Car revs faster. Other then that not really. The difference was seen at the track, which in my case equalled and surpassed the performance of removing the cats.

RE: Underdrive Pullys
I plan on doing a dyno after I get mine installed so I'll let you know. Would have been this week while the shop is doing my gauges and such but good old FedEx put it on me![:@] Maybe I'll get them tomorrow!

RE: Underdrive Pullys
Well, the difference is that the engine revs faster. When people go by "seat of the pants" you really need a substantial gain in order to actually feel it. The car feels stronger, feels like it accelerates faster, but that's essentially what the pulleys are intended to do.
I ran 13.2s with an 93 Oct Tune, C&L Intake, and an O/R H. All street trim including spare, jack, and shaker 1000.
Removed the O/R H and I was managing 13.4s. This to me tells me the O/R H was worth .2 in the 1/4.
Installed the pulleys and I am now at my current time of 13.0. I'm sure my driving style has changed with experience, but with that said I still think the pulleys are a great buy. I haven't noticed any elecritcal problems due to the pulleys (slows down accessories, hence how it makes power.) A/C still gets cold on startup, and stays cold... Have noticed absolutely zero negatives about the product. I have the Steeda pulleys, not sure that it matters... You can usually get them on sale for around $200. They go on sale frequently as well.
