Are you running the stock blower pulley? I wouldn't expect much slip on stock. However, after I upgraded to the smaller Chicane pulley on my '01, I started noticing/feeling slippage which became even more apparent during dyno testing. Additionally, I was using a 111 belt and was slill getting slippage.....
