I had the stillen pulley on for about 5,000 miles before going TT, 2000 miles later it appears I have rod knock. Car is only making 500whp (dynojet) and the tune I was running from GTM was pretty much spot on so this seems unlikely to be a factor in the demise of my bearings; right now I am inclined to blame the pulley.

In related news, stay tuned for an engine build thread
Which pulley? The crank pulley?
