How do you go about...?

Twin Supercharging an engine? A 1932 Ford Highboy Roadster just sold on BJ and it had 2 chrome superchargers sticking out of the sides of the engine bay sucking in air

bolt them to the motor, duh!

but for real, that's about all it takes, then you plumb everything in however it needs to be depending on whether it's intercooled or not. so instead of 1 pipe to the intake manifold, you have 2 going in (or 2 in a Y into 1 then into the manifold).

ahhhh i have just never seen 2 superchargers mounted on a motor and it shocked me...2 turbos is one thing but sc's i haven't seen before

where they roots or turbines? if they were turbines, those are super easy to do. i had a set up like that on my crown vic about 5yrs ago.
