Well, in all honesty, I'm not really that concerned with added HP, as this is a daily driver and never raced. With that said, maybe I should put the stock pulleys back on, at least until I get the cooling issue resolved and get comfortable with the temp ranges of the new motor. The car had the UDP's on it when I bought it, but the previous owner threw in all the orginal parts he had pulled off, so I do still have the stock pulleys.
It's funny how things change with age. When I was a teenager, all I could think of was new ways to add HP, but now at 40, all I think of are ways to make it more reliable. LOL!
