Re: Oil
50 weight? Wow! I'd bet that's costing you some pretty serious HP. I've seen as much as 12hp on the engine dyno going from 10W30 to Royal Purple Racing 11. 50 weight must take forever to make it back to the pan, during which its creating windage on everything from the valve springs to camshaft to crank.
