Hi everyone,
I ran the Saleen on a dyno and was a bit disappointed on the results. As per Rob Wetzel who was a partner at SVC in Scottsdale here are his thoughts:

*The car was driven to the dyno and it was allowed to cool down for 30 minutes. The room temperature was 95 and based on his calculations if the temperature was 60 and the car had been tested with an overnight stay he believes we would have had another 35HP.
*His tune was set for 91 octane and for some reason with high gas prices I decided to try Costco gas and realized half way through it was 89 octane and the car was pinging on that gas. This probably has a small part in all this.

The final numbers turned out to be:
327.30 RWHP at 352.83 Max Torque.
A rough estimate is a 20% loss at the driver train so the engine HP is 393.
