Re: Blower optons, Gen 1 sbc bbc
All kinds of options when it comes to blowers, just need to be honest with yourself and figure out exactly what the performance goal is. Most late model OEM's run a TVS or screw blower (positive displacement blowers, similar to a roots) and sandwich an air-2-water intercooler between the intake and blower. These set-ups are very reliable, but are also conservative with tune due to warranty and longevity, but can be modified for major power. I own a 2013 CTS-V, its bone stock and drives,...well like a Cadillac, lol. But stab the loud pedal and it'll show its teeth in a hurry. Pretty impressive for a stock vehicle with all the amenities of a Cadillac.
I also have a BBC with a F2 Procharger (centrifugal blower, design is similar to a turbo) Completely different animal. Mine is noisy, hot, obnoxious, 4 digit HP and yes, its fun, but not something you'll drive often. They do make a variety of centrifugal blowers that can be very tame and excellent for street use.
So that's basically it, you have the positive displacement blowers which make the power the second you stomp it, or the centrifugal compressor blower, which softens the hit a little bit, and comes on strong as RPM builds. You just need to figure out which design best fits your application.
