Whoa, great numbers/clean install. I'm impressed.
I really think the snout pressure on the crank is what helps murder OPG's and the sprocket. Considering belt driven superchargers drive load thru the roof and balancers carry much of that, it's not surprising people disintegrate parts nearby.
I have a feeling you'll be alright till you tear down/swap the longblock out.
seen plenty of TT cars break OPGs.....appears RPMs has a contributing factor as well
