Woody - interesting info; thanks for sharing!!

Maybe consider the C3P "mid-sized" S/C pulley? Allegedly, they were working on an option for larger-crank-pullied cars... size-wise, between the C3P S/C pulley currently on the market, and the stock S/C pulley. This could give you the boost level you're looking for, without overdriving the accessories as much as the 185mm crank pulley set-up (i.e. fewer parasitic losses). OTOH, 185mm is obviously more proven than a currently "vaporware" mid-sized S/C pulley - so that might steer you back to the 185; food for thought...

Thanks again for sharing your findings - I have a feeling your R&D is going to help A LOT of folks who're having high-rpm lean issues (who wouldn't have fixed it otherwise)... kudos to you, sir!
