What is a better choice for 2007 v6, supercharger or turbo?
Depends on what your trying to build. Absolute most power or good reliable power. Turbo will net the most power but there have been a lot more guys blow up there V6 with turbos then with superchargers. I have 134,000 miles on my 4.0 with 104,000 miles my X-Charger currently running 330RWHP and I pound the crap out of it! I don't know of any Turbo 4.0 lasting anywhere near that long but they sure put out some high horse power for a while.
