Ah - a loaded question. Well, several years ago I was on the race team for the world's quickest Nissan, a 350Z that did low sixes at over 215 mph. A twin turbo, methanol 230 c.i. V-6 that had Carrillo H-beams. At the time, we were putting over 350 rwhp through EACH rod . . . actually, the car made 2200 rear wheel. Partly based on that I personally lean toward Carrillos. That said, I have Wossner rods in my 600 hp Ultra street bike and Carrillos in my 580 hp shootout bike. I guess I haven't really made up my mind . . . what was the question?
