Hot weather and turbochargers ? I'm thinking turbochargers might not be an ideal setup for cars in the South. Any thoughts or comments?

If you're talking daily driver, it won't make all that much difference. A Turbo charger with a properly set up intercooler won't be bothered by heat on a normal day. It's when you are looking for absolute maximum performance, like on a race track or drag strip that excess heat will become a concern. And SUPERCHARGERS heat the incoming air charge too.

That's what charge air coolers are for. supercharging might still be a better option.
