes. But was wondering if a cold weather would have sort of the same effect as an intercooler on a turbo engine.

Thanks for the input.

Rain hitting the intercooler makes more power. Cold weather also makes the car get some more boost. My friends wrx gets noticable added boost from rain or coldweather.

yes, colder air makes a better boost. that's because when air is colder, it's obviously more compact, so even more air can be forced into the engine if the air is cold.

Like everyone else has said, colder air = more oxygen, which in turn creates more power, no matter if the engine is turbocharged or not. Weather in the racing world has a huge effect on setups. For example, Colder air makes the engine make more power, but it also makes it harder for the car to cut through the air. Everythings a trade off, it sucks.

does colder air prevent or induce knocking, since knocking happens when the air fuel mixture is too compressed/"hot" i'm confused as to whether the denser air would be a hinderance or beneficial to performance

colder air does give some performance, since theere's more particles compared to hot air, denser meanin more compression and more power, i did notice that when goin to the race track(1/8 mile), my brother was makin less times at night than at day(air was cooler at night), also noticed when we did the dyno to that car(mustang GT), there was a 2-3hp loss after each run cause the engine comparment was hot after the first and 2nd run.

Knocking is the same as Detonation (If I rememeber correctly) and detonation is defined as a hasty burning or explosion of the mixture in the engine's cylinders. So, since colder air makes the mixture combust better (because there's more oxygen) knocking is eliminated or reduced.
