I saw this also. One has a completely stock bottom-end according to the owner and putting down like 600hp on Nitrous! How is that possible!? I thought our Magnums were as brittle as a potato chip at any power level above 500hp?
Those who watch this will want to pay attention to his timing curve. He was emailing a tuner (Flying ryan) I believe and reducing the overall timing. Started making power after that. Impressive to say the least!!!!
