I have a 2003 svt cobra convertible with 12,000miles. Had it dynoed this summer and it dynoed at 445RWHP and 474Lbs torque.
The only modifications are as follows:
1. Steeda cold air kit
2. Steeda 2.81" Supercharger puller and belt tensioner
3. Flowmaster exhaust system.
I would like to get RWHP up to 500 and torque about same. Any suggestions as to how to accomplish this.
