Carbs are a blessing, especially in the mountains. We live at 8,000 ft above sea level and the pass is 11,200 ft. With carbs you need high altitude jets. A hassle to change back and forth. Turbos have good points and bad points. Yes you get more power at altitude than na but there is also turbo lag and less aggressive sound and lower revs. That said we have three cars 458 Spider na Audi S4 supercharged manual transmission Audi S5 turbo charged tiptronic transmission While the turbo has very little lag the supercharger has none. The turbo has a little more hp and torque but cabrio iweighs more. The S4 handles better through the twisties and is more fun to drive. But not more fun than the 458. Not even close. Nor should it be since it costs 4x as much but worth every penny.
