I am interested in hearing what the membership feels about supercharge vs. turbocharge. In 1979, I installed a turbo (non intercooled) in a 1977 Datsun (Nissan) 280Z. While there was great power, there were issues of turbo lag and underhood temperature. Turbo power is not "free" as there is increased exhaust back pressure. The car ran well for five years. The guy I sold it to blew the head gasket within 3 months. I drove a Mercedes C240 with a supercharger and it also performed very well. The supercharger seems to have the advantage of quicker power, lower under hood temperatures, and better control of boost through gearing and pulley size. Any thoughts?
