is this a good turbo choice?

I don't know one turbo from another, but I have a Vortech V-1, S trim centrifugal supercharger on a 360 Magnum that is stock except for the cam (very mild Hughes) and I can tell you one thing.

You are gonna LIKE what 8 pounds of boost does for your sedan! I run 10 pounds of boost and I'd bet that 8 pounds from a turbo would pretty much equal 10 from a centrifugal blower like mine, as regards horsepower output, because of no parasitic drag.

It transformed my car; took it from 13.35 to mid 11s, and from 102 mph to about 118.
It's a different car. You won't believe the difference.... My car is a 3,400-pound '72 Valiant 4-door.

Good luck!

Bill
