hi LPH (making me think of fuel pumps for some reason ... LOL)

who did you use for your engine work ?

my current car has 450 hp/ton so I don't know if I should aim for this in my STR or keep it more sensible and just use stock internals on a 3.2 Alfa V6 with a supercharger

I'm looking for a really intrusive supercharger whine ... would the Rotrex give me this or is it more refined ?

cheers

Raj
