STFU yudalicious, i know who you are...you tried to run me on 85 and BOOM! Some shit flew out from your car and you startin smokin like a fuckin rasta convention...I pulled over and picked up what flew out. Guess what?!?!? You DIDNT BOLT ON THE EXTRA CYLINDER RIGHT BIATCH!!!! Now it sits on my desk as a reminder of how stupid some ricers are. I TIG welded my last cylinder add-on using a titanium rod and a Lincoln 1230 mW welder, and I'm running about 45-50 psi now no problem (not exactly sure how high b/c my autometer boost gauge only goes to 45 and its MAXXED out). Bolt on cylinders? I think my mountain bike is faster than that rig
