Anything is better than atmospheric pressure, if it aint booosting atleast its assisting, remember its going just to one cylinder at a time. I have a Latham five carburator supercharger, air comes in the front and pushed out the back. Eliminate the top carb so I don't have to cut a hole in the hood and just use one Carter on each side, the other two will just be for show. Line up the pulleys and plum the some intake tubes back to the front.
I have EA81 apart in a basket going to bring it to my VW buddy and see what VW performance parts can be re engineered. Like a steel crank, lighter push rods, roller rockers, bigblock valvesprings, and cams. Fuji must of bought the rights off of VW 1200 back in 1965ish and watercooled it. My EA81 looks like a backwards Superbettle to me, IRS transaxle, torsion bar suspension, and struts.
