Season is over and I feel I can give these a fair review. Made just Over 1050 who. Easily over 150 passes on the engine. On 44lbs of boost. And these have been flawless. My only gripe, which isn't their fault, is being steel rods. Bearings wear out fast. Went through two sets of bearing. First set was after 12 or so dyno pulls and 20 passes. Second set was at around 110 passes. I'll be opening it up for a full refresh I've the winter and I expect to be replacing them again. But I'll take that over an aluminum rod setup that has a shelf life itself. I'm also spinning this at 9500rpm on a k24. On the arp2000 bolts. I know I'm flirting with disaster but that's the game we play and so far these rods have over performed for me.
