I have an application that is client script heavy. When logging into the site, the client pc cpu usage spikes to 90%.

Users connect to the application over a citrix box.

I've played with ACT and get lots of stats about the impact the application has on the server. Is their anyway I can set up ACT to simulate 100 browser connections and than test the impact on the client?

This way I can see the impact opening 100 browser connections and browsing to the application would have on our citrix box.
