So I bought an AMR500 supercharger for a mini cooper or vw. But I am putting it on a 212. I've tried to supercharge this motor before with a smog pump but I spun it in reverse and blew the smog pump up. My engine has Chromoly push rods, 28lb valve springs, stock crank, billet rod, flat top piston, 1-inch exhaust all the way out, ported intake, 2 degrees colder plug, and a 26mm Chinese Mikuni carb. My cam I did myself, I chopped the lobes and welded higher for more lift, the lift is unknown but better than stock. So my motor is pretty built. Im just wondering what other things I should do for ensuring the safety of the engine when supercharging it. Should I run higher octane fuel than just 91? What psi should I not go over? I also bought a boost gauge and a blow-off valve so I can control what kind of boost goes into the engine.
