I replaced my belt tensioner with a new one, no difference.

I feel like I am out of options.

I am running stock pulley sizes, stock impeller that came from stillen. Nothing modified there.

Have you tried the "high traction" pulleys from Vortech?

I'm using the "high traction" pulleys on the SC and the serp side but not the jackshaft pulley, but using a larger jackshaft idler pulley (due to smaller 3.0" SC pulley). I'm also using the extra idler pulley for more wrap on the serp side. I don't believe I'm getting any slippage.

Also I've read that CRC will make things worse in the end.
