Looking for recommendations for a supercharged Alfa

[Bill-Sims]

I run an Alfa 3 liter sedan in autocross, and am in process of fitting an Eaton M-62 supercharger. Engine has a modified Bosch L-Jetronic with larger AFM and larger injectors and reset parmeters. Is not "tuneable" by laptop. Planning on 5 to 6 psi boost. Car does a 1 minute run about 8 times/month, and I'm at WOT only about 15% of the time. Idles about 15 minutes in grid during each event.

Is not driven on the street.

Is the Aqua Mist 1S the best for my application? How much should I pay in USD? Who is a good source?

Thanks!
