Ferrari Mailing List: Re: 308 Mods

[Alan M. Tebby, D.C. (atebby]

Actually a supercharger is a great way to get extra performance out of any 
engine. For those of you who are a friend on facebook, in one of the albums 
I have a picture or two of a supercharger that I put on my motorcycle. The 
supercharger adds some horsepower but it's real advantage is torque, so when 
you dyno the vehicle, ask the operator to switch the scale from horsepower 
to torque and compare before and after, it really is amazing.
